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.

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.

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.

100 Words Essay on Air Pollution

200 words essay on air pollution, 500 words essay on air pollution.

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.

Essays on air pollution in 200 words, essays on air pollution in 500 words, 10 lines on 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.

Essay on Air Pollution: Types, Causes & Effects of Air Pollution

March 10, 2021 by Sandeep

Air Pollution Essay: Air Pollution can be defined as the presence of toxic substances in the air in such a concentration that can be hazardous to humans and their surroundings. These toxic particles are commonly known as pollutants; out of these pollutants, oxides of carbon, nitrogen and sulphur are particularly harmful.

Essay on Air Pollution in 500 Words

Below we have provided Air Pollution Essay in English, suitable for class 3, 4, 5, 6, 7, 8, 9 and 10 school students. This essay is drafted in easy and simple language.

Air Pollution is an environmental issue that poses a huge threat to billions of organisms surviving on our planet. It has been increasing at an alarming rate with an increase in the concentration of pollutants. The contamination of air by these hazardous pollutants has disrupted the natural balance in our environment. The quality of life has reduced.

Causes of Air Pollution

Two primary phenomena cause air pollution. One of them is the natural phenomenon that comprises volcanic eruptions, wildfires, radioactive elements, and volatile organic compounds. The other most crucial cause is human activity. With the increase in the number of industries, the contamination in the air automatically increases. Fuels and chemicals utilized in factories, mills, and industries release harmful chemicals to the atmosphere. These are organic compounds, gases, particulate matter, ash, and other volatile substances.

Chlorofluorocarbons, also known as CFCs, are another potent reason for air pollution. These chemicals get released from leaky refrigerants, spray tins, burning plastics and various other sources. They deplete the ozone layer and allow harmful UV rays to enter our atmosphere. This, in turn, causes serious illnesses. It is also responsible for smog in urban cities. Smog impairs visibility and can lead to accidents.

Carbon dioxide solely accounts for almost 57 percent of the air pollution. Greenhouse gases and Carbon dioxide together contribute to global warming . They also cause acid rains which are harmful to plants and man-made objects like ancient monuments.

Effects of Air Pollution

With the air quality deteriorating, our future is at stake. Increasing pollution can cause serious health hazards like cancer and cardiovascular issues. Children suffer from bronchitis and pneumonia. Irritation of the nose and throat, asthma attacks, pulmonary diseases are all outcomes of air pollution. Another significant effect of pollution is extreme climate change. Disrupting food chains, extinction of species, depleting the ozone layer are some of the grave issues we face today.

Control of Air Pollution

The Air Pollution Act forbids power sectors and high-scale industries from releasing particulate matter beyond a certain level. Chimneys, Electrostatic precipitators, and filters must be implanted to lessen the damage caused by the emissions.

People must be made aware of the grave conditions of air pollution. The government has taken a huge step to sensitize people regarding the consequences of pollution. We must do our part as well. Using the means of public transport will ensure less number of vehicles. Lesser vehicles mean lesser emission of pollutants.

Planting more and more trees can help solve this crisis. Reforestation in mining areas is also an effective step. Conservation of energy is of prime importance. Renewable energy sources like solar panels, wind turbines, hydroelectric power, and natural gas must be utilized. We must avoid burning dry leaves at our homes and must indulge in the habit of composting.

The implementation of Eco-friendly methods will ensure a cleaner and healthier environment. LPG (Liquefied Petroleum Gas), CNG (Compressed Natural Gas), and Biogas are some Eco-friendly substitutes of fuels. Together, we must strive to bring a change. Our efforts matter because they will bring in much-needed change. After all, everyone wants to live on a healthy planet.

The presence of unusually high concentrations of harmful or poisonous substances in the environment (air, water, etc.) is called pollution . Pollution contaminates the air and water with poisonous substances and makes them impure to such an extent that they become harmful to the human beings, other animals, plants as well as to the non-living things.

An unwanted and harmful substance that contaminates the environment (such as air and water) is called a pollutant.

The two main gases present in air are nitrogen and oxygen. Nitrogen makes up about 78% of air whereas oxygen makes up about 21% of air by volume. Air also contains small amounts of carbon dioxide, argon and water vapour.

In addition to the normal constituents, the polluted air may also contain harmful substances such as carbon monoxide, sulphur dioxide, nitrogen oxides, smoke and dust, etc. Many respiratory problems are caused by breathing in polluted air.

Fresh water (usable water) is present in rivers, lakes and ponds. Some fresh water is also present under the ground. Due to increasing water pollution, water-borne diseases are also increasing day by day.

The contamination of air with harmful gases (like sulphur dioxide nitrogen oxides, carbon monoxide), smoke and dust, etc. is called air pollution .

The substance whose presence in air makes it impure or contaminated is called an air pollutant.

A substance becomes an air pollutant when it is present in air in such concentration which is high enough to have a harmful effect on the living  or non-living things.

The major pollutants which cause air pollution are : Sulphur dioxide, Nitrogen monoxide, excess of Carbon dioxide, Chlorofluorocarbons, and Suspended particulate matter (such as Dust, Smoke and Fly ash)

Sources of Air Pollution

Most of the air pollution is caused by the burning of fuels such as wood, cow-dung cakes, coal ,kerosene, petrol and diesel in homes, motor vehicles (automobiles), factories and thermal power plants.

The various sources of air pollution are:

(1) Smoke emitted from homes by the burning of fuels like wood, cow-dung cakes, kerosene and coal.

(2) Exhaust gases emitted by motor vehicles (automobiles) due to burning of petrol and diesel.Motor vehicles are the major cause of air pollution in big cities.

(3) Smoke emitted by factories and thermal power plants due to burning of coal.

(4) Oil refineries and industries engaged in the production of metals and manufacture of chemicals.

(5) Stone crushers, cement factories, asbestos factories and lead processing units cause air pollution.

(6) Use of chlorofluorocarbons in refrigeration, air conditioning and aerosol sprays. 

(7) Smoking causes air pollution

(8) Forest fires and volcanic eruptions are the two natural sources of air pollution which put smoke and dust into the air.

Harmful Effects of Air Pollution

Sulphur dioxide.

(1) Sulphur dioxide is produced by the burning of coal in factories and thermal power plants.

(2) Sulphur dioxide is also produced by the burning of petrol and diesel in motor vehicles.

(3) Oil refineries also emit sulphur dioxide gas into air.

(1) Sulphur dioxide gas in the air causes respiratory problems.

(2) If may even cause permanent lung damage.

(3) Sulphur dioxide gas in polluted air produces acid rain. This acid rain damages trees, plants, soil, aquatic animals (like fish) statues, buildings and historical monuments.

(4) Sulphur dioxide also contributes to the formation of a deadly air pollutant called smog.

Nitrogen Oxides

(1) Nitrogen oxides are produced by the burning of fuels like petrol and diesel in motor vehicles.

(2) They are also produced by the burning of coal in factories and thermal power plants.

The high temperature produced by the burning of fuels like petrol, diesel and coal makes some of the nitrogen and oxygen of air to combine to form nitrogen oxides.

(3) Oil refineries also produce and emit nitrogen oxides into the air.

(1) Nitrogen oxides attack breathing system and lead to lung congestion.

(2) They also attack skin.

(3) Nitrogen oxides present in polluted air produce acid rain.

(4) Nitrogen oxides also contribute to the formation of smog.

Smog is a deadly air pollutant which is formed by the combination of smoke and fog( The minute water particles suspended in air near the surface of earth during cold weather in winter is called fog.)

Smoke contains tiny carbon particles, and harmful gases such as nitrogen oxides and sulphur dioxide. The carbon particles, nitrogen oxides and sulphur dioxide of smoke combine with the condensed water vapour called fog to form smog.

Smog causes cough and aggravates (makes worse) asthma and other lung diseases, especially in children.

Carbon Monoxide  

(1) Carbon monoxide is produced by the incomplete combustion of fuels like wood, coal, kerosene, petrol and diesel in homes, factories and motor vehicles.

(2) The exhaust gases of motor vehicles (cars, buses and trucks, etc.) contain carbon monoxide which they emit into air.

(3) Cigarette  smoke also contains carbon monoxide.

Carbon monoxide is a very poisonous gas.When inhaled carbon monoxide combines with the haemoglobin of our blood and reduces the oxygen-carrying capacity of blood.Due to this, blood is not able to carry sufficient oxygen to our body parts. This lack of oxygen cause  respiratory problems (breathing problems). It causes suffocation. If too much carbon monoxide is inhaled, it may even cause death.

Carbon Dioxide

Carbon dioxide is produced in excessive amounts by the burning of large quantities of fuels such as wood, coal, kerosene, petrol, diesel, LPG, and CNG in homes, factories and motor vehicles.

Excess of carbon dioxide in air is considered a pollutant (because it produces undesirable changes in the environment). Carbon dioxide is the main greenhouse gas which traps sun’s heat in the earth’s atmosphere by producing greenhouse effect which leads to global warming.

Chlorofluorocarbons (CFCs)

Chlorofluorocarbons are the chemical compounds made of chlorine, fluorine and carbon elements. Chlorofluorocarbons are used in refrigerators, air conditioning and aerosol sprays.

Chlorofluorocarbons are industrially useful gases but they also behave as air pollutants because of their damaging effect on ozone layer.

