Abstract
The seasonal variability of aerosol composition was studied according to three-year field observations in Moscow and one of its suburbs from the autumn 2019 by the autumn 2022. A high correlation has been established between the aerosol concentration of PM2.5 and PM10 fractions both in Moscow and in the suburb, as well as between these points for each fraction. Taking into account the seasons, meteorological conditions and sources, the level of aerosol pollution of near-surface atmospheric layer, typical for Moscow metropolis and the suburb, has been determined. Two identical groups of chemical elements were identified in the near-surface aerosol for the city and the suburb at any time of the year – terrigenous (Th, Al, U, La, Li, Sr, Ba, Mg, Fe, Cs, Co, Mn, Cr, K, Ca) and non-terrigenous (Mo, Cu, Zn, Pb, Sn, S, Sb, Cd, Se, Bi).
