The distribution of trace elements in surface continental waters and the character of their migration in water

The results of studying the elemental composition of surface continental waters in the European Russia from tundra to and zone are discussed. The relative concentrations of elements in the solid residue of waters from various natural-climatic zones are evaluated, and the enrichment or dispersion of continental waters by these elements are analyzed as compared with their clarkes in the rocks that occur in the catchment areas. The coefficients of migration in water are evaluated, and the major elements with respect to which surface waters enrich under anthropogenic load are identified. The territorial distribution of higher concentrations of the most hazardous elements in waters of lakes is characterized.
