THE FEATURES OF THE FORMATION OF THE CHEMICAL COMPOSITION OF SMALL LAKES IN THE KOLA PENINSULA IN TERMS OF ENVIRONMENTAL CONTAMINATION AND ACID LOAD

Geochemical watershed transformation occurring as a result of the joint impact of natural and anthropogenic factors causing changes the concentration of chemical elements entering in the water bodies. One of the main manifestations of environmental contamination is acidification of waters of small lakes. The small lakes of the Kola Peninsula, having predominantly atmospheric source, serve as an indicator of acidification processes or restoring water and, with a certain chemical composition and low salinity, the most vulnerable.

Keywords: lakes, emission of sulphur and metals, acidification of water, sensitive rocks.