Chlorofluorocarbons are depleting the useful ozone layer of the upper atmosphere. Chlorofluorocarbons released into the air go up and ultimately reach high into the atmosphere where the protective ozone layer exists. They react with the ozone gas of ozone layer and destroy it gradually. Ozone layer prevents the harmful ultraviolet radiations of the sun from reaching the earth. The destruction of ozone layer by CFCs will allow the extremely harmful ultraviolet radiations of the sun to reach the earth. These ultraviolet radiations can cause skin cancer, cataract, and destruction of plants, including crops. A big hole has already been made by the destruction of ozone gas in the ozone layer over the South Pole of the earth. It is called “ ozone hole “.

Suspended particulate matter (SPM) 

The finely divided solid or liquid particles suspended in air are called suspended particulate matter.

Some of the examples of suspended particulate matter are : Dust, Smoke and Fly ash. 

(a) Dust consists of tiny particles of earth: Dust is produced by blowing wind, heavy traffic on roads, stone crushers and construction activities.

(1) Dust in air spoils our clothes and reduces visibility.

(2) Dust produces allergic reactions in human body and aggravates diseases like bronchitis.

(3) Dust covers the leaves of plants and trees and prevents photosynthesis.

(b) Smoke is mainly tiny particles of carbon in air. Smoke is produced by the burning of fuels like wood, cow-dung, cakes, kerosene, petrol, and diesel in homes, factories, thermal power plants and motor vehicles.

Smoke present in air spoils our clothes and blackens the buildings. Smoke attacks our lungs and causes respiratory diseases.

(c) The minute ash particles formed by the burning of coal and carried into air by the gases produced during burning, is called fly ash.

Fly ash particles present in air cause irritation to the eyes, skin, nose, throat and respiratory tract. Continued breathing in air containing fly ash causes diseases like bronchitis and lung cancer.

The two extremely harmful effects of air pollution on the environment are acid rain and greenhouse effect (or global warming).

Controlling Air Pollution

Some of the ways of controlling air pollution are:

(1) The air pollution can be controlled by using smokeless fuels like LPG, PNG (Piped Natural Gas and Bio-gas for cooking food (instead of wood, cow-dung cakes, or coal). Solar cookers can also be used for cooking food. Solar water heaters should be installed for obtaining hot water.

(2) The air pollution from motor vehicles can be reduced by using CNG (Compressed Natural Gas) as fuel in place of petrol and diesel. CNG is a very clean fuel which does not pollute air

(3) The air pollution from factories, thermal power plants, oil refineries and chemical industries can be controlled by washing down their smoke and waste gases with jets of water. When the smoke and waste gases are sprayed by jets of water before they reach chimney, then soot present in smoke is washed away and most of the poisonous gases like sulphur dioxide and nitrogen oxides get dissolved in water.

(4) The air pollution can be controlled by using non-polluting sources of energy like solar energy, wind energy and hydroenergy for generating electricity. This will reduce the use of fossil fuel like coal which is used for generating electricity at thermal power plants and causes air pollution.

Role in Controlling Air Pollution

Some of the steps which can be taken as individuals (or as a group of individuals) to control air pollution and improve the quality of air around us are as follows :

(1) We should not burn dry leaves, papers and garbage in the open : Leaves should be converted into compost by burying in a pit ; used papers should be sent to paper mills for recycling; and garbage should be deposited in the garbage dumps established by the Municipal Corporation of the city.

(2) We should save electricity: If all of us start saving electricity by avoiding its wastage in homes, schools, shops, offices and factories, the demand for electricity will decrease. This will lead to the burning of less coal to generate electricity. And burning of less coal will reduce air pollution.

(3) We should grow more trees and also take care of the existing trees in our neighbourhood. Trees reduce pollution by absorbing excess carbon dioxide from the air. 

(4) We should join “Say No to Crackers” campaign organised by children of many schools during Diwali days to reduce the level of air pollution during the festival season.

(5) We should use bicycle for covering short distances. This will save precious fuel like petrol (which we use in cars, scooters and motorcycles) and also reduce air pollution.

(6) We should use the school bus or public transport bus for going to school.

Essay "Environmental Pollution" in 200 words - Class 8 PDF Download

The air we breathe, the water we drink, the security of creatures we drink, the security of creatures we share with, and fertility of land on which we grow our food are all deteriorating resulting in the increase of health hazards and lowering standard of health of the nation as a whole, In this seemingly desperate situation how to let our optimum survive is a burning question of the day.

A study conducted by the World Bank in 1995 revealed that 40,000 Indians die prematurely due to polluted air in cities. Yet another study made by the Environment protection Agency shows that every nearly 40,000 children in India are affected by respiratory diseases caused by the growth of carbon dioxide in the atmosphere. Air pollutants are continually poisoning our bones and the most susceptible to pollution are children below five years and elderly persons above 50 years. In general, those who have hyper-responsiveness to the presence of pollutants are bit harder than others. Air pollutants increase the risk of lung disease in asthma patients. Women with previous lead exposures may have elevated blood level during period of high bone turnover as observed during pregnancy, location or hyperthyroidism. Their unborn fetuses may be exposed to this danger as also the new born though breast milk. Children have relatively narrower air passages which are more easily obstructed. They need more oxygen whereas they inhale larger volumes of polluted air. Children are three times more at risk & exposure to pollutants floating in the sky than adults. In Delhi every tenth school going kid is suffering from asthma caused by air pollution. Traffic police men, automobile mechanics, drivers, cyclists, rikshaw-walas, road side vendors and hawkers all inhale more pollutants than others due to the nature of their work.

Vehicular discharged is the most important of pollutants which is wrecking the health of urban populace. Human body can tolerate up to 0.25 milligram of lead in blood. But a resident of cities like Delhi, Mumbai, and Chennai through vehicles.

Air pollution is not visible to the naked eye nor can it be handled or removed by individual efforts. Polluted water can be purified before drinking, polluted food can be done away with, noise pollution can also be controlled by individual efforts but air pollution can be controlled only by the ruling authority. In Singapore owning and running a car has been made so expensive that fewer people dare possess a car. There are many zones in European countries where vehicles are prohibited from plying; High registration fees and restriction on the movement of vehicles can go a long way in saving us from toxns. Keeping half the existing vehicles off the road for two days in a week, improving the quality of fuel and traffic management may also be helpful.

These are all prohibitive measures, which can be enforced only by the Government. Certain protective measures should also be adopted for effective control of this menace. Tree plantation can go a long way to balance the ratio of carbon dioxide in atmosphere. During photosynthesis plants absorb carbon dioxide and release oxygen. Hence plantation of trees wherever possible and ban on cutting of green trees will help in maintaining proper balance in atmosphere. Agricultural land must also be kept under one crop or the other. This will not only protect from air pollution but will also put a check to soil erosion which is an important factor responsible for the loss of fertility of soil.

Water pollution can be checked by keeping our rivers, canals and lakes clean. Industrial wasted must also be disposed off in such a way that it does not contribute to pollution of air and water. At no cost it should be allowed to find its way to the rivers. Use of insecticides in agricultural crops, fruit trees, garden and vegetable crops as also in houses should be judiciously planned.

Noise pollution can be easily and effectively controlled by our individual and social efforts. Proper tuning of musical sets, radios, loudspeakers, T.V. sets and vehicle horns etc. should be practiced.

These should be sustained efforts to find alternatives like solar powered vehicles and appliances to reduce our dependence upon oil engines to run vehicles and generator sets. Only when the problem is tackled on war footing can we control this problem of pollution.

Access Class 7 Science Chapter 18 - Pollution of Air and Water

Pollution is a change in the physical, chemical, or biological features of air, water, or land that can be damaging to human life and other creatures, as well as living circumstances, industrial operations, and cultural assets.

Pollutants are the agents that cause pollution in our environment. Pollutants are substances that pollute the air, water, or land. For eg. smoke, dust, fog and gases like sulphur dioxide and nitrogen dioxide.

The contamination of air by contaminants that can harm live creatures and nonliving components is known as air pollution.

Air Pollution Sources:

Sources from nature: Forest fires or volcanic eruptions produce smoke and dust. Methane gas is produced as a result of the decomposition of organic matter.

Man-made Exhaust gases from factories, power plants, and autos are among the sources.

The principal air pollutants include carbon monoxide, nitrogen oxides, carbon dioxide, methane, and sulphur dioxide.

Smog is a mixture of smoke and chemicals in the air, along with the fog. Ozone, sulphur dioxide, nitrogen dioxide, and carbon monoxide are some of the chemical components of smog. Smog can exacerbate breathing problems such as asthma and coughing.

Steps to reduce air pollution include: 

Using CNG and unleaded gasoline in autos.

Using alternative fuels such as solar, hydropower, and wind energy. 

Trees are being planted.

Bicycling, taking public transportation or carpooling to school.

Keeping leaves, rubbish, and vegetable debris from being burned.

Cigarette smoking restrictions.

Global warming is caused by rising quantities of greenhouse gases such as CO₂ and CFC (Chlorofluorocarbon). Excessive usage of CFCs depletes the ozone layer, which protects the earth from the sun's harmful UV rays.

Greenhouse Effect and Global Warming: 

The sun's rays warm the earth's surface, causing the greenhouse effect and global warming. The earth absorbs some of the radiation that falls on it and reflects some of it back into space. Because of the presence of greenhouse gases such as water vapour, carbon dioxide, methane, and nitrous oxide, a portion of the reflected radiation gets trapped in the atmosphere. This is referred to as the greenhouse effect.

