Air Pollution Solutions

While air pollution is a serious problem, it is a problem that we can solve! In the United States and around the world, people are taking action to reduce emissions and improve air quality.

The Clean Air Act: How Laws Can Help Clean Up the Air

Creating policies and passing laws to restrict air pollution has been an important step toward improving air quality. In 1970, fueled by persistent visible smog in many U.S. cities and industrial areas and an increase in health problems caused by air pollution, the Clean Air Act paved the way for numerous efforts to improve air quality in the United States. The Clean Air Act requires the Environmental Protection Agency (EPA) to set air quality standards for several hazardous air pollutants reported in the Air Quality Index (AQI) , requires states to have a plan to address air pollution and emissions reduction, and also addresses problems such as acid rain, ozone holes, and greenhouse gas pollution which is causing the climate to warm.

Since the Clean Air Act was passed:

The amounts of the six common pollutants in the atmosphere measured by the EPA (particulates, ozone, lead, carbon monoxide, nitrogen dioxide, and sulfur dioxide) are declining.
The risks of premature death, low birth weight, and other health problems due to air pollution have decreased.
Vehicle emissions have decreased, despite increases in the number of miles driven each year, due to stricter emissions standards and increased efficiency in vehicle engines.
Emissions and toxic pollutants (such as mercury and benzenes) from factories and power plants have decreased, due to new technologies.
There is less acid rain, due to decreased power plant emissions.
The ozone hole continues to shrink as a result of banning the use of CFCs.
Pollution-caused haze in cities and wilderness areas has decreased.

Most industrialized countries have laws and regulations about air quality. The United Kingdom first passed its Clean Air Act in 1956 following a deadly smog event that killed many London residents. In China, where rapid industrial and urban growth in recent decades resulted in a sharp decrease in air quality, numerous laws about air pollution have been passed, including a frequently updated five-year national plan to meet target reductions in air pollution.

It is important to note that while laws and regulations are helping, the effects of air pollution are still apparent. The decline of toxic air pollutants and health improvements are welcome changes, yet the growing threat of climate change due to fossil fuel emissions remains a problem that still needs to be solved.

There Are Many Solutions to Air Pollution

In order to improve air quality and slow climate warming, change needs to happen on a national and global scale. However, actions at the individual and community level are also important.

Burn less coal. Pollution from burning all fossil fuels is harmful to the atmosphere, but burning coal has a larger impact on air pollution than burning oil or gas because it releases more carbon dioxide, sulfur dioxide, and heavy metal pollutants per unit of energy. Also, over one-third of the electricity produced in the world comes from burning coal. As of 2014, the global demand for coal is beginning to decline. In North America, coal plants are being replaced by natural gas. Some countries, such as Japan and South Korea, rely more on nuclear energy, and there is a global increase in electricity supplied by clean, renewable sources like wind, solar, and water.

This is an illustration showing ways that you can help reduce air pollution: wind turbines are a source of renewable energy; drive low pollution vehicles; choose alternative transportation modes, such as walking, riding the bus, or riding a bicycle; refueling in the evening; and around the house choose low VOC products, use less energy, forgo the fire, and mow the grass in the evening.

Conserve energy — at home, work, and everywhere! The demand for electricity, which is most often produced by burning fossil fuels, has grown exponentially over the past decades. Conserve energy by turning off lights, buy appliances rated for energy efficiency, and keep the thermostat set higher in the summer and lower in the winter. Whenever possible, invest in renewable energy sources to power your home. Several countries are using renewables, nuclear power, or lower-emission sources like natural gas to meet their increasing power demand. And many countries plan to significantly increase their use of renewable energy sources in the future.
Monitor air quality warnings and take action on poor air quality days. On days when pollution levels are high, taking action can help reduce the risk of harm to those who are most vulnerable. Reducing overall car usage and avoiding idling your car can help on days with high levels of ozone pollution. Save refueling and use of gas-powered yard equipment for the evening when it is cooler and ozone levels are lower. On days when particle pollutants are high, avoid burning yard waste and wood. Choosing to carpool or using a clean transportation method is always helpful, especially on days with high levels of air pollution. Check on the air quality in your area at the AirNow website .
Take action within your community to find solutions to air pollution. Around the world, many of the current solutions are the result of communities coming together to demand change. Citizens in Shenzhen, China, inspired a switch to electric buses in their city. In Brussels, Belgium, a movement started by parents concerned about poor air quality in schools led to a plan to invest in public transportation and bicycling, along with a ban on fueled cars by 2030. And in many countries, governments are closing coal plants and exploring new sources of energy because of citizens who are concerned about climate warming.

Air Pollution Essay

Essay on Air Pollution

Environmental changes are caused by the natural or artificial content of harmful pollutants and can cause instability, disturbance, or adverse effects on the ecosystem. Earth and its environment pose a more serious threat due to the increasing pollution of air, water, and soil. Environmental damage is caused by improper resource management or careless human activities. Therefore, any activity that violates the original nature of the environment and leads to degradation is called pollution. We need to understand the origin of these pollutants and find ways to control pollution. This can also be done by raising awareness of the effects of pollutants.

Air pollution is any physical, chemical, or biological change in the air. A certain percentage of the gas is present in the atmosphere. Increasing or decreasing the composition of these gasses is detrimental to survival. This imbalance in gas composition causes an increase in global temperature which is called global warming.

Introduction to air pollution

The Earth and its environment are facing a serious threat by the increasing pollution of the air, water, and soil—the vital life support systems of the Earth. The damage to the environment is caused by improper management of resources or by careless human activity. Hence any activity that violates the original character of nature and leads to its degradation is called pollution. We need to understand the sources of these pollutants and find ways to control pollution. This can be also done by making people aware of the effects of pollutants.

Air with 78% Nitrogen, 21% Oxygen, and 1% of all other gasses support life on Earth. Various processes take place to sustain the regular percentage of gasses and their composition in general.

Atmospheric pollution can have natural sources, for example, volcanic eruptions. The gaseous by-products of man-made processes such as energy production, waste incineration, transport, deforestation and agriculture, are the major air pollutants.

Although air is made up of mostly Oxygen and Nitrogen, mankind, through pollution, has increased the levels of many trace gasses, and in some cases, released completely new gasses to the atmosphere.

Air pollution can result in poor air quality, both in cities and in the countryside. Some air pollutants make people sick, causing breathing problems and increasing the likelihood of cancer.

Some air pollutants are harmful to plants, animals, and the ecosystems in which they live. Statues, monuments, and buildings are being corroded by the air pollutants in the form of acid rain. It also damages crops and forests, and makes lakes and streams unsuitable for fish and other plant and animal life.

Air pollution created by man-made resources is also changing the Earth’s atmosphere. It is causing the depletion of the ozone layer and letting in more harmful radiation from the Sun. The greenhouse gasses released into the atmosphere prevents heat from escaping back into space and leads to a rise in global average temperatures. Global warming affects the average sea-level and increases the spread of tropical diseases.

Air pollution occurs when large amounts of gas and tiny particles are released into the air and the ecological balance is disturbed. Each year millions of tons of gasses and particulate matter are emitted into the air.

Primary air pollutants are pollutants, which are directly released into the air. They are called SPM, i.e., Suspended Particulate Matter. For example, smoke, dust, ash, sulfur oxide, nitrogen oxide, and radioactive compounds, etc.

Secondary Pollutants are pollutants, which are formed due to chemical interactions between the atmospheric components and primary pollutants. For example, Smog (i.e. Smoke and fog), ozone, etc.

Major gaseous air pollutants include Carbon Dioxide, Hydrogen Sulfide, Sulfur Dioxide and Nitrogen Oxide, etc.

Natural sources are volcanic eruptions, forest fires, dust storms, etc.

Man-made sources include gasses released from the automobiles, industries, burning of garbage and bricks kilns, etc.

Effects of Air Pollution on Human Health

Air pollution has adverse effects on human health.

Breathing polluted air puts you at higher risk of asthma.

When exposed to ground ozone for 6 to 7 hours, people suffer from respiratory inflammation.

Damages the immune system, endocrine, and reproductive systems.

A high level of air pollution has been associated with higher incidents of heart problems.

The toxic chemicals released into the air are affecting the flora and fauna immensely.

Preventive Measures to Reduce Air Pollution

We can prevent pollution by utilizing raw materials, water energy, and other resources more efficiently. When less harmful substances are substituted for hazardous ones, and when toxic substances are eliminated from the production process, human health can be protected and economic wellbeing can be strengthened.

There are several measures that can be adopted by people to reduce pollution and to save the environment.

Carpooling.

Promotion of public transport.

No smoking zone.

Restricted use of fossil fuels.

Saving energy.

Encouraging organic farming.

The government has put restrictions on the amount of fossil fuels that can be used as well as restrictions on how much carbon dioxide and other pollutants can be emitted. Although the government is attempting to save our environment from these harmful gasses, it is not sufficient. We as a society need to keep the environment clean by controlling the pollution of air.

FAQs on Air Pollution Essay

1. State the Causes of Air Pollution ?

The following are the causes of air pollution.

Vehicular pollution consisting of Carbon Monoxide causes pollution.

Emission of Nitrogen oxide by a large number of supersonic transport airplanes causes deterioration of the Ozone layer and also causes serious damage to the flora and fauna.

The release of Chlorofluorocarbons into the Stratosphere causes depletion of Ozone, which is a serious concern to animals, microscopic, and aquatic organisms.

Burning garbage causes smoke, which pollutes the atmosphere. This smoke contains harmful gases such as Carbon dioxide and Nitrogen oxides.

In India, brick kilns are used for many purposes and coal is used to burn the bricks. They give out huge quantities of Carbon dioxide and particulate matter such as smoke, dust that are very harmful to people working there and the areas surrounding it.

Many cleansing agents release poisonous gases such as Ammonia and Chlorine into the atmosphere.

Radioactive elements emit harmful rays into the air.

Decomposed animals and plants emit Methane and Ammonia gas into the air.

2. What Does Global Warming Mean?

Global warming is the gradual rising average temperature of the Earth's atmosphere due to the concentration of methane in certain toxic gasses such as carbon dioxide. This has a major impact on the world climate. The world is warming. The land and the sea are now warmer than they were at the beginning and temperatures are still rising. This rise in temperature is, in short, global warming. This temperature rise is man-made. The burning of fossil fuels releases greenhouse gasses into the atmosphere which capture solar heat and raise surface and air temperatures.

3. Name the Alternative Modes of Transport. In What Way Does it Help to Reduce Air Pollution?

Public transport could be an alternative mode of transport. Public transport like trains, buses and trams, can relieve traffic congestion and reduce air pollution from road transport. The use of public transport must be encouraged in order to develop a sustainable transport policy.

4. Mention other means of transportation! How can I help reduce air pollution?

Public transportation can be another mode of transportation. Public transport such as trains, buses and trams can reduce traffic congestion and reduce air pollution from road transport. The use of public transport and to develop sustainable transport policies should be encouraged. While one passenger vehicle has the convenience factor, other modes of transportation reduce travel costs, spend less time, reduce stress, improve health, and reduce energy consumption and parking. Other trips for work include walking/cycling, public transport, hybrid travel and transport.

5. What are the effects of pollution?

Excessive air pollution can increase the risk of heart attack, wheezing, coughing and difficulty breathing, as well as irritation of the eyes, nose and throat. Air pollution can also cause heart problems, asthma, and other lung problems. Due to the emission of greenhouse gases, the composition of the air in the air is disturbed. This causes an increase in global temperature. The damaging ozone layer due to air pollution does not prevent harmful ultraviolet rays from the sun, which cause skin and eye problems in individuals. Air pollution has caused a number of respiratory and heart diseases among people. The incidence of lung cancer has increased in recent decades. Children living in contaminated areas are more likely to develop pneumonia and asthma. Many people die every year due to the direct or indirect effects of air pollution. When burning fossil fuels, harmful gases such as nitrogen oxides and sulfur oxides are released into the air. Water droplets combine with these pollutants and become acidic and fall as acid rain, which harms human, animal and plant life.

