“…For this purpose, it is necessary to take into account the value of the natural geochemical background, which, in ore areas is generally higher than the MAC value, due to the presence of ore elements. [3]. Normalizing the indicators obtained through testing (chemical elements concentrations) to the local geochemical background just allows one to take into account fluctuations in concentrations of pollutants, which are introduced by the mining complex itself.…”

The paper presents the authors’ research findings that enable to avoid unreasonable charges for negative environmental impact by applying mathematical statistics and GIS technology, modern methods of geochemical sample data processing, as well as by analysis of the dynamics of engineering-geological phenomena in the mining complexes areas. The authors’ data on the manifestation of high concentrations of toxic elements in some landscape components on the territory of mining complexes are provided. The latter, according to the authors, are associated with the outcrop of molybdenum ore occurrences, which were previously blocked by thin Pleistocene deposits. Then, due to sloughing of these deposits, molybdenum compounds began penetrating to the environment components.