The stored radiation warms the globe, even more, causing problems like glaciers melting and rising sea levels. Global warming is the name given to this occurrence.

Water pollution is defined as the contamination of water by undesirable and harmful things such as sewage, poisonous chemicals, silt, and other contaminants. Some of the biggest impurities of water are sewage, agricultural chemicals, and industrial waste.

Potable water is water that has been filtered and is safe to drink. Water is an extremely valuable natural resource. It is imperative that we learn to conserve it.

In 1985, the Ganga Action Strategy, an ambitious plan to save the river, was established. Its goal was to lower the river's pollutant levels. However, the growing population and industrialisation have already irreversibly ruined this majestic river. In 2016, the Indian government established a new project called the National Mission for Clean Ganga (NMCG).

What is pollution.

Environmental pollution can be defined as undesirable changes that happen in the surrounding. These changes have negative and adverse effects on animals, plants, and other physical and biological components of the environment.

Pollutants can either be present in gaseous, solid, or liquid form. A substance can also be classified as being a pollutant when the concentration of that substance is greater than its natural levels. Also, this increase in the concentration of the substance can be caused due to natural or human activities.

Apart from air and water pollution, there are other different types of pollution. The different types of pollution are:

Light pollution

Sound pollution

Soil pollution

Students can learn about these other types of pollutants in other Science Class 8 Chapter Notes.

Understanding Air Pollution

Let’s attempt to understand the Pollution of Air And Water Class 8 Notes by looking at the basics. It is also possible for air to get polluted from natural sources like dust and smoke. This dust and smoke can arise from volcanic eruptions or forest fires. There are also man-made pollutants like power plants, automobile exhaust, and the burning of firewood.

Further, nitrogen oxides, carbon dioxide, methane, carbon monoxide, and sulphur dioxide are major pollutants of the air. It should be noted here that increasing levels of carbon dioxide is one of the major causes of global warming. We will look at the topic of global warming at a later point in these Class 8 Science Ch 18 Notes.

Air pollution can be explained as the introduction of organic molecules, pollutants, and other harmful substances into the atmosphere of the earth. The sources of air pollution can also be classified into two types. These types are:

Natural (For example, dust storms, forest fire, and volcanic activity)

Man-made (For example, homes, power plants, industries, transportation, and oil refineries)

There are also Many Effects of Air Pollution. and Some of Those Harmful Effects are:

Endangers animal welfare and health of vegetation and plants

Results in birth defects in new-born babies

Can result in allergies, diseases, and even death to humans

Earlier, we talked about some air pollutants. Now, we will look at all those air pollutants in detail. 

Carbon Monoxide and Carbon Dioxide

Some sources of carbon monoxide are incomplete combustion of carbon-containing compounds, like fuels and other toxic air pollutants. Carbon dioxide, on the other hand, can be produced as a by-product of burning fuels like coal, wood, natural gas, oil, and gasoline. It can also be produced during deforestation and cement production.

Nitrogen and Sulphur

It is important to mention in the notes of Chapter 18 Science Class 8, that both sulphur dioxide (SO₂) and nitrogen dioxide (NO₂) are major pollutants of air. Some sources of sulphur and nitrogen dioxide are the combustion of fossil fuels like coal in power plants and petroleum refineries. There are also various effects of nitrogen and sulphur dioxide, including acid rain, respiratory diseases like permanent lung damage, and photochemical smog-like breathing difficulties.

Particulate Matter

Particulate matter is also an important pollutant that is mentioned in the notes of Chapter 18 Science Class 8. It can be defined as particles of liquid or solid that remain suspended in water, gas, or air. Dust, debris, pollens, smoke, and acid droplets are some examples of particulate matter. Causes of particulate matter are construction, combustion, power plants, road dust, agricultural activities, industries, and deforestation. Particulate matter can cause birth defects, heart diseases, respiratory diseases, and asthma.

Smog is the combination of fog and smoke. There are different types of smogs. These types of smogs are:

Photochemical Smog - Photochemical smog is mainly found in areas that have a sunny and dry climate. It is caused due to a large number of automobiles. It is also the result of chemical interactions between sunlight and nitrogen oxides.

Classical Smog - Classical smog occurs in areas that have a humid climate and high concentrations of sulphur oxides in the air. It is the combination of fog, smoke, and sulphur dioxide gas.

According to Class 8 Pollution of Air and Water Notes, there are many harmful effects of smog. Some of those effects are:

It causes issues in plant growth and can also result in widespread damage to forests and crops

Breathing problems like cough, asthma, and wheezing

It can also cause corrosion of building materials, metals, and painted surfaces

Chlorofluorocarbons (CFCs)

According to Chapter 18 Class 8 Science Notes, CFCs are compounds that are made from fluorine, chlorine, and carbon. CFCs are mainly used as components of aerosol sprays and refrigerants in ACs, refrigerators, and cooling plants.

CFCs harm the ozone layer, which protects the earth from the ultraviolet (UV) radiation from the sun. Because of the increased amount of UV rays, individuals can suffer from diseases like eye damage, skin cancer, and suppression of the immune system.

Another important topic that elaborated in in these NCERT Class 8 Science Ch 18 Notes is the effect of air pollution on the Taj Mahal. There are various components or pollutants in the air that get accumulated in the air. This acid drops down with the rain to make it acidic. The reactions involved in this phenomenon are:

CO₂ (g) + 2H₂O (l) → 2H₂CO₃ (aq)

2SO₂ (g) + O₂ (g) 2H 2 O (l) → 2H₂SO₄ (aq)

4NO₂ (g) + O₂ (g) + 2H 2 O (l) → 4HNO₃ (aq)

This acid rain corrodes the marble of the Taj Mahal. This results in the marble turning from white to black. Many steps have been taken by the government to solve this problem and protect the marble of the Taj Mahal.         

What is Global Warming?

According to experts, global warming can be defined as a phenomenon in which gases that are responsible for the greenhouse effect, accumulate and trap more heat. Greenhouse gases capture a percentage of the sun’s radiation to maintain the temperature on the earth in a phenomenon known as the greenhouse effect.

This is different because most of the solar radiations that are passing through the atmosphere should bounce back into space. But due to the excess of greenhouse gasses, these radiations get trapped in the atmosphere. This makes the earth hotter than it should be.

In other words, it can be said that if greenhouse gases are trapping an appropriate amount of heat, then that is called the greenhouse effect. But if there are more greenhouse gases and more heat is being trapped than necessary, then that is called global warming.

Readers should also know what greenhouse gases are. The greenhouse gases mainly are - carbon dioxide, nitrous oxide, water vapes, and methane. We also know that global warming has many negative effects on the earth. But what are those effects? If you want to learn about those effects, then you should go through the list that is mentioned below.

Global warming has resulted in an increase in the average temperature of our planet

There has also been an increase in the severity and occurrence of natural disasters like cyclones, floods, and earthquakes

Climate patterns have shifted dramatically all across the globe

There has also been a rise in the average sea levels all across the globe. This is happening because the polar ice caps are melting

All of These Effects are Drastic and Can Even Destroy Life on Earth. So, What Can We Do?

It is recommended that everyone should try to protect the environment as much as possible. There are some steps that can be practised at an individual level. Some of those measures are:

Use cleaner fuels as compared to diesel and petrol

Use unleaded petrol. This is because unleaded petrol does not emit harmful gases into the environment

Waste should be properly managed. It should not be left in the open. Instead, waste should be incinerated or disposed of in a safe manner

You should try to carpool or use public transport because it is economical, prevents congestion on roads, and also reduces the emission of harmful gases to a large extent

What is Water Pollution?

Water pollution can be defined as the contamination of water bodies because of harmful waste. It can be caused due to industries, urbanization, social practices, religious practices, and agriculture.

In recent years, the biggest example of water pollution has been the river Ganga. The river Ganga has been polluted by many water pollutants like insecticides, hospitals, chemicals, detergents, and herbicides.

Apart from the river Ganga, there are many rivers that are filled with nothing but garbage, untreated sewage, and dead bodies of animals. All of this is choking aquatic life and hindering the growth of plants inside water bodies. According to various sources, Ganga is one of the ten most endangered rivers in the world. 

Water Can Be Broadly Classified As

Potable Water: It is the water that is suitable for drinking. It is free from all harmful bacterias and contaminants

Raw Water: It is the water that is not potable or fit for drinking

Converting Raw Water to Potable Water

It is possible to kill all the bacteria and microbes in water by boiling water. Boiling water also protects individuals against various waterborne diseases. Filtering water can also work. It is the process that separates suspended solid matter from a liquid. However, this method will only work to a certain extent.

Chlorination is another process that can help in cleaning water. This process is done by adding chlorine tablets or bleaching powder to the water. This method kills various bacterias and microbes that are present in tap water.

Chlorination is a more complex procedure than you might have understood from this description. This is why we have attached an image below. This image showcases the process of chlorination. It is suggested that readers should go through this image carefully to understand chlorination in a better manner.

(Image to be added soon)

With all being said, one question that still remains unanswered is how crucial are water and air. We have answered this question in the list that is mentioned below.

Importance of Air

Air is an inevitable part of our lives

It helps in producing energy in our bodies

It is vital for the survival of the animals and plants

Importance of Water

It plays a vital role in sustaining life on earth

Water helps in carrying out various human activities like drinking, agriculture, cleaning, and washing

Fun Facts about Pollution

Did you know that pollution is one of the biggest killers in the world? According to official sources, pollution affects over 100 million people all across the globe every single year! These numbers are comparable to the statistics of global diseases like HIV and malaria.

