Аннотация (краткое описание)
The natural environment of large cities is subject to strong anthropogenic pressure. Both the soil and the hydrosphere are exposed to pollution. At the same time, the atmosphere is one of the mechanisms means for the transfer pollutants that enter living organisms. The study of distribution routes, chemical reactions and interaction with the biosphere of released into nature substances and their compounds help to find means to minimize the negative impact to the environment. One of the ways to reduce costs is to find the best options for solving environmental problems. Such solutions are not possible without monitoring of pollutant emissions and environmental analytical control in particular. For the city of Almaty and the adjacent territory, for the first time in 2018-20, a research program on heavy metal pollution was carried out. This project made it possible to study the changes dynamics in soil and snow cover concentrations of the following elements: Copper (Cu), Zinc (Zn), Nickel (Ni), Lead (Pb), Cobalt (Co), and Cadmium (Cd). Along with the lithosphere, the water area of Kapshagay reservoir was studied. In addition, there was obtained the data on oxidizability, acidity, salinity and suspended solids. The dynamics of pollution by polychloryl biphenyl compounds has also been studied. The metals concentration was determined by the flame atomic absorption spectrometric method. The presence of these chemical elements in the lithosphere allowed assuming the presence natural sources of pollution against the background of anthropogenic factor exclusion. The lead content occupies a special position, since the presence of anthropogenic source is not excluded and requires further research and evaluation of the components of the incoming part of this chemical element balance. The article provides an analysis of the search for a source of copper pollution of the snow cover in Almaty agglomeration territory. The source of copper emissions is assumed to be of natural origin. Based on the analysis of the wind regime, the location zones of sources of lithosphere pollution by copper are potentially determined. The study of the location of areas free from snow cover during the period of increasing copper concentration will allow determining more accurate location of zones producing the copper particles transfer. © 2023, National Academy of Sciences of the Republic of Kazakhstan.
