What is Air Pollution?

With the advancement in science, technology and change in the lifestyle of man, despite immense benefits what is the most noticeable side effect?

According to me, it is POLLUTION. Pollution whether air pollution, water pollution, soil pollution, radioactive pollution or noise pollution. Pollution is the most common side effect that technology has given us.

In this blog post, my concern is AIR POLLUTION. Now, you may think, why air pollution? This is because each and every one of us is facing it and it has adversely affected both plants and animals. 

Newspapers are filled with news on air pollution and how it is affecting people every day. Air pollution is not a problem of an individual city, place or country. It  is now a global concern. 

Thousands of vehicles running on the roads, chimneys blowing out every day, emission from agricultural burning, forest fires, volcanic eruptions and tree felling on the cost of development and industrialization have adversely affected the mother Nature. More and more numbers of vehicles are added every day on the streets that vomit poisonous gases in the environment.

What is Air Pollution?

Different agencies define air pollution differently. I have put down few definitions of air pollution from different national and international organizations.

WHO (World Health Organization) defines air pollution as “Air pollution is the contamination of the indoor or outdoor environment by any chemical, physical or biological agent that modifies the natural characteristics of the atmosphere.”

According to United Nations Economic Commission for Europe, Air pollution means the introduction by man directly or indirectly, of substances into the ambient air resulting in deleterious effects of such a nature as to endanger human health, harm living resources, ecosystems, material property and impair or interfere with amenities and other legitimate uses of the environment.

In India, The Air (Prevention and Control of Pollution) Act, 1981 defines “Air pollution is the presence of  any solid, liquid, or gaseous substances 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”.

According to the Central Pollution Control Board (CPCB), India “Air pollution is the introduction of particulates, biological molecules, or other harmful materials into Earth’s atmosphere, causing diseases, death to humans, damage to other living organisms such as animals and food crops, or the natural or built environment.”
