Air Pollution Control

If you take a look at the causes of air pollution, you will realize that humans are primarily responsible for air pollution. The growing industrialization has positive and negative impacts on mankind and the environment. Also, the increasing rate of environmental pollution is one of the significant drawbacks that we are facing, resulting from our deeds. Before talking about the control of air pollution, we will have to understand their meaning.

Air Pollution Definition

Air pollution means contamination of air, water, or soil by any substance that is harmful to the living organisms. It’s like an introduction or release of a toxic substance into the environment, that can harm the elements in the environment. The pollution can take place because of the natural (such as volcanic eruption), and man-made reasons. But nowadays, it’s the man-made reasons that are causing more pollution than natural ones. From the increasing number of vehicles to ever-growing industrial wastages in the form of air or water, each contributes to air pollution in some way.

What is Air Pollution?

The air pollution definition says that when any physical, chemical or biological change takes place in the air and contaminates it, then it is called air pollution. The contamination of air can be caused due to many factors such as poisonous or harmful gases, smoke, fog, smog, dust, etc. the air pollution affects both the plants as well as animals. 

Types of Air Pollutants

The air pollutants are divided as primary and secondary pollutants. Pollutants are those substances that cause air pollution.

Primary Pollutants:

The primary pollutants responsible for air pollution are the ones that directly cause air pollution. These include harmful gases such as sulfur dioxide coming from the factories.

Secondary Pollutants:

The secondary pollutants are formed by the process of intermixing or intermingling of primary pollutants. The smog, which is a combination of fog and smoke, is a secondary pollutant.

Causes of Air Pollution:

To prevent the pollution of air around, you have to understand the causes of air pollution at first. The main causes are – 

Burning of Fossil Fuels:

 The fossil fuel emits harmful gases such as sulfur dioxide and carbon monoxide into the air.


The emission  of harmful gases is caused by the excessive use of automobiles.

Agricultural Activities: 

Various processes taking place during agricultural activities such as emission of ammonia, overuse of insecticides, pesticides, and fertilizers. 

Factories and Industries:

Emission of harmful gases and chemicals into the air by the increasing industrial activities. 

Mining Activities:

Increasing emission of harmful substances through mining activities. 

Domestic Resources:

Effects of domestic sources such as the use of chemical paints and overuse of air conditioners.

Effects of Air Pollution:

The air pollution information shows that increasing air pollution can have an adverse effect on plants, animals, and humans. 


Air Pollution can lead to increasing diseases like throat infections and lung cancer in humans.

Global warming: 

Air Pollution can increase the amount of global warming as the temperature of the earth will keep rising with the emission of harmful gases. 

Acid rain: 

When water droplets combine with harmful chemicals and pollutants, it will lead to acid rain.

Ozone layer Depletion: 

All this will eventually lead to depletion of the ozone layer that protects us from harmful UV sun rays.

Thus, we have to work on the prevention of air pollution.

Effects on Animals:

Increasing air pollution affects animals and aquatic life, leading them to stray and wander for food. Many of the animals are on the verge of extinction because of this.

Air Pollution Control:

It is not easy to control air pollution, but it will require some simple steps like:

Avoid Using Vehicles:

Prefer using public transport as it will reduce the emission of CO into the air. The availability of carpools can help in the reduction of vehicles which in turn reduces the pollution. Prefer walking or cycling to nearby places and many such.

Energy Conservation:

Use energy-efficient electrical devices at the workplace and home place. You can keep your lights switched off when not in use. The electrical appliances should be checked on a regular notice period so that it won’t affect the conservation.

Use of Clean Energy Resources

It will help to reduce the pollution level. Instead of using fossil fuels, we can use the natural resources to produce energy like Solar Energy, Wind Energy, etc.

FAQ (Frequently Asked Questions)

1. What are the Types of Air Pollution?

There are 4 major harmful types of air pollution – carbon monoxide, sulfur dioxide, nitrogen oxides, and particulate matters and lead pollution

2. How Can the Use of Air Conditioners Cause Air Pollution?

The air conditioners release a gas called CFC (chlorofluorocarbon) which increases air pollution and adversely affects the ozone layer as well.

3. How Many People Can Die from Air Pollution?

According to the statistics provided by WHO, around 7 million people die every year just because of the various effects of air pollution.

4. What is the Air Quality Index?

The air quality index is measured by and used by the official pollution control authorities to show to the public how polluted the air currently is. It’s a measure that shows how polluted is the air that we breathe in.

5. What are the Measures for the Control of Air Pollution?

Various methods can be undertaken to control of air pollution – we can start ourselves by reducing the use of private cars, buying the electric appliances that have an energy star label, conserve energy whenever possible, and make less use of air conditioners.

6. How Can We Succeed in the Prevention of Air Pollution?

Prevention of air pollution will be a difficult task, but not an impossible one.  Apart from the individual efforts, the government authorities and the pollution control authorities should issue strict guidelines for it. Also, a good alternative should be provided for fuels and other industrial pollutants.
