This paper is dedicated to an integrated environmental assessment of soil cover in the Ivanovo Region’s territory. Using modern instrumental methods of analytical control has been determined a content of gross and mobile forms for Pb, Cd, Co, Ni, Zn, Mn, Cu and Fe in the soil. The analysis of the soils ecological state in the period from 2010 to 2014 has been performed. It has been found that the region soils are generally characterized by relatively low levels of heavy metals contamination. Areas with high concentrations of heavy metals’ mainly mobile forms are local ones. For the first time in Ivanovo region has been performed an assessment related to potential risk of soil contamination for the public health. Comparison of experimental results with statistical materials on morbidity and mortality, as well as the subsequent analysis of the obtained data together with the results of sanitary-hygienic research allow highlight the most contaminated areas, and identify potential sources of negative impacts, as well as to conduct ecological and hygienic assessment for investigated region’s soil status. Using of vivid cartographical techniques allows visually assess the scale of contamination for Ivanovo region’s soil cover, and reveal this information to the public in a timely manner.

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.

The accumulation of heavy metals, primarily from the soil, takes place in the water and fodder plants. Sources are pesticides, polluted air and precipitation. Hazardous chemical elements in certain quantities enter plants from soil. It should be added that ballast substances from mineral fertilizers containing heavy metals are also found in the soil. It has been established that on the flat-foothill massif of the North Caucasus, the constant component of solid precipitation are such elements as chromium, nickel, lead, manganese and silver. Cadmium was not detected in most precipitation samples (less than 1.0 µg / l), but its concentrations exceeded the maximum permissible concentrations by 4–8 times, although its sources were not identified. Therefore, an agrochemical survey of agricultural land has been carried out and it has been established that the content of mobile forms of copper and zinc in the soils of the foothill areas does not exceed the maximum permissible concentrations. Meadow grass stands do not accumulate zinc, copper, lead and cadmium in quantities exceeding the maximum allowable levels. In general, in the foothill areas of the Krasnodar Territory, hay contains 11.0–25.0 mg/kg of zinc, 1.8–9.0 mg/kg of copper, 0.2–2.0 mg/kg of lead, and 0.06– 0.24 mg/kg cadmium. Studies have shown that the agricultural soils of the foothill areas do not contain exceeding MPC values of mobile forms of zinc and copper. But there are local foci containing lead in small quantities. In hay from arable land and natural forage lands, the amount of heavy metals does not exceed MDU.

The distribution of heavy metals (HM) was analyzed in soils of Blagoveshchensk. The main physicochemical features (pH, the content of organic substance, mobile forms of phosphorus and potassium, the exchangeable cations of calcium and magnesium, as well as the total content of Cu, Cr, Ni, Co, Pb, Mn, Cd, Zn) were studied in soil samples. The anthropogenic influence on the urban environment transforms the physicochemical properties of soils: alkalizes the soil cover, increases the organic matter content, exchangeable bases, and mobile forms of biogenic elements. The total content of studied HM in the soils of Blagoveshchensk exceeds their concentrations in soils of the Mukhinka background territory and shows the spatial heterogeneity of pollutants distribution in the upper soil layer. As proceeds from the comparison of the studied elements concentrations with their MPC/APC, the most polluted territories are confined to industrial zones. Four elements, i.e., Mn, Pb, Cd and Zn, are accumulated in urban soils. However, Cu, Ni, Co, Cr accumulation is not so important. The calculation results of total contamination index in the upper soil cover layer in Blagoveshchensk taking into account the HM toxicity coefficient prove that Blagoveshchensk soils are mainly classified as moderately hazardous and nonhazardous. The evidence on the total content of HM do not allow making conclusion about their geochemical behavior in soils and about possible transition to neighbor environment. That is why the most mobile and easily mobilized forms of heavy metals, i.e., water-soluble and specifically adsorbed forms, were extracted using the method of successive extractions. The mobility of metals was established to be higher in the urban soils as compared to the background soils. Among the studied elements, Cd, Pb and Zn proved to be the most hazardous, with their mobility being close to the average risk of being included in the nutrition chains. This may lead to the contamination of Amur cross-boundary river ecosystems with heavy metals in case the groundwater level rises in the Blagoveshchensk territory due to its waterlogging by the Zeya River water.

Background: The transformation of natural elements, the migration of soil substances used in industry most often refer to metals, as a result of which “metallization” of landscapes occurs in industrial regions. Methods: The article proposes an analysis of studies, conducting agroecological monitoring of soil and plants in the zone affected by the action of Ryazan power plant in 2015-2019. Experiments included the analysis of the soil and climatic conditions of the area, sampling in the zone of five rings of the pipe of the polluting enterprise, the analysis of the content of some trace elements in the coal during combustion and the products of their combustion, as well as heavy metals in the biomass of the main types of plant communities in the zone of influence and mobile forms of metals in the soil of the zone, depending on the main directions of influence. Result: According to the results, the greatest distribution of mobile forms of heavy metals in the impact zone of Ryazan State District Power Plant (RGRES) was observed in the southern and southeastern directions in radii from 2.5 km to 30 km, in the southwest direction it was in radii from 500 m to 7 km and in the northern and northwestern directions it was within a radius of 500 m to 2.5 km from the station.

The article highlights the results of research on assessing the ecological state of the land near the silt fields №1 and №3 of Bortnytska aeration station in the Zolochiv village community of Boryspil district in Kyiv region. The presence of previously recorded increased content of heavy metals in soils compared to the background content, both in terms of their gross content and the content of mobile forms was confirmed within the certain areas near the silt fields. For the elements-pollutants (Zn, Cu, Cr, Pb) at some points within the agricultural land, exceeding the values ​​of their gross content and the content of mobile forms (Zn, Cu) of the maximum permissible concentrations was recorded at 1.1-6.2 and 1.1 -2.6 times, respectively. The average values ​​of heavy metals content for floodplains (settlement) and agricultural land near silt fields indicate their prevailing values ​​for the latter in almost all elements, as well as exceeding the background values ​​and maximum permissible concentrations for the land where silt deposits were previously applied as fertilizers. Within the surveyed areas, soils are classified as unsalted, but the increased content of exchangeable magnesium may adversely affect soil fertility. Increased mineralization and content of ammonium and nitrates in groundwater are observed near silt fields, which is obviously related to the impact of silt water and can lead to deterioration of groundwater quality in the area of ​​their transit and discharge, in particular within the village Gnidyn. The area of ​​land with an extremely dangerous pollution rate in terms of total heavy metal is about 300 hectares, with a dangerous pollution rate is 260 hectares, and the estimated damage from crop failure may be 1.65 million UAH/year and 0.3 million UAH/year respectively. Within the areas adjacent to the silt fields, the condition of soils, water resources, cultivated products and the health of the population should be constantly monitored, especially when using the polluted land for agricultural use or housing.
