The aim of the study was to assess the carcinogenic risk to the health of the population of an industrialized city, caused by the probable presence of carcinogens in the ambient air. The results of laboratory control of the content of carcinogens in the atmospheric air of the city of Voronezh for 2017–2020 were used as the initial data. The carcinogenic risk was assessed in accordance with the provisions of Guideline R. 2.1.10.1920–04 «Guidelines for assessing the risk to public health when exposed to chemicals that pollute the environment.» Taking into account the regional peculiarities of the composition of pollutant emissions into the atmospheric air, 1,3-butadiene (source — production of synthetic rubber) should be classified as priority carcinogens requiring systematic monitoring and measures to reduce the volume of emissions and, accordingly, concentrations in the surface layer of atmospheric air and chromium 6+ compounds (the main source is an aircraft plant). These substances, depending on the territory (transport or industrial), contribute 69.9–75.7 % and 21.7–26.9 %, respectively, to the total values of the individual carcinogenic risk (from 4.27 × 10 –3 to 4.90 × 10 –3 for the adult population, from 3.38 × 10 –4 to 3.82 × 10 –4 for children 6 years old). For the rest of the laboratory controlled carcinogens (formaldehyde, lead, soot, styrene), the risks do not exceed the maximum permissible value. It was found that the territorial coverage of the urban area of Voronezh by monitoring the content of carcinogens in the atmospheric air (5 stationary and 5 route observation posts) and the number of laboratory-determined carcinogens (6 out of 18 taken into account in the projects of maximum permissible emissions of enterprises) is insufficient to obtain reliable information on the value carcinogenic risk to public health. To reduce the associated uncertainties in assessing the carcinogenic risk, further studies of the content of 8 carcinogens (1,3-butadiene, formaldehyde, lead, carbon black, chromium 6+, benzene, benz/a/pyrene, styrene) are planned at 13 additional control points of the urban area.

Introduction. The high level of environmental pollution in industrial cities, including carcinogens, causes an unacceptable risk to public health. In this regard, a quantitative risk assessment is required to develop preventive measures to reduce it. The aim of the study was to assess the carcinogenic risk to the health of the population of an industrialized city, caused by the probable presence of carcinogens in the ambient air, drinking water of the centralized water supply system, and the soil of the residential area. Material and research methods. The laboratory control of the content of carcinogens in environmental objects of the city of Voronezh for 2017-2020 was used as the reference data. The carcinogenic risk was assessed under the provisions of Guideline R. 2.1.10.1920-04 “Guidelines for assessing the risk to public health when exposed to chemicals that pollute the environment.” Results. Taking into account the regional peculiarities of the composition of pollutant emissions into the atmospheric air, 1,3-butadiene (source - production of synthetic rubber) should be classified as priority carcinogens requiring systematic monitoring and measures to reduce emissions and, accordingly, concentrations in the surface layer of atmospheric air and chromium6+ compounds (the main source is an aircraft plant), which contribute 69.9-75.7% and 21.7-26.9%, respectively, to the total values of the individual carcinogenic risk, which exceeds the maximum permissible level (1 • 10-4). The carcinogenic risk from exposure to drinking water pollutants (halogenated organic substances) and soil (under the scenario of accidental ingestion by preschool children) is below the maximum permissible risk (1 • 10-4). Conclusion. It is necessary to pay attention to increasing the sensitivity of the applied laboratory control methods, expanding the list of controlled carcinogenic pollutants, improving the monitoring system of carcinogens, and implementing measures to reduce the carcinogenic risk associated with atmospheric air pollution.

