This article examines the concentrations of heavy metals in soil and water samples taken in cities and districts of Central Kazakhstan and examines the results of studying the territorial features of the impact of technogenesis on the environment. The ecological condition of the territory of Central Kazakhstan is largely due to anthropogenic factors, which often exceed the ecological capabilities of the environment, disrupt its normal functioning, which has a negative impact on human existence. In the course of the work, a study of the elemental composition of the soil was carried out, assessment and monitoring of the quality of surface waters in the territory of the Karaganda region were carried out according to the Unified System of Classification of water in water bodies, statistical processing of the obtained results was conducted using parametric methods of analysis. The study period was 10 years, from 2011 to 2021. As a result of the study, mercury pollution in the Nura River was noted, with the average mercury content in the amount of 15.137 mg/dm³ exceeding the MPC by 30.2 thousand times. The cities of Karazhal, Priozersk, Saran, Satpayev, Shakhtinsk, Topar township and all rural territories are classified as favorable zones, the cities of Balkhash, Zhezkazgan, Karaganda, Temirtau are considered unfavorable risk zones. Industrial enterprises of the mining and metallurgical industry of Kazakhmys Corporation LLP, Arcelor Mittal JSC, Balkhash Mining and Metallurgical Combine pose a threat to environmental objects, therefore, effective policies are required to mitigate the effects of environmental pollution. Measures to prevent the negative impact of technogenic factors on the health of the population, as a limiting link for the further development of the economy, are important for the Republic of Kazakhstan.
