Authors: Stepanova L P , Yelizarov N A , Pisareva A V 
Published: March 2021

Abstract
The article presents studies on establishing the influence of anthropogenic impacts on alluvial soils of agricultural lands. To solve the problem set, tasks were determined to estimate the degree of damage caused to soils of agricultural lands as a result of the soil humus layer loss or closure. These tasks included establishing the degree of alteration in soil fertility indicators for agricultural lands in regard to pH volume; organic matter content; degree of provision with K2O and P2O5 accessible forms as a result of violating technology of the damaged land stripping and reclamation. Nature of changes in granulometric (grain) and micro-aggregate soil composition is demonstrated. Study objects included agricultural land territories with soil samples of alluvial granular soil taken at the depth of 0-5 cm and 5-20 cm. Necessity is demonstrated to study in detail the agroecological assessment of land use systems and the development of differentiated measures ensuring reproduction of soil fertility, crop growth and territory ecological sustainability. Negative processes are manifested to a varying degree on agricultural land in most administrative regions of Russia including agricultural land in the Orel Region, which requires creation of the ecologically sustainable land use system. Since transformation of compounds entering the ecological system primarily occurs in the soil, which acts as a filter and as the factor of transformation and accumulation of the entering substances, agrobiological features of soil composition and properties make it extremely sensitive to anthropogenic impact. As a result of scientific research, it was revealed that the studied area experienced a decrease in soil fertility main indicators of the alluvial soils and destruction (deterioration) of the fertile soil layer as a result of exposure to anthropogenic influence. Rates of decrease in the organic matter content in soil layer as a result of the soil humus layer damage are shown. Significant fluctuations in the amount of exchangeable potassium in the soils of anthropogenically damaged agricultural lands are established. Degree of decrease in the amount of available phosphorus in soils without humus layer is revealed. Significant alteration in the granulometric (grain) composition of the damaged land soil is proved.

Published: March 2021

Abstract
The economic indicators of the development of the economy of the countries of the world and the presence of the ecology of the environment are significantly influenced by the points of location of power plants in large cities. In modern conditions, these points are recommended to be set taking into account the presence of cost factors in each large city. The use of these features allows you to minimize the emission of gases into the city. On the territory of the continent of Eurasia, there is a cargo point located in Kuzbass, in Russia. From this main loading point for coal on the railway network, loaded wagon flows are sent both in the western and eastern directions. The presence of this cargo terminal on the continent will have a significant impact on the rational location of CHP in large cities. The most rational will be the location of CHPPs, which will be located on the territory of large cities and located separately: both for the western and eastern parts of the continent. When energy streams move from the cargo-handling point, CHPs should be located at the entrance to the city. In the western part of the continent of Eurasia, it is more efficient to locate CHP in the eastern part of large cities. For the eastern part of the continent, power plants should be located on the outskirts in the western part of large cities behind the cargo-handling point.

Abstract
The spread of the dangerous Covid-19 infection caused by the SARS-CoV-2 coronavirus since the end of 2019 has become a big challenge for both the world and Russian society. Thus, on January 30, 2020, the world health organization recognized the spread of a new infection as a public health emergency of international significance. On March 11, 2020, the same organization stated that the outbreak had become a pandemic. Currently, the role of social and environmental factors (which determine the spread of many environmentally-related diseases) in the spread of coronavirus infection in the population is not fully understood. The spread of Covid-19 infection in Russia can be divided into 3 stages. Stage 1 (31.01.2020-01.04.2020) - primary distribution. At this stage, the infection occurred mainly of Russian citizens visiting other countries. Stage 2 (1.04.2020-12.05.2020) - active distribution within the country. By the end of this stage, the maximum spread of infection is recorded. Stage 3 (12.05.2020-present) - gradual decline in the appearance of new cases of coronavirus infection. To assess the specific contribution of social and environmental conditions to the spread of coronavirus infection, data from the Federal information Fund for social and hygienic monitoring of the Federal center for hygiene and epidemiology of Rospotrebnadzor on indicators of financial security of citizens, quality of health care and sanitary conditions were analyzed. Studies have shown that at the first stages, a significant contribution to the spread of infection is made by the financial security of the population. The specific contribution of the quality of medical care, which is widely differentiated within the regions of Russia, affects only the third stage of the spread of coronavirus infection. Environmental and hygiene indicators make a weak contribution to the spread of Covid-19 at all three stages of the epidemic.

