Air pollution in Bishkek in different seasons of the year
The regime of atmospheric pollution in Bishkek, which is located on the sub-mountain plain of the northern part of the Tien Shan, in different seasons of the year is analyzed in article. The source material was continuous measurements of concentrations of 15 ingredients from December 2017 to May 2019. Characteristics of atmospheric pollution in seasonal, monthly and daily output were obtained. Dangerous, particularly dangerous and extremely dangerous pollution occurs during the cold period of the year, when the concentrations of small aerosol fractions (smoke, dust) can exceed 3, 5 and 10 times the maximum permissible average daily concentrations. They are associated with smoke emissions from Bishkek's heat electropower station and private-sector furnace heating. In the warm season, much less pollution is caused by ozone, nitrogen dioxide and, de minimis, nitrogen oxide. The problem of improving the quality of the Bishkek air basin requires the development and implementation of a special state program
