В статье исследовано состояние загрязнения атмосферы и заболеваемости населения на территории г. Владикавказа за пятилетний период. Установлена тенденция к снижению выбросов в окружающую сре- ду главным образом за счет уменьшения объемов производств и выполнения природоохранных меропри- ятий на промышленных предприятиях города. Вместе с тем, отмечается рост количества автотранспорта и его техногенная нагрузка на среду неуклонно увеличивается. State of air pollution and the incidence of population on the territory of Vladikavkaz city for the five-year period are investigated in the paper. The tendency of reduction of emissions into the environment (mainly due to the reduction of production volume and implementation of environmental activities at the industrial enterprises of the city) is stated. At the same time, number of vehicles and corresponding anthropogenic impact on the environment are steadily increasing

At present much attention is paid to the investigation of the indicative features of organisms on the whole and vegetative objects in particular. However, it should be noted that sources of toxic elements distributed unevenly on the territories and having various character and intensity in the form of the enterprises and constructions create rather motley picture of environmental pollution both by structure of pollutants, and by their concentration. Therefore an important scientific problem is the examination not only of changes in conditions of technogenic influence in general, but the research of dependence of intensity of morphological plants parameters change on structure and concentration of chemical pollutants in the environment, and also the assessment of possible consequences of pollutants accumulation in vegetative objects. This was the aim of this work. To perform the work used landscape-geochemical analysis include, extending the definition of the emission factor load, characteristic technogene sources of pollution in the form of industrial plants, evaluation of storage medium (vegetation). Vegetation condition was assessed by determining morphological parameters - the length and width of the leaf blade. The article presents a comparative assessment of the anthropogenic impact level of the largest industrial enterprises on the air state in the city of Gomel. Enterprises of western and southern industrial zone have proved to make the greatest contribution to the urban air pollution. The value of the standard deviation was used to assess the degree of anthropogenic impact of industrial enterprises on morphological parameters of woody plants. This index increased in the western and southern industrial zones in the direction from the enterprises with the large volume of pollutant emissions to the enterprises with the small volume of emissions. This trend is caused by stabilizing selection action due to the environmental stress in the form of emissions of the industrial enterprises in these zones. It is also revealed that in western and southern industrial zones the formation of the leaf blade length and width depends more on the level of anthropogenic impact of the chemical plant, combined heat and power plant, JSC «Centrolit» and JSC «Gomeldrev» compared with other companies, that should be considered when further improvement of environmental activities. The results are generally characterized by scientific novelty of the research and can be used for the purpose of indexing the level of anthropogenic impact on urban areas and further improve the methods of monitoring the state of the urban environment. Next it is planned to evaluate the morphological parameters of the leaf blade of woody plants growing in the area of two large industrial enterprises of the Gomel region – JSC «Mozyr Oil Refinery» (Mozyr), JSC «Belarusian Metallurgical Plant» (Zhlobin) and in city parklands. Then the further testing of the heavy metals content will be carried out in the samples of woody plants, grasses and soil from the territory of the industrial enterprises and parklands of the city of Gomel, Mozyr, and Zhlobin.

Atmospheric pollution arising from diesel-powered engines can result in acute and chronic diseases of the respiratory and cardiovascular systems. The annual carnival festival that takes place in the city of Salvador, Bahia-Brazil, is a large-scale event that gathers approximately 2 m revelers and 170,000 workers who accompany dozens of sound-trucks, or trios elétricos, for a period of seven days. These slow-moving sound-trucks run on diesel fuel, constantly exposing those around them to exhaust fumes. The present study aimed to evaluate air quality along the approximately 10km-long carnival parade circuit and determine possible impacts on human health. We applied a three-phase risk analysis strategy from 2007–2009: 1) hazard identification, 2) risk characterization and 3) risk management. Our quantification of atmospheric particulate matter 2.5 (PM2.5) and nitrogen dioxide (NO2) concentrations revealed variable levels of PM2.5 ranging from 19 µg/m3 to 580 µg/m3, with peaks of up to 800 μg/m3 at sound-truck concentration areas. We then assessed the effects of air pollution on human health using ophthalmologic parameters obtained from 28 carnival volunteers, who often presented symptoms of eye irritation. Finally, we established strategies to communicate the study’s objectives and obtained results to the population through media outlets and open discussions with government agencies. According to our risk analysis, carnival sound-trucks represent the main source of atmospheric PM2.5 and NO2 pollution during the annual 7-day carnival festival. As a consequence of our research, the municipal government of Salvador issued an addendum to its carnival legislation mandating organizers to monitor atmospheric pollution, and, subsequently, all large-scale public events. Municipal government authorities have also promoted a shift from petroleum-based diesel fuel to biodiesel, a less-polluting fuel, for all adapted carnival sound-trucks. Our approach, which employed easily accessible and inexpensive methodology, provided substantial scientific evidence to support improvements in the regulation of air quality during large-scale public events held in the city of Salvador.Keywords: environmental

