Assessment of the pyrogenic pollution of the soil-plant system on the base of geochemical markers for a local model of transport pressure

The choice of informative indicators for local estimates of the transport pressure on urban soil-plant systems is a serious problem of preserving green spaces. The spatial variations of the characteristics of the flows of marker compounds (polycyclic aromatic hydrocarbons (PAHs) acting as geochemical markers), the integral characteristics of the toxicity of soil pollutants, roots and aerial parts of plants TEQ, as well as the values of indicator ratios based on the concentrations of PAHs in the media are considered. The object of local research is the RUDN University campus (Moscow, Russia) with an adjacent forest park area. The territory is located in the zone of influence of heavy traffic flows and is experiencing an intense load from emissions. The state of the territory is monitored at 33 points according to a unique monitoring program. Pollution indicators showed different informativeness for constructing transport pressure models. Various modes of pollution in 3 functional zones of the territory are revealed; the zones of influence of the main sources of pollution are justified. The indicator ratios confirmed the leading source of pollution –pyrogenic emissions of transport, but they are to varying degrees sensitive to the activity of local pollution sources. Priority routes of PAH intake and accumulation in the components of the soil and plant system were identified. For the first time, a correlation between a number of ratios and indicators of polyarene contamination toxicity (TEQ) was established.

Development of geoinformation systems for environmental management and environmental safety in the areas of exploited oil deposits

The state of environmental protection of natural environment from negative processes has become an integral part of sustainable mining. The analytical review shows the ways of geoinformation system’s preparing a to ensure environmental safety during oil mining process on protected areas. Obtainment information for geoinformation database is based on technologies of aerial remote sensing, experimental modeling of biotic reactions to the impact of technogenic factors by biotesting methods. The geoinformation system should perform observations, assessments, search and regulatory forecasts, based on digital technologies, and develop individual measures for the preservation and restoration of the natural environment. Environmental stresses are usually caused by halogenesis, bitumization, air pollution and mechanogenesis. The use of geoinformation systems to collect information about the state of the natural environment is an essential feature of sustainable mining. Multispectral and panchromatic aerial photography by unmanned aerial vehicle has been successfully used to assess pollution, land degradation, and the effectiveness of land restoration. It is important to develop an unmanned aerial sensing technique for areas, where oil fields and protected are located. Biotesting of the consequences of technogenic transformation of ecosystem components is significantly related to the choice of optimal test objects for conducting experiments. Soil contamination with oil and its processed products affects the condition of all components: plants, microorganisms. It is advisable to develop a methodology for determining the patterns and levels of impact of residual oil and technogenic brines on local natural objects, local soil and water ecosystems based on the results of biotesting. Development of regulations for standard measures for remediation of ecosystems at different levels of pollution, during bitumization, halogenesis of land and water objects. The review shows that there are technological possibilities for creating GIS for monitoring the quality of the natural environment and environmental safety in the areas of oil fields. Digital maps of soils, watersheds, natural and technical systems, the development of technogenic processes and measures to restore the natural environment, allow to provide spatial modeling of natural and technogenic processes. Environmental quality management during oil mining process remains an important goal of geoecological researches.

Remote observation of animals by camera traps (example of the Vishersky reserve)

In 2016-2020 in the FSBI «State Reserve «Vishersky» (Perm Territory, Russia), observations of game animals were carried out, including the brown bear – Ursus arctos, the elk - Alces alces, the wild reindeer – Rangifer tarandus using camera traps. Camera traps of following models were user Keep Guard CK 076 HD Boskon Guard BG 520 Suntek (Owl 120), Scoutguard SG 562-BW (Boly Guard), Scoutguard SG - 2060-k, Bushnell Natureview Cam HD Essential mainly on animal paths. The total number of camera s was 4097 traps/day. On the basis of the results of remote sensing, the indices of the abundance of species were calculated, the seasonal and daily activity of animals was assessed, and the features of their behavior were revealed. According to the camera traps, the population density of brown bear does not correspond to the indicator for the optimal habitats of this species [8]. The western slope of the North Ural taiga in general and for the Upper Visher population of brown bears in particular such low this density is probably optimal. In total, 227 photolocations were obtained, of which 11 species of mammals and 2 spesies of grouse birds were recorded. The most frequently recorded species is the elk. It has been confirmed that with the formation of a deep snow cover, it leaves the protected area, whist was noted in the second half of the 19 th century [5]. Information on the age and sex composition of the moose group was obtained. The sex ratio was 1.8 in favor of males. Brown bear and elk are most active during daylight hours. To determine the indicator of the abundance of animal throughout the reserve additional data from camera traps installed in the main biotopes of the protected area required. At the same time, a network of camera traps is desirable following the example of the Central Forest Reserve [6] of the Kedrovaya Pad Nature Reserve and the Land of the Leopard National Park [11] with a network size of 5x5 km, where at least one observation point should be located.

