INTEGRAL ASSESSMENT OF ANTHROPOGENIC PRESSURE ON WATER BODIES IN THE LAKE BAIKAL BASIN

The integrated assessment of the ecological state of the main rivers of the lake Baikal basin - Verkhnyaya Angara, Tyya, Barguzin, Selenga, Snezhnaya, Bolshaya Rechka, Khilok, Chikoy is based on the assessment of the variability of the basin system under the influence of two groups of indicators: 1) Direct (immediate) impact - the volume of water intake and wastewater discharge, water use and sequential water supply. Assessment of the impact on the state of the above-listed rivers basins from wastewater was performed using the algorithm proposed by A. Korolev et al. (2007). 2) Indirect (mediate) impact - indicators of areal and linear-network impacts on the catchment area. Based on the calculation of the integral anthropogenic pressure on the territory of the above-listed river basins, only the Selenga river experiences an “average” anthropogenic load. On the territory of most river basins, the anthropogenic load is “lowered” and “low”.

FORMATION OF HUMAN RESOURCES POLICY AND LABOR POTENTIAL OF THE MELIORATIVE INDUSTRY OF THE AGRICULTURAL INDUSTRY OF THE RUSSIAN FEDERATION

Scientifically substantiated personnel industry policy contributes to the implementation of an innovative development scenario, provides better results with reduced production costs, which determines the relevance of the studying. The main goal of the work was identified factors and indicators which have regulatory influence on the state and development of the personnel potential of the industry. Diagnostics of the labor potential of land reclamation by federal districts revealed leaders and outsiders of sectoral development. The studying made it possible to justify the steady trend of the shortage of reclamation personnel in comparison with the calculated indicators. Objective and subjective reasons and factors that hinder the effective using of the industry’s personnel potential are distinguished. The concept of industry’s labor potential is clarified. The studying of changes in labor productivity in agriculture has confirmed a twofold increasing in this indicator for the period from 2014 to 2018. Methodological approaches to the indicators of assessing the labor potential of the reclamation industry are substantiated. The groups of socio-economic indicators of the reclamation industry’s effectiveness are identified. The methodology for determining the quantitative characteristics of labor potential on irrigated lands is specified, which is depended on the area of irrigated lands. The labor potential of the reclamation industry in terms of staffing the industry is studied. The main positive and negative trends of the personnel policy and the labor potential’s formation of the agro-industrial complex’s reclamation sector of the Russian Federation are specified, the industry personnel policy is assessed as passive, which does not allow predicting the needs for industry personnel, evaluate staff activities and analyze personnel problems. Highlighted characteristic trends in personnel potential in the federal district and regions of the Russian Federation allow: to develop unified approaches to manage this industry development factor; to develop recommendations to improve the efficiency of advanced training and retraining of personnel in irrigated agriculture. The implementation of the recommendations will contribute to increase the efficiency of the managing the human potential’s process of irrigated agriculture at the level of federal, regional and municipal authorities of the reclamation sector of the agro-industrial complex of Russia.

FACTOR ANALYSIS OF GEOGRAPHIC COORDINATES AT POINTS OF THE CHANNEL OF A SMALL RIVER ON SPACE IMAGES

The purpose of the article is the analysis of asymmetric wavelets in binary relations between three coordinates at 290 characteristic points from the source to the mouth of the small river Irovka. The hypsometric characteristic is the most important property of the relief. The Irovka River belongs to a low level, at the mouth it is 89 m high, and at the source it is 148 m above sea level. Modeling of binary relations with latitude, longitude, and height has shown that local latitude receives the greatest quantum certainty. In this case, all paired regularities received a correlation coefficient of more than 0.95. Such a high adequacy of wave patterns shows that geomorphology can go over to the wave multiple fractal representation of the relief. The Irovka River is characterized by a small anthropogenic impact, therefore, the relief over a length of 69 km has the natural character of the oscillatory adaptation of a small river to the surface of the Vyatka Uval from its eastern side. This allows us to proceed to the analysis of the four tributaries of the small river Irovka, as well as to model the relief of the entire catchment basin of 917 km2. The greatest adequacy with a correlation coefficient of 0.9976 was obtained by the influence of latitude on longitude, that is, the geographical location of the relief of the river channel with respect to the geomorphology of the Vyatka Uval. In second place with a correlation of 0.9967 was the influence of the height of the points of the channel of the small river on local longitude and it is also mainly determined by the relief of the Vyatka Uval. In third place was the effect of latitude on height with a correlation coefficient of 0.9859. And in last sixth place is the inverse effect of altitude on local latitude in the North-South direction.