The combination of factors that determine the level of atmospheric pollution, the priority harmful component of which is dispersed particles, has a random and unique character for the urbanized territory of «InnoKam». Therefore, to study the process of atmospheric pollution of this urbanized territory, an approach was used that takes into account that the content in the air of dispersed particles of motor transport and industrial origin depends on the nature of the processes of upsurge, propagation and deposition, which are determined by the fractional composition of particles, structural and functional parameters of road traffic flows., climatic and urban features of the territory and meteorological conditions. The aim of the study is to reveal the patterns of air pollution in the urbanized territory of «InnoKam» with dispersed particles, which is relevant and necessary for the effective implementation of measures to create a favorable and comfortable urban environment, as well as the attractiveness of the innovation and production center for visiting specialists and investors. Regularities of air pollution in the urbanized territory of «InnoKam» by dispersed particles, which is formed when pollution from road traffic flows are superimposed on the polluting background of industrial enterprises, have been investigated. Motor transport streams are both independent sources of the formation of dispersed particles, and a source of upsurge and spread of dispersed particles over considerable distances beyond the boundaries of highways. To reveal the regularities and obtain the corresponding mathematical models, both instrumental methods based on measuring the content of dispersed particles DCh 10 and DCh 2.5 in the atmosphere of the investigated urbanized territory, and statistical analysis of experimental data were used. Mathematical models have been obtained that, with a high degree of reliability, describe the regularities of air pollution by dispersed particles for the urbanized territory of «InnoKam», which is the scientific value of the results obtained. The practical significance of the results obtained lies in their use for predicting and compiling air pollution maps with dispersed particles in all parts of the urbanized territory of «InnoKam» in order to develop and substantiate measures to create a favorable and comfortable urban environment. The main activities are analyzed and divided into three groups, based on the specifics of the sources of formation of dispersed particles (vehicles, traffic flows, highways). The ranking of measures for the effectiveness of reducing air pollution by dispersed particles is the object of further research.

Introduction. The issue of air pollution is relevant in cities where the majority of the population lives and a large number of industrial enterprises are concentrated in relatively small areas. Currently, the federal project “Clean Air” is being implemented in 12 industrial centres of Russia within the framework of the national project “Ecology”. The purpose of the work was to justify using statistical and mathematical methods for assessing the impact of atmospheric pollution on the health of the population in the city of Novokuznetsk, Kemerovo region. Materials and methods. The following methods were used: assessment and management of public health risk, statistical analysis methods: factor analysis, multiple regression analysis, discriminant analysis. Results. Statistical indices and public health risk parameters can be used to assess the impact. Examples of the effect of complex pollution indices (the main components of pollution, the integral indicator P) and the concentrations of individual impurities in the air basin (suspended substances, ozone) were given. The carcinogenic risk to the population of Novokuznetsk, calculated from the calculated concentrations of atmospheric pollutants, was found to exceed the acceptable risk threshold. The specific weight of carcinogens in the formation of the risk to other oncological incidence was determined. An assessment of the risk from the emissions of a coal-processing plant located near residential areas of the city was carried out. The values of the hazard indices showed an excess of the acceptable non-carcinogenic risk only from the emissions of the coal processing plant, taking into account the background level of air pollution in the air basin. Conclusion. In Novokuznetsk, it is proposed to use the method of ranking atmospheric protection measures in terms of the unit cost of risk reduction in health risk management. To manage the risk, it is proposed to calculate the population indices of aerogenic hazard or the probabilistic parameters of the individual threat associated with air pollution. It is noted that a 20-22% reduction in pollutant emissions for Novokuznetsk may not be enough. The reasonable measures for the further study of the aerogenic impact on the population of the city are presented.

One of the regions of Ukraine, which is subject to significant man-made impacts on the atmospheric air, is the city of Zaporizhzhya. The paper presents the results of assessing the quality of atmospheric air based on the calculation of the air pollution index and the integrated air pollution index of the city of Zaporizhzhya. For the assessment, the data of long-term observations at the stationary posts of the city for 2016—2020 were used for the main pollutants. A list of the main pollutants (formaldehyde, dust, carbon monoxide, phenol, nitrogen oxides, sulfur dioxide) and the contribution of each of them to the general level of atmospheric pollution has been determined. The calculations of air pollution indices were carried out for the average daily concentrations of substances for each observation post in Zaporizhzhya for the study period 2016—2020. The calculation of the air pollution indices for the posts was carried out for all concentrations of the investigated substances, except for hydrogen sulfide due to the lack of data for it. The highest values of the indices are observed in 2017 and 2019, the lowest — in 2020. Over the past year, there has been a tendency towards a slight decrease in the level of air pollution by pollutants. The highest values of indices exceeding 1 are noted for substances such as dust, nitrogen dioxide, nitrogen oxide, phenol and formaldehyde. Calculations of the integrated index of atmospheric pollution at posts showed their heterogeneity, the list of measured substances is not unified for all posts. Formaldehyde, nitrogen oxides, phenol and dust make the largest contribution to the formation of the integrated air pollution index. Environmental monitoring in the city of Zaporizhzhya does not include measurements of hazardous toxicants, the presence of which is typical for large cities. The highest level of the integrated air pollution index is observed at the posts located in the zone of influence of the main industrial site, and reaches values of 5,4—9,8, which corresponds to a high level. In other areas of the city, where there is industrial potential, observations are not carried out; it is impossible to assess the level of air quality according to the data of the hydrometeorological service.

Common Understanding

Analysis of air pollution by pollutants, sources of pollution, types of economic activity, and administrative areas in the city of Novokuznetsk over 5 years was carried out. The largest share in the city air emissions is accounted for: CO – 61.8 %; SO2 – 17.4 %; solids – 11.3 %; NO2 – 5.9 %; CH4 – 1.8 %. Dynamics of gross emissions by years is shown. Planned implementation of the approved measures of the national project Ecology will make it possible to reduce air pollution in the city by more than 20 % by 2024, which corresponds to the federal project Clean Air. According to planes of the city industrial enterprises, environmental programs have been prepared, with monitoring by environmental specialists from the city administration and public control. Various measures were taken: automatic stationary posts were put into operation to monitor air pollution in real time; mobile laboratory was acquired to measure urban air. To improve waste management in the city, separate collection projects were implemented. Environmental assets exist and develop in the city, which ideas and projects find common understanding and form ecological attitude of the urban community. Trends in gross emissions of pollutants into the atmosphere of Novokuznetsk are shown for the period of 2014 – 2018; refinements and explanations of the observed trends are given.
