The influence of exploitation and abandonment of coal mines of the mining complex of Lviv-Volyn coal basin on the ecosystem of the region is considered. The main ecological problems of the territory are analyzed. It is established that the high technogenic pollution of the Chervonograd geological and industrial region is facilitated by the inflow of highly polluted drainage waters from the mine heaps and rock waste heaps of the Chervonograd Central Mining Plant into soils, surface, ground and underground waters. The negative impact of the heaps is caused by the high level of fault tectonics and fracturing of the bedrocks, the flat surface of the area. The influence of technogenic objects on the atmospheric air quality is analyzed. The main causes of the atmospheric air pollution are stationary sources of pollution. Technogenic objects have a significant impact on the quality of the the atmospheric air. The main role in the structure of pollutants belongs to sulphur anhydrite, carbon and nitrogen oxides, dust and soot. The amount of pollutant emissions into the atmospheric air from stationary sources of pollution for Chervonograd and Sokal districts has been analyzed according to the data of the Main Statistics Office in Lviv region. To prevent further deterioration of the ecological situation, it is recommended to form flat heaps, their reclamation and landscaping with the obligatory covering of the surface with a layer of neutral rocks, to keep measures to prevent burning of heaps. To stabilize the situation and to prevent further contamination of soil, surface and underground waters, the stable network of observations on the state of the geological environment, systematic geological and environmental monitoring should be carried out.

The risk of chemical pollution is assessed by the level of its possible negative impact on the atmosphere, soils, groundwater and surface water, vegetation, animals and humans. The state of atmospheric air in Kharkiv and Kharkiv region is analyzed and it is revealed that atmospheric air pollution comes from mobile and stationary sources of pollution. One of the main sources of pollution is thermal power plants and oil and gas companies. The largest number of emissions from stationary sources is in Zmiiv, Krasnograd, Balakliia, Chuguiv districts and Kharkiv. The largest number of emissions from mobile sources is observed in Kharkiv and Derhachiv districts. The most polluted areas of the city of Kharkiv were identified, especially the central district and the area of the railway station, and the causes of pollution were established. As a result of comparison of the accepted maximum admissible concentrations of chemical substances in Ukraine, the USA and the countries of the European Union it is revealed that the Ukrainian norms are stricter. An analysis of emissions since 1990 found that their 9,14-fold reduction was due to a reduction in production and the closure of some enterprises as a result of the collapse of the Soviet Union. The sharp drop in emissions since 2013 is also due to the economic crisis and hostilities in eastern Ukraine. The reduction of emissions is explained not only by the reduction of production volumes, but also by the implementation of air protection measures carried out at the enterprises of the city and the region. There is a close link between pollutant emissions and gross domestic product (GDP) production, which can be used in the future to forecast emissions. Measures aimed at improving the state of atmospheric air in Kharkiv region and the city of Kharkiv are presented.

The purpose of this article is to highlight and analysis of trends in total emissions of polluting substances in atmospheric air of Mogilev region. The main material. A brief overview of Belarusian scientistsʹ research in the fi eld of geoecological conditions of atmospheric air is given in the article. The article deals with pollutants accumulation in the air of Mogilev region from various sources. Mobile sources (64.1% in 2015) are mainly responsible for air pollution in the region. In 2015 in comparison with 2010 there was a decrease in pollutant emissions as a result of transport functioning. Sources of pollutants accumulating in the air are exhaust gases from internal combustion engines, crankcase gases and fuel evaporation from fuel systems. Automobiles dominate in the structure of vehicles (85.3% in 2015). The article considers dynamics of pollutant emissions from stationary sources. The majority of pollutants are found in the air because of technological processes. Hydrocarbons and sulfur dioxide prevail in the structure of emissions of these sources. Chemical industry enterprises (Mogilev chemical fiber, Mogilev artificial fiber plant, etc.) are the sources of air pollution. Substances of the 4th and 3d danger classes predominate in the structure of pollutants in Mogilev region. Substances of the 1st and 2nd danger classes are insignificant. Conclusions. As a result of the conducted research uneven territorial distribution of emission density of the main pollutants in the air of Mogilev region has been established. Kostiukovich and Krichevsk districts are characterized by high level of emission density of suspended substances, carbon monoxide, sulfur dioxide in the air from stationary sources. Cherikov district is characterized by a low level of carbon monoxide, sulfur dioxide, nitrogen oxide emissions per unit area. 71.4% of the administrative districts of Mogilev region are characterized by an average density level of carbon monoxide emissions from stationary sources in relation to the average regional level, 14.3% of districts by lower level, 4.8% by low level and 9.5% by high level. It is advisable to improve the production technology, to equip enterprises with new gas cleaning facilities in order to reduce the anthropogenic load on the environment.