GRAFTED TOMATOES – ECOLOGICAL ALTERNATIVE FOR CHEMICAL DISINFECTION OF SOIL

This study aimed to identification of an ecological alternative for the chemical disinfection of soil in the greenhouses from Romania. Tomato (Solanum lycopersicum L.) is one of the most popular vegetable crops in the world. The carbohydrate, vitamins, salts of important mineral elements and organic acids content of tomato fruits is very important. Tomato crops are very sensitive to climatic vagaries, so fluctuation in climatic parameters at any phase of growth can affect the yield and the fruit quality. Grafting on Solanaceae is a method which has improved and spread quickly during the past years, a similar approach to crop rotation, a practice meant to increase productivity, resistance or tolerance to biotic and abiotic stress factors and at increasing fruit quality. The research was conducted in a glass greenhouse of the Horting Institute, Bucharest, Romania. The biological material used was a Romanian tomato hybrid (Siriana F1), a Dutch tomato hybrid (Abellus F1) and four rootstocks, a Dutch tomato hybrid (Emperador F1) and three Romanian tomato cultivars (L542, L543 and L544) obtained from the Research and Development Station for Vegetable Growing, Buzău, Romania. The rootstocks have had resistance to biotic stress factors (soil diseases and pests) and the chemical disinfection of soil has was eliminated. The result of this research are presented in this paper.

POTENTIALLY TOXIC CHEMICAL ELEMENTS OF SHALE PLAYS – ECOLOGICAL THREAT TO THE ENVIRONMENT

This research considered the content of trace elements (TE), including potentially toxic elements (PTE) in shale plays and deposits in various regions of the world. Their comparative analysis was carried out and the highest concentrations of PTE in the shales of some regions were revealed. The author notes that the destruction of organometallic compounds occurs during the development of shale hydrocarbon (HC) using horizontal drilling with hydraulic fracturing – injecting large volumes of chemicals while increasing the temperature. During such destruction processes, PTE can escape into the environment: into groundwater, soil layers, and other objects of economic use, and also deteriorate well equipment. In connection with the noted environmental hazards present during the development of shale HC, this paper proposes to monitor the content of TE in both shale rocks as well as in extracted shale oil in order to mitigate the risks of their release into the environment. In addition, developers and scientists should consider the losses of industrially significant volumes of valuable metals that occur due to the lack of cost-effective technologies for their capture and extraction from naphthides.

ON THE REGIME OF COVID-19 EPIDEMIC IN RUSSIA AND ITS IMPACT UPON THE FUEL AND ENERGY COMPLEX, INCLUDING IN EDUCATIONAL AND SCIENTIFIC SPHERES

The mode of development of the COVID-19 pandemic in Russia and the impact of the epidemic on the areas of scientific research, education and functioning of the fuel and energy complex are discussed. The official statistics revealed evidence both of effectivity of the taken anti-epidemic measures in Moscow and of possible cases of incorrectness of statistical data. The social situation and the mode of development of the epidemic in Moscow and in the regions of Russia are essentially different, that reduces the effectiveness of anti-epidemic measures introduced uniformly throughout the whole country. The conditions of the pandemic and quarantine are difficult for everyone, but organizations and persons with a more modern informational character of production adapt to them more easily. In general, it can be suggested that the epidemic besides the very essential losses gives an important impulse for social-economic and political modernization of the society.

SMOG IN BIALYSTOK IN POLAND. DATA OF PM 2.5 AND PM 10 PARTICULATE MATTER IN OUTDOOR AIR MEASURED IN 2017-2018 BY "THE LABORATORY OF ENERGY-EFFICIENT ARCHITECTURE AND RENEWABLE ENERGIES" AT FACULTY OF ARCHITECTURE OF BIALYSTOK UNIVERSITY OF TECHNOLOGY

The differences between what in the winter 2017 was presented by the government measurement station of air quality, belonging to the Chief Inspectorate of Environmental Protection (CIEP) in Bialystok in Poland, and what the citizens could see and smell, were the reason for installing the monitoring system of PM10 and PM2.5 particulate matter, in the "Laboratory of Energy-efficient Architecture and Renewable Energies" (LEARE) at the Faculty of Architecture of Bialystok University of Technology. The measurements were compared with done by CIEP and the information of “The World Air Quality Index” (WAQI). This project started in 2007. It is proving a transparent Air Quality information for more than 70 countries, covering more than 9000 stations in 600 major cities. Since 16 Nov 2017, data was also downloaded from the new European Air Quality Index (EAQI) website, created by the European Environment Agency (EEA). From the beginning of 2018, data from the public-private service AIRLY was added to the study. They installed four online dust meters in Bialystok. The density of the dust measurement network was still insufficient, so the mobile measurements were started. Recently, the use of a drone equipped with a dust meter for tests at various heights has begun. Measurements denies EAQI presentation of so good air quality in Bialystok. The levels of PM2.5 and PM10 are often much higher than those presented by EAQI and CIEP. Government measuring station, located in the center of Bialystok, poorly reflect air pollution in peripheral districts.

THE CONSOLIDATION OF SOFT CLAY FOUNDATION GROUND USING GEOSYNTHETICS COMBINED WITH THE ELECTRO-OSMOSIS PROCESS

In the last decade, the construction of communication routes has intensified in Romania. As a result, many case studies related to the presence of saturated clayey soils in the foundation ground have emerged. In order to speed up the execution of highways and railways in a safely manner, the designers use different methods of improving soft clays in terms of compressibility. The present study aims to evaluate the efficiency of an electrical current used for the vertical dewatering of a soft clay subgrade, through simple physical models. The experimental study is being performed on a laboratory scale model by using electrodes and geosynthetics for drainage, along with the vacuum technique. The vertical drainage capacity during the electro-osmotic dewatering process, combined with preloading, drainage, vacuum and heat induction is being evaluated. The integrated effect of these methods on the consolidation process will be analyzed for the final conclusions.

