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 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.

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 main sources of anthropogenic emissions into the atmosphere of Murmansk are emissions from thermal power plants and boiler houses operating on fuel oil. As a result of the analysis of the dynamics of pollutant emissions from stationary anthropogenic sources for the period 1997-2019 it has been established that the level of air pollution is assessed as low; there is a tendency towards a decrease in gross emissions from stationary sources. The main pollutants from thermal power plants are sulfur dioxide, nitrogen oxides, carbon monoxide, formaldehyde, and benzo(a)pyrene. Together with gaseous and liquid substances, fuel oil ash and products of incomplete underburning of fuel, which include heavy metals V, Ni, Cr, Pb, Fe, Sn, enter the atmospheric air. Technogenic compounds of heavy metals and other pollutants from the enterprises of the power unit, falling out with dust or precipitation on the surface and catchment areas of lakes, affect the formation of the chemical composition of surface soils, waters and bottom sediments of water bodies. This is reflected in an increase in the concentration of heavy metals (in particular, V and Ni) in the water and bottom sediments of the lakes of Murmansk in comparison with the background values.

According to numerous studies, even with a relatively low level of exposure to adverse environmental factors, risk of health deterioration may occur. Both the amount of harmful emissions and their chemical composition directly affect the level of air pollution. The article considers the issues of environmental pollution of an urbanized area by automobile exhausts. The most polluted city is Vladikavkaz that is the capital of the Republic. There the main stationary sources of pollution are located and the largest number of vehicles is concentrated. The dynamics of increasing the number of vehicles in the city of Vladikavkaz over the past 10 years and a corresponding increase in harmful emissions from combustion products are shown. For the same period of time, the amount of emissions of harmful substances into the atmosphere from stationary sources has been considered in order to compare their contribution to total pollution compared to road transport. Based on the explorations, it is shown that the main source of pollution in terms of emissions in the Republic of North Ossetia-Alania is road transport. The number of vehicles is increasing year after year, amid a decrease in total emissions of pollutants from stationary sources.

The article examines the state of air pollution in Temirtau, Karaganda region, and the dynamics of the air pollution index (API). The API is calculated based on the 5 main pollutants in the city, namely suspended particles, nitrogen dioxide, carbon monoxide, phenol and ammonia. The article describes the synoptic conditions of atmospheric air pollution in Temirtau, that is, the influence of baric structures, such as cyclones and anticyclones, troughs and ridges, on the maximum permissible concentration of harmful substances and their time in the city air. The meteorological quantity such as the wind contributing to the transport of pollutants is also considered, and a frequency diagram of the wind direction is presented in order to consider the transboundary transport of harmful substances from other regions. The materials of the article used maps of a certain period of time, such as baric topographic maps and terrestrial synoptic maps, and their analysis was carried out. Based on the results of the analysis of maps of a certain period, the article describes the conditions for the occurrence of synoptic processes favorable for the accumulation of large concentrations of harmful substances in the city. The topic under consideration will be interesting to specialists in the field of natural science, politicians and public figures who pay attention to the ecology of our country, in particular to the ecological system of cities with a large industrial complex, such as Temirtau, and to urgent global environmental problems affecting to the state of atmospheric air quality.


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.

In the urban environment, the main sources of pollutants entering the atmosphere are industrial enterprises and vehicles, which leads to a significant change in the composition of the air. Various monitoring methods are used to analyze the state of the atmospheric air. On their basis, methods have been developed to monitor the state of the natural environment of the technosphere. Most often, gas analyzers and various chemical methods for determining aerosol pollution are used. The creation of a methodology that makes it possible to quickly and efficiently assess the state of the environment is urgent. The described method of rapid assessment of the state of atmospheric air by bioindication and biotesting of dendroforms makes it possible not only to quickly and qualitatively assess the quality of atmospheric air, but also to take appropriate environmental measures in a timely manner. The developed rapid assessment includes several stages of the assessment of the objects under study, carried out depending on the goals of the study. To test the methodology, the objects of the study were the most anthropogenically loaded public green spaces (PGS) - public gardens of Sevastopol, located in different administrative districts of the city. The obtained results showed the possibility of using the developed methodology both in stages and in a complex manner.