According to a study carried out by the National Academy of Sciences in 1975, industries have dumped almost 14 billion pounds of garbage into the oceans. Also, because of pollution, almost 1 million seabirds and 100,000 sea mammals are killed due to pollution every single year. Further, if you live in places with high levels of air pollutants, then you are at a 20% higher risk of dying from lung cancer in comparison to other people who live in less polluted areas.

It is essential to understand the concept of environmental pollution from an early age so that we can take necessary actions to protect our planet. In this essay, we will explore the topic of environmental pollution specifically tailored for Class 6 students, providing them with a descriptive understanding of the subject.

Environmental pollution refers to the contamination of the environment with various harmful substances and activities. These pollutants can be in the form of solid, liquid, or gas, and they adversely affect our air, water, soil, and overall ecosystem. Pollution can be caused due to both natural and human activities.

Air pollution is one of the prominent forms of environmental pollution. It occurs when harmful gases, particulate matter, and substances such as smoke, dust, and chemicals are released into the air. The sources of air pollution include vehicle exhaust, industrial emissions, burning fossil fuels, and deforestation. Breathing polluted air can lead to respiratory issues, allergies, and even serious health problems.

Water pollution is another significant concern. It happens when harmful substances like chemicals, industrial waste, sewage, and plastics find their way into water bodies like rivers, lakes, and oceans. These pollutants contaminate the water, making it unsafe for humans, animals, and plants. Water pollution affects aquatic life, disrupts the food chain, and can cause waterborne diseases.

Environment Pollution Paragraph for Class 5

Title: environment pollution paragraph for class 5.

The environment is the natural world around us, including the air we breathe, the water we drink, and the land we live on. Unfortunately, pollution has become a significant threat to our environment. Pollution means the presence or introduction of substances or elements that cause harm to the environment. In this paragraph, we will discuss the different types of pollution and their consequences.

Air pollution occurs when harmful substances are released into the air we breathe. Factories and vehicles are major sources of air pollution. When we burn fossil fuels like coal, oil, or gas, it releases pollutants such as carbon dioxide and harmful gases like sulfur dioxide and nitrogen oxides. Breathing in polluted air can cause respiratory problems and even lead to chronic diseases like asthma.

Water pollution happens when harmful chemicals, trash, or sewage are discharged into bodies of water, such as rivers, lakes, and oceans. This could be from industries that release toxins into water bodies or improper waste management practices. Water pollution not only affects aquatic life but also poses a threat to humans who consume contaminated water. It can lead to diseases like cholera and dysentery, and even affect our ecosystems.

Soil pollution occurs when harmful chemicals, pesticides, or industrial waste contaminate the soil. Excessive use of fertilizers and pesticides in agriculture is a major cause of soil pollution. Polluted soil affects the growth of plants, leading to reduced crop yields. Additionally, when we consume plants grown in polluted soil, it can have adverse effects on our health.

Noise pollution refers to excessive noise that is annoying or harmful to humans or animals. This includes noise from vehicles, construction sites, factories, or even loud music. Continuous exposure to high levels of noise can cause hearing loss, stress, and sleep disturbances. It can also disrupt wildlife habits, leading to imbalanced ecosystems.

Pollution is a severe issue that threatens our environment and our health. It is important for us to understand the different types of pollution and their consequences. Everyone, regardless of age, should be aware of the actions they can take to reduce pollution. Simple steps such as conserving energy, recycling, and using eco-friendly products can make a significant impact. By working together, we can protect our environment and ensure a better future for ourselves and upcoming generations.

Essay on Environmental Pollution in 500 words

Title: environment pollution – paragraph 1.

The issue of environmental pollution is a pressing concern that affects every living being on our planet. Pollution, in various forms, poses a significant threat to the delicate balance of ecosystems, jeopardizes human health, and hampers the sustainability of our natural resources. In this descriptive paragraph, we will explore the different types of environmental pollution and their detrimental impacts.

One of the most prevalent and well-known types of pollution is air pollution. It is caused by the release of harmful substances into the atmosphere, primarily through human activities such as burning fossil fuels, industrial operations, and vehicular emissions. These pollutants include carbon dioxide (CO2), sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter (PM).

The consequences of air pollution are vast and far-reaching. They range from respiratory diseases such as asthma and bronchitis to long-term effects like lung cancer and cardiovascular problems. Moreover, air pollution can also harm plant life and disrupt the natural balance of the environment, leading to reduced agricultural productivity and ecosystem instability.

Water pollution is another major environmental concern that occurs when contaminants are introduced into bodies of water, including rivers, lakes, oceans, and underground aquifers. Sources of water pollution include industrial waste, sewage, agricultural runoff, and oil spills. These pollutants affect the quality of water, making it unfit for consumption or harmful to aquatic biodiversity.

The impact of water pollution is manifold. Contaminated water poses severe health risks, causing waterborne diseases like cholera, dysentery, and typhoid. Additionally, it also disrupts marine ecosystems by suffocating aquatic life, damaging coral reefs, and depleting fish populations. Ultimately, water pollution creates a ripple effect, affecting everything from ecosystem stability to our own food supply.

Soil pollution occurs due to the presence of harmful substances in the soil, including chemicals, heavy metals, and pesticides. Industrial activities, improper waste management, and the excessive use of chemical fertilizers and pesticides contribute to soil pollution. This type of pollution poses a serious threat to agricultural productivity, decreasing soil fertility, and compromising food security.

The consequences of soil pollution go beyond agriculture. Contaminated soil can directly impact human health by transferring toxic substances to crops and subsequently to humans through the food chain. Moreover, it leads to environmental degradation, making the land unsuitable for habitation and disrupting the delicate balance of ecosystems.

Environmental pollution, in its various forms, is an ever-increasing threat that demands immediate attention and action. The impacts of air, water, and soil pollution are extensive and have multifaceted consequences for our health, the environment, and the sustainability of natural resources. Recognizing the severity of this issue is the first step towards adopting sustainable practices, implementing effective policies, and fostering a collective responsibility to protect our environment for future generations.

Long Essay on Pollution 500 Words in English

Below we have given a long essay on Pollution of 500 words is helpful for classes 7, 8, 9 and 10 and Competitive Exam Aspirants. This long essay on the topic is suitable for students of class 7 to class 10, and also for competitive exam aspirants.

With the rise of the industries and the migration of people from villages to towns in search of employment, there has been a regular increase in the problem of proper housing, and unhygienic conditions of living has led to rise in factors which increase pollution.

The mad rat race among countries of the world to compete against each other in the index of development has harmed the health of the people itself. Progress in agriculture and industry is taken as an indicator of development. This resulted in the exploitation of natural resources in a reckless manner. Thus, pollution has been an inevitable gift of industrialisation and urbanisation.

The growth of industries has given rise to the problem of proper disposal of waste material of the industries. Many a times, the waste products of these industries contain poisonous elements which if disposed without being properly treated, pollute the rivers and other water bodies. Thus, we face the problem of water pollution.

The poisonous water and waste product of the factories mingles with the water bodies and poisons them. Resultantly, the aquatic life gets affected. Fish die, disturbing the ecological balance. The water too is rendered useless which can neither be used for drinking or washing. This also results in the reduction of the area of water bodies. Such a situation arises when non-degradable products are dumped on fallow land or on the banks of rivers and sea shores.

Waste materials such as plastics, polythene, bottles etc cause land pollution and render soil infertile. Moreover, dumping of dead bodies of men and animals, washing of clothes and utensils too add to the problem. In recent surveys, Sabarmati river in Gujarat, Yamuna and Ganga rivers have been found to be excessively polluted. Yamuna has been described as an ‘Open Drain’.

Another major problem of pollution is the air that we breathe in being polluted by the smoke pouring out of chimneys and automobiles. No doubt, air pollution takes place even by volcanoes, cyclones, forest fires etc. But human activities are more responsible for causing air pollution. Gases like CO 2 , CO, SO 2 , are emitted which mix with air and cause great harm to the human body, flora and fauna.

The use of dry farm waste, dry grass, leaves and coal used as domestic fuels in our villages also produce harmful gases. Acid rain occurs due to excess of SO 2 in the air. The most tragic incident of air pollution is the Bhopal Gas Tragedy when the dangerous Methyl Isocyanide was emitted from Union Carbide Fertiliser Factory in 1984 which killed thousands of men, women and children, and rendered thousands of others handicapped.

Fire crackers, nuclear explosions, air conditioners, refrigerators, organic solvents, pesticides etc also contribute significantly in polluting air. Air pollution not only causes various kinds of allergies, respiratory problems and other health problems but also affects the vegetation, animal life and the environment. The soot which contains high concentration of hydrocarbons proves very harmful for monuments like the Taj Mahal.

Another very subtle form of pollution is noise pollution. Technology has given us comfort along with a cacophony of harsh and unharmonious sounds. This problem is extremely severe in big towns and cities. The maddening horns, loud speakers, music systems etc cause metabolic, hearing and other kinds of disorders. Noise pollution may also lead to a nervous breakdown or madness. Uttar Pradesh Pollution Control Board (UPPCB) recently revealed that even silence zones, such as hospitals, schools and residential areas are suffering from high decibels of sound.

