Essay on Air Pollution-Introduction:

The air we breathe was once pure and fresh. However, due to advances in automation and the concentration of toxic gases in the environment, air is becoming more toxic day by day. In addition, these gases are the cause of many respiratory and other respiratory illnesses. In addition, rapidly increasing human activity, such as fossil fuel burning and deforestation, is a major cause of air pollution.

How Air Gets Polluted?

Fossil fuels, firewood, and others we burn produce oxides of carbon that are released into the atmosphere. In the past, there were many trees that could easily filter the breathing air. However, as the demand for land increased, people began to cut down trees, leading to deforestation. This eventually reduced the ability of the tree to filter. Moreover, in recent decades, the number of fossil fuel vehicles has increased rapidly and the number of pollutants in the atmosphere has increased. This is more harmful to human health.

What are Pollutants?

  • Primary air pollutants are pollutants that are released directly into the atmosphere. They are called SPMs and mean suspended particulate matter. For example, smoke, dust, ash, sulphur oxides, nitrogen oxides, radioactive compounds.
  • Secondary pollutants are pollutants produced by the chemical interactions between air components and primary pollutants. For example, smog (smoke, fog, etc.), ozone, etc.
  • The main gaseous air pollutants include carbon dioxide, hydrogen sulphide, sulphur dioxide and nitrogen sulphite.
  • Natural sources include volcanic eruptions, forest fires and dust storms.
  • Artificial sources These include gases. It is discharged from automobiles, industry, garbage and incinerators of brick kilns.

Causes of Air Pollution:

Causes include burning fossil fuels and firewood, volcanic eruptions, factory smoke, wildfires, bombings, asteroids, CFCs (chlorofluorocarbons), and carbon oxides. There are also other air pollutants such as industrial and agricultural waste, power plants, household chimneys and nuclear-fired power plants.

Green House Effect:

The greenhouse effect is a way in which heat is trapped by “greenhouse gases” near the surface of the earth. The gas that traps these heats can be thought of as a blanket that wraps around the earth, keeping it warmer than it would be without them. Greenhouse gases include carbon dioxide, methane, nitrogen oxides and water vapor. (Water vapor that physically or chemically reacts to temperature changes is called “feedback.”) Scientists have discovered that the warming effect of carbon dioxide helps stabilize the Earth’s atmosphere. Removing carbon dioxide destroys the greenhouse effect on the ground. Without carbon dioxide, the surface of the earth would be about 33 ° C (59 ° F) lower.

causes of air pollution

Greenhouse gases are naturally occurring and are part of our atmospheric composition. For this reason, the Earth is sometimes referred to as the “Goldilocks” planet. The condition is not too hot, not too cold, and is just right for life (including us) to thrive. Part of the reason that makes the Earth so accessible is its natural greenhouse effect, which keeps the Earth at a friendly 15 ° C (59 ° F) on average. But for the past century or so, humans have disrupted the Earth’s energy balance, primarily by burning fossil fuels that add carbon dioxide to the air. Carbon dioxide levels in the Earth’s atmosphere have risen steadily over decades, trapping additional heat near the Earth’s surface, leading to elevated temperatures.

Effects Of Air Pollution On Health:

Even healthy people can experience the health effects of polluted air, such as respiratory irritation and dyspnoea during exercise and outdoor activities. The actual risk of adverse effects depends on current health, the type and concentration of pollutants, and the duration of exposure to polluted air.

  • High pollution levels can cause imminent health problems such as:
  • Exacerbation of cardiovascular and respiratory illness.
  • Extra strain on the heart and lungs.
  • Impacts on polluted air can have lasting health effects.

The most vulnerable to serious health problems from air pollution are Person with heart disease, coronary artery disease, congestive heart failure, asthma, pulmonary emphysema, chronic obstructive pulmonary disease (COPD) and other lung diseases,  Pregnant women, Elderly and under 14 years old, Children and Athletes doing intense outdoor exercises.

Effects of Pollution on Health

Methods to Reduce Air Pollution:

1. Using Public Transport:

Using public transport is a short way to reduce air pollution, as it uses less fuel and energy and is useful for carpooling. In addition to reducing fuel and gas emissions, using public transportation can also help save money.

2. Turn off the lights when not in use:

The energy consumed by lights also contributes to air pollution, so you can save energy by using less power. Use energy-saving fluorescent lights to help the environment.

3. Reuse, Reduce and Recycle:

The concept of Reuse, Reduce and Recycle not only saves resources and uses them legally, but also helps reduce pollutant emissions and thus helps air pollution. Recycled products also require less energy to make other products.

4. No to plastic bags:

The use of plastic products can be very harmful to the environment as they take longer to decompose due to the oily material. Using a paper bag instead is a better alternative as it is fragile and recyclable.

