Abstract
In 1999-2002, Karelsky Okatysh conducted environmental monitoring. The results of chemical sampling of soils, surface water and snow cover were used by the author for statistical analysis. Associations of chemical elements were identified using factor analysis. The average element contents in different soil horizons were compared. A map of S and Pb content in the soil organic layer was drawn up. The migration of chemical compounds in the Kento-Kenti aquatic system was studied. Data from snow gauge surveys for heavy metal content were processed using factor analysis. Factor score maps were constructed, which allowed the identification of areas with the highest deposition of (Cd, Mn, Zn); Fe; (Ni, Fe, Cu). The role of geochemical monitoring as a means of environmental control was shown.
