Published: July 2022

Abstract
The developed waste management system in our country requires a radical and fundamental change from the final deposition to environmental technologies - recycling and disposal. The investigations represented in the paper perform the dynamics of changes in the methods of municipal waste handling in the Tyumen region. Over the period from 2010 to 2020, the population of the region went up 1.4 times and on January 1, 2020 increased to 1 537 416 people (excluding autonomous districts), and in Tyumen - 816.6 thousand people. With the rise of the population, the amount of generated wastes is also growing and accounts to about 2 million tons/year. The creation of industries for the treatment, disposal and waste processing is an urgent task for the development of the domestic economy, which is regulated by the legislative and regulatory legal acts of the Russian Federation and its subjects. One of the main reasons for the weakness in the implementation of waste treatment and further disposal processes is the lack of an organized effective system for the separate waste collection, as well as their subsequent treatment, disposal and waste processing on an industrial scale.
Prospects for the development of renewable energy for the energy supply of buildings in Russia
Authors: Alekhin V N , Sharovarova E P 
Published: July 2022

Abstract
The article considers the significance of the problem of renewable energy and energy saving technology development. The potential of solar and geothermal energy in the Russian Federation, the feasibility of using stable and inexhaustible renewable energy sources for implementation in buildings and structures are discussed. Construction, operation of buildings and structures consume up to half of all generated energy in the world. The efficiency of enclosing structures significantly affects the energy saving of buildings and generates up to 30% of heat losses. Using renewable energy technology in construction is effective with enclosing structures with high thermal insulation characteristics. Territories of the Russian Federation with decentralized energy supply, characterized by low consumer power, lack of access to power grids, lack of fuel, harsh climatic conditions, and low population density, have a high potential for the implementation of renewable energy sources (RES) into the buildings.
The effect of mineral fertilizers on reproduction of soil saprophytic bacteria
Authors: Sidorenko M L 
Published: July 2022

Abstract
The study of vital activity regulation of soil microorganisms is one of the general problems of soil microbiology. One of the factors influencing the existence and reproduction of bacteria in terrestrial ecosystems are fertilizers introduced into the soil. The effect of mineral fertilizers on the reproduction of bacterial complexes in soils of diverse types at different temperatures (4 ° C and 20 ° C) was studied. Mineral fertilizing promotes the active reproduction of saprophytic bacteria in calcaric cambisol (CCS) and distric cambisol soils (DCS). The variants with fertilizers can be arranged according to their effect on the reproduction of saprophytic bacteria in following order, regardless of the soil type: soil with nitric fertilizer > soil with phosphoric fertilizers > soil with potash fertilizer. Introduction of nitric or phosphoric fertilizers at 20 °C was more successful in CCS. It was found that application of mineral fertilizers positively affects the conservation and reproduction of bacteria in soils of diverse types. Prolonged application of mineral fertilizers reveals a positive effect on bacterial complexes, regardless of the soil type.
Applying best available techniques and best environmental practices to preserve ecosystem services
Authors: Morokishko V , Volosatova A , Ilina V , Vertyshev S , Malkov A 
Published: July 2022

Abstract
The study offers an analysis of two concepts used for reducing negative environmental impact: best available techniques and best environmental practices. The concept of best available techniques has been widely used for a long time and has proven to be an effective tool for implementing various regulatory mechanisms. Best environmental practices, on the other hand, have not been known for very long and their application is not yet widespread. Best environmental practices are only applied voluntarily; this fact distinguishes them from best available techniques which in most cases are regulated by legal acts. However, it would be a mistake to assume that best environmental practices are not particularly important within the framework of environmental regulation. On the contrary, their role is increasing, because any additional tools can not only help modernise industrial manufacturing processes, but also improve the image of the enterprise. The relevance of the study stems from the need to find solutions to preserve and restore ecosystem services. The concepts in question can serve as a framework for preventing further degradation of ecosystem services. The study has reviewed normative legal acts of the Russian Federation along with papers and monographs by researchers or experts in the field.

Authors: Samodolova O , Ulrikh D 
Published: July 2022

Abstract
Environmental pollution is one of the most serious problems that cities around the world are facing. Despite strict governmental policies in environmental laws and attempts by various countries to convert to closed-loop economies, the water, air, and soil pollution remains a pressing issue. One possible solution to this problem is to use phytogenic waste as a raw material for the production of sorbents to treat waste water. Recycling phytogenic waste in this manner solves several problems simultaneously: disposal of several tons of industrial and agricultural waste; increasing the effectiveness of water treatment; reducing the costs of water treatment; creation and use of an environmentally-friendly material. The article presents a complex study on the possibilities of using phyto enic waste from hemp production (hemp hulls) as a sorbent for the treatment of surface waste water in urban territories. The current state of the hemp industry and the prospects for its development are examined. A microanalysis of the composition of hemp hulls has been conducted on a JEOL JSM-6460 LV electron scanning microscope. The sorption capacity of hemp hulls at varying conditions has been examined.

