Abstract

The results of evaluations with radioactive indicators show that about 90 % of air pollutants from local and regional sources are washed away by precipitation; self-cleaning effect of the atmosphere is shown through spatial and temporal changes in chemical composition and acidity of atmospheric precipitation. It is necessary to carry out systematic research on a single, strictly established procedure, which was first organized in the Hydrometeorological Service of USSR, in order to find out the spatial inhomogeneities and geographical patterns in the change of precipitation composition. The purpose was to obtain the data in natural conditions that makes it easier to determine the anthropogenic and especially technogenic impact. The great amount of data accumulated over 50 years, which allows to make certain generalizations. The article provides guidance on the use of precipitation chemical composition in the environment-oriented practice.

Keywords

precipitation, chemical composition, acidity, environment, rainfall, nature conservation.
