Wastes in the form of smoke from industry, power plants, automobiles and homes; and also due to burning of fossil fuels, spread pollution into our atmosphere. Aircrafts also release large amounts of burnt or unbumt fuel into the air. You may have seen a long trail of smoke left behind by a climbing jetliner.

i) Carbon monoxide
ii) Hydrocarbons
iii) Particulates
