The work presents the analysis of air pollution in the City of Odesa using, among others, the data of automated observations. The air basin state was also evaluated using individual parameters of sustainable development. According to the official data of the recent years the City of Odesa belongs to the most polluted cities of Ukraine in terms of air pollution. Based on the ranking results it was established that the level of atmospheric pollution in the City of Odesa can be classified as high for the most of pollutants. It is classified as acceptable for some substances (sulfur dioxide and nitrogen oxide) and as extremely high for formaldehyde concentration. After comparing the observational data related to content of individual pollutants at the OSENU's observation point and the data of long-term observations in the city it was found that the content of nitrogen dioxide generally corresponds to the average long-term values. The observations conducted at the points of the city network indicated that the content of carbon monoxide is two orders of magnitude lower and the content of PM10 is one order of magnitude lower than dust concentrations. The increased content of certain pollutants in the air (nitrogen dioxide, carbon monoxide, etc.) is observed in the summer-autumn period and caused by the traffic intensification. The evaluation of the city's air basin state using individual parameters of the environmental measurement index showed that we observed better conditions in 2014 and 2016. The conditions for sustainable development are characterized by average indicators, however, towards worsening of the situation. The results obtained in this paper form a basis for extending the implementation of the Resolution of the Cabinet of Ministers of Ukraine on introducing a new procedure for state monitoring of the atmospheric air in Ukraine. The existing laboratory base of the observation points requires radical re-equipment. It is also necessary to conduct an air pollution survey for identification of high priority pollutants and, based thereon, development of monitoring programs with consideration of the necessity for keeping certain impurities under control.

Introduction. High density of oil-producing and refining facilities in certain areas of Bashkortostan significantly affects the environment including ambient air quality in residential areas. Materials and methods. We analyzed concentrations of airborne toxicants (sulfur and nitrogen oxides, nitrogen and carbon oxides, hydrogen sulfide, ammonia, xylenes, toluene, phenol and total suspended particles) and population health status in the cities of Ufa, Sterlitamak, Salavat, Blagoveshchensk, and the Tuymazinsky District in 2007–2016. Pearson's correlation coefficients (r) were used to establish possible relationships between medico-demographic indicators and air pollution. Results. Republican fuel and energy enterprises contributed the most to local air pollution levels. Gross emissions from such enterprises as Bashneft-Ufaneftekhim and Bashneft-Navoil reached 43.69–49.77 thousand tons of pollutants per year. The levels of some air pollutants exceeded their maximum permissible concentrations. Elevated concentrations of ammonia, total suspended particles, nitrogen dioxide, and carbon monoxide were registered most frequently. High rates of congenital abnormalities, respiratory diseases in infants (aged 0-1), general mortality and morbidity of the population were observed in some oil-producing and refining areas. The correlation analysis proved the relationship between the concentration of carbon monoxide and general disease rates in adults based on hospital admissions (r = 0.898), general incidence rates in children (r = 0.957), and blood disease rates in infants (r = 0.821). Respiratory diseases in children correlated with nitrogen dioxide emission levels (r = 0.899). Conclusions. Further development of oil-producing, petrochemical and oil-refining industries should be carried out taking into account socio-economic living conditions of the population.

AbstractEvidences of an association between air pollution and Covid-19 infections are mixed and inconclusive. We conducted an ecological analysis at regional scale of long-term exposure to air-borne particle matter and spread of Covid-19 cases during the first wave of epidemics. Global air pollution and climate data were calculated from satellite earth observation data assimilated into numerical models at 10 km resolution. Main outcome was defined as the cumulative number of cases of Covid-19 in the 14 days following the date when > 10 cumulative cases were reported. Negative binomial mixed effect models were applied to estimate the associations between the outcome and long-term exposure to air pollution at the regional level (PM10, PM2.5), after adjusting for relevant regional and country level covariates and spatial correlation. In total we collected 237,749 Covid-19 cases from 730 regions, 63 countries and 5 continents at May 30, 2020. A 10 μg/m3 increase of pollution level was associated with 8.1% (95% CI 5.4%, 10.5%) and 11.5% (95% CI 7.8%, 14.9%) increases in the number of cases in a 14 days window, for PM2.5 and PM10 respectively. We found an association between Covid-19 cases and air pollution suggestive of a possible causal link among particulate matter levels and incidence of COVID-19.

