Аннотация (краткое описание)
Near the ore deposits as well as in adjacent territories near enterprises and areas for storing raw materials and waste during the enrichment and processing of heavy metals, there are zones of accumulation of high concentrations of substances involved in the technological process of metallurgical production. To control the negative impact to the environment, to reduce negative consequences, it is required to monitor and carry out environmental protection measures aimed at preserving the acceptable properties of the habitat of various types of organisms in the soil, water and air. The harmful impact of human economic activity to the nature can be remote both in time and in space. This is due to a number of factors: the persistence of the processes of impact to the nature caused by the dynamics of biogeocenoses, the resistance and adaptation of the ecosystem to negative impacts, the effects of summation and migration of pollutants, etc. Studies of heavy metal contamination of snow cover and soil were carried out by taking soil and snow samples for atomic sorption spectrometry. When assessing the distribution of pollutant concentrations,the maps of contamination of Ile River delta territory by Copper (Cu), Zinc (Zn), Lead (Pb), Nickel (Ni), Cobalt (Co), Cadmium (Cd) were created. This made it possible to clarify the mechanism of transport of pollutants and identify areas of accumulation of heavy metals in snow and soil. Based on the results of the analysis, were made the conclusions about participation of heavy metal deposits in the emissions of substances accumulated in the lithosphere. This is confirmed by the relative location of emission sources and pollutant accumulation zones. Transfer over land occurs over longer distances compared to air trajectories crossing the waters of the Lake Balkash. Research results can be taken into account for the development of environmental protection measures. © 2023, National Academy of Sciences of the Republic of Kazakhstan. All rights reserved.DOI