6. What is the solution to air pollution?

Production of renewable fuels and clean energy. The basic solution to air pollution is to get away from fossil fuels and replace them with other energies such as solar, wind and geothermal. The government limits the amount of fossil fuel that can be used and how much carbon dioxide and other pollutants it can emit. While the government is trying to save our environment from this harmful gas, it is not enough. We as a society need to keep the environment clean by controlling air pollution.

Essay on Air Pollution for Students and Children

500+ words essay on air pollution.

Essay on Air Pollution – Earlier the air we breathe in use to be pure and fresh. But, due to increasing industrialization and concentration of poisonous gases in the environment the air is getting more and more toxic day by day. Also, these gases are the cause of many respiratory and other diseases . Moreover, the rapidly increasing human activities like the burning of fossil fuels, deforestation is the major cause of air pollution.

How Air Gets Polluted?

The fossil fuel , firewood, and other things that we burn produce oxides of carbons which got released into the atmosphere. Earlier there happens to be a large number of trees which can easily filter the air we breathe in. But with the increase in demand for land, the people started cutting down of trees which caused deforestation. That ultimately reduced the filtering capacity of the tree.

Moreover, during the last few decades, the numbers of fossil fuel burning vehicle increased rapidly which increased the number of pollutants in the air .

Causes Of Air Pollution

Its causes include burning of fossil fuel and firewood, smoke released from factories , volcanic eruptions, forest fires, bombardment, asteroids, CFCs (Chlorofluorocarbons), carbon oxides and many more.

Besides, there are some other air pollutants like industrial waste, agricultural waste, power plants, thermal nuclear plants, etc.

Greenhouse Effect

The greenhouse effect is also the cause of air pollution because air pollution produces the gases that greenhouse involves. Besides, it increases the temperature of earth surface so much that the polar caps are melting and most of the UV rays are easily penetrating the surface of the earth.

Moreover, it increases the rate of aging of lungs, decreases lungs function, damage cells in the respiratory system.

Ways To Reduce Air Pollution

Although the level of air pollution has reached a critical point. But, there are still ways by which we can reduce the number of air pollutants from the air.

Reforestation- The quality of air can be improved by planting more and more trees as they clean and filter the air.

Policy for industries- Strict policy for industries related to the filter of gases should be introduced in the countries. So, we can minimize the toxins released from factories.

Use of eco-friendly fuel- We have to adopt the usage of Eco-friendly fuels such as LPG (Liquefied Petroleum Gas), CNG (Compressed Natural Gas), bio-gas, and other eco-friendly fuels. So, we can reduce the amount of harmful toxic gases.

To sum it up, we can say that the air we breathe is getting more and more polluted day by day. The biggest contribution to the increase in air pollution is of fossil fuels which produce nitric and sulphuric oxides. But, humans have taken this problem seriously and are devotedly working to eradicate the problem that they have created.

Above all, many initiatives like plant trees, use of eco-friendly fuel are promoted worldwide.

Stay up to date:, air pollution.

Prevailing wisdom holds that measures to reduce air pollution will also tackle climate change, and vice versa - but this is not always the case.
A new report has identified the most effective interventions for addressing both issues at once.

When we look at air pollution and climate change, we see two dire situations:

1. People, especially in low- and middle-income countries (LMIC), are becoming ill and dying prematurely because of the poor quality of the air they breathe. Air pollution is linked to an estimated 4.2 million premature deaths a year , according to the World Health Organization. When indoor air quality is considered, that number rises by an estimated 2.9 to 4.3 million deaths a year, according to The Lancet Commission .

2. Glacial ice is melting, droughts are becoming more prolonged, extreme weather events are more common, and cities around the world are reporting record-breaking heat, all against a backdrop of predictions from the International Panel on Climate Change of temperature increases between 2.5˚C and 10˚C over the next century.

Air pollution in europe is decreasing but it still has some hotspots, youth can help fight air pollution in africa. here's how, here's a cost-effective way to improve air quality, indoor air pollution: what causes it and how to tackle it.

For years, the prevailing wisdom has argued that the same adverse conditions that propel climate change also are responsible for air pollution, and that by correcting one problem we can also solve the other.

Unfortunately, it's not as simple as that. Some interventions that can massively improve air quality and the health of people in affected communities, such as using lower-sulphur diesel fuel, have little or no impact on climate change. Others produce benefits for the climate but do not significantly impact health. And still other popular and often costly interventions do little to improve air quality or slow the pace of climate change.

With our partners – AirQualityAsia, The Schiller Institute for Integrated Science and Society at Boston College, and with support from the Clean Air Fund – we set out to identify the most successful and practical actions that can improve health by reducing air pollution and impact climate change . Because very little analytical data is available about outcomes for specific interventions, our researchers and consultants went directly to those deeply involved in air pollution projects around the world to learn what had worked, what had not, and why.

The result of these efforts – a new report entitled Air Pollution Interventions: Seeking the Intersection between Climate and Health – is intended to help governments and policy-makers identify and implement the most effective interventions for their communities and particular situations.

reduce-air-pollution-interventions-have-the-greatest-impact

When we talk about adverse health effects from air pollution, our report focuses primarily on particulate matter 2.5 microns and smaller in size (PM2.5), which are largely produced by carbon burning. These microscopic particles, less than one-thirtieth the width of a human air, pass through the lungs and into the bloodstream where they are carried throughout the body to cause damage to respiratory, cardiovascular, and other systems, and according to the Institute for Health Metrics and Evaluation account for more than 85% of air pollution-related mortality .

With regard to climate change, the report mainly looks at activities that increase atmospheric concentrations of carbon dioxide and black carbon.

PM2.5, black carbon and CO2 are largely the byproducts of carbon burning. The three primary sources are:

1. Energy generation from coal and natural gas

2. Public and private transportation of people and goods using diesel or gasoline

3. Open fires, mostly crop burning and forest fires, but also uncontrolled waste incineration

Coal-fired power plants are the granddaddies of air pollution and climate change – and we've known this for some time. Likewise, the single most effective action governments can take to improve air quality and to impact climate change is to phase out the use of coal and other fossil fuels, such as tar and lignite, for power generation.

If you take a big coal-fired power plant in the middle of a city and replace it with renewable energy, that's a huge step to reduce air pollution. Converting coal-fired power plants to natural gas or installing scrubbers reduces PM2.5 emissions – and so benefits health – but the carbon-burning power plants are still producing CO2 and climate-changing emissions. While moving that coal-fired power plant outside the city may be politically popular with millions of city dwellers (less so, perhaps, with people near the new plant), the action is costly and does nothing to benefit health or climate change.

Mortality rates from air pollution around the world

Best ways to reduce air pollution

Other significant interventions that improve both health by reducing PM2.5 and impact climate change by reducing CO2 emissions include:

• Replacing diesel and gasoline-powered vehicles with electric vehicles. Shenzhen, China, for instance, has switched from diesel-powered public transportation to an electric bus fleet with an expected 48% reduction in CO2 emissions and significant reductions in particulate matter.

• Eliminating uncontrolled diesel emissions. Studies have found that reducing vehicle fleet levels from the equivalent of Euro I to Euro IV can reduce fleet emissions by about 80% and moving up to Euro V standards further reduces the remaining emissions by 80%. This is a great step to remove air pollution and CO2 levels.

• Preventing crop burning. Specific technologies and education can improve outcomes for farmers without burning – creating win-win situations. Education and support for agricultural extension programmes in developing countries are key to their success. Poland, for example, has largely phased out the practice of burning the stubble left after the wheat harvest. Government initiatives in Delhi to combat crop burning, a significant source of air pollution, include awareness and capacity building, technological interventions, and subsidies for farmers to purchase straw management machines. Still, the twice-annual traditional crop burning contributes significantly to Delhi's notorious haze.

Our team considered 22 interventions with dozens of supporting case studies with the goal of helping governments and policy-makers determine which interventions may be most practical and beneficial for their particular problems.

Climate change poses an urgent threat demanding decisive action. Communities around the world are already experiencing increased climate impacts, from droughts to floods to rising seas. The World Economic Forum's Global Risks Report continues to rank these environmental threats at the top of the list.

To limit global temperature rise to well below 2°C and as close as possible to 1.5°C above pre-industrial levels, it is essential that businesses, policy-makers, and civil society advance comprehensive near- and long-term climate actions in line with the goals of the Paris Agreement on climate change.

The World Economic Forum's Climate Initiative supports the scaling and acceleration of global climate action through public and private-sector collaboration. The Initiative works across several workstreams to develop and implement inclusive and ambitious solutions.

This includes the Alliance of CEO Climate Leaders, a global network of business leaders from various industries developing cost-effective solutions to transitioning to a low-carbon, climate-resilient economy. CEOs use their position and influence with policy-makers and corporate partners to accelerate the transition and realize the economic benefits of delivering a safer climate.

We know that exposure to PM2.5 makes people more susceptible to respiratory illnesses; preliminary studies and anecdotal reporting early in the COVID-19 pandemic suggest that infection rates initially were higher and illnesses more severe in cities with poorer air quality. We also know that increasingly the citizenry is demanding that its leaders take swift and sure action to combat air pollution, as underscored by a recent survey by the Clean Air Fund of people in the UK, Bulgaria, India, Nigeria and Poland. As The New York Times reports , the survey, which was conducted during the pandemic between 22 May 22 and 2 June, found overwhelming support for stricter air quality regulations and better enforcement of existing rules. In Nigeria and India, for instance, 90% of those surveyed said they wanted improved air quality.

The most important step for municipal and national agencies to reduce air pollution is to raise their level of ambition in achieving their air quality and climate objectives. The overall aim must be an economy where development is uncoupled from resource use and energy provision is de-carbonized. Short-term actions can then be selected and implemented within that framework.

The solutions exist – and with technical support, strategic funding, and public and private initiatives, we can successfully improve public health and combat climate change.

Why clean air?

Climate and air pollution

Action on air pollution is also climate action.

Air pollution is the contamination of air by toxic or polluting particles and gases.

The causes of climate change are often the same as the causes of air pollution: transport, the power sector, industrial emissions and crop burning.

Super pollutants or Short-Lived Climate Pollutants (SCLPs) include methane, black carbon and tropospheric ozone. These contribute to global warming, cause local environmental degradation and harm human health. Climate change can also worsen air quality, with longer summers, wildfire and drought leading to increased levels of ozone and particulate matter.

As the causes of climate change and air pollution are often the same, it’s vital we tackle these challenges together. That means swapping fossil fuel-based power for renewables, greening public transport, cutting industrial emissions and reducing emissions from agriculture.

The health impacts of air pollution are immense, immediate and urgent. Often, concern about dirty air proves to be catalyst for both people and politicians to act on the climate crisis. When we work towards clean air, we accelerate climate action Martina Otto – Climate & Clean Air Coalition

But there are signs of progress. Cleaning our air is one of the most immediate ways to protect the planet. The United Nations Environment Programme (UNEP) has suggested that climate policies that control air pollution emissions could reduce global warming by 0.5˚C and save the lives of 2.4 million people each year.

Joined up action is essential

Many governments and businesses are failing to tackle air pollution as part of their climate action plans, missing opportunities to improve health, deliver wider economic benefits, and support the poorest people and countries. According to the United Nations Framework Convention on Climate Change (UNFCCC), just 17 countries included SLCPs in their national climate action plans in 2021.

Clean air measures can improve air quality, slow global heating, protect ecosystems and deliver a healthier planet for all. Joined up action to tackle dirty air and climate change is essential. Read our recommendations on joined-up action.

Our work on climate and air pollution

We advocate for joined up action at all levels. At the global COP26 climate summit in 2021, we helped launch the first global corporate initiative to tackle air pollution, accelerate climate action and create healthy communities. Read about the Alliance for Clean Air .

Through C40 Cities, we’re working with the world’s biggest cities to support action to meet air quality, climate and public health goals. Learn about C40’s Air Quality programme.

