Environmental pollution is the unfavorable alteration of our surroundings wholly or largely as a by-product of man's action through direct or indirect effects of changes in energy patterns, radiation levels, chemical and physical constitutions of environment and abundance of organisms. Substances that cause pollution to the environment are called pollutants. They are the residues of things that man makes, uses and throws away. These residues pollute soil, water and air. The atmosphere in highly populated area is very rich in dust, smoke and SPM all due to vehicular exhausts and industrial emission.
