Abstract
According to the V.I. Vernadsky law, chemical elements are distributed unevenly in natural objects. Knowledge of the content of chemical elements in a particular area helps in solving various environmental problems. As a result of economic activity, there occurs anthropogenic transformation of the natural environment, including changes in the geochemical properties of landscapes. For an objective assessment of the anthropogenic impact when studying various territories, it is necessary to take into account the background content of macro- and microelements. Since there is a constant anthropogenic impact on the natural environment, the data on background content must be updated. The article presents the results of the content study conducted for some macro- and microelements (Sr, Pb, As, Zn, Ni, Co, Fe2O3, MnO, Cr, V, TiO2) in landscapes in the Perm region. To determine the content of these elements, the method of X-ray fluorescence analysis was applied. As a result, the geochemical specialization of the region and its natural areas (Northern Urals, Western Urals, Middle Taiga, South Taiga, Mixed Coniferous-broad-leaved Forests and Kungur forest-steppe) was determined, geochemical series were constructed, accumulating and dispersing elements were identified. The local background content of the studied elements was determined for each natural area and also the Perm region as a whole. The data obtained can be used to assess the anthropogenic impact on the natural environment.