Our work in key geographies supports public engagement on air pollution. We work with policy makers and businesses to set ambitious air quality targets and introduce measures such as Clean Air Zones. Find out about our work in India, EU and UK.

Air pollution is a cause of disease for millions around the world and now more than ever urgent action is required to tackle the burden of its impacts. Doing so will not only improve both life expectancy and quality of life, but will also lead to a more just and sustainable world.

Recently, we announced that we will publish a new series of collections focused on issues related to the Sustainable Development Goals (SDGs). We start this series with a multidisciplinary collection on air pollution. As tackling air pollution is not one of the core SDGs, this may seem like an unusual choice. It is, however, a pressing environmental hazard affecting an ever increasing part of the world’s population. Currently, 91% of the world’s population live in locations where pollution levels exceed WHO guidelines, and in a recent announcement the WHO have further cut the recommended limits. Air pollution kills around 6.7 million people per year mainly through respiratory and cardiovascular diseases 1 , and has significant impacts on mental health. The main pollutants are sourced from fossil fuel combustion for transport, industry, agriculture and cooking stoves and, therefore, air pollution is linked directly with fulfilling many of our basic needs. As the SDGs aim to tackle the issue of how humanity can live sustainably, it is thus no surprise that addressing air pollution is related to the SDGs in many different ways. Promoting specific SDGs will lead to improved air quality as a side-effect, while reducing emissions will also progress a number of SDGs directly.

The high air pollution levels that we live with today is another demonstration of how our unsustainable lifestyles are one of the key challenges that needs to be overcome to create a more just and liveable world, which is the ultimate goal of the SDGs.

Although air pollution is a global issue, exposure is often not distributed equally. Industrial processes related to the production, trade and consumption of goods is a key source of air pollution. Much of this pollution is released in low- and middle-income countries while they manufacture goods that are traded abroad, allowing rich countries to outsource the air pollution and health effects of their consumption. Hence, global implementation of responsible consumption and sustainable production practices—the focus of SDG9 (“Industry, Innovation and Infrastructure”) and SDG12 (“Responsible Consumption and Production”)—will be key to reduce this unequal responsibility and exposure to dangerous environmental conditions.

Inequality in exposure does not only occur at an international level, but also within countries. Systematic and historical forms of discrimination often translate into higher exposure levels and, hence, enhanced health burdens to marginalized groups around the world. This is probably best studied in the US, where people of colour are shown to live under poorer air quality, independent of other factors like income 2 . In a commentary for our collection Viniece Jennings highlights that whilst green infrastructure has the potential to reduce air pollution, unequal access can limit improvements for marginalised communities 3 . While we often think of air pollution as an outdoor issue, much of the exposure to harmful particles actually happens inside houses. Household air pollution is mainly related to cooking, heating or lighting, often through the combustion of solid fuels. This exposure affects women and children disproportionately, especially in the developing world 4 . Consequently, targeting SDG10 (“Reduce inequality within and among countries”) and SDG 7 (“Ensure access to affordable, reliable, sustainable and modern energy for all.”) will be of vital importance to tackle embedded inequalities within and among countries to reduce air pollution exposure.

Air pollution and climate change are closely intertwined as they share the same root cause of human emissions. Even though ambitious climate mitigation policies do not come for free, they will in many cases also lead to improved air quality and lower health costs. The societal costs of air pollution avoided through reduced exposure levels as a result of climate mitigation measures alone are thought to outweigh the initial costs of these policies 5 . Air pollution also physically interacts with the climate system; particles in the atmosphere affect surface temperatures as well as clouds and precipitation. Climate change thus has the potential to “worsen air pollution, even in areas where it has been improving”, as pointed out by Denise Mauzarell in a Q&A for our Clean Air collection 6 . An example of this are the dangerous pollutants released by wildfires that are expected to become ever more frequent and intense in many parts of the world.

Similarly, to climate mitigation, improving air quality depends on strict and ambitious regulatory policies and controls, which must be implemented equitably. In this regard, there are reasons to be optimistic, as strict air quality policies like the Clean Air Act in the US and similar policies in Europe have resulted in reductions in pollution since the 1970s even though levels are still too high and continued efforts are crucial. These efforts show that ambitious policy supported by technological advances like improved filtering and modernization can be successful. These efforts should not only be done at national levels, but also need international collaboration, technology and knowledge transfer in order to acknowledge the shared responsibilities of air pollution. As part of the Clean Air collection we highlight papers Nature Communications has published that look at how policy and technology can be part of the solution to air pollution.

The high air pollution levels that we live with today is another demonstration of how our unsustainable lifestyles are one of the key challenges that needs to be overcome to create a more just and liveable world, which is the ultimate goal of the SDGs. Of course, reducing air pollution on its own will not meet the aims of all the other SDGs. Still, it is an illustrative example of how an interdisciplinary focus on a measurable and technologically approachable issue can help to also achieve other goals. It is in this spirit that our collection brings together research from different disciplines, such as applied scientists, economists, political scientists, health scientists and climate scientists as it is this interdisciplinary collaboration that Nature Communications wants to support will be vital in informing policy and decision makers. We envision that our collection on Clean Air will continue to grow and we welcome submissions across disciplines in this area.

Air Pollution Essay for Students in English: 100, 200 and 500 Words

Air pollution is becoming a serious issue that’s affecting human health, flora and fauna and overall well-being of Earth. As responsible citizens of the world, it’s our duty to take care of anything that’s harming the planet and leave it in better condition for future generations. Here are a few sample essays children can use to write about air pollution and learn about different ways to mitigate this crisis.

Air Pollution Essay for Students in English: 100, 200 and 500 Words

Any physical, chemical, or biological alteration in the air is referred to as air pollution. The atmosphere contains a specific portion of the gas. It is harmful to survival to change the makeup of these gases. “Global warming” is the term used to describe the rise in global temperature caused by this imbalance in gas composition. Hazardous pollutants, whether present naturally or artificially, can modify the environment and have a negative impact on the ecosystem. Ineffective resource management and reckless human activity are harming the environment and therefore it is our responsibility as inhabitants of Earth to take care of it.

Pollution is any activity that tampers with the environment's fundamental characteristics and causes damage. The air we breathe is no longer clean and fresh, it has been contaminated by pollutants. The threat to Earth and its ecosystem is getting worse as a result of the contamination of the air, water, and soil. These pollutants are causing a number of respiratory and cardiovascular diseases—our immune system is getting affected negatively, and children are at a high risk of developing asthma and other breathing problems. There are numerous factors that frequently increase this air pollution. Automobiles, transportation methods, industrialization, expanding cities, etc. are the main causes of air pollution. The contamination of the entire atmosphere is brought on by the release of various toxic gases or dangerous components from such sources.

Air pollution, which has a negative impact on the environment, also has a significant impact on the ozone layer. The primary contributor to pollution is the ever-increasing demands of the human population. Daily human activities pump harmful chemicals into the atmosphere, making it more polluted than ever and accelerating climate change. The flora and fauna are also being severely impacted by the airborne harmful chemical releases. The rising contamination of the Earth's air, water, and soil—the essential life support systems of the planet—poses a major threat to the planet and its environment.

One of today's top environmental concerns is air pollution. There are numerous factors that frequently increase this air pollution. Toxic gases, particulates, paint, and batteries containing lead are released throughout the industrialization process. The ozone layer is also being destroyed and the world is being exposed to dangerous solar rays as a result of all the contaminants in touch with the atmosphere.

Ozone is a contaminant that exists at the ground level and can be harmful to human health. But the same ozone creates a layer of defence in the stratosphere. The "good" ozone, however, is being destroyed by ozone-depleting substances—such as hydrochlorofluorocarbons, and chlorofluorocarbons. These chemicals were once used in coolants, foaming agents, insecticides, solvents, and fire extinguishers and occasionally still are.

Primary and secondary pollutants are the two categories that have emerged as a result of the growing number of air pollutants. Primary pollutants, which include smoke, ash, dust, fumes, mist, spray, inorganic gases, carbon dioxide, carbon monoxide, and radioactive substances, have a direct negative impact on fresh air. Secondary pollutants are those that interact chemically with primary pollutants, as well as other elements in the atmosphere, such as sulphate trioxide, ozone, hydrocarbons, and nitrogen dioxide.

Causes of Air Pollution

The disposal of solid wastes that release methane gas and the breakdown of trash landfills are major sources of air pollution. This problem has become a severe environmental and health issue as a result of the population's rapid development, industrialisation, and greater use of cars, planes, and other transportation.

Common Effects of Air Pollution

Pollutants in the air we breathe every minute enter our bloodstream and travel to our lungs and entire body, producing a plethora of health issues. Animals can have health issues similar to people if they are exposed to air toxics in high enough quantities over an extended period of time. Air toxics also play a role in animal sickness, infertility, and birth abnormalities. Therefore, both directly and indirectly, pollution of the environment harms both plants, animals, and people.

What Can We Do

Using public transportation is a surefire short method to reduce air pollution because it uses less gas and electricity, even carpools help with the situation. A permanent, non-polluting, and extremely secure source of energy is the sun or solar power. Solar panels, which are special in design and simple to install, are also a technical benefit to society and the planet. They take in solar energy and store it to power various equipment and electronics. Another step you can take on this path is to plant more trees and live a simplistic life. Minimalist living is not only a trendy millennial lifestyle, but it also has significant societal and environmental benefits.

Air pollution may reach one million tonnes annually in the next decades if environmental protection measures are not taken seriously and effectively enforced. We need to drastically alter our everyday routines if we want to lower the level of air pollution. By making better use of raw materials, water energy, and other resources, we can reduce pollution. Human health can be safeguarded and economic wellbeing can be increased when less harmful compounds are exchanged for hazardous ones.

Essay on Air Pollution – Sample 1 (200 Words)

Air pollution is a serious issue and a cause for major concern in today’s world. A report published in 2014 by the World Health Organisation states that 4.21 million individuals died prematurely in 2012 as a result of air pollution. Air pollution existed much before humans, in the form of volcanic eruptions and forest fires. However, it became much more prevalent after the Industrial Revolution.

Rapid industrial growth, unregulated emissions and a host of other issues significantly contributed to the rise in air pollution. In some cases, the severity of air pollution reached an extent where government intervention was necessary. The Great Smog of London, 1952, was an extreme case of air pollution where visibility was severely hampered. It also caused a host of illnesses and the consequent deaths of countless civilians. In November 2017, the levels of air pollution in Delhi were ten times above the safe limits. For reference, the healthy air quality index is between 0 to 50, but during that particular time period, the air quality index hit 500+. This event is now called the Great Smog of Delhi.

An air quality index of 500 and above indicates that the air is heavily polluted and will cause irreversible lung damage and a host of other illnesses to everyone who is exposed to it. Therefore, to avoid such situations in the future, relevant actions must be implemented.

Essay on Air Pollution – Sample 2 (500 Words)

Air pollution may seem like the result of anthropological activities, however, it has been around even before humans evolved. Places which are naturally arid and have minimal vegetation are prone to dust storms. When this particulate matter is added to the air, it can cause health issues in animals exposed to the dust storms.

Furthermore, active volcanoes pump extremely large amounts of toxic plumes and particulate matter into the atmosphere. Wildfires also pump large amounts of carbon monoxide into the atmosphere and hamper photosynthesis for plants. Even animals, especially ruminants such as cows contribute to global warming by producing large quantities of methane, a greenhouse gas.

However, air pollution was never a major concern until the industrial revolution. Industries grew rapidly, untreated emissions were pumped into the atmosphere, and the rise of automobiles significantly contributed to air pollution. Such activities continued without any restrictions until they started to cause a wide range of repercussions.

In humans, air polluted with contaminants can cause a wide array of illnesses ranging from asthma and bronchitis the various forms of cancer. Air pollution is not only present outdoors; interior air pollution is also a great concern. Recent research has actually found credible evidence that room fresheners have the many compounds within them, some of which are classified carcinogens. This means some of those compounds present in the aerosol has the potential to cause some forms of cancer. Other sources of air pollution can include gases such as carbon monoxide and radon.