Thus, we see that there are various kinds of pollutions which need to be checked in time. Problems like ozone depletion, global warming, greenhouse effect, change in climatic and weather conditions, melting of glaciers etc have arisen due to pollution. Strict and serious measures should be taken to control it. Industrial waste should be properly treated in special treatment plants before letting it flow into the water bodies or dumping it. The pollution department of Farrukhabad issued directives to close all textile dyeing units, polluting the Ganga river.

Use of organic manures should be encouraged instead of chemical fertilisers to prevent soil pollution. Planting of trees should be encouraged and cutting down of green trees should be strictly checked. Unleaded petrol should be used in vehicles. The directions of the Supreme Court to manufacture cars as per Euro I and Euro II norms should be strictly enforced.

Short Essay on Pollution 200 Words in English

Below we have given a short essay on Pollution is for Classes 1, 2, 3, 4, 5 and 6. This short essay on the topic is suitable for students of class 6 and below.

Industries should have proper emission systems and should conform to the laws in order to ensure safety of the people living in residential areas around. Strict laws should be legislated and enforced regarding the keeping of our sea shores and river banks clean. For example, Himachal Pradesh was the first state to ban plastic and polythene bags, to save the fragile ecology of Himalayas. But the law exists only on paper.

The horns of automobiles should be checked as per the limits prescribed by law. Loud speakers music system etc should be strictly prohibited after ten at night and vehicles should not be allowed to play their stereos at high volume.

The Government, after launching online green clearance systems for industrial and infrastructure projects, now will monitor treatment of industrial effluents and emissions, in a similar manner, by using online systems. The purpose is to bring transparency and facilitate real-time analysis of waste discharge.

The Government should also try to educate people about various kinds of pollution and create public awareness. People should be involved in helping to reduce and control pollution. Moreover, punishments should be strictly given in case of violation of any environmental law so that such people learn a lesson. Until we all get serious and resolve to make our planet a better place to live in, humanity stands amidst grave danger of perishing and being destroyed due to the severe and increasing problem of pollution. Franklin D Roosevelt, former American President, said the same about pollution:

“A nation that destroys its soils, destroys itself.”

Air pollution is a most serious problem of the current time all over the world, especially in large cities, because of the huge level of industrialization. The release of such air pollutants in heavy concentrations such as smog, particulates, solid materials, etc., are getting settled over the city, causing air pollution and health hazards. Many dirty wastes are produced by people daily, especially in the big cities polluting the whole atmospheric air to a great extent.

The release of gaseous pollutants from burning fuel of motor vehicles, industrial processes, burning of garbage, etc., are contributing to the air pollution. Some natural pollutants like pollen, dust, soil particles, natural gases, etc., are also sources of air pollution.

Air Pollution Essay 150 words

is the mixing of harmful substances into the atmosphere fresh air causing huge levels of damage, human health disorders, reducing the quality of life, etc. Air pollution is increasing daily because of the increasing number of industries. Such polluted air never remains in one place but spread to the whole environment and affects people’s lives all through the world. Death rates of human beings have increased because of an increased variety of diseases. The polluted air we breathe every moment causes lung disorders and even lung cancer, thus affecting the health of other body organs.

Air pollution continuously damages the whole ecological system and affects the lives of plants and animals. It has reached a critical stage and affected the whole atmosphere by allowing more harmful radiations from the sun to the earth. Again polluted air acts as a better insulator that prevents heat from escaping back into space.

Air Pollution Essay 200 words

Air pollution is one of the main environmental issues nowadays. There are many reasons behind regularly increasing this air pollution. Most air pollution is caused by automobiles, transport means, industrialization, growing cities, etc. The release of several harmful gases or dangerous elements from such sources is causing whole atmospheric air pollution. The ozone layer is also getting affected too much by air pollution, which causes serious disturbances to the environment. The increasing need of the ever-growing human population is the main cause of pollution. Daily human being activities causing dangerous chemicals to release, making the atmosphere dirtier than ever and forcing climate change negatively.

The industrialization process releases harmful gases, particles, paint, and batteries containing lead; cigarettes release carbon monoxide, and transport means release CO2 and other toxic substances into the atmosphere. All the pollutants are in contact with the atmosphere, destroying the ozone layer and calling harmful sun rays to the earth. In order to reduce the level of air pollution, we should bring some huge changes to our habits on a daily basis. We should not cut trees, use public transportation, avoid spray cans, and do so many activities to reduce the effects of air pollution.

Air Pollution Essay 250 words

Air pollution is the mixing of foreign substances into the whole atmospheric air. Harmful and toxic gases emitted by industries and motor vehicles cause huge damage to living organisms, whether plants, animals, or human beings. Some of the natural and various human resources are causing air pollution. However, most air pollution sources stem from human activities like burning fossil fuels, coal, and oil and releasing harmful gases and substances from factories and motor vehicles. Harmful chemical compounds like carbon dioxide, nitrogen oxides, carbon monoxide, sulfur dioxide, solid particles, etc., are getting mixed into the fresh air. The level of air pollution has increased greatly because of the 690% increase in damaging pollutants because of the expanded need for motor vehicles in the last century.

Another source of air pollution is the decomposition of garbage in landfills and the disposal of solid wastes emitting methane gas (dangerous to health). The rapid growth of population, industrialization, and increased use of automobiles, airplanes, etc., have made this issue a serious environmental problem. The air we breathe every moment is full of pollutants going to our lungs and whole body through blood, causing uncountable health problems. Therefore polluted air is causing damage to plants, animals, and human beings in many direct and indirect ways. If the environmental protection policies are not followed seriously and strictly, the increasing level of air pollution may increase to one million tons annually in recent decades.

Air Pollution Essay 300 words

When the fresh air gets polluted by means of dust, toxic gases, smoke, motor vehicles, mills, factories, etc. called air pollution. As we all know that fresh air is the most important element of a healthy life, we need to think that what happens if the whole atmospheric air gets dirty. First, air pollution is a matter of great regret for the whole human fraternity. Some of the big reasons for air pollution are poisonous fertilizers, insecticides, and pesticides in the agricultural sectors by innocent farmers to increase crop production. Released chemicals and hazardous gases (ammonia) from fertilizers are getting mixed into the fresh air and causing air pollution.

The burning of fossil fuels such as coal and petroleum and other factory combustibles are the major causes of air pollution. A variety of smoke emissions from the automobiles, such as cars, buses, motorcycles, trucks, jeeps, trains, airplanes, etc., are also causing air pollution. An increasing number of industries are causing the release of toxic industrial smokes and harmful gases (like carbon monoxide, organic compounds, hydrocarbons, chemicals, etc.) from the factories and mills to the environment. Some indoor activities of the people, like innocent use of cleaning products, washing powders, paints, etc., emit various toxic chemicals into the air.

The ever-increasing level of air pollution also enhances its harmful effects on the health of living beings. Air pollution is causing global warming to increase because of increasing atmospheric temperature due to the increasing level of greenhouse gases. Such greenhouse gases again cause greenhouse effect and force sea levels to increase, glaciers to melt, weather to change, climate to change, etc. Increasing air pollution is causing many lethal diseases (cancer, heart attack, asthma, bronchitis, kidney diseases, etc.) and death. Various important animal and plant species have been destroyed completely from this planet. The increasing level of harmful gases in the environment is causing the occurrence of acid rain and depleting the ozone layer.

Air Pollution Essay 400 words

The increasing concentration of harmful and toxic materials in the fresh air of the atmosphere is causing air pollution. Various foreign particles, toxic gases, and other pollutants released from various human activities are affecting the fresh air, which has an adverse effect on living beings like humans, animals, and plants. Air pollution levels depend on the type and amount of pollutants released from various sources. Topographical and meteorological conditions are increasing the spread and concentration of pollutants. Therefore variety of raw materials used in the manufacturing process in industries is increasing the type and quantum of emissions of harmful gases. Increasing population density is demanding the need for more industrialization, which ultimately causes air pollution.

Air Pollutants like harmful liquid droplets, solids particulates, and toxic gases (oxides of carbon, halogenated and non-halogenated hydrocarbons, nitrogen and sulfur gases, suspended inorganic particulate matters, inorganic and organic acids, bacteria, viruses, insecticides, etc.) which are generally not the constituents of fresh air are very hazardous to the plant and animal life. There are two types of air pollution sources which are natural sources and man-made sources. Some natural sources of air pollution are volcanic eruptions, volcanoes (ashes, carbon dioxide, smokes, dust, and other gases), deflation of sands, dust, salts spray from seas and ocean, soil particles, storms, forest fires, cosmic particles, rays, the bombardment of asteroid materials, comets, pollen grains, fungal spores, viruses, bacteria, etc.

However Man-made sources of air pollution are industries, agriculture, power plants, automobiles, domestic sources, etc. Some of the air pollutants from man-made sources are smoke, dust, fumes, particulate matter, gases from the kitchen, domestic heating, emissions from different vehicles, use of insecticides, pesticides, herbicides, and the heat created from power plants, smokes, fly ash, etc. Because of the increasing number of air pollutants, it has divided into two types: primary and secondary pollutants. Primary pollutants directly affect the fresh air and emitted from smoke, ash, dust, fumes, mist, spray, inorganic gases, carbon dioxide, carbon monoxide, sulphur dioxide, hydrogen sulphide, ammonia, nitric oxide, and radioactive compounds. Secondary pollutants indirectly affect the air by chemical interactions with the primary pollutants and other atmospheric constituents such as sulphur-trioxide, ozone, hydrocarbons, nitrogen dioxide, etc.

