The growth of production zones in the city of Aksai in the West Kazakhstan region leads to contamination of the soil cover, which, in turn, causes a chain reaction of pollution. Due to soil contamination, soil moisture and the underground surface are polluted. As a result, the processes in the soil change, the vital activity of plants, animals and microorganisms are disrupted. The article presents data on the study of changes in soil cover under the influence of human activity. The results of the conducted studies on the determination of the humus content and pH level, the content of heavy metals in technogenically disturbed soils in the adjacent territory of the natural gas processing enterprise are presented. The obtained data on the gross content and mobile forms of heavy metals indicates that the maximum permissible concentration level for these pollutants is not exceeded.

City Park

Based on a comprehensive assessment of the state of the park landscape, the level of its anthropogenic transformation is determined, which is necessary to identify the potential for restoring the natural biodiversity of the object. It is reported that the plantations and soil cover of the park of the 50th anniversary of VLKSM are very heterogeneous; they reflect the history of park establishment. The soil cover consists of three main types: sod, bog and urbanozem. It should be stressed that the best preserved part of the park is the plot with boggy soils around the pond. Herbaceous plants growing on the plot are very similar to the species composition of the ground cover of overgrown peat bogs. Over the 40 years since the foundation of the park, a high level of pollutants has been accumulated in the soil, which allows us to state that the negative impact occurs constantly. Consequently, the existing plantings are insufficient to protect visitors from vehicle emissions from the roads along Yasnaya and Shaumyana streets. There are enough natural elements in the park of the 50th anniversary of VLKSM; this should be taken into account in its redevelopment. There is an opportunity to restore the reservoir and return the plantings to their natural appearance. It is proposed to add elements of landscape decoration in the park.

Anthropogenic and technogenic processes in the urban environment significantly change the chemical composition of the soil cover. One of such processes influencing the state of the urban soil is the process of soil cover pollution with heavy metals. Heavy metals are biochemically active and highly toxic; they are found in various components of the natural environment, as well as in systems of anthropogenic and technogenic origin. They have the property of accumulation in the body of living beings and have a negative effect on their condition. This group of chemical elements includes lead, zinc, chromium, mercury, copper, iron and other metals. Exceeding the permissible concentration of heavy metals in the soil of an urbanized area and their toxic effects pose a significant danger to humans. Contamination of the soil cover of an urbanized area with heavy metals is associated with the impact of a large number of sources of anthropogenic and technogenic origin, namely, energy and industrial facilities, city infrastructure support systems, zones of construction activities and storage of materials or waste. One of the main highly toxic chemical pollutants of the soil cover of the urbanized territory belonging to the group of heavy metals is zinc «Zincum-Zn». The article describes the results of a 2020 study of the current zinc content in the soil cover of the city of Astrakhan. The relevance of the work lies in the geochemical analysis of the content of heavy metals in the soil of the city of Astrakhan. The aim of the work was to study the modern process of soil contamination of the city of Astrakhan with zinc. The work was based on the task of determining the degree of exceeding the hygienic standards of the maximum permissible concentration of zinc in soil samples. Methods of geographical and ecological research were used in the work, soil samples were collected, followed by determination of the concentration of a substance in each of the soil samples in a certified laboratory. In the course of the work, the indicators of exceeding the maximum permissible concentration of zinc in the soil of the city of Astrakhan were determined and the presumptive sources of pollution were identified.

This paper deals with the problem of anthropogenic soil pollution of cities with oil production on the example of Novokuybyshevsk, Samara Region. To assess the modern ecological-geochemical state of soil cover in Novokuybyshevsk in August 2016 the field study was carried out and soil samples for laboratory analysis were selected. The study was carried out on 8 test areas, 7 of which were in different functional zones of the city, significantly differing in environmental conditions. The sample site was in a green area 10 km from the city. Soil samples were collected according to the methods generally accepted in soil science and Geochemistry. The quantitative content of oil products and heavy metals (Ni, Zn, Cu, Pb, Cd, Mn) in soil samples was determined in a specialized laboratory by certified procedures on the equipment, timely verified and calibrated. The data analysis revealed significant anthropogenic transformation of the soil cover in Novokuybyshevsk, which was enriched with petroleum and heavy metals. It also shaped the conditions that increased the migration of heavy metals in soils and their availability to biota. The soils of the city are characterized by relatively even distribution and high content of Zn and Cu. On the contrary, the Mn content is characterized by a rather low rate, which is especially evident for the soil sample area. The accumulation of Zn, Pb and petroleum products in the soils of the city is connected with the influence of the industrial zone. The motor component involves the contamination of soil by Ni, Zn, Si, Cd and petroleum products. No functional area in Novokuybyshevsk contains high levels of Pb concentrations, the content of which exceeded the MPC only in the industrial area. This fact can be associated with the ban of tetraethyl use in gasoline production in Russia in 2002. The obtained results can be used for environmental monitoring of the urban environment and predict changes of ecological-geochemical situation in Novokuybyshevsk in the future.

Pollution of the natural environment of the city with heavy metals (HM) from various sources receives much attention. They accumulate, exceeding the background level, cause pollution of the surface of the soil cover, vegetation, natural waters. It should be noted that their accumulation turns soils into a source of secondary pollution of natural environments and poses a threat to human health. In this regard, the monitoring studies, in addition to the traditional control of the HM content in soils, should assess the trend of changes in the level of pollution and their consequences. The object of research is soils, subject to varying degrees of anthropogenic burden. The analysis revealed a significant variation in all studied elements, which indicates a negative trend of their gradual increase. The average content of HMs was found not extreme but the rate of their accumulation raises concerns. An excess of MPC was found along highways (up to 500 m), from the railway (up to 20 m): Pb by 1.25–3 times; Cd - 1.65; Ni - 1.69-1.81; on the adjacent territory to the gas station by 1.37 times for copper, and 3.45 times for lead, which indicates the danger of pollution of the urban environment.
