Air pollution is increasing day by day. Increase in the number of vehicles and automobiles on the streets and industries and factories in the cities are responsible for emergence of this problem.
Air pollution greatly effects the animals, plants and the environment as a whole. Science and technology in and around the world, has many positive impacts on our society and mankind, like eradication of diseases, growth of industries, improvement in agriculture, medicine, health care systems, transport and communication.
On other hand, these technologies have adversely affected the environment. With the gradual evolution in industrialization and urbanization, have rapidly depleted the natural resources such as forests, open lands and led to waste accumulation and different types of pollution such as air pollution, soil pollution, radiation pollution, water pollution, noise pollution, etc.
What causes Air Pollution?
The release of poisonous gases and particulate matter in the environment causes air pollution.
What are Air Pollutants?
The poisonous gases and particulate matter responsible for polluting the air are called air pollutants. For example: smoke, ozone, carbon dioxide (CO2), nitrogen dioxide (NO2), etc.
According to Air (Prevention and Control of Pollution) Act, 1981, India air pollutant is defined as “any solid, liquid or gaseous substance (including noise) present in the atmosphere in such concentration as may be or tend to be injurious to human beings or other living creatures or plants or property or environment (http://www.indiaenvironmentportal.org.in/files/file/NAAQStatus_Trend_Report_2012.pdf).”
Types of Air Pollutants
Air pollutants are classified into different types, depending upon the three parameters:
1. On the Basis of Origin
2. On the Basis of State of Matter
3. On the Basis of Their Chemical Composition
On the Basis of Chemical Composition
Based on the chemical composition of air pollutants, air pollutants can be of 2 types:
1. Organic Pollutants
2. Inorganic Pollutants
What are Organic Air Pollutants?
The air pollutants that are composed of organic matter are called organic air pollutants. For example, PAN and hydrocarbons.
What are Inorganic Pollutants?
The air pollutants that are made up of inorganic compounds are called inorganic pollutants. For example carbon dioxide, sulfur dioxide, nitrogen dioxide, etc.
Thus, air pollutants are of different types and nature but have similar function i.e. they affect the environment adversely. Either in their primary form or combined form, they affect nature on the whole.