5. Reduction of forest fires and smoking:

Garbage collection and burning in the dry season, or burning of dry leaves, is a major cause of air pollution. In addition, smoking causes air pollution, with obvious health consequences and deterioration of air quality.

6. Use of fans instead of Air Conditioners:

The usage of Air Conditioners takes a lot of energy and emits a lot of heat which is hazardous for the environment. Air conditioners also take a lot of power and energy to work as compared to fans.

7. Use filters for chimneys:

Emissions from fireplaces in homes and factories are extremely dangerous for air pollution and seriously affect air quality. The use of filters should be used at least if it is not possible to reduce consumption, which will help reduce the effect of harmful gases absorbed in the air.

8. Avoid usage of Fire crackers:

Unfortunately, the use of Fire crackers at festivals and weddings is one of the biggest causes of air pollution, creating a layer of smoke that is extremely hazardous to your health. Therefore, non-cracker practice should be taken.

9. Avoid using of products with chemicals:

Products that use chemicals or have strong odours such as paints and perfumes should be rarely used or absent. An alternative may also be to use products with low chemical and organic properties.

10. Implement Afforestation:

Last but not least, plant and grow as many green plants and trees as possible. The practice of growing trees has many benefits for the environment and helps release oxygen.


To sum up, we can say that the air we breathe is becoming more and more polluted. The largest contributor to the increase in air pollution is due to fossil fuel generation of nitric and sulfuric oxides. But, humans have taken this issue seriously and are working diligently to undo the problem they have created.

Frequently Asked Questions (FAQs):


Air pollution is all around us. Most people in the world live in areas with high levels of air pollution. It harms human health and well-being, reduces quality of life, and can negatively impact the economy. These impacts also affect the most vulnerable people and communities.

Air pollution is the largest environmental risk to public health in the world. People everywhere are exposed to air pollution, at work, while traveling and at home. According to the World Health Organization (WHO), exposure to household and ambient (outdoor) fine particulate air pollution causes around 7 million premature deaths each year, and is the leading cause of death. a significant amount of disability for people living with illnesses caused by air pollution.

Air pollution is a solvable problem, and the richest countries have significantly improved their air quality over the past decades. But air pollution is disproportionately affecting people in low- and middle-income countries.

In many developing countries, reliance on wood and other solid fuels, such as raw coal for cooking and heating, and the use of kerosene for lighting, increases indoor air pollution. , harmful to the health of those in contact. It is estimated that more than 2.7 billion people depend on these fuels. Most of the impacts are felt in parts of Asia and sub-Saharan Africa, where the burning of biomass for cooking is particularly common.


Air pollution comes from many different sources, both natural and anthropogenic (man-made). Natural sources include volcanic eruptions, sea spray, ground dust, natural vegetation fires, and lightning. Some of the more common man-made sources include power generation, transportation, industry, residential heating and cooking, agriculture, solvent use, oil and gas production, waste incineration and build. Some sources, such as forest and savanna fires and wind-blown mineral dust, occur naturally but are aggravated by human activities.

For a large portion of the world’s population, human activities are responsible for most of the air pollution they are exposed to.

Different pollutants have different sources. In cities, air pollution originates both within and outside city limits, with some cases requiring long distance travel. Major urban sources include vehicles, gas, coal and charcoal burning, firewood for cooking and heating, and industrial sources that remain within cities. Many large industrial sources, such as cement plants, steel mills and power generation, are located far from cities, but still contribute significantly to urban concentration, as they are transported long distances. by air. Emissions from the oil and gas and marine industries can also travel great distances.


It remains unresolved in any region, but there have been significant reductions in emissions and pollutant concentrations in many European countries, as well as in the United States, Canada and Japan. where regular policies, regulations and monitoring systems have been implemented. place.

One of the most famous examples is London, where some of the worst pollution levels, earlier than other cities, could peak in 1900. Since then, air quality in the UK has has improved markedly. Particulate air pollution levels fell by more than 97 percent between 1900 and 2016. Other cities and regions have also dropped significantly thanks to similar policies. However, this does not mean that air pollution has been solved. In London, PM2.5 is still above WHO air quality standards.

Mexico City is another example of how cities have dramatically reduced their air pollution. The city suffered from a very serious ozone (O₃) pollution problem in the 1980s. Since peaking in 1989, O₃ concentrations have dropped by two-thirds in 2015 – still high enough to have effects. important to health, but still greatly reduced.

These declines show that pollution of air is a problem we know how to solve and that policies and technologies are needed to achieve cleaner air. In many countries, air quality has improved as countries have become richer. This means that unlike in the past, where air pollution was seen as an inevitable cost of economic growth, reducing pollution of Air has no effect on economic growth. It is effectively decoupled from wealth creation.
