Ion and elemental composition of the atmospheric aerosol over West Siberia in 1997-2001

摘要

Some results of analysis of more than 400 aerosol samples made over West Siberia regions during last almost five-year studies onboard airborne laboratory are presented. Analysis of samples enabled us to reconstruct differential distributions of ions and elements. The chemical matrix for Si, Al, Fe, Mg, Ca, Ti, Cu, Mn, Cr, Ag, Pb, Ni, Ba, Sn, V, Mo, Co, B, K~+, Na~+, Cl~- SO_4~(2-), NO_3, Br~-, F~-, NH_4~+ and their vertical profiles were computed. Also analysis of differences in the chemical composition of near-ground aerosol is conducted based on the measurements at two points (Tomsk city and Kireevsk village) located at a 60-km distance from each other in summers 1997-1998. Significant differences caused by the impact of local sources and by the differences in the air masses are found for some chemical elements and ions.
