Earth is surrounded by thick envelope of gases called atmosphere. Atmosphere is divided into different layers depending upon the distance from the sea level. The nearest rexampleion which extends to the height of about 10 km from sea level is called troposphere. It contains about 80% of total mass of air & almost all the water vapours.

The rexampleion above the troposphere between 50 km is called stratosphere. Atomspheric pollution is generally studied under two heads.

(a) Tropospheric pollution

(b) Stratospheric pollution
