In this paper we describe the regularities of the aerosol pollution distribution in the snow cover near Sovetskoye highway on the left-bank area of the Sovetskii district of Novosibirsk. The experimental data on chemical composition of the snow cover are analyzed using the mathematical models of aerosol emissions from the ground and elevated linear sources. Such basic toxicants as heavy metals and polycyclic aromatic hydrocarbons were used as chemical pollution parameters. Simultaneously, the ion composition of snow samples was determined.
