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.

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.

The relevance of the work lies in the study of the process of pollution of the soil cover of an urbanized area with heavy metals. The aim of the work was to study the modern process of soil pollution in the city of Astrakhan with lead. The main task of the work was to determine the degree of exceeding the hygienic standards of the maximum permissible concentration of lead in soil samples. The work involved the methods of geographical and ecological research. The collection of soil samples was carried out, followed by determination in a certified laboratory of the concentration of a substance in each of the soil samples. In the course of the work, the indicators of exceeding the maximum permissible concentration of lead in the soil of Astrakhan were determined and the presumptive sources of pollution were identified. Under the conditions of the urban environment, under the influence of anthropogenic and technogenic processes, a significant change in the composition of the soil cover occurs. One of the processes that significantly affect the soil cover of the city is the process of soil pollution with heavy metals. The term heavy metals, as a rule, means metals (lead, zinc, chromium, mercury and others) that are found in various components of the natural environment and systems of anthropogenic and technogenic origin. Heavy metals are bio-chemically active and highly toxic. These substances are characterized by the ability to accumulate in the body of living beings and have a negative effect on them. The concentration of heavy metals in the soil of an urbanized area poses a significant danger to the urban population. The process of pollution of the soil cover of the city with heavy metals is associated with a large number of technogenic sources, which include energy and industrial facilities, systems for providing the city's infrastructure, zones of construction activities and storage of materials or waste. Lead «Plumbum - Pb» is one of the main pollutants of urban soil with highly toxic properties and belonging to the group of heavy metals. The article describes the results of a study of the current lead content in the soil of the city of Astrakhan conducted in 2020.

Abstract The effect of urbanization and industrialization in the urban city is soil contamination by heavy metals. This study was conducted to assess Pb, Cu, Zn, and Cd, in the soil of Yogyakarta city and its surrounding, Indonesia. The assessment was done by analyzing 45 surface soil samples in the study area, divided into three-zone. They are divided based on the distance of each zone to the center of the city. The zone III is located in the outermost of the study area, and zone I is inside the city. The results of the study showed that generally, the highest concentration of metals was located in zone I, which is located near or directly situated in a city center. The result indicated that Pb and Cd had the highest pollution index compared to Cu and Zn. The pollition load indeks (PLI) and geoaccumulation indeks (Igeo) calculations in the whole study area showed that the values demonstrated a moderate class in average. Special attention was needed to be given to the zone I, which has a higher PLI and Igeo index to reduce the source of emission for Pb and Cd.

The characteristics of the soil cover of the city Cherkassy and the sources of anthropogenic changes of its acidbase properties are presented. The results of the research of soils from different functional zones of the city Cherkassy showed that its reaction is mainly alkaline. The cartographic model of experimental data was made with the program SURFER showing acid-base regime characteristics of soils in different functional zones of the city. This mapping allowed to identify the following soils: fertile (рН = 6.5–7.0) and potentially fertile (рН = 7.0–7.5), hardly suitable (рН = 7.5–8.0), moderately (рН = 8.0–8.5) and highly (рН = 8.0–8.5) toxic. It is concluded that only 60% of urban soils can be identified as fertile or potentially fertile in terms of characteristics of acid-base regime. The results of the evaluation of acid-base regime of urban soilsare correlated with the results of the previous studies of pollution of snow cover in the areas of permanent emissions and the anionic composition of soils. The analysis of the cause-effect relationships in the impact of adverse environmental factors on urban landscapes showed that the formation of acid-base regime of soils is influenced both by the natural landscape, i.e. geochemical, and anthropogenic factors.

The present study used Pimelia latreillei as a biomonitoring insect for heavy metals soil pollution in a populated industrial area at Zawya Abd El-Qader, Alexandria, Egypt. Comet assay and histological analysis were applied to evaluate the potential risk of heavy metals. X-ray analysis of the soil samples collected from the polluted site revealed significantly increased metal percentages compared with the reference site. Moreover, a significant increase in metal percentages was detected by the X-ray analysis in insect ovaries collected from the polluted site. The Tail DNA length was significantly greater in the insects collected from the polluted site—47.6% compared with 11.4% at the reference site. Pronounced disruptions in oogenesis were observed through histological and ultrastructure investigations in insects collected from the polluted site. The study summarized the potential utility of insect biomonitors in predicting the effect of heavy metals soil pollution on occupational health.

Abstract The study is focused on environmental assessments of impacts by former briquette factory at the Nagymányok area in South Hungary. The (former) industrial zone is located in a northern valley of the Eastern Mecsek Mountains. Until the 1990s this company was the largest briquette factory in Hungary and the demolition works are still incomplete. former investigations were based on only five samples. our sampling sites were selected on the basis of the source of the contaminations and then we covered the whole area in equal distribution. We used the A1-F6 codes for the sample places. We have started from southwest to northeast. The samples were analyzed for Total Petrol Hydrocarbons (TPHs), Polycyclic Aromatic Hydrocarbons (PAHs) and for heavy metals. The area was heavily contaminated by TPHs and moderately heavy metals (such as Cu, Cr, Zn and Pb). Highest contaminant concentrations were found around the former industrial buildings, especially between the boiler-house and the coal-pillbox. In the industrial area the mean of the detected values is below the upper limit of the legal exposure values, but among the former industrial buildings higher (e.g. toxic level) concentration values were detected in multiple samples. Based on our investigation the pollutant can be transported by wind or by water on the surface (stream bed) or underground. The hazardous material can easily reach some part of the city, therefore reclamation is necesarry.

The statistically significant geochemical dependences of the dynamic behavior of petroleum products in urban soils in the fuel filling station zone are considered, the areal of their distribution are determined. The techniques used make it possible not only to identify laterally manmade modules of environmental hazard (laterally module) when oil products come from fuel filling stations, but also to determine additional factors of unaccounted environmental risk, for example, the process of accumulation of heavy metals in the soil profile in excess of the standards on the resulting geochemical barrier in the form of oil products. The risk assessment of oil product supply facilities should be carried out taking into account the specifics of the distribution of toxicants in technogenically altered soils.
