Chlorofluorocarbons (CFCs) : Chlorofluorocarbons are the compounds containing carbon, chlorine and fluorine. These compounds are used as an insulating material in air conditioners and refrigerators. Chlorofluorocarbons are also used in shaving foam and cleaning agent. These chemical compounds (CFCs) react with the ozone gas and leads to the depletion of the ozone layer and formation of holes in it.
Lead : When petrol is burnt in automobiles it releases lead as a pollutant which is absorbed by our body. It is poisonous and can damage our brain, liver and kidneys.