ORE CONCENTRATIONS OF METALS IN NAPHTHIDES OF HYPERGENESIS ZONE: ASSESSMENT AND ENVIRONMENTAL ASPECT

The study examines the formation of secondary-altered crude oils associated with the processes of modern or ancient hypergenesis. As a result of geological processes during intense upward movement of the earth's crust, oil undergoes physical weathering, inorganic oxidation, washing out with water, biodegradation and sulfurization, and turn into heavy oils and hard bitumen. In zones of hypergenesis, the loss of light fractions occurs and the absolute concentration of trace elements (TE) associated with resinous-asphaltene components, such as V, Ni, Co, Mo, Cr, Cu, etc. sharply increases. In addition, oils absorb elements of variable valence (V, Fe, U) from low-salinity stratal waters. As a result of experimental studies on the interaction of oils with low mineralization waters, which are characteristic of hypergenesis zones, leaching of some elements (e.g., Zn) from oils and absorption of others from contacting waters (for example, concentrations of newly-formed organometallic compounds V and Fe increased by 1.3-12 times) were found. The author utilized the method of neutron-activation analysis to study the content of TE in oils and natural bitumens of the Volga-Ural, Timan-Pechora, Kazakhstan, Tajikistan, and etc. Ore-level concentration values were found, for example: 180-1162 ppm for V and up to 100 ppm for Ni in the oils of the Melekess depression in Tatarstan, and 940 ppm for V and 130 ppm for Ni in the oils of Kazakhstan deposits. Classification of oils by the content of “biogenic” elements V, Ni, Fe and by physical and chemical properties revealed significant differences of hypergene-altered oils in the general cycle of genesis of naphthides. Deposits of secondarily-altered oils are found in a wide stratigraphic range in oil and gas basins of various geostructural types in traps of the combined morphology – lithologically and tectonically shielded. During the development of oil deposits that contain high concentrations of TE, it is necessary to take into account ecological aspects. The environmental aspect is due to the fact that many metals contained in oils – V, Ni, Cd, As, Hg, U, etc. belong to highly toxic compound chemicals.

MAPPING THE MINERAL RESOURCES DATA OF WEST BALKAN REGION INTO EXISTING EUROPEAN DATA MODEL

Primary and secondary mineral resources are of strategic importance for the EU. Most EU countries (including Slovenia) are already part of the pan‐European Minerals Intelligence Network which provides consistent and organized data information on primary and secondary mineral resources on the European level. It was established in previous projects as EuroGeoSource, Minerals4EU, ProSUM, Mica and ORAMA. The Eastern and south Eastern European (ESEE) region represents a gap in this network, but at the same time is also identified as one of most important strategic regions for the EU with great potential for mineral supply. The large concerns are aiming to expand their business to the region, but access to relevant data interesting for the investors is still not available. There is a need for surveyed and unified mineral resources data. In the framework of RESEERVE (EIT RM KAVA project, duration 1.4.2018-31.3.2021), national mineral resources data of six task partners from West Balkan countries (Albania, Bosnia and Herzegovina, Croatia, Serbia, Montenegro and Macedonia) were implemented and harmonized with INSPIRE directive (European directive for organizing spatial data). Since EU directives are mandatory for members only and West Balkan countries are not yet targeted (except Croatia), they are still interested in their implementation. For that reason the main project goal is the creation of the West Balkan Mineral Register, provided by national data providers, which will represent a starting point to integrate the ESEE region into existing EU data platforms and bring it closer to common minerals market. Regional mineral data will become more accessible and relevant. The goal of the project is to anticipate the future supply and demand for minerals, particularly regarding critical minerals and therefore to contribute to the sustainable mineral supply in Europe. Leading partner for RESEERVE project is Geological Survey of Slovenia (GeoZS), which has identified relevant data providers and examined data quantity, quality and format. GeoZS will synthesize primary and secondary raw material data into common West Balkan Mineral Register and test the harvesting of data in INSPIRE compliant European data model. The scenarios drawn up in the project will be available through the European Geological Data Infrastructure (EGDI), which will offer easy access to existing mineral data. EGDI provides access to Pan-European and national geological 150 datasets and services from the Geological Survey Organizations of Europe. Through EGDI data from several European data harmonization projects are accessible. EGDI was launched in June 2016 in a Version 1 and has since then been extended to include more data sets, including mineral resources. The article is mostly focused on workflow harmonizing the data and spreading IT knowledge of mapping the national primary and secondary minerals data to already existing European data model and developing national relational databases, that fit into European common database structure. Data harmonization was already performed through national training workshops to assist task partners in taking the first step toward INSPIRE directive implementation.
