Pollution Predict

Effects of air pollution on human beings ....... Extract from the Air Prevention and control act- 1981

Hydrocarbons emitted by automobiles are toxic and react with hemoglobin in the blood. The effect of nitrogen is adverse and permanent. It increases children's susceptibility to diseases like influenza. Sulphur dioxide in the air spreads air acidity and corrodes buildings. It causes irritation to various parts of the respiratory systems.

The heart may be damaged by air pollution, secondary to lung diseases. Nitrogen dioxide results in pulmonary edema and aggravation of coronary disease. Toxic effects of lead pollution include impaired IQ development defects in children. These are few of the many effects of air pollution on human beings.