Radon, in particular, is quite alarming. It is an odourless, colourless gas that occurs naturally. It is found in the soil as Uranium, which breaks down and eventually turns into radon gas. Radon has limited repercussions on health if exposed to low concentrations, however, when this gas gets trapped indoor, the higher levels of concentration can have wreak havoc or ultimately be lethal. Radon is also reported to be released from building materials such as granite. Exposure to radon causes no immediate health effects, but long term exposure has the potential to cause lung cancer.

Air pollution not only affects the lungs but the central nervous system too. It has been linked to a lot of diseases such as schizophrenia and autism. A study also implied that it can cause short-term memory losses or distortion of memory.

Historically, air pollution has caused many crises with the worst ever being the Bhopal Disaster in 1984. Fatalities were estimated at 3,800, with at least 600,000 injured. Next in severity was the Great Smog of 1952 which formed over London, killing an estimated 4,000 civilians over the course of four days.

Though measures have been taken to reduce the effects of air pollution, a lot of irreversible damage has been done. For instance, the effects of global warming have drastically increased; this is very apparent with the rise in sea levels and melting glaciers. If the ice caps continue to melt, then we will have to face drastic repercussions. Scientists have proposed a hypothetical scenario where the greenhouse effect becomes “uncontrolled.” Here, greenhouse gases build up and temperatures continue to rise steeply. Oceans will start to evaporate, adding more water vapour into the earth’s atmosphere. This intensifies the effect, reaching a point where temperatures are sufficiently high for rocks start sublimating. Though this scenario is hypothetical, some speculate that this phenomenon already occurred on Venus. The supporters of this theory back this up by claiming Venus has an atmosphere composed primarily of carbon dioxide. The theory also explains why Venus has an extremely high surface temperature of 462 degrees Celcius; which is in fact, the hottest planet in the solar system.

Hence, we need to reduce our impact on the planet and make a conscious effort to reduce air pollution. Explore more essay topics or other fascinating concepts by registering at BYJU’S

What is air pollution?

What causes air pollution, effects of air pollution, air pollution in the united states, air pollution and environmental justice, controlling air pollution, how to help reduce air pollution, how to protect your health.

Air pollution refers to the release of pollutants into the air—pollutants that are detrimental to human health and the planet as a whole. According to the World Health Organization (WHO) , each year, indoor and outdoor air pollution is responsible for nearly seven million deaths around the globe. Ninety-nine percent of human beings currently breathe air that exceeds the WHO’s guideline limits for pollutants, with those living in low- and middle-income countries suffering the most. In the United States, the Clean Air Act , established in 1970, authorizes the U.S. Environmental Protection Agency (EPA) to safeguard public health by regulating the emissions of these harmful air pollutants.

“Most air pollution comes from energy use and production,” says John Walke , director of the Clean Air team at NRDC. Driving a car on gasoline, heating a home with oil, running a power plant on fracked gas : In each case, a fossil fuel is burned and harmful chemicals and gases are released into the air.

“We’ve made progress over the last 50 years in improving air quality in the United States, thanks to the Clean Air Act. But climate change will make it harder in the future to meet pollution standards, which are designed to protect health ,” says Walke.

Air pollution is now the world’s fourth-largest risk factor for early death. According to the 2020 State of Global Air report —which summarizes the latest scientific understanding of air pollution around the world—4.5 million deaths were linked to outdoor air pollution exposures in 2019, and another 2.2 million deaths were caused by indoor air pollution. The world’s most populous countries, China and India, continue to bear the highest burdens of disease.

“Despite improvements in reducing global average mortality rates from air pollution, this report also serves as a sobering reminder that the climate crisis threatens to worsen air pollution problems significantly,” explains Vijay Limaye , senior scientist in NRDC’s Science Office. Smog, for instance, is intensified by increased heat, forming when the weather is warmer and there’s more ultraviolet radiation. In addition, climate change increases the production of allergenic air pollutants, including mold (thanks to damp conditions caused by extreme weather and increased flooding) and pollen (due to a longer pollen season). “Climate change–fueled droughts and dry conditions are also setting the stage for dangerous wildfires,” adds Limaye. “ Wildfire smoke can linger for days and pollute the air with particulate matter hundreds of miles downwind.”

The effects of air pollution on the human body vary, depending on the type of pollutant, the length and level of exposure, and other factors, including a person’s individual health risks and the cumulative impacts of multiple pollutants or stressors.

Smog and soot

These are the two most prevalent types of air pollution. Smog (sometimes referred to as ground-level ozone) occurs when emissions from combusting fossil fuels react with sunlight. Soot—a type of particulate matter —is made up of tiny particles of chemicals, soil, smoke, dust, or allergens that are carried in the air. The sources of smog and soot are similar. “Both come from cars and trucks, factories, power plants, incinerators, engines, generally anything that combusts fossil fuels such as coal, gasoline, or natural gas,” Walke says.

Smog can irritate the eyes and throat and also damage the lungs, especially those of children, senior citizens, and people who work or exercise outdoors. It’s even worse for people who have asthma or allergies; these extra pollutants can intensify their symptoms and trigger asthma attacks. The tiniest airborne particles in soot are especially dangerous because they can penetrate the lungs and bloodstream and worsen bronchitis, lead to heart attacks, and even hasten death. In 2020, a report from Harvard’s T.H. Chan School of Public Health showed that COVID-19 mortality rates were higher in areas with more particulate matter pollution than in areas with even slightly less, showing a correlation between the virus’s deadliness and long-term exposure to air pollution.

These findings also illuminate an important environmental justice issue . Because highways and polluting facilities have historically been sited in or next to low-income neighborhoods and communities of color, the negative effects of this pollution have been disproportionately experienced by the people who live in these communities.

Hazardous air pollutants

A number of air pollutants pose severe health risks and can sometimes be fatal, even in small amounts. Almost 200 of them are regulated by law; some of the most common are mercury, lead , dioxins, and benzene. “These are also most often emitted during gas or coal combustion, incineration, or—in the case of benzene—found in gasoline,” Walke says. Benzene, classified as a carcinogen by the EPA, can cause eye, skin, and lung irritation in the short term and blood disorders in the long term. Dioxins, more typically found in food but also present in small amounts in the air, is another carcinogen that can affect the liver in the short term and harm the immune, nervous, and endocrine systems, as well as reproductive functions. Mercury attacks the central nervous system. In large amounts, lead can damage children’s brains and kidneys, and even minimal exposure can affect children’s IQ and ability to learn.

Another category of toxic compounds, polycyclic aromatic hydrocarbons (PAHs), are by-products of traffic exhaust and wildfire smoke. In large amounts, they have been linked to eye and lung irritation, blood and liver issues, and even cancer. In one study , the children of mothers exposed to PAHs during pregnancy showed slower brain-processing speeds and more pronounced symptoms of ADHD.

Greenhouse gases

While these climate pollutants don’t have the direct or immediate impacts on the human body associated with other air pollutants, like smog or hazardous chemicals, they are still harmful to our health. By trapping the earth’s heat in the atmosphere, greenhouse gases lead to warmer temperatures, which in turn lead to the hallmarks of climate change: rising sea levels, more extreme weather, heat-related deaths, and the increased transmission of infectious diseases. In 2021, carbon dioxide accounted for roughly 79 percent of the country’s total greenhouse gas emissions, and methane made up more than 11 percent. “Carbon dioxide comes from combusting fossil fuels, and methane comes from natural and industrial sources, including large amounts that are released during oil and gas drilling,” Walke says. “We emit far larger amounts of carbon dioxide, but methane is significantly more potent, so it’s also very destructive.”

Another class of greenhouse gases, hydrofluorocarbons (HFCs) , are thousands of times more powerful than carbon dioxide in their ability to trap heat. In October 2016, more than 140 countries signed the Kigali Agreement to reduce the use of these chemicals—which are found in air conditioners and refrigerators—and develop greener alternatives over time. (The United States officially signed onto the Kigali Agreement in 2022.)

Pollen and mold

Mold and allergens from trees, weeds, and grass are also carried in the air, are exacerbated by climate change, and can be hazardous to health. Though they aren’t regulated, they can be considered a form of air pollution. “When homes, schools, or businesses get water damage, mold can grow and produce allergenic airborne pollutants,” says Kim Knowlton, professor of environmental health sciences at Columbia University and a former NRDC scientist. “ Mold exposure can precipitate asthma attacks or an allergic response, and some molds can even produce toxins that would be dangerous for anyone to inhale.”

Pollen allergies are worsening because of climate change . “Lab and field studies are showing that pollen-producing plants—especially ragweed—grow larger and produce more pollen when you increase the amount of carbon dioxide that they grow in,” Knowlton says. “Climate change also extends the pollen production season, and some studies are beginning to suggest that ragweed pollen itself might be becoming a more potent allergen.” If so, more people will suffer runny noses, fevers, itchy eyes, and other symptoms. “And for people with allergies and asthma, pollen peaks can precipitate asthma attacks, which are far more serious and can be life-threatening.”

More than one in three U.S. residents—120 million people—live in counties with unhealthy levels of air pollution, according to the 2023 State of the Air report by the American Lung Association (ALA). Since the annual report was first published, in 2000, its findings have shown how the Clean Air Act has been able to reduce harmful emissions from transportation, power plants, and manufacturing.

Recent findings, however, reflect how climate change–fueled wildfires and extreme heat are adding to the challenges of protecting public health. The latest report—which focuses on ozone, year-round particle pollution, and short-term particle pollution—also finds that people of color are 61 percent more likely than white people to live in a county with a failing grade in at least one of those categories, and three times more likely to live in a county that fails in all three.

In rankings for each of the three pollution categories covered by the ALA report, California cities occupy the top three slots (i.e., were highest in pollution), despite progress that the Golden State has made in reducing air pollution emissions in the past half century. At the other end of the spectrum, these cities consistently rank among the country’s best for air quality: Burlington, Vermont; Honolulu; and Wilmington, North Carolina.

No one wants to live next door to an incinerator, oil refinery, port, toxic waste dump, or other polluting site. Yet millions of people around the world do, and this puts them at a much higher risk for respiratory disease, cardiovascular disease, neurological damage, cancer, and death. In the United States, people of color are 1.5 times more likely than whites to live in areas with poor air quality, according to the ALA.

Historically, racist zoning policies and discriminatory lending practices known as redlining have combined to keep polluting industries and car-choked highways away from white neighborhoods and have turned communities of color—especially low-income and working-class communities of color—into sacrifice zones, where residents are forced to breathe dirty air and suffer the many health problems associated with it. In addition to the increased health risks that come from living in such places, the polluted air can economically harm residents in the form of missed workdays and higher medical costs.

Environmental racism isn't limited to cities and industrial areas. Outdoor laborers, including the estimated three million migrant and seasonal farmworkers in the United States, are among the most vulnerable to air pollution—and they’re also among the least equipped, politically, to pressure employers and lawmakers to affirm their right to breathe clean air.

Recently, cumulative impact mapping , which uses data on environmental conditions and demographics, has been able to show how some communities are overburdened with layers of issues, like high levels of poverty, unemployment, and pollution. Tools like the Environmental Justice Screening Method and the EPA’s EJScreen provide evidence of what many environmental justice communities have been explaining for decades: that we need land use and public health reforms to ensure that vulnerable areas are not overburdened and that the people who need resources the most are receiving them.

In the United States, the Clean Air Act has been a crucial tool for reducing air pollution since its passage in 1970, although fossil fuel interests aided by industry-friendly lawmakers have frequently attempted to weaken its many protections. Ensuring that this bedrock environmental law remains intact and properly enforced will always be key to maintaining and improving our air quality.

But the best, most effective way to control air pollution is to speed up our transition to cleaner fuels and industrial processes. By switching over to renewable energy sources (such as wind and solar power), maximizing fuel efficiency in our vehicles, and replacing more and more of our gasoline-powered cars and trucks with electric versions, we'll be limiting air pollution at its source while also curbing the global warming that heightens so many of its worst health impacts.

