Acid Rain

Causes of Acid Deposition

acid deposition
Some industries or power plants that use low-quality fuels, the atmospheric air releasing large amounts of sulfur and nitrogen oxides. These contaminants can be transported over distances of hundreds of kilometers by air currents, especially when emitted into the atmosphere from very high chimneys that reduce pollution in the vicinity but the move to other places.

In the atmosphere of nitrogen and sulfur oxides are converted into nitric and sulfuric acid back to earth with rain or snow precipitation (acid rain). Other times, though it does not rain, are falling solid particles with acid molecules attached (dry deposition).

Normal rain is slightly acidic and lead forms carbonic acid when carbon dioxide from the air dissolves in the water that falls. Its pH is usually between 5 and 6. But in areas with polluted air by acidifying substances, the rain has pH values ??of 4 or 3, and in some areas where fog is acidic, the pH can be 2.3, ie similar the lemon juice or vinegar.

What is Acid Rain?

Aquatic and terrestrial animals, trees and plants and even human infrastructure suffer the damaging effects of acid rain. It is the fault of man, which emits nitrogen oxide and sulfur dioxide from their factories, power plants, cars, etc.
The effects of acid rain can be devastating, since the acidification of rivers, lakes and seas hamper aquatic life, to wear and death of plant life in forests.

To make matters worse, when acid rain falls, dragging the acidified water with natural soil fertilizer, which gives a total impoverishment, which ends stressing the plants, since they removed the minerals and essential ions , thus producing more carnage.
But not only affects living things, but it corrodes buildings and human infrastructure. For example statues and monuments made of marble or limestone, fall apart with each acid rain. Read the rest of this entry »
