Acidic precipitation

One of the most acute problems of the mankind today and in the near future is the problem of increasing acidity of the atmosphere precipitation and the soil cover. The areas of acidic soils never experience drought but their natural fertility is decreased and unstable. They become depleted fast and their harvests are low. Acid rains cause not only acidation of upper layers of water and soils. The acidity spreads to the whole soil profile with descending water flows causing considerable acidation of ground waters. Acid rains appear as a result of the human economic activity and are accompanied by emission of tremendous quantities of sulfur oxides, nitrogen oxides and carbon oxides. These oxides are transferred to far places, interact with water and turn into solution of the mixture of sulfurous acid, nitrous acid, nitric acid and carbonic acid that fall in the shape of "acid rains" on land, interacting with plants, soils and waters. The major sources of the whole process are burning of shales, oil, coils, gas in the industry, agriculture and in household use. As a result of human activity the concentration of oxides of sulfur, nitrogen, hydrogen sulfide and carbon monoxide has doubled. Naturally enough, this lead to the increase in the acidity of atmospheric precipitation, ground and underground waters. In order to solve the purpose the scale of representative measurements of the compounds polluting the environment must be increased.