Published: July 2022

Abstract
An interdisciplinary approach is used in the study of this problem. Well-known methods are used in the work. The ground-based phase of the research consisted of sampling. The results indicate intense pollution. High concentrations of compounds of mercury, arsenic, copper, lead, zinc were recorded. Deciphering the Landsat 8 (GloVis) images made it possible to supplement the mining and environmental monitoring by studying the dynamics of changes in the areas of placer gold mining. Data processing was carried out on the basis of the open geoinformation system Qgis. Image processing methods: False Color Composite (FCC) images in artificial colors; Band Ratio (BR) creates complex band ratios. Digitization of the images showed increasing areas of disturbed land. For the first time, a geo-ecological assessment using GIS technologies was carried out. Over a long period of time, ground monitoring data are entered into the Qgis database. The practical significance of the work is confirmed by the Patent of the Russian Federation and substantiated by the creation of a method to ensure the environmental safety of technogenically polluted areas using bioremediation.

Abstract
The protection and preservation of human health under present-day conditions of high urbanization rate is one of the priority tasks of contemporary construction. And here, the environmental safety of the residential buildings to be constructed is one of the most important factors. It is significantly affected by ionizing radiation for which radioactive radon gas is one of the sources. The level of public exposure depends on the concentration of radon in the aerial environment of outdoor territories and indoor spaces. The article considers the radon-related characteristics of the territories and indoor spaces in the Volgograd region and, based on the obtained results, provides calculations of the average annual effective equivalent doses of public exposure caused by radon and its daughter decay products in the region.

Published: July 2022

Abstract
Assessment of air quality is an integral part of the strategy to improve the quality of life and health of the population. According to the recommendations of the World Health Organization, carbon monoxide, nitrogen dioxide, sulfur dioxide, ozone, and particulate matter are subject to monitoring. Of particular interest are nitrogen oxides and ozone, which are characterized by an inverse correlation. The study is aimed at establishing the degree of this relationship according to the data of an automated monitoring system and assessing the level of air pollution in St. Petersburg, Russia. In addition, it is necessary to control the content of various specific compounds, including volatile organic compounds (VOCs). This is because public health impacts include exposure to both the VOCs themselves and secondary air pollutants resulting from chemical reactions between VOCs and other components. Thus, these substances are constantly monitored at observation stations in St. Petersburg. VOC monitoring provides for qualitative and quantitative analysis on measuring equipment with preliminary sampling and their preparation. Sampling uses various methods and devices. Based on the results of the theoretical and experimental studies, the authors propose the use of sampling devices, which differ from analogues in their design, metrological and operational characteristics.

Authors: Timofeeva S S , Tyukalova O V , Timofeev S S 
Published: July 2022

Abstract
The article considers antibiotics of the quinolone series, their using and mechanism of action. Based on the literature data, their application, distribution mechanisms, accumulation and behavior in environmental objects are considered. It is noted that the role of aquatic plants in the processes of biochemical degradation has not been sufficiently studied. Under the conditions of a laboratory model experiment, we studied the patterns of ciprofloxacin elimination by hydatophytes, i.e., aquatic plants completely submerged in water (Canadian pondweed, rigid hornwort, Eurasian watermilfoil). The spectral characteristics of ciprofloxacin were studied and quantitative estimates of the absorption of the antibiotic from solutions with submerged aquatic plants were made. We calculated elimination rate constants and phytoremediation potential. It was found that the rate of elimination of ciprofloxacin and phytoremediation potential depended on the type of aquatic plant and the initial concentration of the antibiotic. The highest elimination rate was found in models containing hornwort. Based on the data obtained, a conclusion was made about the prospects for the using of hydatophytes in phytopurification systems for post-treatment of wastewater from ciprofloxacin.

Published: July 2022

Abstract
Treated sewage wastewater is a possible alternative water source for increasing the water supply to the agricultural industry of the Republic of Crimea. However, their use, according to the results of research by domestic and foreign scientists, is constrained by a combination of a number of factors that need to be taken into account and analyzed before implementing this direction. The purpose of the work is to assess the possibility of using treated wastewater for irrigation purposes in the Republic of Crimea in modern conditions. The main source of this water category is large sewage treatment plants (STP) serving the cities of Alushta, Dzhankoy, Yevpatoria, Kerch, Saki, Simferopol, Sudak, Feodosia, Yalta. They account for about 80% of the volume of wastewater, discharged into surface water bodies annually. Based on the salt composition of the treated wastewater, the most promising alternative water sources for irrigation purposes are the STP “Ukromnoye”.

