Abstract
The article provides information on literature and patent information on the analysis of heavy metals formed during the extraction and processing of various types of raw materials for the production of non-ferrous metals and chemical products. The influence of heavy metals on the environment and living organisms, fauna and flora, as well as people living in different industrial regions of Kazakhstan is shown. Migration of heavy metals in the soil cover hydrosphere and atmosphere is shown. Based on the analytical review, the goals and objectives of the study are outlined, the chemical composition of raw materials for the main heavy metals formed in solid and dust - like production waste, and for technological processing in the production of lead and zinc in the East Kazakhstan and Turkestan regions is shown. Information is provided on the presence of heavy metals in the soil and their purification by various bioremediation methods. The data of soil analysis on the territory of the Turkestan region in recreation areas of people and in non-ferrous metallurgy enterprises nearby to the mining complex are presented. The dependence of the distribution of heavy metals and the chemical composition of the analyzed samples taken in various points of the Turkestan region and the city of Shymkent is shown. Data on the maximum content of heavy metals in the soil at which experimental worms die are established.