Introduction. The city of Norilsk is included in the list of cities participating in the federal project “Clean Air.” The comprehensive action plan for protecting atmospheric air of substances provides a 75% reduction in emissions and a decrease in the level of pollution from “very high” to “high.” The aim of the study was to assess human health risk from chemicals that pollute the atmospheric air of the city of Norilsk before the implementation of a complex of air protection measures. Also, we planned to identify priority factors and sources of risk. Material and methods. The assessment of carcinogenic, acute, and chronic non-carcinogenic health risks was carried out at 1105 points of location of residential buildings in the city based on summary calculations of dispersion. The database of parameters of 2145 sources of pollutant emissions into the atmospheric air of the city was used. Results. Unacceptable, including high levels of risk to the health of citizens, have been established to be registered throughout the city. More than 181.8 thousand people live in high-risk zones. Risks occur both during short-term and long-term exposure to atmospheric pollution. The risk indicators for respiratory disorders diseases of the immune system and the blood system are ten or more times higher than the acceptable levels. There have been eleven priority pollutants contributing up to 90% to unacceptable risks (nitrogen oxides, sulfur dioxide, copper, nickel, lead oxides, the sum of various types of industrial dust, etc.). Conclusion. In general, aerogenic health risks require urgent measures to reduce them. The planned measures to suppress sulfur dioxide emissions, nitrogen oxides, and dust in Norilsk are generally large-scale and adequate to the priority risk factors. At the same time, it is necessary to develop and implement measures to reduce emissions of heavy metal compounds. Until the levels of acceptable health risk are reached, measures of a medical and prophylactic nature are relevant as compensation measures provided for by current legislation.

The city of Zaporizhzhya is one of the most technologically advanced cities in Ukraine with significant scientific, technical and production potential. The city's industry is based on the metallurgical complex, which has a great influence on the state of the atmospheric air. This problem is of particular relevance in the Zavodskoy and Voznesenovsky districts of the city with a significant concentration of ferrous and non-ferrous metallurgy enterprises, which certainly emphasizes the relevance of solving issues of protecting the health of the population living in these areas. The article examines the assessment of the carcinogenic risk to the health of the population of the Zavodskoy and Voznesenovsky districts from the impact of formaldehyde emissions. The composition of emissions from stationary sources of industrial enterprises contains a variety of chemical compounds, of which the most common are suspended matter (aerosols, dust), carbon monoxide (II), nitrogen oxide (IV), formaldehyde and others. Their ingress into the human body leads to a deterioration in health, damage to organs and systems, the occurrence of chronic diseases. The results of calculations of the individual and population carcinogenic risk to the health of the population in Zavodskoy and Voznesenovsky districts under acute and chronic exposure indicate an average level of risk (10-4<ICR<10-3), that is, acceptable for professional groups and unacceptable for the general population, typical for most large industrial cities. The emergence of such a risk requires the development and implementation of planned health measures. Comparing the average individual carcinogenic and population levels of risk to public health in the two study areas with acute and chronic exposure, it can be noted that the level of carcinogenic risk in Voznesenovsky district is higher than in Zavodskoy.

Introduction. The city of Chita of Zabaikalsky region is one of the cities of Russia, priority on level of pollution of atmosphere. Of the order of 130 impurities emitted by the sources of the city, 12 are monitored at 5 posts of the Roshydromet network. Maximum monthly average concentrations are formed by benz (a) pyrene (up to 56.8 MPC), hydrogen sulfide (12.3 MPC), suspended particles (up to 4PDC), phenol (up to 3.6 MPC). Significant emissions (59.73 thousand tons in 2018) are aggravated by the use of coal as a fuel by heat and power enterprises and the private sector, climatic and geographical features. Within the framework of the Federal project “Clean Air” of the national project “Ecology”, it is envisaged to reduce the gross emission of pollutants into the atmosphere of Chita by 8.75 thousand tons by 2024, which should lead to a significant improvement in the safety and quality of life of citizens. It is necessary to identify the most “risky “components of pollution for health.It is important to understand: whether the environmental monitoring system reflects the real picture of the dangers posed by pollution of the city’s atmosphere; whether there is a need to optimize the monitoring system for the subsequent assessment of the effectiveness and efficiency of measures; what impurities and at what points should be monitored in the interests of the population, administration and economic entities implementing air protection measures.The aim of the study is to develop recommendations for optimizing the program of environmental monitoring of air quality in the city of Chita, taking into account the criteria of danger to public health for the subsequent evaluation of the effectiveness and effectiveness of the Federal project “Clean Air”.Materials and methods. Justification of optimization of monitoring programs was carried out through the calculation of hazard indices, considering: the mass of emissions and toxicological characteristics of each chemical; the population under the influence. A vector map of the city with a layer “population density” was used as a topographic base. The indices were calculated for regular grid cells covering the residential area. For each cell, the repeatability of winds of 8 points from the priority enterprises and the population within the calculated cell were taken into account. As a result, each calculation cell was characterized by a total coefficient, taking into account the danger of potential impacts of emissions. Based on the results of the assessments, recommendations were formulated to optimize the placement of posts in the city and the formation of monitoring programs.Results. Indices of carcinogenic danger to the health of the population of Chita ranged from 584,805. 96 to 0.03 (priorities: carbon (soot), benzene, benz (a) pyrene); indices of non-carcinogenic danger — from 1,443,558. 24 to 0.00 (priorities: sulfur dioxide, inorganic dust containing 70–20% SiO2, fuel oil ash). The greatest danger to public health stationary sources of emissions form in the North-Western, Western and South-Eastern parts of the city. Roshydromet posts in these zones are absent.Conclusions. As part of the objectives of the project “Clean Air”, it is recommended to Supplement the existing state network of observations of atmospheric air quality in Chita with two posts; to include manganese, xylene, vanadium pentoxide in the monitoring programs, to carry out the determination of Benz(a)pyrene et all posts, which will allow to fully and adequately assess the danger of emissions of economic entities, as well as the effectiveness and efficiency of the provided air protection measures.

