Abstract
The Russian Federation participates in the international programme of 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 the Far East (one site). A database on the chemical composition of atmospheric aerosol was compiled. The spatial and temporal variability of the ionic composition of aerosol over five-year periods from 2001 to 2024 was studied using the ratio of the total concentration of the main ions. Based on data of other projects, some relevant trace elements in atmospheric aerosol were analysed: Li, Al, Ti, V, Mn, Fe, Sr, Th, U, Ba, Co (of terrigenous origin) and Cr, Cu, Ni (of non-terrigenous origin). Their contribution to the total level of atmospheric air pollution at the monitoring sites was assessed. The monitoring results of can be used for practical assessment of the environmental conditions, scientific research, and public information.
