In order to ensure optimal operation of the existing environmental monitoring information system, it has become essential to use mathematical modeling based on the data assimilation algorithm. In this paper, a data assimilation algorithm has been designed and implemented. An algorithmic approach was tested for the assimilation of city atmosphere monitoring data from an industrial area. An industrial district of Karaganda city was selected for the investigation of the algorithm. The industrial district of Karaganda was taken as a research object due to the high level of atmospheric air pollution in industrial cities in the Republic of Kazakhstan. The result of our research and testing of the algorithm showed the effectiveness of the data assimilation algorithm for monitoring the atmosphere of the selected city. The practical value of the work lies on the fact that the presented results can be used to assess the state of atmospheric air in real time, to model the state of atmospheric air at each point of the city, and to determine the zone of increased environmental risk in an industrial city.

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.

Big cities in Śląskie Voivodship, especially those from the territory of the former Upper Silesian Industrial District, are characterised by a high level of industrialization, relatively high standard of living and very high level of environmental pollution. The aim of the study described in this paper is to assess the levels of selected types of air pollution in big cities in Śląskie Voivodship and to compare them against chosen reports on the health condition of the population of the voivodship in the years 2014–2016. The study was based on data from the Chief Inspectorate of Environmental Protection and Statistics Poland. The comparison of selected indicators of the health condition of the populations in the studied cities against their levels of air pollution demonstrated that in cities where air pollution reached the highest levels, the values of indicators of mortality were also the highest, whereas the values of indicators of life expectancy of newborn babies were the lowest. The worst situation regarding both the air pollution and health condition was observed in Chorzów, Dąbrowa Górnicza and Rybnik, and the best in Bielsko-Biała and Tychy.

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.

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 Russian Federation, one of the priority vectors of the development of the state is to improve the quality of justice, the guarantee of which is the effective judicial system. For the most optimal mode of functioning of the judicial system, an understanding of the main trends in its development is necessary, which requires a high level of generalization and scientific potentiation of the foundations of the organization and functioning of the judiciary, and is possible only if all previous stages of its development are analyzed. The main objective of the study: 1) determine the features of the development of the judicial policy of the Russian Empire in the regions, in particular in the Crimea; 2) to trace the evolution of the judicial system in the Crimea during its stay in the Russian Empire. When writing the work, methods of scientific research were used: dialectical, historical-legal, formal-legal, systemic, comparative-legal, historical periodization, diachronous, institutional-legal. The main results and conclusions of the study can be defined as: 1) judicial reform was a priority in the state legal policy of the Russian Empire at the end of the XVIII – early XX centuries; 2) the author's periodization of the reform of the judicial system in the Crimea. Such a consistent consideration of the organization and functioning of the judiciary allows for its comprehensive study as a historical phenomenon with its own genesis of organization and activity The article is of high scientific value, since it is the first generalizing study in the historical and legal literature devoted to the problems of the formation, development and modernization of the judiciary in Crimea as part of the Russian Empire (1783–1917), in which it was first used that were not previously included in the scientific circulation Sources of the State Archive of the Republic of Crimea of the Russian Federation.
