Abstract:
The chemical composition of dry deposition in the industrial center of Eastern Siberia, Irkutsk (Russia) in 2020 is analyzed. In the warm season, the content of PO43¯ in the dry deposition was increased, especially in calm weather. In autumn, the average concentration of NH4+ was three time higher as compared to August; Si2+, two time higher, and PO43¯, three time lower.