Can Tho City is one the 5th largest city in Vietnam, with hight rate of economic growth and densely populated with 1,251,809 people, butsling traffic activities with 566,593 motobikes and 15,105 cars and hundreds of factories. The air in Can Tho city is polluted by dust and ozone. However, Can Tho city currently does not have a study on the simulation air pollution spread, therefore we do not have an overview on the status of air pollution in order to do not have solutions to limit the increase of pollution status of the city. The purpose of this study is to collect air pollutant emissions from other study. After that, TAPOM model is used to simulate the effects of ozone on the surrounding areas and study the ozone regime in Cantho city. The study results showed that the highest ozone concentration for an hour everage is 196 μg/m3. Compare with national technical regulation about ambient air QCVN 5:2013/BTNMT, ozone concentration is approximately at the allowable limit. The study of ozone regime had identified that VOC sensitive areas are Ninh Kieu district and a part in the south of Binh Thuy district, and NOx sensitive areas are the rested areas of Cantho city. The main cause contributing to increased VOC emission in the central area of the city is motorcycles, NOx emissions in the remaining areas of Cantho city are from the rice production factories. Proposals to protect the air quality in Cantho city are suggested.

There was executed the complex assessment of air pollution in the city Novokuibyshevsk in 2014. There were outlined basic chemicals exceeding hygienic standards, as well as causing both carcinogenic and non-carcinogenic health risk. Average concentrations of pollutants were shown to fail to exceed the average daily maximum permissible concentration, and on the basis of this air pollution index in the city of Novokuibyshevsk was the low in 2014. However, air pollution in the city of Novokuibyshevsk decreased not due to the reduction of the concentration of priority pollutants, but as a result of the revision of the admissible values for formaldehyde concentrations. Individual carcinogenic risks to the health of children under 18 years according to hexavalent chromium, benzene and formaldehyde exceeded the border of maximum permissible risk, and were attributed to the third reference range of risk values in accordance with the R 2.1.10.1920-04. The carcinogenic risk to the health of adults and the population of the city of Novokuibyshevsk as a whole was in the third reference range boundaries only for hexavalent chromium. However, the overall carcinogenic risk for health of children aged up to 18 years amounted to 1.18∙10-3 and moved into a fourth reference range boundaries. The total index of danger with all substances, the content of which was monitored in the ambient air in the city of Novokuibyshevsk, accounted for 17.74 and also demanded measures to reduce air pollution in the near future.

Introduction. Th e study of the infl uence of air pollution on the health of the population of industrial cities is an urgent task of preventive medicine.The purpose of the study— assessment of risk for population health of the city of Novokuznetsk, associated with the receipt in atmospheric air of polluting substances from SC «Kuznetsk TPP».Materials and methods.The paper presents the results of risk assessment for the health of the population of Novokuznetsk from the impact of atmospheric emissions of coal thermal power plant. Risks were calculated in accordance with the «Guidelines for the assessment of public health risks from exposure to chemicals that pollute the environment».Results.It was found that sulfur dioxide, coal ash, nitrogen dioxide had the largest share in the index of non-carcinogenic hazard of emissions. Th e maximum hazard index of carcinogenic substances was detected in hexavalent chromium. Th e greatest risk of immediate action, manifested in the development of refl ex reactions, was detected at two points of exposure to concentrations; it was determined by the infl uence of coal ash. In the formation of the risk of chronic intoxication, coal ash, sulfur dioxide, nitrogen dioxide, nitrogen oxide had the greatest impact; the greatest risk was detected at three points. Th e hazard coeffi  cients of the concentrations ranged from 2.04×10–4 to 6.723. The maximum index of danger equal to 29.31, corresponded to the residential district of Lenin square. Th e highest levels of carcinogenic risk identifi ed at three points were determined by exposure to hexavalent chromium.Conclusion.Th e work identifi ed environmentally disadvantaged neighborhoods of the city. It is shown that the main contribution to the formation of non-carcinogenic risk of health disorders of the city’s population is made by nitric oxide and nitrogen dioxide, coal ash, sulfur dioxide. Th e main carcinogen is hexavalent chromium. Th e total values of risks expressed in the multiplicities of excess of acceptable risk, for most points exceed 1, indicating a signifi cant impact of emissions on the health of the population. A set of atmospheric protection measures aimed at reducing risks to public health is recommended.