And what about the economic costs of controlling air pollution? According to a report on the Clean Air Act commissioned by NRDC, the annual benefits of cleaner air are up to 32 times greater than the cost of clean air regulations. Those benefits include up to 370,000 avoided premature deaths, 189,000 fewer hospital admissions for cardiac and respiratory illnesses, and net economic benefits of up to $3.8 trillion for the U.S. economy every year.

“The less gasoline we burn, the better we’re doing to reduce air pollution and the harmful effects of climate change,” Walke explains. “Make good choices about transportation. When you can, ride a bike, walk, or take public transportation. For driving, choose a car that gets better miles per gallon of gas or buy an electric car .” You can also investigate your power provider options—you may be able to request that your electricity be supplied by wind or solar. Buying your food locally cuts down on the fossil fuels burned in trucking or flying food in from across the world. And most important: “Support leaders who push for clean air and water and responsible steps on climate change,” Walke says.

“When you see in the news or hear on the weather report that pollution levels are high, it may be useful to limit the time when children go outside or you go for a jog,” Walke says. Generally, ozone levels tend to be lower in the morning.
If you exercise outside, stay as far as you can from heavily trafficked roads. Then shower and wash your clothes to remove fine particles.
The air may look clear, but that doesn’t mean it’s pollution free. Utilize tools like the EPA’s air pollution monitor, AirNow , to get the latest conditions. If the air quality is bad, stay inside with the windows closed.
If you live or work in an area that’s prone to wildfires, stay away from the harmful smoke as much as you’re able. Consider keeping a small stock of masks to wear when conditions are poor. The most ideal masks for smoke particles will be labelled “NIOSH” (which stands for National Institute for Occupational Safety and Health) and have either “N95” or “P100” printed on it.
If you’re using an air conditioner while outdoor pollution conditions are bad, use the recirculating setting to limit the amount of polluted air that gets inside.

Loading ...

Air pollution consists of chemicals or particles in the air that can harm the health of humans, animals, and plants. It also damages buildings. Pollutants in the air take many forms. They can be gases , solid particles, or liquid droplets. Sources of Air Pollution Pollution enters the Earth's atmosphere in many different ways. Most air pollution is created by people, taking the form of emissions from factories, cars, planes, or aerosol cans . Second-hand cigarette smoke is also considered air pollution. These man-made sources of pollution are called anthropogenic sources . Some types of air pollution, such as smoke from wildfires or ash from volcanoes , occur naturally. These are called natural sources . Air pollution is most common in large cities where emissions from many different sources are concentrated . Sometimes, mountains or tall buildings prevent air pollution from spreading out. This air pollution often appears as a cloud making the air murky. It is called smog . The word "smog" comes from combining the words "smoke" and " fog ." Large cities in poor and developing nations tend to have more air pollution than cities in developed nations. According to the World Health Organization (WHO) , some of the worlds most polluted cities are Karachi, Pakistan; New Delhi, India; Beijing, China; Lima, Peru; and Cairo, Egypt. However, many developed nations also have air pollution problems. Los Angeles, California, is nicknamed Smog City. Indoor Air Pollution Air pollution is usually thought of as smoke from large factories or exhaust from vehicles. But there are many types of indoor air pollution as well. Heating a house by burning substances such as kerosene , wood, and coal can contaminate the air inside the house. Ash and smoke make breathing difficult, and they can stick to walls, food, and clothing. Naturally-occurring radon gas, a cancer -causing material, can also build up in homes. Radon is released through the surface of the Earth. Inexpensive systems installed by professionals can reduce radon levels. Some construction materials, including insulation , are also dangerous to people's health. In addition, ventilation , or air movement, in homes and rooms can lead to the spread of toxic mold . A single colony of mold may exist in a damp, cool place in a house, such as between walls. The mold's spores enter the air and spread throughout the house. People can become sick from breathing in the spores. Effects On Humans People experience a wide range of health effects from being exposed to air pollution. Effects can be broken down into short-term effects and long-term effects . Short-term effects, which are temporary , include illnesses such as pneumonia or bronchitis . They also include discomfort such as irritation to the nose, throat, eyes, or skin. Air pollution can also cause headaches, dizziness, and nausea . Bad smells made by factories, garbage , or sewer systems are considered air pollution, too. These odors are less serious but still unpleasant . Long-term effects of air pollution can last for years or for an entire lifetime. They can even lead to a person's death. Long-term health effects from air pollution include heart disease , lung cancer, and respiratory diseases such as emphysema . Air pollution can also cause long-term damage to people's nerves , brain, kidneys , liver , and other organs. Some scientists suspect air pollutants cause birth defects . Nearly 2.5 million people die worldwide each year from the effects of outdoor or indoor air pollution. People react differently to different types of air pollution. Young children and older adults, whose immune systems tend to be weaker, are often more sensitive to pollution. Conditions such as asthma , heart disease, and lung disease can be made worse by exposure to air pollution. The length of exposure and amount and type of pollutants are also factors. Effects On The Environment Like people, animals, and plants, entire ecosystems can suffer effects from air pollution. Haze , like smog, is a visible type of air pollution that obscures shapes and colors. Hazy air pollution can even muffle sounds. Air pollution particles eventually fall back to Earth. Air pollution can directly contaminate the surface of bodies of water and soil . This can kill crops or reduce their yield . It can kill young trees and other plants. Sulfur dioxide and nitrogen oxide particles in the air, can create acid rain when they mix with water and oxygen in the atmosphere. These air pollutants come mostly from coal-fired power plants and motor vehicles . When acid rain falls to Earth, it damages plants by changing soil composition ; degrades water quality in rivers, lakes and streams; damages crops; and can cause buildings and monuments to decay . Like humans, animals can suffer health effects from exposure to air pollution. Birth defects, diseases, and lower reproductive rates have all been attributed to air pollution. Global Warming Global warming is an environmental phenomenon caused by natural and anthropogenic air pollution. It refers to rising air and ocean temperatures around the world. This temperature rise is at least partially caused by an increase in the amount of greenhouse gases in the atmosphere. Greenhouse gases trap heat energy in the Earths atmosphere. (Usually, more of Earths heat escapes into space.) Carbon dioxide is a greenhouse gas that has had the biggest effect on global warming. Carbon dioxide is emitted into the atmosphere by burning fossil fuels (coal, gasoline , and natural gas ). Humans have come to rely on fossil fuels to power cars and planes, heat homes, and run factories. Doing these things pollutes the air with carbon dioxide. Other greenhouse gases emitted by natural and artificial sources also include methane , nitrous oxide , and fluorinated gases. Methane is a major emission from coal plants and agricultural processes. Nitrous oxide is a common emission from industrial factories, agriculture, and the burning of fossil fuels in cars. Fluorinated gases, such as hydrofluorocarbons , are emitted by industry. Fluorinated gases are often used instead of gases such as chlorofluorocarbons (CFCs). CFCs have been outlawed in many places because they deplete the ozone layer . Worldwide, many countries have taken steps to reduce or limit greenhouse gas emissions to combat global warming. The Kyoto Protocol , first adopted in Kyoto, Japan, in 1997, is an agreement between 183 countries that they will work to reduce their carbon dioxide emissions. The United States has not signed that treaty . Regulation In addition to the international Kyoto Protocol, most developed nations have adopted laws to regulate emissions and reduce air pollution. In the United States, debate is under way about a system called cap and trade to limit emissions. This system would cap, or place a limit, on the amount of pollution a company is allowed. Companies that exceeded their cap would have to pay. Companies that polluted less than their cap could trade or sell their remaining pollution allowance to other companies. Cap and trade would essentially pay companies to limit pollution. In 2006 the World Health Organization issued new Air Quality Guidelines. The WHOs guidelines are tougher than most individual countries existing guidelines. The WHO guidelines aim to reduce air pollution-related deaths by 15 percent a year. Reduction Anybody can take steps to reduce air pollution. Millions of people every day make simple changes in their lives to do this. Taking public transportation instead of driving a car, or riding a bike instead of traveling in carbon dioxide-emitting vehicles are a couple of ways to reduce air pollution. Avoiding aerosol cans, recycling yard trimmings instead of burning them, and not smoking cigarettes are others.

Downwinders The United States conducted tests of nuclear weapons at the Nevada Test Site in southern Nevada in the 1950s. These tests sent invisible radioactive particles into the atmosphere. These air pollution particles traveled with wind currents, eventually falling to Earth, sometimes hundreds of miles away in states including Idaho, Utah, Arizona, and Washington. These areas were considered to be "downwind" from the Nevada Test Site. Decades later, people living in those downwind areascalled "downwinders"began developing cancer at above-normal rates. In 1990, the U.S. government passed the Radiation Exposure Compensation Act. This law entitles some downwinders to payments of $50,000.

Greenhouse Gases There are five major greenhouse gases in Earth's atmosphere.

water vapor
carbon dioxide
nitrous oxide

London Smog What has come to be known as the London Smog of 1952, or the Great Smog of 1952, was a four-day incident that sickened 100,000 people and caused as many as 12,000 deaths. Very cold weather in December 1952 led residents of London, England, to burn more coal to keep warm. Smoke and other pollutants became trapped by a thick fog that settled over the city. The polluted fog became so thick that people could only see a few meters in front of them.

500+ Words Essay on Air Pollution

Air pollution refers to the unwanted and harmful substances in the air we breathe. These substances are known as pollutants. Air pollution can be caused by natural sources or human activities and can have serious health, environmental, and economic impacts. In recent years, air pollution has become a popular debate topic due to the decreasing quality of air. The atmosphere of Earth comprises 78% of Nitrogen, 21% of Oxygen, and 0.93% of Argon.

The causes of air pollution are both natural and man-made. Natural sources of air pollution are volcanic eruptions, wildfires, and dust storms. However, human activities like transportation, industrial activities, agricultural practices, waste management, etc. have more serious and long-term impacts on the air we breathe. An essay on air pollution is a popular academic writing topic assigned to students. To help students with their essays on air pollution, we have listed some samples in 100, 200, and 300 words. These samples will discuss the causes, consequences, and steps to reduce air pollution.

Air pollution poses serious environmental and health risks. It is caused by the release of harmful particles and gases in the air. This deteriorates the quality of air we breathe and poses a serious threat to the existence of all living beings on Earth. Human activities, for a long, have been the majority responsible for air pollution. These include vehicle emissions, industrial activities, and agricultural practices that release harmful pollutants into the air.

Prolonged exposure to air pollution can lead to respiratory diseases, cardiovascular problems, and even premature death. Not only this, air pollution also poses a serious threat to the environment, leading to climate change. Environmentalists, international organizations, governments, and even private organizations are collectively working to reduce air pollution. They have implemented strict, cleaner technologies, and public awareness campaigns. These concerted efforts can help improve the air quality and create a healthy environment.

With rising environmental and health concerns, air pollution has become a popular debate topic. Air pollution is caused by natural and human activities, which release harmful substances, chemicals, and gases into the air we breathe. Our once-healthy environment has become a gas chamber, causing an existential threat to every species on Earth.

Since the advent of 18th-century Industrialisation, the emission of harmful gases like hydrogen chloride, benzene, and toluene has significantly increased. According to a report by the U.S. Environmental Protection Agency, a total of 188 pollutants have been classified as hazardous.

Human activities like burning fossil fuels for energy production, vehicular emission, construction and industrial releases are the major causes of air pollution. There are natural sources also which are responsible for air pollution but their impact is limited to their respective regions. For example, during a volcanic eruption, harmful gases like water vapor (H2O), carbon dioxide (CO2), and sulfur dioxide (SO2), are released into the atmosphere. However, such natural activities do not pose a global threat.

Tackling air pollution requires global cooperation and environmentally friendly approaches. One such method is relying on renewable energy sources, rather than exhausting limited natural resources, fossil fuels. World Health Organisation, along with global governments is taking steps to switch to affordable clean household energy solutions for cooking, heating and lighting.

