| Popis: | The relevance of the work is caused by the need to generalize extensive diverse information on the ecogeochemistry of mercury in natural environments and man-made objects of the Altai Republic. The aim of the research is to collect and systematize data on the levels of mercury content in the components of the natural environment in the background and contaminated areas of the region. Methods: study and analysis of published and stock materials of ecological and geochemical works on mercury carried out in 1980–2020 by scientific and industrial organizations in the territory of the Altai Republic. Results. Data on the main natural and anthropogenic sources of mercury emissions in the region and the levels of mercury pollution of the natural environment in the zones of their impact are presented. For the first time, the levels of mercury content were estimated for a large complex of components of the natural environment. The predominance of background concentrations of mercury in them and their close relations with the rocks of the folded basement are shown. Altitudinal zoning in mercury distribution in the soils of natural landscapes is planned. The background of mercury in rocks and other components of the natural environment of the region were preliminarily estimated. Its level is slightly increased relative to the world's Clarks. Conclusions. The geological formations of the region are not mercury-specific. The increased level of local superimposed mercury pollution of natural environments is mainly due to its past extraction and use. Mercury concentrations in polluted natural environments are closely related. The main sources of anthropogenic mercury emissions are stale waste from mining enterprises. Modern economic activity in the region does not create dangerous pollution of the natural environment. |
