Abstract
Variability of concentration of chemical elements in snow cover of the typical regions of the central part of the Western Siberia is studied. Decrease of variability and concentration of chemical elements has been found in the south-north direction. This tendency is observed not only for “soil-erosion” elements (Сa, Fe, Al, Sr), but also for those considered “technogeneous” — V, Cо, Pb, Zn, Cd. Northward decrease of concentrations is the most pronounced between the steppe and southern taiga zones.