The get-together effort of human beings all over the world may help in controlling the level of air pollution. Establishment of industrial estates should away from residential areas, motivate use of tall chimneys instead of small, promote the use of high-temperature incinerators. However use of non-combustive sources of energy, promote the use of non-lead antiknock agents in the gasoline, promote re-plantation and so many positive efforts.

Air pollution essays given above useful to range of students studying in classes 1 to 10, etc. You can select any of them according to your need and requirement. Also you can use in an exam or essay writing competition at any event. Apart from an essay on air pollution, you can get other related essays and related information such as:

Biden-Harris Administration Finalizes Strongest Ever Greenhouse Gas Standards for Heavy-Duty Vehicles to Protect Public Health and Address the Climate Crisis While Keeping the American Economy Moving

March 29, 2024

WASHINGTON – Today, March 29, the U.S. Environmental Protection Agency announced final national greenhouse gas pollution standards for heavy-duty vehicles, such as freight trucks and buses, for model years 2027 through 2032. The standards will avoid 1 billion tons of greenhouse gas emissions and provide $13 billion in annualized net benefits to society related to public health, the climate, and savings for truck owners and operators. The final standards will also reduce dangerous air pollution, especially for the 72 million people in the United States who live near truck freight routes, bear the burden of higher levels of pollution, and are more likely to be people of color or come from low-income households.

The “ Greenhouse Gas Emissions Standards for Heavy-Duty Vehicles - Phase 3” standards will provide greater certainty for industry, while catalyzing private investment, supporting U.S. manufacturing jobs in advanced vehicle technologies, and invigorating and strengthening the U.S. economy. Over the next decade, these final standards, paired with President Biden’s historic Investing in America agenda and investments in U.S. manufacturing, will set the U.S. heavy-duty sector on a trajectory for sustained growth.

EPA’s latest modeling shows that the final standards will result in greater reductions of pollution than the proposed rule, while providing more time and flexibility for manufacturers to develop, scale, and deploy clean heavy-duty vehicle technologies. The 1 billion tons of greenhouse gas emissions avoided by these standards is equivalent to the emissions from more than 13 million tanker trucks’ worth of gasoline. With this action, the Biden-Harris Administration is continuing to deliver on the most ambitious climate agenda in history while advancing a historic commitment to environmental justice.

“In finalizing these emissions standards for heavy-duty vehicles like trucks and buses, EPA is significantly cutting pollution from the hardest working vehicles on the road,” said EPA Administrator Michael S. Regan. “Building on our recently finalized rule for light- and medium-duty vehicles, EPA’s strong and durable vehicle standards respond to the urgency of the climate crisis by making deep cuts in emissions from the transportation sector.”

“EPA’s standards complement President Biden’s unprecedented investment in our workers and communities to reduce harmful emissions, while strengthening our manufacturing capacity for the transportation technologies of the future,” said President Biden’s National Climate Advisor Ali Zaidi. “By tackling pollution from heavy-duty vehicles, we can unlock extraordinary public health, climate, and economic gains.”

Trucks and other h eavy-duty vehicles are vital to the United States economy, transporting goods and freight and providing services for industry, transit, and other sectors. At the same time, heavy-duty vehicles account for 25 percent of all greenhouse gas emissions from the transportation sector, which is itself the single largest source of greenhouse gas emissions in the United States. Greenhouse gas emissions are the primary driver of climate change and its impacts, including more severe heat waves, drought, sea level rise, extreme climate and weather events, coastal flooding, and catastrophic wildfires .

“Today’s announcement demonstrates that a zero-emission heavy-duty vehicle future is not only achievable, but more essential than ever given the disproportionate rate of greenhouse gas emissions from buses and trucks,” said Senator Alex Padilla (D-CA). “This historic rule reflects California’s leadership and heeds my consistent calls to implement a strong HDV emissions rule that will transform our transportation sector and safeguard clean air for all, including for disadvantaged communities in freight corridors. I also applaud the Biden Administration for recently launching a whole-of-government strategy to deploy the zero-emission heavy-duty infrastructure needed to make this transition a success.” 1

“The American Lung Association is pleased to support the new cleaner trucks standards,” said Paul G. Billings, National Senior Vice President, Public Policy, American Lung Association. “Today’s rule will improve the air we breathe and curb the pollution that is driving climate change. This rule is the capstone of the Clean Trucks Plan. The strong standards finalized today build on the 2023 rule to address oxides of nitrogen and last week’s multipollutant rule that will clean up light-and medium-duty vehicles. The result will be cleaner air and better health, especially in communities with heavy truck traffic nearby.”

“Sierra Club is pleased that the EPA has finalized the federal heavy-duty vehicle standards, which will help cut emissions from large polluting trucks and buses,” said Katherine García, Director of the Sierra Club’s Clean Transportation for All campaign. “The new standards reflect Congress' long standing demand for healthy air along with its recent historic investments in getting cleaner vehicles on our roads, corridors, and ports. Together, they are a game changer. With the climate crisis underway and many of our communities facing unprecedented fires, droughts, and floods, it’s crucial that truck manufacturers get into the fast lane with zero-emission trucks to deliver the climate, health, and economic benefits we deserve.”

"Hip Hop Caucus is encouraged by EPA's new federal emissions standards for trucks, which will reduce the harmful air pollution that disproportionately affects Black, Brown, Indigenous and low-income communities near ports, roadways and highways,” said Russell Armstrong, Senior Director of Campaigns and Advocacy at the Hip Hop Caucus. “This is a meaningful step in the right direction. We will continue to work with EPA to make sure that clean vehicles are accessible and affordable for all.”

Heavy-Duty Vehicle Greenhouse Gas Standards

Today’s “Phase 3” standards build on EPA’s Heavy-Duty Phase 2 program from 2016 and maintain that program’s flexible structure, which is designed to reflect the diverse nature of the heavy-duty vehicle industry. The standards are technology-neutral and performance-based, allowing each manufacturer to choose what set of emissions control technologies is best suited for them and the needs of their customers. Available technologies include advanced internal combustion engine vehicles, hybrid vehicles, plug-in hybrid electric vehicles, battery electric vehicles, and hydrogen fuel cell vehicles. These new standards apply to heavy-duty vocational vehicles (such as delivery trucks, refuse haulers, public utility trucks, and transit, shuttle, and school buses) and tractors (such as day cabs and sleeper cabs on tractor-trailer trucks).

Relative to the proposal, EPA’s final rule provides more time in the early model years of the program for the development of vehicle technologies and deployment of charging and refueling infrastructure. The final rule also includes flexibilities that will assist manufacturers in meeting the standards in the early years of the program while preserving incentives for early adoption of advanced technologies.

EPA received extensive feedback on the proposed rule, including over 175,000 public comments, testimony at public hearings, and engagement with stakeholder groups. The final standards were informed by the best available data and information in the public record and rigorous technical assessments, including consideration of the extensive public input EPA received in response to the proposed rulemaking. 

Prioritizing Public Health and Climate Benefits

Pollution from heavy-duty vehicles contributes to climate change and can exacerbate serious health issues such as respiratory and heart ailments, especially for the 72 million people in the United States who live close to truck freight routes and are more likely to be people of color or come from low-income households. Today’s final heavy-duty greenhouse gas standards complete EPA’s Clean Trucks Plan for reducing greenhouse gas emissions and other harmful air pollutants (including nitrogen oxides (NO x ), particulate matter (PM), and air toxics) from heavy-duty vehicles through a series of rulemakings. These rules include today’s standards as well as (1) EPA’s recently finalized light- and medium-duty vehicle multipollutant standards for MY 2027-2032 (which covers Class 2b and 3 trucks), and (2) EPA’s December 2022 rule to control smog- and soot-forming emissions from heavy-duty engines and vehicles. The Clean Trucks Plan represents the most protective set of EPA regulations ever for the on-road sector, significantly reducing pollution, protecting public health, and responding to the urgency of climate change.

Savings and Customer Choice

There is a wide variety of trucks and other heavy-duty vehicles on the road, serving a diverse array of needs and customers. Today’s standards recognize the diversity of vehicle types and encourage further innovations in clean vehicle technology, enhancing options at the dealership that will also save customers, owners, and operators money through reduced fuel and maintenance costs. Under these new standards, the heavy-duty industry is expected to realize annualized savings of $3.5 billion compared to annualized costs of about $1.1 billion from 2027 through 2055.

After accounting for the vehicle purchase tax credits provided under President Biden’s Inflation Reduction Act, the typical buyer of new clean technology vocational vehicles and day cabs in 2032 when the standards are fully phased in will save money on the upfront cost of the vehicles and recoup any additional costs, such as the purchase and installation of vehicle charging equipment, in two to four years. The typical buyer of new clean technology sleeper cab will recoup the upfront cost of a vehicle in five years. A purchaser of a heavy-duty truck in 2032 – when the standards are fully phased in – could save between $3,700 and $10,500 on fuel and maintenance costs annually, depending on vehicle type.

Working with Stakeholders Throughout Phase 3 Implementation

EPA’s analysis finds that heavy-duty vehicle technologies, charging and refueling infrastructure, and supply chains will be available to support the final standards. At the same time, EPA has committed to actively monitor and track the technologies the heavy-duty vehicle manufacturers are developing and deploying, and the deployment of heavy-duty vehicle electric charging and hydrogen fueling infrastructure in order to ensure the successful implementation of the Phase 3 program.