Authors: Kotelnikov A V , Pyurbeeva Z Y , Kotelnikova S V 
Published: March 2021

Abstract
In the Astrakhan Region (Russia) on the bank of the Kizan River, which is a tributary of the Volga River, there are two oil sludge collectors, called “Sokolov pits”. They were created in the early twentieth century and now they are a major threat to the ecosystem of the delta river Volga. In this regard, it is topical to conduct studies to assess their environmental safety. The content of petroleum products and the biotoxicity of the soil in the territory of oil sludge accumulators are investigated. The seeds’ germination of watercress (Lepidium sativum) of plants was analyzed. During the study period (2017-2019) the dynamics of phytotoxicity of soils taken from the surface of oil sludge accumulators “Sokolov pits” was of an oscillatory nature. At the same time, the large phytotoxicity of the soil was abolished in 2017. On the territory of oil sludge accumulators “Sokolov pits” the greatest toxicity is the soil from the edge of the oil fields facing the river bank, the smallest is the soil from the edge, far from the shore. Thus, it can be noted a slight positive effect of the reclamation activities, the negative impact on the soil is not eliminated.

Published: March 2021

Abstract
The article provides a brief analysis of technological solutions for preparing rough feeds for feeding with an emphasis on the existing shortcomings in the implementation of the technological process, taking into account its technical support. There have been proposed and considered two technical and technological schemes for the preparation of rough feeds, the effectiveness of which is aimed at their rational use as a factor of low-waste technology and reducing the influence of a secondary factor when performing the considered technological process. The pollution of the airspace of the livestock building and the skin of animals with dust particles, including small particles of feed and microflora of dry food, can be considered as the very factor affecting the environmental safety of the internal space of the livestock building and indirectly the quality of products (milk). This is confirmed by the presented research results for separate technological operations.

Published: March 2021

Abstract
The purpose of the work is to identify the factors, features and problems of water use in the Central Black Earth Region. The Central Black Earth Region is characterized by longterm degradation of water resources, irrational water use, a low level of water purification, a high degree of pollution of water bodies, which requires a deep analysis of factors and trends in the development of the area’s natural resources. To achieve this goal, comparative, structural, statistical and analytical research methods were used. The information provided in the open official publications of the state statistics of the country and regions was used, in particular, the State Report “On the state and use of water resources of the Russian Federation in 2018” and reports on the state and protection of the environment of the Central Black Earth Region in 2018. In the course of the work, the data is systematized, structured, analyzed and summarized. The quality of water resources in the Central Black Earth Region is affected by the deterioration of the natural environment, including destruction of soils, a decrease in forest cover, and water and air pollution. Analysis of the development of water use shows us the complex ecological situation with the water resources of the region, characterized by a decrease in their volume. There are no rivers and reservoirs with “roughly clean” water in the Central Black Earth Region, water bodies of the 3rd category prevail, and there are even reservoirs of the 4th category of pollution. The water regime is deteriorating, fauna and flora are degrading. Taking into account the trends and features of modern nature management, on the basis of our work, we can conclude that the most effective direction of greening water use in the Central Black Earth Region is to reduce water consumption, purification of all types of runoff, optimization and afforestation of water protection zones.

Published: March 2021

Abstract
The environment of the Caspian Sea is considered internationally important because the Caspian Sea takes part in maintaining the global biodiversity. Monitoring the concentration of essential chemical elements in the organs and tissues of Caspian seal is an important task of protecting seal population, which makes the research topicality. Determining the metals was carried out by the method of atomic absorption spectroscopy using an MGA-915 MD atomic absorption spectrometer with electrothermal atomization.According to the research results, the chemical elements have been found unevenly distributed in the body of Caspian seal depending to the properties of metals and the functional characteristics of organs. Great concentrations of metals were recorded mainly in organs with active metabolic processes, and, on the other hand, in organs that actively participate in maintaining homeostasis, such as the liver, the kidneys, and the spleen.

