Abstract
The chemical composition of solid and liquid phases of snow samples taken at different distances from emission sources was studied, priority elements polluting geosystems during the production of aluminium were determined and the halos of their spatial scattering were revealed. Total pollution index and the load of pollution were calculated. On the basis of quantitative indicators, in application to the MPC, the zones of ecological and geochemical risk were revealed. A comparative analysis of the levels of selected elements in the association of industry-induced aerosol in the area of the greatest risk and in background soil was carried out.
