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 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.

Экономическое развитие всех регионов основано на доступе людей к товарам и услугам, которые обеспечиваются современной транспортной инфраструктурой. Автомобильный транспорт является основным способом транспортировки грузов и населения. В то же время положительные аспекты использования транспорта тесно связаны с такими негативными аспектами, как загрязнение окружающей среды и отрицательным влиянием на здоровье человека. На территории Республики Северная Осетия - Алания наибольший вклад в загрязнение окружающей среды вносит деятельность предприятий цветной металлургии и автотранспорта. Более 30 предприятий находится в промышленном узле г. Владикавказа, и их деятельность в той или иной мере связана с загрязнением атмосферного воздуха. Значительный вклад в загрязнение воздуха вносит автотранспорт, количество которого в г. Владикавказе, по данным Федеральной службы государственной статистики, за последние 20 лет увеличилось более чем в 2 раза. Цель исследования. Изучение основных источников загрязнения окружающей среды автомобильным транспортом, исследование взаимосвязей между уровнем загрязнения среды, интенсивностью движения и экологическим классом автомобильного транспорта. Установление показателя загрязнения окружающей среды автомобильным транспортом, характеризующего степень воздействия на окружающую среду и здоровье населения. Методы исследования. В ходе настоящей работы были собраны и проанализированы все имеющиеся данные по динамике объемов выбросов от стационарных источников и автотранспорта на территории РСО-А за 1997–2015 гг. Указанные данные обрабатывались с помощью корреляционного и регрессионного анализов. Результаты работы. Результаты исследований позволили установить, что прослеживается прямая зависимость или тренд между плотностью потока машин и загрязнением воздушной среды. Установлено, что выбросы от автомобильного транспорта на порядок превосходят стационарные источники. Предложен суммарный показатель Zатм загрязнения атмосферного воздуха, рассчитываемый как сумма отношений концентрации отдельных загрязнителей к соответствующим значениям ПДК за вычетом количества используемых показателей. The economic development of any country is based on the access of population to goods and services that are provided by modern transport infrastructure. Currently, road transport is the most common way of transporting goods and people. At the same time, the positive aspects of using transport are closely related to such negative aspects as environmental pollution and negative impact on public health. On the territory of the Republic of North Ossetia-Alania, the largest contribution to environmental pollution is made by the activities of non-ferrous metallurgy enterprises and vehicles. More than 30 enterprises are located in the industrial hub of the city of Vladikavkaz, and their activities to one degree or another are associated with atmospheric air pollution. A significant contribution to air pollution is made by motor vehicles.Their number in Vladikavkaz has more than doubled over the past 20 years, according to the Federal State Statistics Service. Aim. Study of the main sources of pollution of an urbanized area by road transport. The research and identification of the relationship between the level of environmental pollution, traffic intensity and the ecological class of road transport and the establishment of an indicator of environmental pollution by road transport, characterizing the degree of impact on the environment and safety of the population. Methods. In the course of this study, all the available data on the dynamics of emissions from stationary sources and vehicles on the territory of North Ossetia-A for 1997–2015 were collected and analyzed. These data were processed using correlation and regression analyzes. Results.The research results made it possible to establish that there is a direct relationship or trend between the flow density of cars and air pollution. It was found that emissions from road transport exceed stationary sources by an order of magnitude. A total indicator Zatm of atmospheric air pollution is proposed, calculated as the sum of the ratios of the concentration of individual pollutants to the corresponding MPC values minus the number of indicators used.

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.

Abstract in this article, we look at the issue of air pollution in cities in the Asian part of Russia, which are the industrial centres of the regions. Air pollution is shaped by a number of factors, including natural ones. In recent years, studies have been carried out in Russia and in foreign countries to determine the impact of pollutants emitted into the atmospheric air. There is a direct correlation between the state of public health and the amount of pollutants in the atmospheric air. Exceeding the maximum allowable concentrations in the air of territories threatens the life and health of people living in them. We have looked at the level of air pollution in cities, including the most polluted ones, and the measures taken by the government and large companies to mitigate the negative effects.

The objective – to study the dynamic changes for the health risk of the population of the industrial center in accordance with the state of atmospheric air pollution with carcinogenic compounds. The assessment of the state of atmospheric air pollution was carried out by us based on the results of physicochemical analysis of samples taken in places attached to the locations of stationary posts of state monitoring. The concentration of identified substances was determined by conventional methods: spectral-luminescent and gas chromatographic. Heavy metal concentrations were determined using data from the Central Geophysical Observatory of the Ministry of Emergency Situations. The calculation of the inhalation load of chemical carcinogens and the risks associated with them (non-carcinogenic and carcinogenic) was carried out in accordance with domestic guidelines. The assessment of dynamic changes in the nature of atmospheric air pollution with a complex of carcinogenic substances was made 5 of them are constantly recorded at levels exceeding hygienic standards. When compared with the reference concentrations, all compounds are characterized by high coefficients, indicating the likelihood of their effect on the body's immune system, respiratory organs, malformations, etc. A high individual carcinogenic risk of the effect of chromium VI and nitrosamines was determined. A total carcinogenic risk is formed at levels of 2.5 – 3.9×10-3, which should be considered as high; this requires development and implementation of preventive measures. On the territory of the industrial center, a high level of air pollution with increased carcinogenic and non-carcinogenic risk is stably registered.

A feature of the tasks associated with the spread of harmful substances in the natural environment is the presence of a large number of parameters that affect the migration of im-purities. Mathematical models of varying complexity are used to describe such processes. The task of air monitoring by industrial enterprises is to collect, process the parameters of atmospheric pollution in the local area and develop, based on the results, conclusions regarding decision-making on the ecological state of both the industrial site and adjacent residential areas. An improved method of data approximation using piecewise polynomial regression is presented. The proposed algorithm makes it possible to increase the adequacy of determining the boundaries with a sharp change in the concentration of a harmful substance, improves the accuracy of the constructed models of the release of a substance into the atmospheric air and more accurately assess the scale of pollution. The developed methods allow visualization of the obtained data to increase the information content in assessing the pollution of a certain area.Along with mathematical models, when assessing the level of pollution, geographic in-formation systems (GIS) are used as a powerful tool that provides: collection, storage, pro-cessing, display of data, analysis, assessment, forecast of the state of the environment of a territorial community. The methods and algorithms described in the article form the basis of information technology and software for solving the scientific and technical problem of visual and analytical analysis of atmospheric air pollution data in the GIS «AirNorm». With the help of this GIS, the results of a computational experiment carried out on the indicators of the level of emission of NH3 for the source V-109 at the State Research and Production Enterprise (GNPP) «Zirkoniy» m. Kamenskoye were obtained and presented.
