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.

<p>Soils of urbanized and mining areas succeeded the main geochemical features of parent materials, as well as accumulate potentially toxic elements (PTE) from different anthropogenic sources. The latter resulted in the change of soil chemical composition and high level of PTE which may have negative reflection on people’s health. In this study 207 soil samples were collected from the entire territory of the city of Alaverdi hosting Alaverdi copper smelter. After the determination of Fe, Ba, Mn, Co, V, Pb, Zn, Cu, Cr, As and Mo concentrations by XRF the established data set was subjected for the PTE induced health risk assessment. In this study two commonly used health risk assessment approaches - Summary pollution index (Zc) [1]–[3] and Hazard Index (HI, US EPA) [4] were used to assess human health risk posed by the content of studied PTE in soil of Alaverdi city. The result showed that the detected concentrations are mainly the result of superposition of PTE contents introduced into the environment from natural mineralization processes and Alaverdi copper smelter related activities. The health risk assessment showed that the Zc values belonging to the extremely hazardous level has point-like shape and are surrounded by the hazardous and moderately hazardous levels, respectively. Summary pollution index showed that approximately 53 % of the city territory including the residential part is under the risk suggesting the increase in the overall incidence of diseases among frequently ill individuals, functional disorders of the vascular system and children with chronic diseases [1]. The US EPA method were in line with the results of the Zc and indicated that the observed contents of elements are posing non-carcinogenic risk to adult mainly near the copper smelter. In the case of children single-element non-carcinogenic risk values greater than 1 were detected for As, Fe, Co, Cu, Mn, Pb and Mo in 122, 95, 86, 10, 10, 9 and 6 samples out of 207 soil samples and the mean HQ values decrease in the following order: As(2.41)>Fe(1.14)>Co(1.09)> Mn(0.61)>Pb(0.41)>Cu(0.32)>V(0.19)>Mo(0.11)>Cr(0.05)>Ba(0.03)>Zn(0.02). The multi-elemental non-carcinogenic risk observed in the entire territory of the city indicating an adverse health effect to children. The results of this study suggesting the need of immediate risk reduction measures with special attention to arsenic.</p><p><strong>References:</strong></p><p>[1]         E. K. Burenkov and E. P.

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 monitoring and the control of air pollution which is a consequence of the activities of district heating plants in the area of Nis have indicated that there is a cause and effect relationship between the emitted pollutants and air quality on one hand, and health risk on the other hand. The aim of this paper is to determine the correlation between district heating plants, air quality and health risk. The evidence of this connection is the hazardous health quotient and the level of total carcinogenic risk in comparison to measured immission concentration and expected immission concentrations of pollutants from district heating plants in the city.

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.

Background/Aim. Analysis of air quality in Serbia indicates that the city of Nis belongs to a group of cities characterized by the third category of air quality (excessive air pollution). The aim of the study was to analyze the degree of causality between ambient air quality affected by particulate matter of 10 ?m (PM10) and carbon monoxide (CO) and the incidence of respiratory diseases in preschool children in the city of Nis. Methods. We quantified the influence of higher PM10 concentrations and carbon monoxide comprising motor vehicle exhausts in the city of Nis on the occurrence of unwanted health effects in preschool children by means of the hazard quotient (HQ), individual health risk (Ri), and the probability of cancer (ICR). The methodology used was according to the US Environmental Protection Agency (EPA), and it included basic scientific statistical methods, compilation methods, and the relevant mathematical methods for assessing air pollution health risk, based on the use of attribute equations. Results. Measurement of ambient air pollutant concentrations in the analyzed territory for the entire monitoring duration revealed that PM10 concentrations were significantly above the allowed limits during 80% of the days. The maximum measured PM10 concentration was 191.6 ?g/m3, and carbon monoxide 5.415 mg/m3. The incidence of respiratory diseases in the experimental group, with a prominent impact of polluted air was 57.17%, whereas the incidence in the control group was considerably lower, 41.10 %. There were also significant differences in the distribution of certain respiratory diseases. Conclusion. In order to perform good causal analysis of air quality and health risk, it is very important to establish and develop a system for long-term monitoring, control, assessment, and prediction of air pollution. We identified the suspended PM10 and CO as ambient air pollutants causing negative health effects in the exposed preschool children population.

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.

Heavy metals are released into the water system through various natural processes and anthropogenic activities, thus indirectly or directly endangering human health. The distribution, source, water quality and health risk assessment of dissolved heavy metals (V, Mn, Fe, Co, Ni, Zn, As, Mo, Sb) in major rivers in Wuhan were analyzed by correlation analysis (CA), principal component analysis (PCA), heavy metal pollution index (HPI), hazard index (HI) and carcinogenic risk (CR). The results showed that the spatial variability of heavy metal contents was pronounced. PCA and CA results indicated that natural sources controlled Mn, Fe, Co, Ni and Mo, and industrial emissions were the dominant factor for V, Zn and Sb, while As was mainly from the mixed input of urban and agricultural activities. According to the heavy metal pollution index (HPI, ranging from 23.74 to 184.0) analysis, it should be noted that As and Sb contribute most of the HPI values. The health risk assessment using HI and CR showed that V and Sb might have a potential non-carcinogenic risk and As might have a potential carcinogenic risk to adults and children in the study area (CR value exceeded target risk 10−4). At the same time, it was worth noting that As might have a potential non-carcinogenic risk for children around QLR (HI value exceeded the threshold value 1). The secular variation of As and Sb should be monitor in high-risk areas. The results of this study can provide important data for improving water resources management efficiency and heavy metal pollution prevention in Wuhan.
