Acid rain is caused by two major air pollutants named sulphur dioxide and nitrogen dioxide.
- Acid rain contaminates water and enters man’s body which may cause potential threat to human health.
- Many bacteria, aquatic organisms and blue-green algae are killed due to acidification which disturbs the whole ecological balance.
- Acidification of soil leads to reduced forest productivity.
- Acid rain causes extensive damage to buildings (e.g. - Taj Mahal) and material of marble, limestone, slate etc.
