Authors: Galaktionova L V , Terehova N A , Gavrish I A , Lebedev S V 
Published: November 2020

Abstract
Increasing release of a new class of pollutants (nanoparticles) into the environment necessitates studying the applicability of classical biotesting methods and identifying the features of their application. We conducted a study on a site located in the development zone of forest-steppe chernozems with an area of about 100 m2. The plot was divided into micro plots and nanoparticles. Zn solution was added to each surface at concentrations of 1000 mg/kg, 750 mg/kg, 500 mg/kg, 250 mg/kg and 100 mg/kg. In the course of field and laboratory studies, we identified germination, biomass and tolerance index of test cultures (Triticum aestivum, Raphanus sativus). A study of soil contamination with zinc nanoforms showed that the test plants Raphanus sativus and Triticum aestivum had different sensitivity to the effects of the toxicant. The germination rate showed the greatest dose-dependent dependence of Zn nanoparticles. Further growth and development of plants showed a gradual adaptation of plants to the effects of the stress factor and a gradual stabilization of the biomass and tolerance index.

Authors: Repkin R V , Lyubesheva A V , Pronina E L 
Published: November 2020

Abstract
The basin approach is the basis of this study of the factors of modern relief formation. Modern exogenous morphogenesis of landscapes of the river basin and its parts is not well researched. In this regard, the study of the dynamics of exogenous processes characteristic of the landscapes of the Klyazma river basin in areas with different types and degree of anthropogenic impact is relevant. Based on the results of field geomorphological studies, locations of modern relief-forming processes (hydromorphism, karst, ravine erosion, landslide formation, lateral erosion of rivers) that are most characteristic of the study areas have been identified and mapped.

Published: November 2020

Abstract
In this article, we will discuss the problems of high recreational pressure on beach areas, due to their deficit. Natural erosion of the coastal strip and other destructive processes, both natural and anthropogenic, lead to the need for an early and comprehensive analysis of the reviewed geosystems from different points of view. Comparison between the Azov and Black sea coasts of the Krasnodar territory reveals differences in the potential and dynamics of development of the tourist and recreational complex of these territories. Detailed segmentation and analysis of the status of beach areas was carried out according to the administrative division of the region. The paper analyzes questions related to the procedure for making certain managerial and organizational decisions that should have an effective impact on the work of the tourist and recreational complex. Coastal geosystems of the Krasnodar region have undeniable features and significance in contrast to other regions of Russia. In this regard, there is a need to divide the region into clusters.

Authors: Savinova S V , Bratkov V V , Klyushin P V , Lomakin G V , Musaev M R 
Published: November 2020

Abstract
The Caspian lowland desert is a plain slightly inclined to the Caspian Sea, which covers an area of 2,148,648 hectares and is divided into northern, more arid, with semi-desert landscapes (Nogai Steppe) and middle that covers the deltas of the Terek and the Sulak. These territories are routinely used for animal husbandry with a forage base to be attributed to climate conditions. In recent decades, there has been a widespread rise in air temperature with different trends in precipitation. These trends are estimated based on the datasets from the Makhachkala and Lagan meteorological stations for 1960–2018. Despite the current climate changes, the conditions for heat and moisture availability to support the vegetation period estimated by the hydrothermal coefficient generally remain quite stable and sometimes even more enabling for a sustainable forage base to be formed in the region.
To the characteristics of water-coastal flora steppe rivers of the central Caucasus

Published: November 2020

Abstract
When studying the vegetation of water bodies, it is necessary to pay attention not only to the vegetation of the water body itself, but also to the vegetation of the low part of its shores. Thus, we study plants with a different attitude to water: hydrophytes that are real aquatic plants, fully or mostly immersed in water. Hygrophytes, hygrophilous plants that live on excessively moist soil under neutral acidity conditions, are usually found in swamps, along the banks of water bodies, on the swampy soils of meadows and forests. The transition group between hydrophytes and hygrophytes is hygrophytes – amphibians or wetland plants (helophytes). They occupy both aquatic and humid habitats on the shores. Aquatic vegetation is divided into real aquatic and amphibian vegetation.

