Problems of environmental pollution with heavy metals in the Russian Federation

Abstract

The causes and sources of pollution of the natural environment with heavy metals are analyzed in the study. Basic information on indicators of environmental pollution with toxic metals was presented. When assessing the state of the natural environment, the author emphasizes the need to take into account that the intake of heavy metals is caused by both natural sources and anthropogenic impact. The study provides a review of scientific sources devoted to analytical methods for determining the content of heavy metals in biological media. Within the framework of the study, the author substantiated the conclusion that it is necessary to modernize methods for determining the content of heavy metals in biological media, given that it is possible to assess the level of the content and the adverse effects of heavy metals on the human body only with accurate quantitative indicators of the background content of elements in biological media. In addition, characteristics of the microelement composition of the environment for the region under study are subject to mandatory registration. The author emphasizes the need to develop methodological approaches and establish the background regional levels of metal content in biological media.
