Химический состав дорожной пыли и ее фракции PM10 как индикатор загрязнения городской среды

Study outcomes of 32 heavy metals and metalloids concentrations in road dust and its PM 10 fraction on Moscow roads with different traffic intensity have been presented. Priority pollutants of road dust and its PM 10 fraction in Moscow include Sb, Zn, W, Cd, Sn, Cu, Bi, Pb, Mo; PM 10 pollution is up to 6 times more intense than total dust. РМ 10 particles mostly accumulate Sb, Zn, W, and Cd in all administrative districts, but as for the Western and South-Western administrative districts those in addition are Sn and Bi, Sn and Cd for the Central district, Cd and Bi for the Southern district. PM 10 particles are especially dangerous in the courtyards of residential buildings where pollution reaches extremely high levels.