Air pollution is a global concern. Therefore, it requires a collective approach from all countries and their respective governments. Careful implementation of environmentally friendly and sustained approaches will surely help create an air pollution-free environment.

World Health Organisation in its 2019 report stated that 99% of the world’s population was living in places where the WHO air quality guidelines levels were not met. Air pollution is known as the releaseof unwanted harmful substances and chemicals in the air. This damages the qualities of air we breath, affecting health and detoriates the environment quality. Air pollution is responsible for millions of premature deaths every year.

Causes of Air Pollution

Air pollution is caused by both natural and man-made activities. Nature causes of air pollution are volcanic erruptions, dust storms, and wildfires. During a volcanic eruption, harm gases and chemicals like water vapor (H2O), carbon dioxide (CO2), and sulfur dioxide (SO2) are released. Also, a small amounts of hydrogen sulfide, carbon monoxide, hydrogen chloride are also released. However, natural causes of air pollution are limited to there regions and do not poses long term environmental threats.

Human activities causes are the major factors causing air pollution. Human activities like industrialisation, vehicular emission, combustion, energy production, construction, agricultural activities and waste management are major factors of air pollution. Human activities releases pollutants like Carbon Monoxide, (CO), Nitrogen Dioxide (NO2), Carbon Dioxide (CO2) and methane causes air pollution.

In metropolitan cities like New Delhi, Mumbai, Beijing, Tokyo, etc. vehicular emission and construction are major causes of air pollution. Construction sites generate dust and emissions from equipment, contributing to local air pollution.

Consequences of Air Pollution

Air pollution has harmful consequences on human health, the environment, and the economy.
Air pollution contributes to a wide range of health problems, including respiratory diseases, cardiovascular diseases, lung cancer, and respiratory infections. Some of these diseases are asthma, chronic obstructive pulmonary disease.
Long-term exposure to air pollution can lead to decreased lung function, aggravation of existing health conditions, and premature death, particularly among vulnerable populations such as children, the elderly, and individuals with pre-existing health conditions.
Our ecosystem is the first victim of air pollution. Pollutants deposited onto soil and water bodies harm plants, animals, and aquatic life.
Acid rain, caused by sulfur dioxide and nitrogen oxides reacting with water vapor in the atmosphere, damages forests, soils, and freshwater ecosystem
Pollutants like carbon dioxide, methane, and black carbon are all also greenhouse gases, contributing to climate change.
The rate at which these pollutants are released in the atmosphere can lead to global warming, rising temperatures, altered weather patterns, and more frequent and intense extreme weather events.
Air pollution also affects our economy. Investments in air pollution control measures and environmental cleanup efforts entail financial expenditures for governments, businesses, and individuals.

Steps to Reduce Air Pollution

Policies and investments in air pollution control measures are necessary to reduce the content of pollutants.
Switching to environmental friendly activities can significantly help reduce air pollution. Excessive use of natural resources not only depletes them but puts a stain on the environment.
Relying on solar energy, hydro energy and wind energy can reduce them burden on coal for electricity and power generation.
On individual level, we can practice carpooling, use public transportation, cycling, walking, or electric vehicles whenever possible.
we can avoid unnecessary idling to maintain proper tire pressure, and combine errands to minimize trips.
Build a habit of turning lights and electronics off when not in use. Invest in energy-efficient appliances and adjust thermostats for optimal temperature control.
Minimize waste generation and opt for reusable products whenever possible.
Recycling reduces the need for raw materials and lowers energy consumption during production of new goods.

Air Pollution: Current and Future Challenges

Despite dramatic progress cleaning the air since 1970, air pollution in the United States continues to harm people’s health and the environment. Under the Clean Air Act, EPA continues to work with state, local and tribal governments, other federal agencies, and stakeholders to reduce air pollution and the damage that it causes.

Learn about more about air pollution, air pollution programs, and what you can do.

Outdoor air pollution challenges facing the United States today include:

Meeting health-based standards for common air pollutants
Limiting climate change
Reducing risks from toxic air pollutants
Protecting the stratospheric ozone layer against degradation

Indoor air pollution, which arises from a variety of causes, also can cause health problems. For more information on indoor air pollution, which is not regulated under the Clean Air Act, see EPA’s indoor air web site .

Air Pollution Challenges: Common Pollutants

Great progress has been made in achieving national air quality standards, which EPA originally established in 1971 and updates periodically based on the latest science. One sign of this progress is that visible air pollution is less frequent and widespread than it was in the 1970s.

However, air pollution can be harmful even when it is not visible. Newer scientific studies have shown that some pollutants can harm public health and welfare even at very low levels. EPA in recent years revised standards for five of the six common pollutants subject to national air quality standards. EPA made the standards more protective because new, peer-reviewed scientific studies showed that existing standards were not adequate to protect public health and the environment.

Status of common pollutant problems in brief

Today, pollution levels in many areas of the United States exceed national air quality standards for at least one of the six common pollutants:

Although levels of particle pollution and ground-level ozone pollution are substantially lower than in the past, levels are unhealthy in numerous areas of the country. Both pollutants are the result of emissions from diverse sources, and travel long distances and across state lines. An extensive body of scientific evidence shows that long- and short-term exposures to fine particle pollution, also known as fine particulate matter (PM 2.5 ), can cause premature death and harmful effects on the cardiovascular system, including increased hospital admissions and emergency department visits for heart attacks and strokes. Scientific evidence also links PM to harmful respiratory effects, including asthma attacks. Ozone can increase the frequency of asthma attacks, cause shortness of breath, aggravate lung diseases, and cause permanent damage to lungs through long-term exposure. Elevated ozone levels are linked to increases in hospitalizations, emergency room visits and premature death. Both pollutants cause environmental damage, and fine particles impair visibility. Fine particles can be emitted directly or formed from gaseous emissions including sulfur dioxide or nitrogen oxides. Ozone, a colorless gas, is created when emissions of nitrogen oxides and volatile organic compounds react.
For unhealthy peak levels of sulfur dioxide and nitrogen dioxide , EPA is working with states and others on ways to determine where and how often unhealthy peaks occur. Both pollutants cause multiple adverse respiratory effects including increased asthma symptoms, and are associated with increased emergency department visits and hospital admissions for respiratory illness. Both pollutants cause environmental damage, and are byproducts of fossil fuel combustion.
Airborne lead pollution, a nationwide health concern before EPA phased out lead in motor vehicle gasoline under Clean Air Act authority, now meets national air quality standards except in areas near certain large lead-emitting industrial facilities. Lead is associated with neurological effects in children, such as behavioral problems, learning deficits and lowered IQ, and high blood pressure and heart disease in adults.
The entire nation meets the carbon monoxide air quality standards, largely because of emissions standards for new motor vehicles under the Clean Air Act.

In Brief: How EPA is working with states and tribes to limit common air pollutants

EPA's air research provides the critical science to develop and implement outdoor air regulations under the Clean Air Act and puts new tools and information in the hands of air quality managers and regulators to protect the air we breathe.
To reflect new scientific studies, EPA revised the national air quality standards for fine particles (2006, 2012), ground-level ozone (2008, 2015), sulfur dioxide (2010), nitrogen dioxide (2010), and lead (2008). After the scientific review, EPA decided to retain the existing standards for carbon monoxide. EPA strengthened the air quality standards for ground-level ozone in October 2015 based on extensive scientific evidence about ozone’s effects.

EPA has designated areas meeting and not meeting the air quality standards for the 2006 and 2012 PM standards and the 2008 ozone standard, and has completed an initial round of area designations for the 2010 sulfur dioxide standard. The agency also issues rules or guidance for state implementation of the various ambient air quality standards – for example, in March 2015, proposing requirements for implementation of current and future fine particle standards. EPA is working with states to improve data to support implementation of the 2010 sulfur dioxide and nitrogen dioxide standards.

For areas not meeting the national air quality standards, states are required to adopt state implementation plan revisions containing measures needed to meet the standards as expeditiously as practicable and within time periods specified in the Clean Air Act (except that plans are not required for areas with “marginal” ozone levels).

EPA is helping states to meet standards for common pollutants by issuing federal emissions standards for new motor vehicles and non-road engines, national emissions standards for categories of new industrial equipment (e.g., power plants, industrial boilers, cement manufacturing, secondary lead smelting), and technical and policy guidance for state implementation plans. EPA and state rules already on the books are projected to help 99 percent of counties with monitors meet the revised fine particle standards by 2020. The Mercury and Air Toxics Standards for new and existing power plants issued in December 2011 are achieving reductions in fine particles and sulfur dioxide as a byproduct of controls required to cut toxic emissions.
Vehicles and their fuels continue to be an important contributor to air pollution. EPA in 2014 issued standards commonly known as Tier 3, which consider the vehicle and its fuel as an integrated system, setting new vehicle emissions standards and a new gasoline sulfur standard beginning in 2017. The vehicle emissions standards will reduce both tailpipe and evaporative emissions from passenger cars, light-duty trucks, medium-duty passenger vehicles, and some heavy-duty vehicles. The gasoline sulfur standard will enable more stringent vehicle emissions standards and will make emissions control systems more effective. These rules further cut the sulfur content of gasoline. Cleaner fuel makes possible the use of new vehicle emission control technologies and cuts harmful emissions in existing vehicles. The standards will reduce atmospheric levels of ozone, fine particles, nitrogen dioxide, and toxic pollution.

Air Pollution Challenges: Climate Change

EPA determined in 2009 that emissions of carbon dioxide and other long-lived greenhouse gases that build up in the atmosphere endanger the health and welfare of current and future generations by causing climate change and ocean acidification. Long-lived greenhouse gases , which trap heat in the atmosphere, include carbon dioxide, methane, nitrous oxide, and fluorinated gases. These gases are produced by a numerous and diverse human activities.

In May 2010, the National Research Council, the operating arm of the National Academy of Sciences, published an assessment which concluded that “climate change is occurring, is caused largely by human activities, and poses significant risks for - and in many cases is already affecting - a broad range of human and natural systems.” 1 The NRC stated that this conclusion is based on findings that are consistent with several other major assessments of the state of scientific knowledge on climate change. 2

Climate change impacts on public health and welfare

The risks to public health and the environment from climate change are substantial and far-reaching. Scientists warn that carbon pollution and resulting climate change are expected to lead to more intense hurricanes and storms, heavier and more frequent flooding, increased drought, and more severe wildfires - events that can cause deaths, injuries, and billions of dollars of damage to property and the nation’s infrastructure.

Carbon dioxide and other greenhouse gas pollution leads to more frequent and intense heat waves that increase mortality, especially among the poor and elderly. 3 Other climate change public health concerns raised in the scientific literature include anticipated increases in ground-level ozone pollution 4 , the potential for enhanced spread of some waterborne and pest-related diseases 5 , and evidence for increased production or dispersion of airborne allergens. 6

Other effects of greenhouse gas pollution noted in the scientific literature include ocean acidification, sea level rise and increased storm surge, harm to agriculture and forests, species extinctions and ecosystem damage. 7 Climate change impacts in certain regions of the world (potentially leading, for example, to food scarcity, conflicts or mass migration) may exacerbate problems that raise humanitarian, trade and national security issues for the United States. 8

The U.S. government's May 2014 National Climate Assessment concluded that climate change impacts are already manifesting themselves and imposing losses and costs. 9 The report documents increases in extreme weather and climate events in recent decades, with resulting damage and disruption to human well-being, infrastructure, ecosystems, and agriculture, and projects continued increases in impacts across a wide range of communities, sectors, and ecosystems.

Those most vulnerable to climate related health effects - such as children, the elderly, the poor, and future generations - face disproportionate risks. 10 Recent studies also find that certain communities, including low-income communities and some communities of color (more specifically, populations defined jointly by ethnic/racial characteristics and geographic location), are disproportionately affected by certain climate-change-related impacts - including heat waves, degraded air quality, and extreme weather events - which are associated with increased deaths, illnesses, and economic challenges. Studies also find that climate change poses particular threats to the health, well-being, and ways of life of indigenous peoples in the U.S.

