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.

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.

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 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.

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.

Metal Concentrations

Knowledge of variation in metal concentrations of playground soil in dry and rainy season could assist in controlling metal accumulation in children if playtime is regulated according to seasons. The present investigation was designed to find out the existence and trend of such variation. Thirty six surface soil samples from nine playgrounds of Owerri metropolis were collected during the dry season and rainy seasons of 2012 and 2013 and were digested in Pyrex glassware using nitric acid. Total heavy metal concentration was determined by AANALYST 400 Perkin Elmer absorption spectrophotometer and coefficient of variation was used to categorize variability. Results demonstrated significant seasonality for all five heavy metals with major variability observed between dry and the rainy season. Metal concentrations showed zinc as highest metal in both seasons whereas cobalt was lowest metal with Ni occasionally being lowest in the rainy season. The variation of metals concentrations in playground soil especially in the rainy season may add to the body burden of the children, and therefore reduced hours of play during this season is recommended.
