Abstract

From September 2019 to February 2021, we analysed seasonal and interannual dynamics of the PAH concentrations in the atmospheric air of the city of Irkutsk and the southwest coast of Lake Baikal (the Listvyanka settlement). The comprehensive analysis of weather conditions (wind direction, relative humidity and temperature of the air as well as atmospheric pressure) was carried out. There were high correlations between meteorological parameters and PAH concentrations in the study area. Average PAH concentrations in the anomalously warm 2020 were three times lower than the average values obtained in the cold 2016. The proportion of the anthropogenic aerosol transport from the industrial sources in the Southern Baikal region towards Lake Baikal ranged from 61 to 71%.