In the article there were calculated near-surface concentrations of pollutants in the atmospheric air of Purovsk area, Jamal-Nenets Autonomous region. The purpose was to compare these with the maximum permissible concentration. The geo-ecological maps of dispersion of substances emissions into the air were made up using the unified program for calculating the air pollution taking into account the technical characteristics of sources and emissions themselves, natural, especially climate, conditions, as well as protection urban development activities and the lay of land. The conclusions were made about the excess in the atmosphere of maximum permissible concentration of solids on carbon monoxide in Purovsk, and on nitrogen dioxide in Purovsk, as well as in Ust-Purovsk Tazovskaya Guba permafrost areas.

The purpose of the work is to study the current level and the main trends of atmospheric air pollution of the cities of Ukraine with nitrogen dioxide to identify the most polluted cities, their ranking to determine the list of cities for the priority implementation of environmental measures. For the purpose of the study, the information of the Central Geophysical Observatory on the average annual concentrations of nitrogen dioxide in the air of 51 cities of Ukraine for the period 1998-2015 was used. The study used the classical methods of applied mathematical statistics (estimation of statistical parameters of distribution of concentrations, construction of time trends on the method of least squares, graphical methods of visualization of levels of air pollution), which were implemented using the available programs "MS-Excell" and "Statistica-8.0". The classification of cities according to the level of MPC exceeds average annual concentrations of nitrogen dioxide. 3 groups of cities were allocated: 1 group (21 cities) permissible level of pollution (<1 MPC); 2 group (27 cities) – increased level of pollution (1-2 MPC); group 3 (3 cities) – high level of pollution (2-3 MPC). It has been established that in the air of 21 cities (41% of all cities where nitrogen dioxide is monitored in the atmosphere) of 51 cities, there is an acceptable level of air pollution. In the remaining cities (59%) – there is a stable excess of MPC. In 23 cities, even the minimum concentrations of NO2 exceed the permissible standards. The study of long-term dynamics of nitrogen dioxide in air has shown that the increase of concentrations of this pollutant for 1998-2015 is observed in 28 cities (55%) of 51. The most significant increase in concentrations in the air occurred in Kherson, Lutsk, Donetsk and Gorishni Plavni. In 13 cities reduction of concentrations was recorded, and in 10 cities the content of this pollutant in the air practically does not change.

Using the 2008 Zaragoza International Exhibition “Water and sustainable development” as a case study, this paper aims to respond to the increasing demand for measurements of the effects and the implications of the performance of cross-sector partnerships from the perspective of their intended final beneficiaries. A contingency framework for measuring the short-, medium- and long-term effects of the 2008 Zaragoza International Exhibition is developed based on a “results chain” or “logic model”. Our results highlight that there are positive long-term synergies between the two main purposes of the 2008 Zaragoza International Exhibition; first, to increase public awareness of and commitment to the problems of water and sustainable development and, second, to make the city of Zaragoza better known internationally and to modernize its infrastructures. Although respondents to our survey consider that the long-term effects on the city are greater, the main short- and medium-term effects are related to awareness of water problems, sustainable development and non-governmental organizations. These results are in tune with what has happened around the city in the last 10 years providing indirect validity both to our study and to the proposed methodology.

The outbreak of COVID-19 has created a serious public health concern worldwide. Although, most of the regions around the globe have been affected by COVID-19 infections; some regions are more badly affected in terms of infections and fatality rates than others. The exact reasons for such variations are not clear yet. This review discussed the possible effects of air pollution on COVID-19 infections and mortality based on some recent evidence. The findings of most studies reviewed here demonstrate that both short-term and long-term exposure to air pollution especially PM2.5 and nitrogen dioxide (NO2) may contribute significantly to higher rates of COVID-19 infections and mortalities with a lesser extent also PM10. A significant correlation has been found between air pollution and COVID-19 infections and mortality in some countries in the world. The available data also indicate that exposure to air pollution may influence COVID-19 transmission. Moreover, exposure to air pollution may increase vulnerability and have harmful effects on the prognosis of patients affected by COVID-19 infections. Further research should be conducted considering some potential confounders such as age and pre-existing medical conditions along with exposure to NO2, PM2.5 and other air pollutants to confirm their detrimental effects on mortalities from COVID-19.

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.