The National Research Council (NRC) and other scientific bodies have emphasized that it is important to take initial steps to reduce greenhouse gases without delay because, once emitted, greenhouse gases persist in the atmosphere for long time periods. As the NRC explained in a recent report, “The sooner that serious efforts to reduce greenhouse gas emissions proceed, the lower the risks posed by climate change, and the less pressure there will be to make larger, more rapid, and potentially more expensive reductions later.” 11

In brief: What EPA is doing about climate change

Under the Clean Air Act, EPA is taking initial common sense steps to limit greenhouse gas pollution from large sources:

EPA and the National Highway and Traffic Safety Administration between 2010 and 2012 issued the first national greenhouse gas emission standards and fuel economy standards for cars and light trucks for model years 2012-2025, and for medium- and heavy-duty trucks for 2014-2018. Proposed truck standards for 2018 and beyond were announced in June 2015. EPA is also responsible for developing and implementing regulations to ensure that transportation fuel sold in the United States contains a minimum volume of renewable fuel. Learn more about clean vehicles

EPA and states in 2011 began requiring preconstruction permits that limit greenhouse gas emissions from large new stationary sources - such as power plants, refineries, cement plants, and steel mills - when they are built or undergo major modification. Learn more about GHG permitting

On August 3, 2015, President Obama and EPA announced the Clean Power Plan – a historic and important step in reducing carbon pollution from power plants that takes real action on climate change. Shaped by years of unprecedented outreach and public engagement, the final Clean Power Plan is fair, flexible and designed to strengthen the fast-growing trend toward cleaner and lower-polluting American energy. With strong but achievable standards for power plants, and customized goals for states to cut the carbon pollution that is driving climate change, the Clean Power Plan provides national consistency, accountability and a level playing field while reflecting each state’s energy mix. It also shows the world that the United States is committed to leading global efforts to address climate change. Learn more about the Clean Power Plan, the Carbon Pollution Standards, the Federal Plan, and model rule for states

The Clean Power Plan will reduce carbon pollution from existing power plants, the nation’s largest source, while maintaining energy reliability and affordability. The Clean Air Act creates a partnership between EPA, states, tribes and U.S. territories – with EPA setting a goal, and states and tribes choosing how they will meet it. This partnership is laid out in the Clean Power Plan.

Also on August 3, 2015, EPA issued final Carbon Pollution Standards for new, modified, and constructed power plants, and proposed a Federal Plan and model rules to assist states in implementing the Clean Power Plan.

On February 9, 2016, the Supreme Court stayed implementation of the Clean Power Plan pending judicial review. The Court’s decision was not on the merits of the rule. EPA firmly believes the Clean Power Plan will be upheld when the merits are considered because the rule rests on strong scientific and legal foundations.

On October 16, 2017, EPA proposed to repeal the CPP and rescind the accompanying legal memorandum.

EPA is implementing its Strategy to Reduce Methane Emissions released in March 2014. In January 2015 EPA announced a new goal to cut methane emissions from the oil and gas sector by 40 – 45 percent from 2012 levels by 2025, and a set of actions by EPA and other agencies to put the U.S. on a path to achieve this ambitious goal. In August 2015, EPA proposed new common-sense measures to cut methane emissions, reduce smog-forming air pollution and provide certainty for industry through proposed rules for the oil and gas industry . The agency also proposed to further reduce emissions of methane-rich gas from municipal solid waste landfills . In March 2016 EPA launched the National Gas STAR Methane Challenge Program under which oil and gas companies can make, track and showcase ambitious commitments to reduce methane emissions.

EPA in July 2015 finalized a rule to prohibit certain uses of hydrofluorocarbons -- a class of potent greenhouse gases used in air conditioning, refrigeration and other equipment -- in favor of safer alternatives. The U.S. also has proposed amendments to the Montreal Protocol to achieve reductions in HFCs internationally.

Air Pollution Challenges: Toxic Pollutants

While overall emissions of air toxics have declined significantly since 1990, substantial quantities of toxic pollutants continue to be released into the air. Elevated risks can occur in urban areas, near industrial facilities, and in areas with high transportation emissions.

Numerous toxic pollutants from diverse sources

Hazardous air pollutants, also called air toxics, include 187 pollutants listed in the Clean Air Act. EPA can add pollutants that are known or suspected to cause cancer or other serious health effects, such as reproductive effects or birth defects, or to cause adverse environmental effects.

Examples of air toxics include benzene, which is found in gasoline; perchloroethylene, which is emitted from some dry cleaning facilities; and methylene chloride, which is used as a solvent and paint stripper by a number of industries. Other examples of air toxics include dioxin, asbestos, and metals such as cadmium, mercury, chromium, and lead compounds.

Most air toxics originate from manmade sources, including mobile sources such as motor vehicles, industrial facilities and small “area” sources. Numerous categories of stationary sources emit air toxics, including power plants, chemical manufacturing, aerospace manufacturing and steel mills. Some air toxics are released in large amounts from natural sources such as forest fires.

Health risks from air toxics

EPA’s most recent national assessment of inhalation risks from air toxics 12 estimated that the whole nation experiences lifetime cancer risks above ten in a million, and that almost 14 million people in more than 60 urban locations have lifetime cancer risks greater than 100 in a million. Since that 2005 assessment, EPA standards have required significant further reductions in toxic emissions.

Elevated risks are often found in the largest urban areas where there are multiple emission sources, communities near industrial facilities, and/or areas near large roadways or transportation facilities. Benzene and formaldehyde are two of the biggest cancer risk drivers, and acrolein tends to dominate non-cancer risks.

In brief: How EPA is working with states and communities to reduce toxic air pollution

EPA standards based on technology performance have been successful in achieving large reductions in national emissions of air toxics. As directed by Congress, EPA has completed emissions standards for all 174 major source categories, and 68 categories of small area sources representing 90 percent of emissions of 30 priority pollutants for urban areas. In addition, EPA has reduced the benzene content in gasoline, and has established stringent emission standards for on-road and nonroad diesel and gasoline engine emissions that significantly reduce emissions of mobile source air toxics. As required by the Act, EPA has completed residual risk assessments and technology reviews covering numerous regulated source categories to assess whether more protective air toxics standards are warranted. EPA has updated standards as appropriate. Additional residual risk assessments and technology reviews are currently underway.

EPA also encourages and supports area-wide air toxics strategies of state, tribal and local agencies through national, regional and community-based initiatives. Among these initiatives are the National Clean Diesel Campaign , which through partnerships and grants reduces diesel emissions for existing engines that EPA does not regulate; Clean School Bus USA , a national partnership to minimize pollution from school buses; the SmartWay Transport Partnership to promote efficient goods movement; wood smoke reduction initiatives; a collision repair campaign involving autobody shops; community-scale air toxics ambient monitoring grants ; and other programs including Community Action for a Renewed Environment (CARE). The CARE program helps communities develop broad-based local partnerships (that include business and local government) and conduct community-driven problem solving as they build capacity to understand and take effective actions on addressing environmental problems.

Air Pollution Challenges: Protecting the Stratospheric Ozone Layer

The ozone (O 3 ) layer in the stratosphere protects life on earth by filtering out harmful ultraviolet radiation (UV) from the sun. When chlorofluorocarbons (CFCs) and other ozone-degrading chemicals are emitted, they mix with the atmosphere and eventually rise to the stratosphere. There, the chlorine and the bromine they contain initiate chemical reactions that destroy ozone. This destruction has occurred at a more rapid rate than ozone can be created through natural processes, depleting the ozone layer.

The toll on public health and the environment

Higher levels of ultraviolet radiation reaching Earth's surface lead to health and environmental effects such as a greater incidence of skin cancer, cataracts, and impaired immune systems. Higher levels of ultraviolet radiation also reduce crop yields, diminish the productivity of the oceans, and possibly contribute to the decline of amphibious populations that is occurring around the world.

In brief: What’s being done to protect the ozone layer

Countries around the world are phasing out the production of chemicals that destroy ozone in the Earth's upper atmosphere under an international treaty known as the Montreal Protocol . Using a flexible and innovative regulatory approach, the United States already has phased out production of those substances having the greatest potential to deplete the ozone layer under Clean Air Act provisions enacted to implement the Montreal Protocol. These chemicals include CFCs, halons, methyl chloroform and carbon tetrachloride. The United States and other countries are currently phasing out production of hydrochlorofluorocarbons (HCFCs), chemicals being used globally in refrigeration and air-conditioning equipment and in making foams. Phasing out CFCs and HCFCs is also beneficial in protecting the earth's climate, as these substances are also very damaging greenhouse gases.

Also under the Clean Air Act, EPA implements regulatory programs to:

Ensure that refrigerants and halon fire extinguishing agents are recycled properly.

Ensure that alternatives to ozone-depleting substances (ODS) are evaluated for their impacts on human health and the environment.

Ban the release of ozone-depleting refrigerants during the service, maintenance, and disposal of air conditioners and other refrigeration equipment.

Require that manufacturers label products either containing or made with the most harmful ODS.

These vital measures are helping to protect human health and the global environment.

The work of protecting the ozone layer is not finished. EPA plans to complete the phase-out of ozone-depleting substances that continue to be produced, and continue efforts to minimize releases of chemicals in use. Since ozone-depleting substances persist in the air for long periods of time, the past use of these substances continues to affect the ozone layer today. In our work to expedite the recovery of the ozone layer, EPA plans to augment CAA implementation by:

Continuing to provide forecasts of the expected risk of overexposure to UV radiation from the sun through the UV Index, and to educate the public on how to protect themselves from over exposure to UV radiation.

Continuing to foster domestic and international partnerships to protect the ozone layer.

Encouraging the development of products, technologies, and initiatives that reap co-benefits in climate change and energy efficiency.

The results of an analysis of changes in the atmospheric air quality in Moscow during the lockdown period and the decline in business activity caused by the COVID-19 coronavirus pandemic are presented. The observed changes in urban air pollution represent a unique experiment to assess the impact of various anthropogenic influences on the composition of atmospheric air. The influence of weather factors and transport activity on the level of pollution in the spring of 2020 is considered. The level of the main pollutants in the atmosphere decreased by 30–50% during the period of lockdown, and a different type of changes was revealed near highways and in residential areas. This article discusses the possibilities and difficulties of using a “unique experiment” on a sharp decrease in traffic intensity in large cities to determine the contribution of various branches of the urban economy (transport, energy, industry, waste processing) to the total air pollution in large cities.

INTRODUCTION

Natural and man-made disasters have a negative impact on the quality of life of mankind and the environment. Studying of these events creates new knowledge and technologies that can be used to prevent and mitigate the consequences of future disasters, improve the quality of life, and ensure the safety of the population.

Atmospheric air, water, and natural objects in large cities are most vulnerable to anthropogenic impact. The World Health Organization (WHO) estimates that diseases directly related to air pollution are responsible at present for 4.6 million deaths annually [ 1 ]. The anthropogenic impact is complex, since in urban agglomerations the climate, air quality, and the environment are simultaneously influenced by both global and regional natural factors (global warming, heat waves and cold snaps, etc.) and specific intra- and extra-urban factors (building, energy, industry, transport, landfills, etc.), the assessment of the relative importance of which is a difficult task (see for example [ 2 ]). In most large cities, it is difficult to distinguish the contribution of individual pollution sources, especially for various industrial enterprises and landfills, against the background of the main source of urban air pollution—transport. The atmospheric air composition in Moscow, the sources and concentrations of atmospheric pollutants, and trends in air quality in Moscow in comparison with the largest cities in the world are given in the reports of the Department of Natural Resources Management and Environmental Protection of Moscow (see, for example, [ 3 ]).

