The selection of snow samples was performed in Mongolia (the slope of Mount Munku-Sardyk), Buryatia (ulus Ulbugay), Bratsk (Padun district) and in Irkutsk (Mount «Snow»). Element’s content in the samples of snow melt water was determined with the quadrupole ISP-MS mass spectrometer of Agilent 7500 ce. Determination of content of chemical elements (cations) in a filtrate of melted water of snow cover is carried out by a mass spectrometry method with the inductively coupled plasma (ISP-MS). The concentrations of about 70 elements have been defined. Also it has been determined that the side of Mount Munku-Sardyk (Mongolia) and ulus Ulbugay (Buratia) are the clearest ecological areas. The concentrations of some elements in the snow cover in Bratsk exceed the background concentration five times and more. The high coefficients of pair correlation between pairs of elements Al, Li, Be, Tl, V, F and the dependence of change of concentrations from the distance from the smelter has been established. It has been defined, that there is no exceeding in the residential area.
