摘要

The chemical composition of aerosol and precipitations on the southwest coast of Baikal during intensive forest fires in Krasnoyarsky Kray and Yakutia in July 2018 was analyzed. An increase in the concentrations of ions and PAHs in the fine fractions of aerosol particles (<1.3 μm) sampled in Listvyanka was observed. The concentrations of Na~+, K~+, Ca~(2+), SO_4~(2+) and PAHs in the composition of the aerosol in Bolshie Koty within the period were increased. According to the analysis of the synoptic situations and chemical composition of atmospheric depositions, the aerosol sampled in 15-18 June 2018 was a product of forest fires.