The COVID-19 pandemic has reduced by several times city traffic on the streets of Moscow and other cities in Russia and the world, accompanied by a noticeable economic recession and a decrease in industrial emissions that pollute the atmosphere of cities, as well as to a noticeable decrease in greenhouse gas emissions with possible climatic effects [ 4 ]. Ambient air quality monitoring data objectively demonstrate a significant reduction in the content of harmful substances. In many countries, especially in the densely populated areas of China and India [ 5 ], where aerosol air pollution is especially strong, since January of this year, there has been a sharp purification of air from suspended particles and engine emissions. Thus, the COVID-19 pandemic “set up a natural experiment” on the impact of a sharp decline in city traffic on urban air quality.

SOURCES OF AIR POLLUTION IN MOSCOW

The composition, concentration, and spatial–temporal distribution of the main air pollutants in Moscow are constantly monitored by automatic air pollution control stations (AAPCS network) of the State Budgetary Environmental Institution “Mosecomonitoring,” then annually summarized and analyzed in reports of the Department of Natural Resources Management and Environmental Protection of the Moscow Government. According to [ 3 ], within the boundaries of modern Moscow there are more than fifty AAPCSs located near highways, in residential, natural, and mixed territories. This paper analyzes the data of AAPCSs near highways and in residential areas ( Fig. 1 ).

Location of AAPCSs near highways and in residential areas within the boundaries of Moscow in 2011.

Due to the AAPCS network, the concentration of pollutants in the atmosphere of Moscow is quite well known. It is much more difficult to identify the main sources of Moscow air pollution. This is due to the fact that not all sources of air pollution in Moscow are located within the city’s administrative borders. At the same time, estimating emissions from various sources (transport, industry, waste) is a complex and difficult task, since the provision of data on emissions from various sectors of the urban economy is not always controlled by normative legal acts and is often a manifestation of the environmental responsibility of business. In addition, the transport and accumulation of pollutants in the city is highly dependent on specific meteorological conditions.

In Moscow, as in all large cities, the main source of pollutant emissions is motor transport, which creates a high spatial variability of pollution with a maximum near highways and a minimum in residential and suburban areas. The amount of vehicle emissions is a fully calculated value based on data on the emissions of different types of vehicles under different engine operating conditions.

The main contribution to emissions of pollutants by road transport in Moscow is made by carbon monoxide (almost 2/3 of all emissions); it is a product of incomplete combustion of fuel. The concentration of carbon monoxide depends on the configuration of the road network, traffic intensity, weather conditions, and street configuration. Its average concentration in recent years has been at the level of 0.36 mg/m 3 . Approximately 20% of transport emissions are nitrogen oxides, and slightly more than 10% are volatile hydrocarbons. Suspended particle emissions are about 1% excluding emissions from road surface abrasion and tires and brake pads of cars, which range from 2500 to 5000 tons/year [ 3 ].

CITY AIR DURING LOCKDOWN

Reductions in air pollution during the COVID-19 restrictions have been observed in many cities and regions of the world (see, for example, [ 4 – 7 ] and other publications in spring and summer 2020). Most of these publications are based on satellite observations of atmospheric gases (mainly nitrogen dioxide). Ground-based measurements of the dynamics of atmospheric pollution during lockdown have not yet been analyzed sufficiently. Only a few publications can be noted, for example [ 7 ], where the aerosol content was compared before and during lockdown in Almaty according to data from one station in the city center.

In Moscow, from early April to mid-May 2020, mainly reduced concentrations of pollutants were observed. This could have been due to the significant decrease in the traffic intensity of vehicles, emissions from which in a normal situation make up more than 90% of the total emissions of pollutants into the atmosphere of Moscow. According to the Moscow Department of Transportation, the Moscow motorway network workload in April 2020 was approximately four times less than in April 2019 [ 8 ].

The average concentrations of pollutants in April 2020 were lower than the average for the previous three years. At the same time, the decrease in air pollution manifests itself in different ways near highways and in residential areas ( Table 1 ).

Decrease in the average concentration of the main pollutants in the atmospheric air of Moscow in April 2020 compared to the average level in recent years (in percent) according to the data of the State Budgetary Environmental Institution “Mosecomonitoring”

Table 1 shows an interesting fact that characterizes the transport and deposition of pollutants in the city’s atmosphere and which shows that during the quarantine and the corresponding restriction of transport activity, the air inside residential areas was purified stronger than near highways.

It should be noted that it is particularly difficult to assess the impact of lockdown on air quality in Moscow in the second quarter of 2020. First, in the spring, after snow melt, an increase in the content of atmosphere pollutants and especially suspended particles usually happens in the Moscow Region. In 2020, there was an extremely snowless winter, as a result of which the seasonal trend of aerosol content in the Moscow air in the first half of the year could have been atypical. Second, at the end of March 2020, there was a period of a positive pressure anomaly, which led to a strong development of unfavorable meteorological conditions that contributed to the accumulation and a multiple increase in the content of pollutants in the surface layer of the atmosphere. This was followed by a decrease in pressure in April and the first half of May. Thus, the pressure trends from March to May were generally similar to the dynamics of the transport activity index in Moscow. Due to the meteorological features of spring 2020, in order to identify the causes of air quality changes during lockdown relative to the average data obtained by the State Budgetary Environmental Institution “Mosecomonitoring” for the period 2017–2019, a thorough analysis is required.

Changes in the average daily concentrations of pollutants in Moscow in March–May 2020 relative to the average values for 2017–2019 are shown in Fig. 2 . The sea level air pressure values are also shown. A sharp short-term jump in concentrations for March 27–28, as mentioned above, is associated with a powerful positive pressure anomaly and unfavorable conditions for dispersion of impurities. Despite the meteorological features of the spring of 2020, one can note the dependence of the content of a number of pollutants and, first of all, carbon monoxide on the decrease in transport activity in Moscow (transport activity was estimated according to the data of the Moscow Department of Transport [ 8 ]).

Change in (a) CO and (b) PM 10 concentrations in the spring of 2020 compared to the average values of 2017–2019 (in %) for AAPCSs near highways (red lines) and in residential areas (green lines). The purple line shows the atmospheric pressure at sea level according to the Balchug weather station (in hPa).

During the quarantine period, the Moscow Department of Transport promptly published data on the intensity of passenger traffic in public and private transport in the city. Since the passenger traffic of public transport is measured in millions of people transported per day, the data on personal transport flows were given in the same units. Data on public transport passenger flows are not very informative for the purposes of this study, since this transport includes not only buses, the emissions of which pollute the urban atmosphere, but also electrified transport—subway, electric trains, trams, and trolleybuses. Due to the predominant number of personal vehicles in the total number of cars on the roads of Moscow (according to Mosgortrans and the Traffic Management Center (TMC), the number of passenger cars exceeds the number of buses by more than 100 times) and the proportionality of the number of passengers to the number of cars, data on passenger traffic in terms of personal transport can be used as an index of general transport activity in the city.

In March 2020, before the lockdown, the CO content near highways significantly exceeded its content in the air of residential areas. In April and early May, the CO content in the city as a whole decreased significantly, while its concentrations near highways and in residential areas became closer to each other. Since the middle of May, as the restrictions were removed and transport activity increased, the CO concentration began to grow, and it increased near highways much faster than in residential areas ( Fig. 3 ).

CO concentrations trend in spring 2020 for stations near highways (red lines) and in residential areas (green lines). The dynamics of personal transport passenger traffic (million people/day) is shown in gray.

The importance of taking into account weather conditions for the interpretation of air purification in cities during quarantine has also been noted by American scientists [ 9 ]. According to them, the noticeable decrease in nitrogen dioxide (NO 2 ) content observed from satellite data in March–April 2020 in different cities of the United States depends significantly on the precipitation regime in the corresponding regions of the country. Similar conclusions were obtained for pollution in Chinese cities, where extremely high levels of pollution associated with weather conditions were observed against the background of a general decrease in the level during lockdown [ 5 ].

DISCUSSION AND CONCLUSIONS

An analysis of the improvement in air quality in Moscow during the restrictions imposed by COVID-19 showed a difference in the impact of a decrease in economic activity on the content of various atmospheric pollutants near highways and in residential areas of the city.

At the same time, difficulties were found in accounting for weather conditions for interpreting urban air purification during lockdown and comparing observations in the spring seasons of various years.

Further analysis of changes in the content of atmospheric pollutants in the context of a sharp decline in economic activity will help to improve methods for assessing the contribution of various sources to air pollution and the impact of reduced traffic on air quality.

For reliable quantitative assessments of the effect of reducing traffic and reducing economic activity on the content of pollutants in the urban atmosphere, it is necessary to take an inventory of the composition and amount of emissions of gas and aerosol pollutants into the atmosphere from various types of industrial enterprises, energy facilities, trade (including public catering facilities), everyday services, and other urban sectors, as well as landfills and waste processing enterprises, taking into account the specifics of various cities in Russia, such as Moscow, St. Petersburg, Omsk, and Chelyabinsk, where the ratio of emission sources is different and at the same time there is a sufficiently developed observation network.

The results of such a study can be used for planning the “green” development of the urban economy and environmental “improvement” of industrial enterprises.

Essay on Air Pollution – Causes, Effects, Solutions, Conclusion

Category: Essays and Paragraphs On November 20, 2018 By Aparna

Air Pollution

The whole world has been suffering from lots of problems since its existence, and the problems are getting bigger and bigger day by days.

One of the biggest problems that the entire planet faces is the amount of pollution on the planet. Pollution is of several kinds, but the pollution that affects the most to our nature and environment is Air pollution .

Air pollution is the pollution in which the pollutants get released in the air, and those pollutants then pollute the air which affects the health of a human being.

Air pollution is the pollution when the dirt, dirt particles and other kinds of pollutants get mixed to air and make the air polluted.

Today, every city in the world is suffering from air pollution , and that is why a lot of people and organizations in the world are trying their best to save the world from air pollution.

Air Pollution in India

Indian cities are much polluted and that can get seen from various visuals. Land and air pollution are connected directly as if the land is dirty, after a few days, that dirty land will lead to air pollution. In India, there are only a few surfaces where the pollution level is less. For example, the pollution level in Chandigarh city is lesser than a lot of cities in India. However, the pollution level in various cities of NCR, UP and Bihar is way higher than a lot of cities in India. The air pollution in India is getting increased day by day. But, the good news is that the people who had no interest in cleaning their country before, are now getting involved in schemes like Swachh Bharat Abhiyan, etc.

There are lots of causes of air pollution in the world and here are a few of those causes:

The burning of fossil fuels is the biggest cause of air pollution, and that is why it has been prohibited at a lot of places in the world.
Cars, buses, motorbikes are another big cause of air pollution because they emit a lot of pollution also.
Volcano eruptions are another big cause of air pollution.
When we cook at home, sometimes we need wood and charcoal for it, and these materials cause a huge amount of air pollution.
People smoking cigarettes is another big cause of air pollution.
If due to some reason a forest catches fire , then it becomes one of the biggest reasons for air pollution.

These are a few effects on human beings, plants, and animals due to air pollution:

The rainwater flows through the surface and ends in the river, and when the surface gets polluted, all the rainwater will take the polluted surface particles with itself which will not only pollute the river, but it will also pollute the land through which the water flows .
A lot of people suffer from allergies which are a side effect of living in an air-polluted
Air pollution can also lead to severe diseases like cancer, heart diseases, and other respiratory problems, etc.
One should restrict the use of charcoal , wood, thus the pollution caused by these resources would not be there in the world.
A restriction should be there on industries to use the kind of materials which causes zero to no air pollution at all.
The cities which have the maximum air pollution should get asked as to how they will reduce the air pollution and what are their plans for it.

Air pollution is a huge problem not only in India but the whole world, various organizations do their bit to make sure that plans are made to restrict air pollution , but unfortunately those plans never get executed rightly. That is why even after knowing that the air is getting polluted every day, the organizations around the world are unable to provide a good solution to it. As a human being, we must contribute, that is why, we need to gather and make sure that all the places, suffering from air pollution, should get organized in a manner so that air pollution should not exist. Everyone should participate in schemes like Swachh Bharat Abhiyan which will not only reduce the air pollution in the country but will also reduce various other kinds of pollution.
