Acid Rain

The world we live in today has become a nest for pollution, toxic waste and environmental deterioration. In order to improve our planet, acid rain is a main factor to be considered and must be controlled before the damage worsens.

In order to understand what acid rain is, we must first understand the term “acidity”. Acidic is a way to describe chemical compounds and it is measured on the pH scale, a logarithmic measure of the concentration of hydrogen ions (H+) in precipitation (1). This scale is numbered 0 to 14, where substances with values below 7 are considered acidic and the ones above 7 are basic. Pure rain has a pH between 5.6 and 5.7; therefore, any acid precipitation with a pH below 5.6 presents concerns (3).

Rain itself tends to contain acidity, caused by the rain’s reaction to the carbon dioxide in the atmosphere and by the natural phenomena such as volcano eruptions and fires, nonetheless, the degree of acidity in the rain caused by nature, is digested by the rainfall and is not sufficient to cause damages to our environment. Therefore, acid rain is rain that has been made acidic not by nature, but by man-kind oxide pollutants such as sulfuric dioxides (SO2) and nitrogen oxides (NOx), which are the results of power plants that perform fossil fuel combustion and are also the result of exhaust from the motor vehicles. These particles react with the moisture in the air to produce precipitation of new chemical properties such as sulfuric acid and nitric acid, which are two major components of acid rain (3).

These acidic particles are dropped through acid deposition that falls from the atmosphere in the form of either wet or dry. Wet deposition is visible precipitation that can take the form of acid snow, sleet, h...

...ordingly; they may have a more direct harmful approach to some elements such as terrestrial soils than on automotive coatings. Finally, the paper focused on the issue that the reduction of acid rain may be resolved if one carries out various actions. We must remain comprehensive to the fact that acid rain is not a clearly advertised harmful aspect in life that we know of. The damage of acidity portrays itself as a vicious never-ending circle that must be stopped at one end or another.

“We have already seen acidified lakes no longer able to support fish populations and other aquatic life. We have seen the faces of buildings and the faces of statues lose their integrity. […] Without a firm commitment both to developing improved pollution control methods and to applying those methods rigorously, the problems of the past could be a prelude to an acid rain future”(3)
