Abstract The aim of this study was to demonstrate that alluvial sediments of Wrocław ice-marginal Valley are characterized by higher con-centrations of metallic elements in relation to the adjacent areas of different soil cover genesis. Studies of zinc and arsenic content in soils were carried out in six municipalities of Średzki district. A total of 117 soil samples from arable land was collected: 80 from Średzka Upland and 37 from Wrocław ice-marginal Valley The process of accumulation of heavy metals in alluvial sediments in the Wocław ice-marginal Valley is so effective that, despite the heavier grain size composition of the soil cover immediately adjacent to Średzka Upland, zinc and arsenic concentrations are higher in the alluvial soils.

This paper presents the results of the research of soil contamination in flooded area located at the confluence of Bosna and Sava rivers. The sampling was performed according to a network of points Etrs89 reference European Network based on grid points of 500 m x 500 m. The total number of soil samples was 31 and 13 samples of sediment-mud. In the soil samples and sediment-mud samples various parameters were analyzed: pH H2O and 1 M KCl, humus (method by Tjurin), and the readily available phosphorus and potassium (AL method). The interpretation of total content of heavy metals in the soil was conducted according to Dutch Soil Remediation Circular (2009). The samples were analyzed for the total content of heavy metals: Pb, Cd, Cr, Ni, Zn, Cu (aqua regia digestion, AAS) and the elevated concentrations of Ni. However, Ni content in mud was from 240.5 mg/kg to 294.5 mg/kg, in soil it was from 128.9 mg/kg to 452.1 mg/kg. All mud samples were alkaline, and 79% of soil samples were alkaline and of neutral reaction. The analysis indicated that the flood in May 2014 was not caused by soil contamination with heavy metals, which however contributed to the increase of the overall content of these elements in the soil.

Abstract The aim of this study was to determine the content of arsenic in soils used for agriculture in the Ząbkowicki district. The content of arsenic in collected soil samples ranged 1.1-569.5 mg·kg-1. The standard for arable lands of Group B has been exceeded in 24 out of 231 test points. The highest concentrations occurred in the Złoty Stok commune. This is due to the output of arsenic and gold in this area. Exceeding the standard also occurred in neighboring communes: Kamieniec Ząbkowicki and Ziębice. This is due to the blowing and washing pollutions form the source of contamination, the arsenic mines in the Złoty Stok commune.

Abstract Nature and the environment are affected by various human industrial and/or urban discharges. Remediation for this problem requires first and foremost an in-depth analysis and an overall characterization of the intrinsic properties of the pollution-receiving environments. Secondly it is necessary to predict in these environments the behavior of dangerous chemical species (here particularly heavy metals) in the long term. This study focuses mainly on a detailed characterization of 4 soil samples sampled in vicinity of wild dump-BOULIMAT located 15 km west of the city of Bejaia-Algeria. The samples were characterised by atomic absorption spectrometry, X-ray diffraction, Fluorescence X and Infrared spectroscopy. The data showed high concentrations of metallic elements especially Zn (2,651.8 mg.kg−1) and Ni (163.44 mg.kg−1) in the soil samples. For their remediation, the stabilization/solidification (S/S) process with hydraulic binders appeared promising in reducing the polluting power of metal. This approach has considerably reduced the content of pollutants; 98 % removal was obtained for Ni and 99 % for Zn. The XRD analysis technique revealed the occurrence or absence of metallic elements in the crystallized phases.

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.

Heavy metals are among the most serious environmental contaminants in mining districts. Soil, as one of the main components of the environment, is the place of heavy metal entry into plants and consequently into the food chain, too. Potatoes grown in the region of Middle Spis (Slovakia) may be a source of increased content of heavy metals and pose a health risk to the consumer. The contents of heavy metals (Cd, Pb, and Ni) in potato and soil samples were determined using the AAS method and compared with limit values set by the Slovak Republic and the European Union. The content of heavy metals was determined in 12 potato cultivars with different length of vegetation period (mid-early, very early, and early, resp.), which were grown in three localities with a highly disturbed environment. Total contents and mobile forms of heavy metals as well as physical and chemical properties were determined in soil samples which were collected from the same sampling sites. Only Pb content in potato tubers was higher than the hygienic limit value (0.1 mg kg−1 FM) in 15 sampling sites (interval was n.d. –0.2298 mg kg−1 FM). The contents of exchangeable forms (total content) of heavy metals in soil were ranged between the intervals: Cd 0.004–0.055 (0.94–1 56), Pb 0.023–0.295 (17.00–26.80), and Ni 0.019–0.475 (30.80–71.00) mg kg−1. At current average consumption levels of potatoes, tolerable weekly intake (TWI) or tolerable daily intake (TDI) for observed heavy metals was not exceeded.

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.

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.

The Problem of soil and plant pollution by heavy metals in Slovakia is evaluated in this study. The measured data on the main risk elements have been obtained from a soil-monitoring grid in Slovakia, which consists of 318 agricultural sites. Analytical procedures of Cd, Pb, Cr, Ni, Zn, Cu (extracted by 2 mol/l HNO<sub>3</sub> and by 0.05 mol/l EDTA) as well as the total content of the described elements including Hg have been used for soil samples. Also the plants collected at the same sampling sites were analysed for their Cd, Pb, Cr and Hg contents. On the basis of the obtained results it may be concluded that significant pollution was determined only on 0.4% of the total soil cover in Slovakia. The significant correlation was determined between the soil available heavy metal content (extracted by 0.05 mol/l EDTA) and plant content. Potentially toxic elements were accumulated in the plant biomass only on heavily polluted soils
