This paper provides the study of snow cover in Irkutsk Oblast industrial centers (Eastern Siberia), such as Angarsk, Irkutsk, and Shelekhov. Elemental composition is represented as an environment pollution indicator. A group of elements was determined for each city characterizing main anthropogenic emission sources. High level of snow cover pollution was found in Angarsk. Chemical composition of snow cover in Shelekhov is indicative of high aluminum concentrations. Metal accumulations were calculated in snow cover in these industrial cities and compared with the data on the background area (Baikal-Lena Nature Reserve). Ratio of soluble and insoluble forms of elements in snow cover was studied.
