| Popis: | The chemical composition of solid and liquid phases of snow samples collected at different distances from various sources of anthropogenic emissions was studied. The main chemical elements polluting geosystems during the production of aluminum were determined and the halos of their spatial scattering were revealed. The total pollution index and the load of pollution were calculated. Based on quantitative indicators in comparison with maximum permissible concentration values, zones of ecological and geochemical risk were identified. A comparative analysis of the levels of the selected association of elements in technogenic aerosols of the area of the greatest risk and in background soil was carried out. |
