| Summary: | The aim of the study is to reveal the features of the accumulation of metals and metalloids (MM) in the PM10 fraction of road dust at different traffic levels in the eastern part of Moscow. Highlighted by elutriation PM10 particles were studied in the municipal areas of Sokolinaya Gora, Perovo, Ivanovo, Novogireevo, Veshnyaki, Novokosino and Kosino-Ukhtomsky of Eastern Administrative District of Moscow. The concentrations of MM in PM10 were determined by mass-spectral and atomic-emission methods. The geochemical specialization of PM10 fraction relative to the upper continental crust has the form Cd22Ag21Sb21Sn11Se10Cu9Bi9Pb8Zn8Mo7W4Te3S2P2, which indicates the technogenic sources of these MM. For the rest MM natural-technogenic and natural sources predominate. The enrichment of the PM10 with Zn increases with the growth of the transport load, the maximum contents of Cu, Mo, Cr, Fe, V, Mn, Ba, Al, Ti and K are typical for large roads, and Sr, Nb, Ga, S, W, Pb and Te for medium roads. The total enrichment of PM10 with MM is maximized on medium and large roads, where a very dangerous ecological situation is formed, on the Moscow Ring Road and small roads it decreases to a dangerous. |
