Abstract

The results of the study of the spatial-temporal variability of the counting concentration of the highly dispersed (VDA) and submicron fraction (SMA) of aerosol, small gas impurities (sulfur dioxide SO₂, nitrogen dioxide NO₂, ozone O₃) over water area of Lake Baikal during the expedition on board the research vessel "Academician V. A. Koptyug" from July 29 to August 11, 2020 are presented. The average daily concentration of ozone over the lake was 67 μg/m³, sulfur dioxide - 7 μg/m³. The highest concentrations of small gas impurities and aerosol particles were observed in areas with a high anthropogenic load and in areas under the influence of forest fires. The average values of the counting aerosol concentration of VDA fraction and SMA in the lake area during were 3055 particles/cm³ and 98 particles/cm³, respectively.
