Minor towns with population size of 50-100 thousand people are much rarely studied in regards of the ecological-hygienic assessment of human environment, in spite of the fact that they are characterized by specific ecological problems. The objective of the study was the hygienic assessment of the impact of urban environment on population health status in Tikhvin and Gatchina towns of the Leningrad region. Morbidity rate in the population of Tikhvin and Gatchina in 2005-2015, atmospheric emissions of industrial enterprises, findings on monitoring for both atmospheric air pollution and centralized drinking water supply, as well as motor transport noise levels were studied. Population health risk stipulated by industrial emissions and noise exposure was calculated. Statistical data treatment with correlation analysis of the relationship between environmental pollution indices and population morbidity was carried out. The study revealed increased atmospheric air pollutant concentrations in Gatchina, which might be connected with motor transport effect. Acute non-carcinogenic risk levels resulting from air pollutants are on the borderline of the admissible level, while in Tikhvin town those values are significantly lower. Estimated concentrations of atmospheric pollutants produced by industrial emissions are by 1.5-2 times lower than the actual levels shown by monitoring. Noise levels and predicted health risks in Gatchina are on the borderline of the admissible level, while in Tikhvin they are significantly reduced. The statistically significant gain in the general primary morbidity rate indices due to respiratory diseases in Gatchina town, correlated with atmospheric air pollution, was revealed. Our study showed that despite the presence of large industrial enterprises in studied towns, motor transport proved to be the key factor that forms air pollution and noise load, more typical of large cities.

Introduction. The object of the study is the results obtained during the implementation of the Federal Project (FP) “Clean Air” in 2020 in the supervised participating cities and the assessment of the possibility of implementing the tasks set for Rospotrebnadzor for effective health risk management, reducing morbidity and mortality of the population. The purpose of the study is to assess the risk to public health according to the summary calculations of atmospheric air pollution in the cities of Cherepovets, Lipetsk, Omsk, Novokuznetsk during the implementation of the FP “Clean Air” (baseline, 2017). Materials and methods. The primary approach to implementing the FP “Clean Air” in 2020 is to use the initial data (summary calculations of atmospheric air pollution) and obtain on their basis the levels of exposure and risks to public health. A software product of the “Ecolog-Gorod” series was used to calculate single and average annual concentrations. The health risk assessment procedure was carried out under the requirements of the manual R 2.1.10.1920-04. Results. Studies were conducted to assess the risk to public health based on the data of summary calculations of atmospheric air pollution in the cities participating in the FP “Clean Air” (Cherepovets, Lipetsk, Omsk, Novokuznetsk) in 2017 before the start of the measures provided for by the Comprehensive Plans to reduce emissions of pollutants into the atmospheric air. The assessment of the public health risk from atmospheric air pollution made it possible to establish: priority compounds contained in industrial emissions, the primary industrial sources and their share contribution, as well as the contribution of motor transport and independent heat supply sources emissions to the formation of pollution levels in cities; the population exposed to unacceptable risk levels were determined; substances that should be taken into account when quoting emissions were identified. The variants of improving the quality of preparation of the initial data of summary calculations for health risk assessment are recommended. Conclusion. There are suggested approaches to improving the quality of preparation of initial data of consolidated calculations for health risk assessment.

Fine Particulate

The paper deals with the quantification of fine particulate matter (PM10) dispersion in atmospheric air of an industrial city using the AERMOD model by an example of Zhlobin (the Gomel oblast, Belarus). Model input data and procedures for the emission inventory and obtaining spatially distributed estimates are described. Emissions and dispersion of PM10 from the main categories of sources are considered, including industrial facilities, road and off-road mobile sources, domestic sector, and agriculture. It is shown that the main contribution to high PM10 concentrations in atmospheric air is made by industrial enterprises, the domestic sector, and road transport. The spatial pattern of urban air pollution is described. The simulation results are compared with the results of PM10 measurements at the monitoring site, their satisfactory consistency is demonstrated.

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.