The air quality monitoring system in industrial cities is one of the systems for responding to risk factors in the public health system. The purpose of the study is, on the basis of a hygienic assessment of carcinogenic and non-carcinogenic risks from exposure to specific pollutants in the cities of Dnipro, Kamenskoye, Kryvyi Rih, to substantiate a program for regional monitoring of atmospheric air quality. Materials and methods. To achieve this goal, the results of air quality studies in the largest industrial cities of the Dnipropetrovsk region – Dnipro, Kryvyi Rih and Kamenskoe for the period 2005-2019 were analyzed in terms of phenol, formaldehyde, benzene, xylene and toluene, and carcinogenic and non-carcinogenic risks to public health were calculated in these cities. Results and discussion. According to the results of the study, individual carcinogenic risks in all three cities in terms of formaldehyde are medium, and in terms of benzene are high. The population carcinogenic risk ranges from 200-269 additional cases of cancer from exposure to formaldehyde and 3727-4426 additional cases of cancer from chronic inhalation exposure to benzene. The calculation of non-carcinogenic risks identified the priority specific air pollutants in the cities under study, as well as the main target organs. So the main systems that are influenced by the action of the studied chemicals are the central nervous system, the general development of the body and the blood system. Based on the risk assessment, it was established that it is necessary to include the Kamenskoye metro station for regional monitoring. It is necessary to include all pollutants from List A to the minimum list of investigated chemicals, and for the city of Dnipro and Kamenskoye it is additionally necessary to carry out studies of phenol, formaldehyde and toluene and in the city of Kryvyi Rih – formaldehyde and toluene. The mechanism of data processing and interaction between the subjects of monitoring has been substantiated for the timely identification of risks and the development of necessary preventive measures for risk management. Conclusion. It was found that carcinogenic and non-carcinogenic risks in industrial cities of the Dnipropetrovsk region are not acceptable. The existing monitoring system does not fully comply with the current requirements. The minimum program of the regional air quality monitoring system in the Dnipropetrovsk region has been scientifically substantiated

The paper presents the results of measurements of the content of benzo(a)pyrene (BaP) in the snow cover in the territory of the Ivanovo city. It was revealed that the concentration of BaP at the controlled points is 2.7 times higher than the background level on average. The degree of pollution of the snow cover in Ivanovo is much less than in Moscow (the level of excess varies in the range 2.3 - 89 times). The intake levels (from 0.02 μg/m2 to 3.76 μg/m2) and deposition density (0.02 - 1.88 ng/m2 · day-1) of BaP are estimated that are commensurate with the values typical for such areas, as urban areas of Germany and Canada. Interpolation the BaP concentrations in snow is allowed to reveal anomalies in the city with BaP content of 35 ng/l, which is 7 times higher than the average value for the whole city. The obtained data made it possible to estimate the BaP concentration in atmospheric air, which on the average is 0.7· 10-6 mg/m3, which is 0.7 fraction of the maximum permissible concentration. The values of individual carcinogenic risk for public health were calculated, which amounted to 0.6·10-6 and 1.6·10-6, which corresponds to negligible individual risk (for the adult population) or corresponds to the maximum allowable level (for children), respectively. The obtained results allowed to evaluate the environmental risk from pollution of the snow cover with BaP, the level of which corresponds to a moderate one, however, indicates a potential public health hazard related to the ability of the BаP to accumulate in environmental objects. It is established that the most likely source of BaP is automobile transport. The contribution of the fuel and energy complex should be much less.
