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.

Disposal of solid waste in landfills causes negative impacts on the environment, caused by emissions of greenhouse gases and the release of dark-colored leachate. It’s composition includes high concentrations of suspended solids, heavy metals, salts and organic compounds. Given the above, this study evaluated the use of superabsorbent polymer in the treatment of leachate. Slurry samples were collected at the Taubaté landfill in two seasons to determine electrical conductivity, pH, turbidity, oils and greases. Other samples were submitted to the following treatments: 3.5 g of polymer with 500 g of distilled water, and doses of 3.5; 7.0; 10.5; 14.0; 17.5; 21.0; 24.5; and 28.0 g of polymer with 500 g of slurry, with 4 repetitions each. Other steps, in sequence, were: transformation of the material into gel (gelation), obtaining the liquid volume of water and slurry, and after 0, 12, 24, 48 and 72 h, measurements of polymer dehydration were obtained. The efficiency of doses was determined by the volume of leachate remaining after each treatment. Gelation was more efficient in the summer season, a season with lower values of electrical conductivity, pH, suspended solids, and oils and greases. The most efficient doses in gelation were 10.5 g in summer and 14.0 g in autumn. In conclusion, superabsorbent polymer can be used in the treatment of leachate because it allows its gelling, but the recommended doses vary with the seasons.

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.

The accumulation of heavy metals and toxic elements in the topsoil horizon of urban areas is a big environmental problem as they could have long-term implications not only for the soils themselves but also on the human health and well-being. Many studies have shown that there is a clear relationship between the level of urbanization, volume of traffic, intensity of anthropogenic activities and heavy metal load. We aimed to analyze the accumulation of heavy metals at urban roadside soils and to assess the proportion of their mobile forms. The total content and mobile forms of Cu, Mn, Pb and Zn in soils samples collected along the main boulevards of Plovdiv (Bulgaria) was determined by two instrumental methods - ICP-OES and ICP-MS. The maximal concentrations were found in the Central and Eastern administrative regions of the city of Plovdiv. This finding well correlated with the wind rose characteristics and urban gradient theory. Our results revealed that the mobile forms of Mn represented 1.38-2.21% of total content and the mobile forms of Zn represented 8.48-11.81% of total content in studied urban soils. Mobile forms of Cu and Pb varied significantly and were in the range of 7.04-14.2% and 7.3-18.67% of the total content, respectively.

The Impact

This study aims to investigate the quality and vulnerability of surface water (Aries River catchment) in order to identify the impact of past mining activities. For this purpose, the pollution and water quality indices, Piper and Durov plots, as well vulnerability modeling maps were used. The obtained results indicate that the water samples were contaminated with As, Fe, Mn, Pb and have relatively high concentrations of SO42−, HCO3−, TDS, Ca, K, Mg and high values for the electrical conductivity. Possible sources of the high content of chemicals could be the natural processes or the inputs of the mine drainage. Generally, according to the pollution indices, which were correlated to high concentrations of heavy metals, especially with Pb, Fe and Mn, the water samples were characterized by heavy metals pollution. The water quality index classified the studied water samples into five different classes of quality, namely: unsuitable for drinking, poor, medium, good and excellent quality. Similarly, medium, high and very high vulnerability classes were observed. The Durov and Piper plots classified the waters into Mg-HCO3− and Ca-Cl− types. The past and present mining activities clearly change the water chemistry and alter the quality of the Aries River, with the water requiring specific treatments before use.
