Abstract

Chemical composition of atmospheric aerosol, atmospheric precipitation, and dry deposition in the industrial center of the Eastern Siberia, town of Irkutsk, in 2019-2020 was analyzed. 2019 is characterized by the record-breaking forest fires in the Siberian Region for the last 10 years. Sulfur and nitrogen streams flowing with atmospheric depositions to the underlying surface in Irkutsk were calculated. Sulfur and nitrogen inputs with atmospheric precipitation were higher than with dry depositions. It is noted that the flows of these substances were more intensive in 2019, especially during the warm season of the year. This study was supported by the State Project 0279-2021-0014.
