Please read on layers and composition of the atmosphere here.

Air pollutants include smoke generated from the burning of petroleum products, coal, wood, rubber and plastics. Other forms of air pollutants are smoke from chimneys, industries and vehicles.

Carbon(II)oxide (CO) is a gaseous pollutant that could lead to suffocation and death in animals when Inhaled.

Sulphur(IV)oxide (2) and Nitrogen(IV)oxide (NO2) are also considered as air pollutants. These gases will contribute to the formation of acid rain which will in turn destroy the leaves of plant.
