Technogenic soils result from the oxidation and hydrolysis of minerals in rocks extracted from mining areas and brought to the surface. Diagnostics of such soils involve a set of detailed tests, which can be both time-consuming and costly. In this study, the pH of sulfate soils in the Kizel Coal Basin (Perm krai, Russia) was determined using hydrog...

The results of ecological and geochemical assessment of the state of bottom sediments of small rivers in the city of Berezniki (Perm region) are presented, and the issues of environmental monitoring of small rivers of Verkhnekamie are identified. A comprehensive assessment of bottom sediment contamination is carried out. Their unsatisfactory condit...

This review provides information on the radiation situation in mining and energy production facilities. Mining activities are considered as one of the significant sources of radioactivity. Many radionuclides and metals that are transported by surface and ground waters, air flows over significant distances, contaminating soils, subsoil and bottom s...

Potash fertilizer production is one of the most important economic activities. Historically, potash mining has had a significant impact on the environment, often with catastrophic consequences. The purpose of this paper is to summarize the results of studies on the environmental impact of potash mining using the example of the Verkhnekamskoe potash...

Ochre particles in modern alluvium were studied in the area affected by the development of the Kizel coal basin deposits (Perm Krai, Russia) to establish their material composition. The purpose of this study was to determine the characteristics of the morphology and material composition of ochre particles, as well as their role as concentrators and...

Atmospheric deposition, vehicular transportation and de-icing agents are major sources polluted snow in urban. This study investigates the current trace elements concentrations of snow and de-icing using ICP-MS, and phytotoxicity using three vascular plants in snow. The study assesses the contamination, classification and phytotoxicity of snow qual...

This study considers the contents of natural radionuclides (226Ra, 232Th, and 40K) in the soils of natural–technogenic landscapes in the Verkhnekamskoe potassium–magnesium salt deposit (Perm Krai, Russia). The purpose of the study is to assess the lateral activity distribution of natural radionuclides (226Ra, 232Th, and 40K) in the soils of natural...

The purpose of the present study is to analyse the distribution of arsenic in the soils of the Verkhnekamskoe potassium salt deposit (Perm Krai, Russia). The danger of arsenic pollution is determined by its high toxicity and carcinogenic hazard. Being a technophilic element, arsenic enters the environment primarily as a result of mining activities....

The change in soil-forming processes and, as a result, in the ecosystem due to nearly 300-year long outflow of highly saline waters from ancient brine wells is considered for Perm Krai in Russia for the first time. The study area is located in the high floodplain of the Usolka River valley. Sodium-chloride ancient brine wells with mineralization of...

Over a long period of time, a huge amount of technogenic bottom sediments has been accumulating in the Kosva Bay with significant concentrations of amorphous iron and aluminium hydroxides, which, in turn, are active sorbents of pollutants. This study examines the distribution of trace elements (TE) and rare earth elements (REE) and their toxicity i...

The Kosva Bay is permanently affected by acid mine drainage (AMD) from Kizel Coal Basin in the Perm Krai of Russia. This discharge is released in the middle part of the Kosva River from the abandoned mines. This study investigates the current trace element (TE) concentrations for Zn, Cu, Pb, Ni, Cr, Cd, As, and Hg and the mineral composition, major...

The relevance. Soil-ecological potential of technogenic landscape among other components is determined by properties of lithogenic resource, which for mining areas are, primarily, heavy tonnage wastes – overburden rocks and mineral processing wastes. The purpose of this work is to assess the soil-ecological state of the natural-technical system of...

The recycling of various technogenic wastes involves the most important objectives of reducing environmental pollution and conservation of natural resources. This paper presents the study of the composition of rock dumps of the Kizel coal basin (Perm Region) which was examined for the first time for rare and rare-earth elements. The studies include...

The current study considered the distribution of trace elements in snow cover taking into account the functional zoning of the territory of Berezniki-Solikamsk industrial hub, Perm Region, Russia. The concentrations of 22 trace elements were determined in the dissolved phase of snowmelt using ICP-MS method. On the basis of on the background approac...

Methodical approaches to investigations of lithotechnical systems of mining-industrial territories, analysis of mechanism of natural and technogenic sedimentation as a factor of formation of technogenic grounds composition are considered. The work is based on the author's own long-term researches and published data.

Specific activity of natural radionuclides 226Ra, 232Th and 40K was measured by gamma spectrometry in samples of soil and bottom sediments of rivers on the territory of potassium salt deposit development in order to collect information on radionuclide distribution. According to the results of examinations, the range of 226Ra, 232Th and 40K activity...

The author considers approaches to an estimation of toxicity and potential ecological risk of the technogenic components in structure of river sediments of mining territories. We propose the use of an element lithotoxicity factor, which is accounted for by an additional multiplier to the ratio of the content of a single element in man-made componen...

In terms of anthropogenic impact of mining and processing enterprises, the adjacent territories are contaminated by upstream tailings dams. The contamination is developed by active seepage of liquid waste through the body of the dams. The authors have analyzed water balance at the Kachkanar Mining and Processing Plant tailings dump (Russia, Ural Re...

Significant seepage through tailings dams is one of the main disadvantages of upstream dams. In some cases, seepage through dams can lead to large water losses from recycling system of the dressing plant. Seepage evaluation should be carried out when designing of dams’ height increase in a framework of water balance prediction. In this chapter, the...

The development of coal deposits is accompanied by negative environmental changes. In the territory of the Kizel coal basin (Perm Region, Russia), the problem of contamination of water sources by acid mine waters and runoff from rock dumps is particularly acute. Mine waters are acidic (pH 2–3), with high mineralization (up to 25 g/L) and significan...

The authors consider the possibility of expanding the resource base of the Perm region using utilisation of the wastes of local industrial facilities. Feasibility of reuse of the wastes dumped by the Berezniki soda Plant, Uralkali Ltd, Motovilikha plants, Krasnokamsk Pulp and Paper Plant was analyzed. This article is based on the authors’ own resea...