Published: November 2020

Abstract
Studies of the possibility of using wastewater from poultry enterprises for irrigation of light chestnut soils using sprinkler machines have shown that wastewater needs preliminary treatment. Currently, it remains relevant to search for the most effective and cost-efficient ways to treat wastewater. We propose wastewater treatment by sedimentation on natural zeolite, after which the treated effluents can be discharged into storage ponds for further use in agriculture using sprinklers. For sewage treatment, the settling method was used, before which the particle size distribution of zeolite tuffs was selected and the size of fractions was selected using sieves. The sedimentation was carried out at regular intervals on a natural sorbent (zeolite tuffs). As a result of the study, the optimal contact time of the natural sorbent with the studied effluents was selected, which allowed to reduce the concentration of impurities present to the value below the maximum permissible one. As a result of settling for 80 minutes, there is a decrease in the concentration of chemical impurities in the studied poultry runoff to the maximum permissible concentration. Irrigation with wastewater diluted in 1: 4 with pure water increased the yield of spring wheat compared to the control option by a factor of 1.5. The absorption of organic substances by a soil layer 0.6 m thick is 80-100%. Agricultural use of wastewater diluted 6-7 times provides additional net income from the cultivation of spring wheat by 40%.

Published: November 2020

Abstract
The paper presents the results of the analysis of geological and hydro-geological situation in the Krutinsky district of the Omsk region, as well as the assessment of the quality of groundwater in terms of environmental friendliness of their use for potable water supply. In hydro-geological terms, the research area is located within the Irtysh artesian basin, covering a vast territory in the south of the West Siberian lowland. The Cenozoic sediments that compose the described territory contain a number of underground reservoirs, horizons and water-resistant strata separating them. The waters of Quaternary, Neogene and Oligocene sediments are of practical importance as a source of water supply. Groundwater is exploited by wells and shallow waters (in Neogene and Quaternary sediments) are exposed and exploited by many shaft wells. The article provides a generalized characteristic of the quality of underground waters of Quaternary, Neogene and Paleogene deposits, as well as production wells drilled in the Krutinsky district of the Omsk region. As a result of research, it was found that groundwater does not meet the requirements of SanPiN 2.1.4.1074-01. The use of these waters for household and drinking purposes will be environmentally safe for the population only if such indicators as turbidity, color, chlorine, iron, dry residue and microbiological indicators are adjusted.

The results of laboratory tests have shown that all indicators exceed the permissible norm. This is due to an increase in precipitation in 2018 and 2019 and, accordingly, an increase in the level of water and flow of rivers feeding alluvial marches Al-Khaweze.
Extracting vegetable oils from model waters by sorbent on the base on carbonate sludge
Authors: Sverguzova S V , Sapronova Zh A , Spirin M N , Fomina E V 
Published: November 2020

Abstract
The peculiarities of sorption interactions between TMSP600 material obtained from carbonate sludge from sugar production and model sewage containing vegetable oils are investigated. It was found that in the absence of synthetic surfactants, TMSP effectively interacts with emulsions of vegetable oils and causes their rapid clarification. In the presence of sodium lauryl sulfate, efficiency is markedly reduced. The observed phenomenon is explained by the presence of a negative charge on the oil droplets, as a result of which they are repulsed from TMSP600 particles. The purification efficiency remains quite high at a synthetic surfactant concentration of <0.01 mg/dm3; therefore, TMSP600 can be considered acceptable for treating sewage contaminated with vegetable oils at a low synthetic surfactant content in the system.

Abstract
In 2008–2010, monitoring work in the national park «Smolensk Lakeland» showed an excess of mercury in the water of Lake Loshamye located in the protected area of the natural reserve. In 2014–2019, together with the staff of the national park, we studied the ecological and geochemical features of the catchment area and the water area of Lake Loshamye. We studied the patterns of distribution of several heavy metals: Hg, Cr, Mn, Fe, Co, Cu, Zn, As, Cd, Pb, Sr. We did not find an anthropogenic influence on the catchment area; this article presents the results of the study of the bottom sediments of the lake. As a result of the work, we determined that all heavy metals have a natural distribution in this lake, except mercury. High values of mercury in bottom sediments (up to 1000 ppb) are not typical for such natural object. The median of the sample is 152 ppb, and it is four times higher than expected mercury content considering its content in the soils of the catchment area and 2–5 times higher than the values obtained for similar objects by other researchers. The analysis of the patterns of mercury distribution in bottom sediments indicates a one-time, local anthropogenic pollution of the lake.

