Write a short note on Air pollution. |
|
Answer» The contamination of air with chemicals, smoke, dust particles and disease-causing agents is called air pollution. When fossil fuels are burnt they produce different oxides of nitrogen and sulphur that dissolve in rain to give rise to acid rain. The combustion of fossil fuels also increases the amount of hydrocarbons. Presence of high level of pollutants causes visibility to be lowered. Regularly breathing air that contains any of these substances increases the incidence of allergies, cancer and heart diseases. |
