Aim. Magnetic susceptibility is a fast, inexpensive and reliable technique for estimating and monitoring anthropogenic contamination of soil with heavy metals. However, certain factors affecting magnetic susceptibility need to be determined before applying this technique to environmental studies. The objectives of this study were to investigate: (1) the effect of parent materials and land use on magnetic susceptibility and concentrations of Ni, Pb, Cr, Cd, Cu and Zn; and (2) the possible use of magnetic susceptibility as an indicator of anthropogenic heavy metals contamination of soil in the city of Volsk, Saratov region, Russia.Material and Methods. Fifty (50) composite surface soil samples (0–10 cm) were selected. 1M HNO3 extractable concentrations of Ni, Pb, Cr, Cd, Cu and Zn were analyzed using atomic absorption spectroscopy. Concentrations of organic matter in the soil were determined. Magnetic susceptibility at low and high frequency (χlf and χhf) were measured and frequency dependent susceptibility (χfd) was calculated.Results. Magnetic susceptibility varied from 1.34 to 29.6 × 10−7 m3 kg−1. A positive strong correlation (P value = 0.01, r = 0.55) was obtained between Pb and χlf. Significant correlational relationships were observed between Pb with χlf, most likely due to significant effects of anthropogenic activities on magnetic susceptibility, therefore enhancing Pb concentrations in urban soils.Conclusions. In the soils studied, magnetic susceptibility could be employed as an indicator of anthropogenic contamination of soil with heavy metals.

Background. To study features of cereal grasses pollen collected in region were the enterprise that is in charge of destruction of the chemical weapons is placed - Gorniy, Saratov region. Materials and methods. Object of the research was pollen of cereal grasses collected in regions, differed by the ecological characteristics: object for destruction of chemical weapon of Gorniy of the Saratov region (investigated region), Privolzhsky area of the Ivanovo area (ecologically favorable region) and near to а motorway, Istrinsky area of Moscow Region (ecologically unfavorable region). Definition of the maintenance of heavy metals in pollen of grasses was carried out by the method of invertion voltamperometry, by percentage of sprouted pollen grains and the morphological characteristics of pollen grains by microscopy. Results. In samples of pollen collected within object for destruction of the chemical weapon of Gorniy, the maintenance of lead, mercury, zinc and cadmium, in comparison with non-polluting area, and with average values across the Russian Federation, thus lead almost ten times above, in comparison with average values of the maintenance in plants across the Russian Federation is authentically increased. The morphological changes of pollen more expressed in ecologically adverse region are revealed: the quantity of abortive pollen grains near to а motorway was above more than ten times, and, within the enterprise for the object for destruction of the chemical weapon of Gorniy, almost in 3 times, in comparison with non-polluting region. It is established that along with heavy metals (lead and zinc) which are а part of the list of the harmful substances containing in emissions in atmosphere of the enterprise for the object for destruction of the chemical weapon of Gorniy, the increasing of mercury and cadmium levels which are absent in а production cycle is revealed and can t be connected with enterprise functioning. Possibly other sources of pollution render.on the mercury and cadmium maintenance . Conclusion. Thus, in experiments it has been shown that pollen of plants possesses considerable sorbtion capacity for the heavy render metals which are а part of harmful production factors which change bioindicator properties of plant pollen and could form hypersensitivity.

Based on the analysis of statistical yearbooks "state of contamination of soils and objects of the natural environment of the Russian Federation with pesticides and toxicants of industrial origin", analysis of the incidence of workers and the population from exposure to residual pesticides and heavy metals, the need to assess soil contamination for organic farming purposes in accordance with the requirements of article 9 of the Federal law of 03.08.2018 No. 280-FZ "on organic products and amendments to certain legislative acts of the Russian Federation"is justified. For evaluation, a digital technology is proposed in the management of environmental safety and labor protection in agriculture, developed by scientists of the ITOSH-branch of the FGBNU FNAC VIM. It is proposed to solve the problems of detoxification of soils contaminated with heavy metals and residual pesticides identified during the assessment using the available domestic and foreign experience by various methods: physical, physical-chemical, and biological.

Tailings Ponds

Elevated contents of hazardous elements in natural ecosystems are often associated with human activities. Significant quantities of these elements, including heavy metals, are concentrated in tailings. The goal of the study was to assess the mineralogical and geochemical features of the old tailings of the decommissioned Krasnorechenskaya concentrating mill (located in Primorsky Krai, Russian Federation), which was processing complex tin-polymetallic and silver-lead-zinc ores, the chemical features of tailings pond waters, and the extent of environmental impact on the nearby Rudnaya river. In addition to the analysis of rock and water samples, the software modeling of the water-rock-gas system was carried out. In the study area, the minerals and rocks undergo changes that lead to the formation of highly mineralized, acidic waters saturated with various elements. In the tailings ponds, the maximum permissible concentrations were exceeded for Zn, Cd, Cu, Mg, Fetotal, Pb, Mn, Al, As, Co, Be, Sr, Ni, and Ba. The drainage from the tailings pond tripled the total mineralization of the Rudnaya river relative to the background values. However, the intoxication of the ecosystem by tailing products is partially inhibited by the secondary minerals in the tailings ponds. The negative impact is of a local nature, and 500 m downstream the concentration of many of the above elements is reduced. Despite this, the system that forms the chemical composition of highly mineralized waters is far from the equilibrium state. The oxidation of sulfides, dissolution of other minerals, and migration of oxidation and hydrolysis products will continue affecting the environment. In this regard, it is necessary to conduct environmental monitoring and undertake activities aimed at the recovery of mature concentration tailings or at suppressing the activity of hazardous elements by the conservation of tailings ponds.