Abstract
The results of studies of environmental safety of a new organomineral fertilizer based on highly concentrated pig farm waste are presented. The effect of the fertilizer on spring wheat yield was evaluated. The vegetation experiment was carried out on spring wheat Zlata under phytotron conditions on sod-podzolic loamy soils. The effect of the organic mineral fertilizer, granulated bird manure and mineral fertilizers (NPK) in equivalent doses on toxicity and efficiency of biomass growth is compared. Based on the experimental data, the optimal dose of the new fertilizer was determined and the uselessness of higher doses was substantiated. The agro-reclamation value of the fertilizer produced by processing the reagent of liquid pig farm waste was substantiated. The effect of the fertilizer on the soil microorganisms was evaluated. For the diagnosis of group and partial species composition of soil microorganisms, the method of sowing on agar plates was used. The results of changes in the number of ecological groups of soil microorganisms are presented. It was found that organic fertilizer is not toxic and improves soil fertility.

Authors: Lebedev S V , Vershinina I A 
Published: November 2020

Abstract
Today, the attention of many researchers is turned to nanoparticles (NPs) and their use in practice. At the same time, nanoforms can exhibit toxic effects in relation to living organisms. One of the promising models for assessing the effect of nanoparticles is the E. fetida worm. In this regard, the aim of our study was to study the responses of the E. fetida worm in artificial soil with the introduction of NPs of Cu and CuO. In our work, we evaluated mortality, the mass of worms, the activity of antioxidant enzymes, and the content of malondialdehyde in the worm when introducing NPs of Cu and CuO at a concentration of 0; 50; 100 and 500 mg/kg of dry soil. In the course of our study, we found the stimulating effect of the minimum of the studied dosages of CuO NPs (50 mg / kg), which in the future may be of an applied nature. It has been established that Cu NPs have the highest toxicity, causing high mortality rates (80 %), a 50 % weight reduction (p ≤ 0.05) at a dosage of 500 mg/kg against the background of increased catalase activity and malondialdehyde content with a decrease in superoxide dismutase activity.

Published: November 2020

Abstract
Any floristic study, which gives an idea of the total number of species, is based on the distribution of flora by genera, families, orders, classes, etc. More than 2000 plant species grow in the Chechen Republic, which belong to 88 families and 460 genera. The republic is characterized by the alternation of different plant species from north to south. This paper analyzes the distribution of dendroflora species in the floristic regions of the Chechen Republic. The composition of wild representatives of dendroflora is peculiar and original and remains little studied. The analysis is based on the processing of herbarium materials and field observations.

Published: November 2020

Abstract
Visual signs of the negative influence of various factors in woody plants include the loss of decorativeness and vitality, discolouration of needles, uneven growth, etc. Conifers of the boreal zone, including Siberian fir (Abies sibirica Ledeb.), have the most pronounced decrease in the ability of plants of green plantations to resist extreme environmental conditions. In perennial plantations of Siberian fir, scientists identified a complex of fungi distinguished not only by low biodiversity but also by the abundance of phytopathogens and moulds from the genera Alternaria, Diplodia, Macrophoma, Pestalotia, Sclerophoma, Cucurbitaria. The article shows that under stressed conditions (imbalance in nutrients, etc.), the fir plants in the root zone have critical disturbances or mycological effects which characterizes the deterioration of their viability and loss of resistance to disease. This data are useful for phytosanitary monitoring of green plantations and planning environmental protection measures in urban areas.

Horse-chestnut leafminer Cameraria ohridella: invasion history and prognosis
Authors: Krivosheina M G , Ozerova N A 
Published: November 2020

Abstract
This work summarizes all known data on the distributive history of Cameraria ohridella in Europe and in Russia with special reference to current process of invasion to different regions of Russia and prognosis on its future spread through Russian territories. The invasion of the pest started in 1980s and to the present time Cameraria ohridella had occupied the most part of Europe. During last ten years from 2010 to 2020, Cameraria ohridella occupied 11 oblasts of the European Russia and was discovered in Kyrgyzstan and Kazakhstan. The main host trees of the pest are trees from the genus Aesculus. However, in the focus locations of invasion, the pest damages other trees growing near chestnuts. The data on biology of Cameraria ohridella showing that its larvae as a rule perish within the first two instars in case of development for example on Acer pseudoplatanus trees, give us confidence that the distributive range of the pest is restricted to the area of chestnut and locations of its decorative use.
