Abstract: The formation of the chemical composition of the snow cover background territories of taiga of the European North-East of Russia (Komi Republic) takes place mainly at the expense of soluble compounds of elements. The coefficients of enrichment (Ke.) elements of the soluble fraction of snow are significantly greater than for the fraction of low-soluble compounds and close to the values of coefficients of accumulation for atmospheric aerosol. Geochemical the ranks of metals for snow cover and soil are differ. These facts shows that the chemical composition of the snow cover background territories of taiga zone is formed mainly through long-distance migrations, the influence of local natural and man-made sources is less important. According to calculations Ke. for items in the snow two groups were allocated to metals terrigenous origin and mixed terrigenous and anthropogenic origin. Rows calculated based on the values Ke. for snow, indicate the specific character of formation of the atmospheric aerosol in the studied area in comparison with the European territory of Russia. There is the influence of anthropogenic emissions and regional geochemical features of the territory. The equity ratio of elements in snow cover on the taiga are estimated. The share of low-soluble forms of metals in the composition of the snow cover decreases with latitude.
