Abstract

The Russian Federation regularly participates in the international program of the Acid Deposition Monitoring Network in East Asia (EANET). Two regions in the Asian Russia were selected for monitoring research: South-Eastern Siberia (three sites) and Far East (one site). A database on the chemical composition of atmospheric aerosol has been compiled over the operation period. The spatial and temporal variability of the ion composition of aerosol over five-year periods from 2001 to 2024 was studied using the ratio of the summed concentrations of the main ions. Based on data from other projects, some relevant trace elements in atmospheric aerosol were analyzed: Li, Al, Ti, V, Mn, Fe, Sr, Th, U, Ba, and Co (of terrigenous origin) and Cr, Cu, and Ni (of nonterrigenous origin). Their contribution to the total level of atmospheric air pollution at the EANET monitoring sites was assessed. The monitoring results on atmospheric depositions can be used for practical assessment of the environmental conditions, scientific research, and public information.
