• Street dust (SD) acts as a sink and a source of atmospheric particulate matter, which is especially significant in urban environments. World studies of natural and anthropogenic impacts on the elemental composition of SD are generally limited to specific areas or case studies. The objectives of this study are to determine the impacts of different anthropogenic atmospheric dust emitters and natural factors on the chemical composition of SD, and to define sources of variance in elemental composition of SD, temporal variations and geochemical associations of elements on large number of samples, collected in different time periods, anthropogenic environments and geological settings. Nested ANOVA shows that the majority of the elemental-level variations were found to be regional ones. Increased variations on local scale were observed for Hg, Mo, Ni, Zn and Ag. Increased temporal variations were observed for Zn, As, Cd and Pb. Spatial variations within the same sampling location were increased for Hg and Ag. Three anthropogenic geochemical associations were detected: Coal mining and coal-fired power production enriched SD with Al, Co, Fe, La, Sc, Th, Ti, V, Zr and U, metallurgy with Cr, V, Ni and Mn, and urbanization with Ag, Bi, Ca, Cd, Mg, Mo, Pb and Zn.
