EFFECT OF METEOROLOGICAL CONDITIONS ON THE DISTRIBUTION OF PAHs IN THE ATMOSPHERE OF THE SOUTHERN BAIKAL REGION

摘要

The paper presents data on the content of PAHs in aerosols of the city of Irkutsk and on the coast of Lake Baikal (Listvyanka) between October 2015 and March 2017. We revealed seasonal and interannual dynamics in the distribution of PAHs in the atmospheric air of urban and rural areas. We carried out a comprehensive analysis of weather conditions, synoptic state, and data on an upper air sounding of the studied area using balloons. At two stations in the Southen Baikal region, we determined a high correlation between air temperature, atmospheric pressure, inversions, and PAHs concentrations.