EPA will consult with a wide range of stakeholders on an ongoing basis to learn from their experiences and gather relevant information and data. These stakeholders will include, at a minimum, trucking fleets and trucking trade associations; heavy-duty vehicle owner-operators; heavy-duty vehicle manufacturers; investor-owned utilities, public utilities, and electricity cooperatives; infrastructure providers and installers; state and local governments, communities with environmental justice concerns; and environmental and public health NGOs. In consultation with other agencies, beginning as early as 2026, EPA will issue periodic reports reflecting the collected information throughout the lead-up to and during the implementation of the Phase 3 standards. Based on these reports, the agency may decide to issue guidance documents, initiate a future rulemaking to consider modifications to the Phase 3 rule, or make no changes to the program.

In parallel to the Phase 3 rule, the Joint Office of Energy and Transportation and the Department of Energy, in collaboration with the Department of Transportation and the Environmental Protection Agency, recently announced the first-ever National Zero Emission Freight Corridor Strategy, an all-of-government action plan for deploying a world-class zero-emission freight network across the nation by 2040. The Strategy prioritizes high-traffic routes and freight hubs to catalyze four phases of public and private investment in heavy-duty zero-emission transportation, with a focus on reducing harmful emissions for the most affected communities.

Investing in America’s Clean Transportation Future  

The final standards align with and support the commitments and billions of dollars’ worth of investments from trucking fleets, vehicle manufacturers, and vehicle technology firms as they plan to increase the use or production of clean vehicle technologies in trucking and other heavy-duty fleets. These investments are resulting in a range of technologies with the potential for further significant reductions of greenhouse gas emissions from heavy-duty motor vehicles.

EPA recently announced the launch of the $3 billion Clean Ports Program to help tackle emissions from heavy-duty vehicles both in and out of U.S. port communities. Along with EPA’s long-standing Diesel Emissions Reduction Act (DERA) program which reduces harmful emissions from diesel engines , the new Bipartisan Infrastructure Law Clean School Bus Program, and an upcoming clean heavy-duty program to fund the replacement of existing Class 6 or Class 7 vehicles with clean technology vehicles, we are making changes in communities now to reduce emissions from the heavy-duty fleet. Together, these programs are offering billions of dollars in funding to replace older vehicles and engines with clean vehicle technology options.

As the EPA finalizes the rule, the Biden-Harris Administration is also investing funds in communities across America from the Bipartisan Infrastructure Law to promote clean transportation, including building a national network of EV chargers and alternative-fuel stations; ensuring domestic manufacturers have the materials they need to make EV batteries; and funding clean transit and clean school buses, with priority for underserved communities. In addition, funding through the Inflation Reduction Act will directly support the clean-vehicle transition through support for domestic battery manufacturing and clean vehicle purchases for owners, operators, and businesses.

For more information on the Phase 3 Final Rulemaking, please visit EPA’s Final Rule: Greenhouse Gas Emissions Standards for Heavy-Duty Vehicles – Phase 3 website . 

Here’s what other leaders are saying about the final rule:

Sean Waters, Vice President Product Integrity for Daimler Truck North America: “We thank the agency for addressing industry concern about the challenges of the early years of the rule and we remain committed to upholding the spirit of this regulation.  At Daimler Truck North America, it is our aspiration to offer only carbon-neutral new vehicles in the U.S. by 2039 and our comprehensive product portfolio of state-of-the-art trucks will ensure our customers can transition to greener transportation on the road ahead.  Ultimately, the successful transition of the commercial vehicle industry is dependent on the availability of reliable zero emission charging and refueling infrastructure and the ability to conduct business at a reasonable cost of ownership.  We appreciate the regulation’s recognition of this fact and look forward to working with the EPA as well as federal and state governments to deliver both.”

Senator Tom Carper (D-DE), Chairman of the Senate Environment and Public Works Committee: “Curbing emissions from heavy-duty vehicles is a win-win for the planet and public health. It supports the United States in reaching President Biden’s ambitious climate goals while cleaning up the air we breathe. Today’s rule will be especially critical for disadvantaged communities located near freight corridors that are overburdened by air pollution, as well as the millions of children who are currently riding dirty diesel buses to school each day. I commend the EPA for their continued work to build a clean transportation future for America.”

Representative Pete Aguilar (CA-33): “I am glad to see that the EPA’s new emission standards will drastically lower carbon emissions, reducing smog and pollution in the Inland Empire. Not only does this rule make crucial progress in combatting climate change, but it will also contribute to better health outcomes in our community and create more jobs in the clean energy sector. I look forward to working with the EPA on implementing these standards in our community and advocating in Congress for more clean energy solutions.”

Cynthia Williams, Global Director for Sustainability, Ford Motor Company : “The EPA’s new heavy-duty emissions rule is challenging, but Ford is working aggressively to meet the moment. Our industry is making important progress to reduce greenhouse gas emissions in both light- and heavy-duty vehicles. We also need policymakers to pair emission standards with incentives and public investment so that we can continue to deliver on the next generation of vehicles and for our nation to lead the future of this industry.”            

Neha Palmer, CEO and Co-Founder, Terawatt : “Fleet charging solutions providers like Terawatt are proud to be investing billions into infrastructure that supports electrification at scale. We look forward to continue working with fleets incorporating EVs to ensure that charging is available as trucks continue to hit the road — and initiatives that get EVs closer to cost parity with ICE vehicles are crucial. These standards, combined with the National Zero Emission Freight Strategy released earlier this month, gives the industry a coordinated pathway towards accelerated uptake of zero-emission vehicles."

Air pollution may trigger DNA modifications tied to Alzheimer’s disease

Fine particulate matter (PM2.5), a type of air pollutant, may contribute to Alzheimer’s disease risk by affecting DNA methylation patterns tied to neuroinflammation, according to NIEHS-funded research. Neuroinflammation, which is an immune response in the central nervous system, is a hallmark of Alzheimer’s disease.

Growing evidence indicates that PM2.5 is a risk factor for Alzheimer’s disease, but the underlying mechanisms are unclear. Results from human and animal studies suggest that changes in DNA methylation, which regulate gene expression, are associated with indicators of Alzheimer’s disease and PM2.5 exposure.

The researchers assessed DNA methylation in human postmortem brain tissues obtained from 159 donors who participated in the Emory Goizueta Alzheimer’s Disease Research Center brain bank program. They also estimated donors’ residential traffic-related PM2.5 exposure at one, three, and five years before death. Using a combination of analytical approaches, the team looked for differences in methylation patterns that could explain links between PM2.5 exposure and Alzheimer’s disease.

Differences at two methylation sites — cg25433380 and cg10495669 — were consistently associated with PM2.5 across all exposure timeframes. One of those sites, cg10495669, is connected to a gene that regulates inflammation. The team also identified 22 methylation sites that may underpin ties between PM2.5 exposure and indicators of Alzheimer’s disease. Several of those sites are located in genes responsible for neuroinflammation and related cell death. In addition, the researchers found links between PM2.5 exposure at the three-year window and methylation changes along a pathway important to life span.

The study is the first to show an association between PM2.5 exposure and varying methylation patterns in the human brain. Results should be verified with a larger sample size across more diverse stages of Alzheimer’s disease, according to the authors. (JL)

Heavy metal exposure linked to earlier menopause

Exposure to heavy metals may be linked to earlier menopause in middle-aged women, NIEHS-researchers reported. The study is the first to assess how metals affect levels of anti-Müllerian hormone (AMH) over time in women approaching menopause.

AMH is a marker of ovarian reserve, or the number of eggs remaining in the ovaries. Ovarian reserve and AMH levels naturally drop in the years leading up to menopause, called the menopausal transition period. A woman reaches menopause once she has gone 12 months without a menstrual period.

The team analyzed data from about 550 middle-aged women enrolled in the Study of Women's Health Across the Nation, a racially and ethnically diverse investigation of how the menopausal transition affects health. The researchers assessed the relationship between levels of arsenic, cadmium, mercury, and lead in urine and levels of AMH in blood in the 10 years leading up to the women’s last menstrual period.

Higher urinary concentrations of arsenic and mercury were associated with lower AMH at the final menstrual period. The top one-third of arsenic and mercury exposures were associated with 32% and 40% lower AMH levels, respectively, compared to the bottom one-third of exposures. During the menopausal transition period, women in the top one-third of cadmium and mercury exposures experienced faster rates of AMH decline — 9% and 7%, respectively — than women in the bottom one-third.

According to the authors, these results indicate that certain heavy metals may act as ovarian toxicants by depleting ovarian reserve in women approaching menopause. (MA)

Phthalate exposures associated with high numbers of preterm birth

Nearly 57,000 cases of preterm birth a year may be attributable to phthalate exposures, according to a study funded by NIEHS and others. Associated economic and medical care costs are an estimated $3.8 billion, highlighting a need for robust exposure prevention efforts.

The consequences of preterm birth include infant and childhood mortality; adverse psychological, behavioral, and educational outcomes in young adulthood; and cardiovascular disease and diabetes in later life. Phthalates — synthetic chemicals widely used in consumer products, such as vinyl flooring and personal -care items — have been implicated in preterm birth. However, little is understood about the potential effects of newer phthalates, such as diisononyl phthalate (DiNP) and diisodecyl phthalate (DiDP), used to replace di-2-ethylhexyl phthalate (DEHP) in food packaging.

