Atmosphere Pollution Observations of an air basin state of a territory of Kyrgyzstan showed that the sources of atmosphere pollution may have a global, regional and local character. The main sources of air pollution are a motor transport, enterprises of power engineering, building materials, municipal services, mining and process industry, individual sector. The cities Bishkek, Osh, Tokmok, Kara-Balta have the greatest level pollution by some polluting substances in comparison with cities of the former Soviet Union of the same scale. A decrease of wastes in atmosphere is connected to recession of manufacture in the republic.
Hydrocarbons are on the basic place among specific substances.
The analysis of change of average concentration of the basic polluting substances in atmospheric air for 1992-97 in Bishkek has shown the tendency to reduction of sulphur dioxide in atmosphere. The concentration of other polluting substances grows. Thus, despite a decrease of total quantity of polluting substances for period of 1989-95, an atmosphere pollution still represents an ecological danger. Observations on a presence of heavy metals in atmospheric air, spent in 1990 and 1996 in a number of cities of the republic, have shown that their concentration on the order, and sometimes on two orders, is lower than extreme allowable concentration Recently, one of the widespread phenomena which results in essential ecological changes on territories of various scale is a falling loss of acid rains. Study of spatial laws and temporary tendencies of acid falling and chemical composition of atmospheric precipitation for a number of cities of Kyrgyzstan during period 1991-94 has shown that a meaning of pH varies from 6.03 up to 7.67.
