The problem of change in geochemical composition of the Western Siberia environment over the last decades is discussed based on results of studying stratified formations of the glacier BolshoyAktru (Mountainous Altai). It is established in the last 50 years changes have taken place in chemical composition of the glacier atmosphere. Steady input of a significant amount of microelements is observed. It is especially characteristic forV, Be, Та, GrandSb. Stages of the maximum and the minimum input of elements are allocated. Judging by the spectrum of chemical components, the main source of their input are industrial enterprises of the East Kazakhstan area, Republic Kazakhstan (Ust Kamenogorsk, etc.).