Published: July 2022

Abstract
In this work, the use of the sorption method is proposed for the purification of wastewater from ions of heavy metals. The aim was to study the sorption activity of diatomite in relation to cadmium ions. The studies were carried out under static conditions. The processes of physicochemical modification of diatomite for the extraction of cadmium ions from aqueous solutions were investigated. The influence of time and pH on the value of sorption was studied. The optimal conditions for sorption extraction have been determined. Adsorption isotherms have been constructed, and quantitative characteristics of the values of adsorption of cadmium ions on the surface of modified sorbents have been obtained. The fundamental possibility of using diatomites for the purification of cadmium-containing wastewater has been assessed. Based on the data obtained, it can be concluded that acid activation does not promote adsorption (even negative adsorption is observed), which confirms the mobility of cadmium in the low pH region, it can be assumed that only an increase in alkalinity to the possibility of formation of hydroxocadmium (CdOH)+. Thermal, shows stable adsorption in relation to Cd+2, which suggests the possibility of using such activation of cadmium diatomite and other metals, that is, with complex pollution.

Published: July 2022

Abstract
The basis of rational management of water resources quality on the territory of cities is to obtain complete and reliable information, reflecting the state of water bodies. This becomes possible only if the monitoring network is properly organized and balanced from an ecological and economic point of view. The fulfillment of this requirement makes it possible not only to obtain the data, necessary to assess current state of water resources, to make forecasts of changes in the qualitative indicators of river runoff, taking into account water availability of the year, level of anthropogenic load, but also in some cases to localize areas, where unauthorized discharges of pollutants are practised. In the course of this study, it was found that the monitoring network of observations of hydrochemical, biogenic indicators and physical properties of water within the boundaries of the Simferopol city district is organized irrationally. In order to increase ecological and economic efficiency of its functioning, it is advisable for monitoring organizations to agree on a list of monitored indicators, the number and location of observation posts, as well as to monitor the impact of the urban environment on the Slavyanka river.

Published: July 2022

Abstract
The paper presents research results for NOX reduction for moderate incomplete combustion, its impact on the environment and boiler reliability, optimal combustion conditions criteria, and its implementation in operating steam and hot-water boilers. The authors pay additional attention to the cost efficiency criterion while analysing the best method for reducing NOX. After conducting a numerical calculation for combustion processes under certain defined conditions, the authors suggest a new method for emission reduction by suppression of thermal NOX formation using the extended Zeldovich mechanism. Research shows up to 40% NOX reduction potential for existing boilers depending on fuel type and operating conditions with CO concentration in stack gases lower than standard levels due to chemical incomplete combustion.

Authors: Kolodezhnaya E V , Gorlova O E , Orehova N N , Kolkova M S , Glagoleva I V 
Published: July 2022

Abstract
Production and consumption wastes reduce utilization efficiency of natural resources and negatively affect ecosystems. More than 500 thousand hectares of land are occupied for the storage of mining waste in Russia, and the negative impact of the waste extends to territories exceeding this area by 10-15 times. Content of ferrous and non-ferrous metals in wastes of metallurgical and mining industries is comparable to content of these components in ores of promising deposits. Involving these materials in processing is an urgent priority. The most important factors determining the efficiency of processing are the selectivity of penetrating a valuable component, determining the optimal grinding size and the content of fine particles. The structure, material composition and physical and mechanical characteristics of metallurgical slags differ significantly from natural ores, so the disintegration schemes of man-made raw materials must be chosen for each material depending on its individual characteristics. The paper defines significant criteria for assessing the characteristics of the composition and properties of man-made raw materials for choosing the rational method of slag destruction according to the selectivity and energy intensity using the case of metallurgical slag.

Authors: Butakova M D , Ulrikh D V 
Published: July 2022

Abstract
A challenging situation has currently developed in the Russian Federation with the formation, accumulation, use, storage, and disposal of industrial waste. This has lead to environmental pollution, environmental abuse, and, as a result, significant economic damage. About 80 billion tons of various types of solid waste, including construction waste, have been accumulated in dumps and storage facilities on the territory of the country. About 7 billion tons of such waste is annually added to the waste already accumulated in the country. Such huge reserves occupy considerable areas near residential areas. Russia annually allocates about 10,000 hectares of usable land for solid industrial waste landfills and dumps. It remains unknown what areas are occupied by unauthorized dumps of construction waste. The paper presents the results of experimental studies on the use of floured silicate brick waste in the manufacture of highly efficient building products.