The oil industry is a leader in the negative impact on all areas of the natural environment. Polluting the atmospheric air, soil, surface and underground waters, oil production processes expose the population living in the adjacent territory to the dangerous effects of xenobiotics. The reproductive system is the most sensitive to environmental problems.The aim of the study was to identify the features of the intrauterine development of fetuses of women living in the territory of oil technogenesis in comparison with the fetuses of women living in a territory without it. A comparative assessment of the frequency of blastogenesis defects in the studied groups was carried out as a result of the analysis of embryological protocols of women who received infertility treatment using methods of assisted reproductive technologies. In order to assess the frequency and structure of defects in embryogenesis and fetogenesis, an analysis of cases of congenital malformations was carried out according to the data of the primary medical documentation of the Medical Genetic Consultation.The identification of differences in the development of embryos was determined by the Pearson agreement criterion. Assessment of statistically significant differences in indicators in the study of the frequency and structure of congenital anomalies in fetuses identified by ultrasound and in newborns, the structure of factors that influenced the mother during pregnancy, which could lead to the development of congenital anomalies and complications of the course of pregnancy, was carried out using t-Student's criterion. Defects of cleavage and blastulation of embryos of women in the observation group were revealed. It was found that the frequency of birth of children with congenital anomalies in the territories of oil technogenesis is statistically significantly higher than in the territories without it. In the observation group, congenital anomalies of the respiratory system detected by ultrasound examination of the fetus, congenital anomalies of the genitals, urinary organs, musculoskeletal systems, multiple malformations revealed antenatally are statistically significantly more common.

The aim of the article is to assess the impact of stationary sources of pollution of the Kyiv agglomeration on the state of its air basin. Atmospheric air pollution is known to be one of the leading elements in assessing the quality of human habitat because it has a detrimental effect on human health. The object of the study is the state of the atmospheric air of the agglomeration. The subject of the study is air pollution by stationary sources, identification of major pollutants, assessment of their man-made load on the air by emissions, by types of harmful substances, taking into account their danger by the values of maximum permissible daily concentrations and hazard class. Scientific and methodological support of monitoring tasks, comprehensive assessment of air pollution of agglomerations, both cities and their rural areas, is becoming increasingly important, especially where there are powerful stationary sources of air pollution. In the course of the research the enterprises – the main air pollutants of the agglomeration were identified, their emissions by types of harmful impurities were analyzed. The calculation of indicators of the hazard category of enterprises (HCE) on the volume of emissions, taking into account the values of the maximum allowable average daily concentrations and the hazard class of pollutants. To conduct a comprehensive assessment of man-made impact on the air, the calculation of the hazard indicator of the emission structure (HES) is proposed and their calculation is performed for certain enterprises. According to the proposed methodological approach, the values of aggregate indicators of man-caused load (MCLI) for stationary sources of pollution by numerical values of their HCE and HES are obtained. They comprehensively reflect the load on the air both due to emissions and due to the danger of harmful substances. Important measures to reduce volumes and improve the risk of emissions of harmful substances at enterprises are also indicated. Undoubtedly, promising methods are the study of air pollution in large cities and agglomerations, which are based on the use of geographic information technologies.

Purpose. Estimation of atmospheric air pollution level in the Dnipro city in modern conditions and technogenic loading on the air basin of the Dnipropetrovsk region. Methods. Statistical. Results. Volumes of pollutant emissions from stationary sources are 4 times more than emissions from mobile sources. The maximum values of emissions of pollutants are noted for the enterprises of the processing and extractive industry. The estimation of the level of air pollution in Dnipro city was carried out. An increase in the level of contamination in Dnipro city was indicated during the study period. Substances for which the quality of atmospheric air constantly does not meet the standards include dust, nitrogen dioxide and formaldehyde. The level of atmospheric air pollution can be classified as «polluted» and «highly polluted». The module of technogenic loading on the air basin of the Dnipropetrovsk region and Dnipro city was calculated. The rate of the technogenic loading in Dnipropetrovsk region from stationary sources considerably exceeds the mobile ones. In Dnipro city, the level of technogenic loading from stationary sources is an order of magnitude higher than the corresponding in the region. This indicates a significant level of technogenic loading on the Dnipro city air basin exactly from stationary sources. The volume of pollutant emissions from stationary sources in the region is an order of magnitude higher compared to the same in Dnipro city and the area of the region is two orders of magnitude larger. The reduction of the level of technogenic loading on the air basin of Dnipropetrovsk region as a whole was noted. Conclusion. Dnipropetrovsk region belongs to regions with significant industrial potential. The primary tasks for the improvement of the air basin are the development of measures to reduce emissions from stationary sources, as well as optimization of the monitoring system in order to determine the list of priority pollutants.
