Samples of road dust and roadside soil were taken on roads of various traffic intensity in the South-Eastern district of Moscow. Principal physical and chemical properties and the geochemical specialization were determined. The road dust has a higher pH (average 7.3–7.6) and conductivity (average 186–387 μS/cm), but lower content of organic carbon (average 2.1–4.0 %) than soil. Sb, W, Zn, Pb, Mo intensively accumulate both in soil and dust. The sources of heavy metals are emissions of vehicles and destruction of road infrastructure.