Published: March 2021

Abstract
This paper described the development and application of a nitrifying bacteria sensor to monitor water toxicity. Four strains of bacteria with high efficiency nitrification, designated as F1, F4, Y2 and Z1, were isolated from fish pond sediment, and identified as Rhodococcus sp. (F1 and F4), Pseudomonas sp. (Y2) and Micrococcus sp. (Z1). The four bacterial strains were tested for their nitrifying capabilities. The results showed that the nitrifying rate of F1, F4, Y2 and Z1 reached 3.51, 3.43, 3.46, 3.52 mg/L·d respectively. The four strains were further cultivated for 21 days to investigate the effects of temperature, pH and inoculation amount on their NH4
+-N degradation ability. The cultivation showed that the four strains possessed optimal NH4
+-N degradation rate when temperature was 35?, pH value was 8.5, and inoculation amount was 30%. Furthermore, the carrier optimization test demonstrated that the nitrobacteria film prepared using 16% PVA, 1.2% SA, 2% NaNO3 and 75% CaCl2 had the best performance of toxicity detection. These results suggested that the nitrobacteria biosensor designed in this study was sensible and suitable for detecting water toxicity.

Authors: Wang Xiaoping , Lin Huanping , Yuan Dongya , Zhu Zhenzhong , Pei Lingmin , Zhang Jie , Sun Ya’nan , Zhao Qin 
Published: March 2021

Abstract
Salidroside is verified to have tumor inhibitory effects. Nevertheless, the mechanisms are not clarified. The research aims to explore the tumor inhibitory mechanisms of salidroside on gastric carcinoma. The tumor inhibitory effects were examined by the cell viability assay. Flow cytometric analysis was adopted to estimate the cancer cells apoptosis. The expressions of differentiated embryo-chondrocyte expressed gene 1 (DEC1), hypoxia-inducible factor-1α (HIF-1α) and signal transducer and activator of transcription 3 (STAT3) in carcinoma cells were measured by immunohistochemistry assay. Salidroside displayed definite cytotoxicity effects on gastric carcinoma cells in a dose and time dependent manner. Apoptotic percent in carcinoma cells treated with salidroside were significantly increased (P < 0.05). The migrations of cancer cells were suppressed with the increasing doses of salidroside. The expressions of HIF-1α, DEC1 and STAT3 in cancer cells with salidroside treatment were down-regulated. The findings suggested that salidroside suppressed the growth of gastric cancer cells by eliciting the cancer cells apoptosis and lowing the expressions of HIF-1α, DEC1 and STAT3 signal molecules.

Published: March 2021

Abstract
In order to study the spatial variability and influencing factors of heavy metals contents in five mangroves in South China, surface sediments and plant canopy new leaves of mangroves were sampled to determine Cr, Ni, Cu, Zn, Pb contents. Moreover, the corresponding pollution load index of sediments and bioconcentration factors of leaves were evaluated. Meanwhile, the physical and chemical properties, organic carbon and nitrogen of surface sediments and new leaves were measured. It was found that the average content of heavy metals in the surface sediments of Futian Reserve was the highest with a pollution load index of 2.61, classified as strongly polluted. The particle size distribution of the five sites was mainly silt-sand, and the pH was slightly acidic. Multivariate analysis of variance indicated that both sampling locations and vegetation types had significant influences on heavy metal contents in surface sediments and leaves as well as bioconcentration factors of leaves. In sum, natural factors such as plant species and organic matter contents significantly influence the metal contents and translocation in mangrove forests. However, in strongly polluted areas anthropogenic factors compromise the natural effects and play the major role in metal distribution.

Published: March 2021

Abstract
Using remote sensing images to extract the shoreline is an important means of studying coastlines. In this paper, we propose a semi-automatic coastline extraction method based on the coastline type that uses region segmentation and edge detection image processing. Based on selected Landsat 4-5 TM and Landsat 8 OLI_TIRS satellite images of Chongming Island from 1985 to 2017, we find that the point control method, neighborhood marking method, and targeted selection based on different shoreline types significantly improve the calculation efficiency, have good adaptability, and produce highly accurate shoreline extraction.
