IMPRESSION OF ACID RAIN ON HUMAN SOCIETY: A REVIEW

Abstract

Acid deposition or acid rain is a wide expression that encompasses any kind of precipitation composed of acidic components such as, nitric acid, sulphuric acid. Precipitate becomes exceptionally acidic due to the presence of dissolved pollutants that are very much harmful to the environment. Non-acidic rain with pH between 5.0 and 5.5, but acidic rain might have pH approximately 4.0 as it contains dissolved nitric oxide and sulphur di oxide. Nitrogen oxides contribute to ozone at the ground level. Various industrial activities, automobiles can cause surplus nitrogen and sulphur which combine with rain to produce extremely acidic precipitation. These harmful substances interact with water vapours in the atmosphere to produce sulfuric and nitric acid, respectively. Although certain chemicals are released by decaying plants and volcanic eruptions, most of the acid rain is caused by anthropogenic activities. The largest sources are coal-fired power stations, manufacturing, and vehicles. Pollution that induces acid rain may additionally generate smaller particles. Entering of these fine particles to human lungs might be able to create and intensify existent medical issues. Breathing in acid rain might induce the development of pulmonary oedema, acid rain might cause erosion of teeth, irritation in eyes, cardiovascular disease, low birth weight etc. Hazardous medical impacts, specifically chronic and acute bronchial effects, can arise as early as the acid phenomenon's pre-deposition phase as a result of inhaling acidic particles and gas.
