CHEMICAL ELEMENTS AND SUBSTANCES – INDICATORS OF ENVIRONMENTAL POLLUTION IN THE ALTAI REPUBLIC
Abstract
Relevance of the work is determined by the need to identify and use for scientific and practical purposes priority indicators of regional and local pollution of chemical elements and substances of natural environment components on the territory of the Altai Republic. The main aim of the research is to establish associations of chemical pollutants of the natural environment, to study the features of their behavior in natural environments and stratified natural formations, to identify priority indicators of areas and zones of imposed chemical pollution in the region. Methods: collection, generalization and comprehensive analysis of data contained in published and stock materials of scientific and industrial organizations for the assessment of the ecological and geochemical situation on the territory of the Altai Republic and adjacent regions, processing of systematized data by methods of applied statistics. Results. Regional and local factors of negative impact on the natural environment of the Altai Republic were described. The environmental consequences of current and past environmental pollution were given. The high information content of stratified natural formations in the study of past pollution was set. The main associations of ecotoxicants of chemical nature typical for the region were identified. The features of pollution of natural environment components during cross-border transfers of pollutants and when exposed to local sources were revealed. Natural environments that are representative for the study of superimposed pollution, as well as chemical elements and substances that are indicators of anthropogenic pollution were identified. Concentrations of priority indicators in areas of snow and soil contamination exceeding environmental and hygiene standards were established. The author made the conclusion on the greatest danger to the natural environment of the region of xenobiotics represented by technogenic radionuclides, components of rocket fuels, and organochlorine pesticides.
