Effects of Air Pollution














            Acid Rain

            Sulphur dioxide is produced in factories

            where coal is burnt to produce energy. It is a

            poisonous gas which irritates the eyes and

            lungs. It mixes with water vapors in the air

            and forms sulphuric acid. This acid dissolves

            in the rain water resulting in acid rain, which

            can harm plants, animals and buildings.