Problems and prospects of involving waste from polymetallic and iron ore processing in biological conservation

Ore enrichment waste is a fine material that poses a serious environmental problem. However, the high residual content of rare and precious metals, as well as valuable metalloids, determines the preservation of technogenic formations as secondary mineral raw materials. This dictates the search for environmentally safe conservation of waste before its subsequent development. This report focuses on reducing the phytotoxicity of waste and the use of bioagumentation - the introduction of exogenous plant matter and azotobacteria into the root layer, which contributes to the optimization of the mineral nutrition of phytoconservants. The article examines the physical and chemical parameters of polymetallic ore dressing waste before and after chemical reclamation, provides information on changes in the composition of watersoluble forms of metal elements (Fe, Mn, Al, Cu, Zn, Cd, Co, Ni), a decrease in the anionic content of the sulfate ion, and the appearance of hydrocarbonates. It is experimentally established that after chemical reclamation of spent slags, their viability for seedlings of oats and white mustard increases. After reclamation, there is an increase in their morphometric indicators. Mustard reacts especially positively to the decrease in acidity and mobility of metals. The dry weight of its seedlings increases-by almost 30% compared to the control. When mustard seeds are inoculated with a suspension of a live culture of the bacterium Azotobacter chroococcum, its roots elongate and their weight increases. It is shown that the growth of mustard roots is also activated on iron ore processing waste that is subject to forest reclamation. But in such conditions, vital azotobacteria exhibit a glow, especially intense in small sand fractions. Chemolumi-nescent reactions ensure the survival of azotobacteria in the development of free radical reactions caused by the residual content of magnetic iron and lignin in the habitat. The revealed features of the growth of oat and mustard seedlings, as well as azotobacteria on ore dressing waste, should be taken into account when developing technologies to increase the biogenicity of the waste surface in vivo, to argue for the use of bioagumentation in creating technologies for environmentally safe waste conservation without involving the fertile soil layer - an irreplaceable natural resource.

Comparison of bog phytocenosis ecotopes parameters and peat deposit depths of the Beloe bog (Perm region, Russia)

It is known that phytoindication of the nature and depth of peat deposits is possible only when, among other factors, the geographical and geomorphological position of the bog systems is taken into account. The aim of this study is to determine whether or not there is a relationship between peat deposit thickness, phytocenosis composition and ecological parameters of plant habitats, using the example of the Beloe Bog located in the Sylvensko-Irenskaya lowland in the south-east of Perm Krai. Measure ments of the depth of the peat deposit were carried out using a peat probe, followed by the determination of the volumes of the peat bog in the GIS (ArcGIS (ESRI)). The diversity of peatland plant com-munities is described, their ecological-cenotic analysis and phytoindication analysis of ecotopes is carried out using Ellenberg and Landolt ecological scales using EcoScaleWin software. The results allow to update the stock data of geological exploration 1969. Ecological-cenotic and phytoindication analyzes revealed differences between pine-dwarf shrub-sphagnum and birch-menyanthes-sphagnum communities. A Spearman correlation coefficient demonstrated a relationship between peat deposit depths and the proportion of Water-Swamp ecological-cenotic group species in the communities, as well as with a number of ecological parameters of the ecotopes. The use of two different ecological scales revealed inconsistency between them. The article substantiates the chosen spatial tactics for measuring the peatland depth of a small irregularly shaped bog and also calculates the time required to measure the thickness of a conven-tional peat deposit of 1000 hectares. The relationship of this work to ongoing palaeoecological research in Perm Krai is highlighted. A comparison is made between the available data on the Beloe Bog and the results of phytoindication studies of the peatland thickness of Western Siberia known to the authors. The limitations and prospects of a series of similar studies in Perm Krai, which will reveal regional and zonal patterns in the spatial structure of bog communities and their relation to the thickness of peat deposits, are considered.

Review: emission and absorption of greenhouse gases by soils. Ecological problems

Soils are a source and sink of greenhouse gases (GHG) such as carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). Since the volumes of concentration and flux can be large, accurate quantitative estimates are needed to obtain the data on global GHG fluxes required for forecasting global changes and climate studies. This review shows the role of soils as one of the important sources and regulators of the content of CH4, CO2, N2O in the troposphere, and also presents the main methods for monitoring greenhouse gases. The influence of natural and anthropogenic factors on the emission and absorption of CH4, CO2, N2O by the soil cover has been analyzed. Original diagrams are presented showing the global fluxes of CH4, CO2, N2O by various ecosystems, including the pedosphere. The estimation of methane emission and distribution of its content in the main types of soils of the Rostov region is carried out. The mechanisms of CH4, CO2, N2O generation in soils and their possible influence on the calcium-carbonate balance, which plays an important role in the regulation of biogeochemical processes in the pedosphere, are considered. The performed analysis and generalization of research data on various types of soils makes it possible to shed light not only on their contribution to the global methane emission, but also to approach the understanding of processes and parameters that are important from the point of view of agrochemistry, such as, in fact, carbonate-calcium equilibrium and redox potential in modern soils. An inventory of sources and an assessment of the inter-reservoir gas mass transfer in the pedosphere - atmosphere system allows one to start developing a strategy to reduce greenhouse gas emissions that will help curb the rate of global climate change.