Using data from the NIH Environmental influences on Child Health Outcomes (ECHO) Program for 1998-2022, the researchers studied associations between 20 phthalates and gestational age at birth, birthweight, and birth length for 5,006 mother-child pairs. They also investigated negative birth outcomes and financial costs that could be attributable to phthalate exposure.

Although DEHP exposure was associated with preterm birth, the replacement chemicals DiDP, DiNP, and di-n-octyl phthalate showed stronger associations. The team also estimated that 56,595 cases of preterm birth in 2018 could be attributed to phthalate exposures. For that year, lost economic productivity and additional medical care costs due to phthalate-induced preterm birth could have ranged from $1.6 to $8.1 billion.

The results suggest substantial opportunities for phthalate exposure prevention, according to the authors. They added their findings also show that DEHP replacements are not safer, indicating a need to regulate chemicals with similar properties as a class. (JL)

Moderate radon exposure associated with increased risk of stroke in women

Exposure to moderate levels of radon was associated with increased risk of stroke in middle-aged and older women, NIEHS-funded researchers reported. The findings add to limited research on how exposure to the radioactive gas affects stroke risk in women, who are more prone to strokes than men.

Rocks and soil naturally release radon, which can accumulate inside buildings by entering through small cracks. Although radon is a leading cause of lung cancer and is implicated in stroke, radon testing and mitigation tend to be less common than recommended in the U.S.

The researchers used data from nearly 160,000 women ages 50-79 when they joined the Women’s Health Initiative, a decades-long study of postmenopausal women in the U.S. They estimated exposure by linking each woman’s home address to federal data on radon levels, which they grouped into low-, middle-, and high-radon exposures. Using medical records and death certificates, they confirmed stroke outcomes in participants during the approximately 13-year follow-up.

Stroke risk was 6% and 14% greater among women living in middle and high exposure areas, respectively, compared to those with the lowest radon exposures. Notably, stroke risk was significantly elevated among women exposed to radon at mid-levels, which are below the recommended threshold for taking mitigation steps, according to the U.S. Environmental Protection Agency.

Overall, the results suggest a relationship between radon exposure and increased risk of stroke among women. According to the authors, confirmation of this trend in a more diverse population could extend the generalizability of these findings and help inform stricter radon action levels to protect public health.

Class 8 Chapter 18 – Pollution of Air and Water Important Questions with Answers

Q1: Name the chemicals which are used in refrigerators and air conditioners and damage ozone layer when released in air.

Ozone depletion in the upper atmosphere is caused by CFCs. CFCs are organic compounds that contain only carbon, chlorine, and fluorine and are formed as a volatile derivative of methane, ethane, and propane. Many CFCs have been used as refrigerants, propellants (for aerosols), and solvents.

Q2: Name any two sources which cause air pollution due to suspended particulate matter.

Suspended particulate matter (SPM) is a term used to describe fine solid or liquid particles that are scattered through the air as a result of activities such as combustion, industrial processes, or natural sources (like volcanic eruptions.)

The following are two sources of air pollution that may be caused by SPM:

a) Automobiles: Automobiles run on gasoline and diesel, which creates SPM that is suspended in the air.

b) Industrial activities: Mining, construction, and demolition of buildings all release SPM into the air. These activities produce a large amount of dust particles in the air, which are picked up by the wind and float around in the air.

Q3: Name two gases which are mainly responsible for acid rain.

Sulphur dioxide (SO 2 ) and nitrogen dioxide (NO 2 ) are gases that combine with water, oxygen, and other gases to generate acids such as sulphuric and nitric acid, which eventually lead to acid rain.

Q4: The quality of air at various locations is monitored regulary by government and other agencies. In what way can you use these data?

Government and other agencies monitor air quality at various areas on a regular basis. These statistics can be used to raise public awareness about air pollution. People can be made aware of which amounts are acceptable and which are not. These statistics can also be used to educate people about the Air Quality Index and what the numbers mean. As the AQI rises, so do the risks to public health.

Q5: Combustion of fossil fuels generates a lot of air pollution. Can you suggest any two alternative sources of energy which do not cause any pollution?

The combustion of fossil fuels produces a significant amount of pollutants in the air. These fuels emit hazardous fumes when they are burned. To minimize this effect, we can generate energy from alternative sources such as:

1) Solar energy

2) Wind energy

3) Hydroelectric energy.

Q6: Name any two water pollutants which are toxic for plants and animals.

Arsenic and lead, for example, are poisonous to both plants and animals. Arsenic accumulates in the bodies of plants and animals, causing deformities. Lead, on the other hand, produces morphological malfunction.

Short Answer Type Questions

Q1: A lot of dry leaves are collected in a school garden and are burnt every day. Do you think that it is right to do so? If not, what should be done to dispose off the dry leaves?

Burning dry leaves pollutes the air because hazardous pollutants such as carbon monoxide are emitted. Instead of burning them, they should be composted because it does not pollute the environment and acts as manure for plants and trees.

• The smoke produced by leaf burning can irritate your eyes, nose, and throat, and the carbon monoxide produced by burning leaves and embers can lower the amount of oxygen in your blood and lungs if you are exposed to it long enough.
• Coughing, wheezing, and other respiratory problems can result, and they can last for a long time.

Q2: The level of air pollution is higher at a busy traffic intersection. Why?

Throughout the day, many vehicles such as cars, buses, scooters, and other automobiles stop at major traffic intersections. Each vehicle emits a significant amount of hazardous and polluting gases. The polluted air is caused by suspended particulate matter suspended in the air around that place.

Q3: Fill in the blanks with the help of words given in bracket after each sentence.

(a) When air is contaminated by ________ substances which have a _______ effect on both the ________ and __________ is referred to as __________ . (air pollution, harmful, living, unwanted, non-living, pollutants).

Long Answer Type Questions

Q1: What do CFCs stand for? Name some devices where CFCs are used. Why CFCs are considered as pollutants?

CFCs stands for Chlorofluorocarbons

The gases used in electric equipment such as air conditioners and refrigerators are chlorofluorocarbons. CFCs are made up of the components “Chlorine, Fluorine, and Carbon.” CFCs are considered pollutants since they contribute to the ozone layer’s depletion.

Q2: Why is it advised that industries should switch over to cleaner fuels such as CNG and LPG in the Taj Mahal Zone in Agra?

Less clean fuels like petrol and diesel are polluting the air to the point that acid is forming, endangering the Taj Mahal’s attractiveness by turning the Taj’s white marble yellow due to acids like sulphuric and nitric falling on it.

Q3: It is said, “CO 2 contributes to global warming.” Explain.

CO 2 is a pollutant gas that contributes to air pollution and climate change. CO 2 is a gas that is used by plants and trees for photosynthesis, resulting in a reduction in carbon dioxide in the atmosphere in exchange for oxygen. However, as time passes, industrialization accelerates and trees are chopped at an alarming rate, resulting in an increase in carbon dioxide levels, which eventually leads to an increase in the trapping of heat on Earth alone, causing the planet’s temperature to rise at an alarming rate.

Q4: We should plant trees and nurture the ones already present in the neighbourhood. Why?

Afforestation, or the planting of more trees, is urgently needed. Pollution and global warming are both increasing over time. We need more and more trees to decrease global warming because plants use carbon dioxide to generate food for photosynthesis and release oxygen. As a result, as the number of trees grows, the impact of dangerous gases such as CO 2 on the ecosystem would diminish.

Plants help to keep soil from eroding. Plants help to keep groundwater clean. The more trees we plant, the more rain we will receive, and hence the more water we will be able to extract.

Q5: Explain the traditional way of purifying water to make it fit for drinking.

There were no aqua guards or purifiers because there was not much machinery back then. However, the water was cleansed in a more convenient and reliable manner, using traditional processes. They are the following:

Filtration : This approach employs the use of a filter or filter rods. A typical domestic filter is the candle type filter.

Boiling : By raising the temperature of the water, all germs and pollutants in the water are killed.

Chlorination is the process of adding chlorine to water in the form of tablets or bleaching powder.

Q6: How can we reduce, reuse and recycle water?

Water consumption can be reduced by doing the following:

• Close the tap while brushing your teeth and only open it when absolutely essential. Change the tap or save the water from the leaky tap.
• When bathing, washing clothing, or doing dishes, don’t waste water unnecessarily.

Water can be reused in the following ways:

• Wash floors with the water filtered out by ROs.
• Water your plants with the same water you use to wash your fruits and veggies.

Water can be recycled in the following ways:

• Dirty water should be purified using filtration and other technologies.

Q7: Read the paragraph and answer the questions following it.

Water is essential for life. Without water, there would be no life. We usually take water as granted for its purity, but we must ensure the quality of water. Pollution of water originates from human activities. Through different paths, pollution reaches to groundwater. Easily identified source or place of pollution is called a point source, e.g.– municipal and industrial discharge pipes, where pollutants enter the water source. Non–point sources of pollution are those where a source of pollution can not be easily identified, e.g.– agricultural runoff, acid rain etc.

(i) How do you classify the various sources of water pollution?

(ii) What are the point sources of water pollution?

(iii) Name any two non-point sources of water pollution.

(i) There are two types of water contamination sources: point sources and non-point sources.

(ii) Point sources of water pollution are easily recognisable sources or locations of contamination, such as factories, power plants, and so on.

(iii) Non-point sources of water pollution include agricultural run-off and acid rain.
