The word ‘ acid rain ‘ refers to the precipitation of wet or dry acid compounds from the surface of the earth’s atmosphere.
Sulfuric acid and nitric acid are known as the key agents responsible for acid rain.
Industry-emitted smokes are the main source of sulphur dioxide, while motor vehicle-emitted smokes are the major source of nitrogen oxide.
Such pollutants were combined with ambient moisture to form the sulphuric acid and nitric acids that sooner or later precipitate in various forms on earth.
Acidity is determined by the relative concentration of hydrogen ions on a pH-scale.
The scale ranges from 0 to 14 where the lower end reflects minimal acidity and the high alkalinity at the higher end.
The acid rain is related to various types of precipitation.
The long-term effects of acid precipitation on human health and agricultural production have still not been precisely ascertained.
A stream or lake’s Eco-system can be seriously impaired if its pH falls below 5.
Within these environments, total biomass is reduced from two to ten times, because few species can absorb acid.
Species diversity is also rising.
Acidification has the most serious effect on ocean animals (fishes).
Acidic factors impair the fish’s reproductive ability, which results in a steady decrease in the fish population.
Buildings and monuments are being demolished because the acid deposition increased the potential for erosion.
