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.

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.

The objective – to study the dynamic changes for the health risk of the population of the industrial center in accordance with the state of atmospheric air pollution with carcinogenic compounds. The assessment of the state of atmospheric air pollution was carried out by us based on the results of physicochemical analysis of samples taken in places attached to the locations of stationary posts of state monitoring. The concentration of identified substances was determined by conventional methods: spectral-luminescent and gas chromatographic. Heavy metal concentrations were determined using data from the Central Geophysical Observatory of the Ministry of Emergency Situations. The calculation of the inhalation load of chemical carcinogens and the risks associated with them (non-carcinogenic and carcinogenic) was carried out in accordance with domestic guidelines. The assessment of dynamic changes in the nature of atmospheric air pollution with a complex of carcinogenic substances was made 5 of them are constantly recorded at levels exceeding hygienic standards. When compared with the reference concentrations, all compounds are characterized by high coefficients, indicating the likelihood of their effect on the body's immune system, respiratory organs, malformations, etc. A high individual carcinogenic risk of the effect of chromium VI and nitrosamines was determined. A total carcinogenic risk is formed at levels of 2.5 – 3.9×10-3, which should be considered as high; this requires development and implementation of preventive measures. On the territory of the industrial center, a high level of air pollution with increased carcinogenic and non-carcinogenic risk is stably registered.

The purpose of this article is to highlight and analysis of trends in total emissions of polluting substances in atmospheric air of Mogilev region. The main material. A brief overview of Belarusian scientistsʹ research in the fi eld of geoecological conditions of atmospheric air is given in the article. The article deals with pollutants accumulation in the air of Mogilev region from various sources. Mobile sources (64.1% in 2015) are mainly responsible for air pollution in the region. In 2015 in comparison with 2010 there was a decrease in pollutant emissions as a result of transport functioning. Sources of pollutants accumulating in the air are exhaust gases from internal combustion engines, crankcase gases and fuel evaporation from fuel systems. Automobiles dominate in the structure of vehicles (85.3% in 2015). The article considers dynamics of pollutant emissions from stationary sources. The majority of pollutants are found in the air because of technological processes. Hydrocarbons and sulfur dioxide prevail in the structure of emissions of these sources. Chemical industry enterprises (Mogilev chemical fiber, Mogilev artificial fiber plant, etc.) are the sources of air pollution. Substances of the 4th and 3d danger classes predominate in the structure of pollutants in Mogilev region. Substances of the 1st and 2nd danger classes are insignificant. Conclusions. As a result of the conducted research uneven territorial distribution of emission density of the main pollutants in the air of Mogilev region has been established. Kostiukovich and Krichevsk districts are characterized by high level of emission density of suspended substances, carbon monoxide, sulfur dioxide in the air from stationary sources. Cherikov district is characterized by a low level of carbon monoxide, sulfur dioxide, nitrogen oxide emissions per unit area. 71.4% of the administrative districts of Mogilev region are characterized by an average density level of carbon monoxide emissions from stationary sources in relation to the average regional level, 14.3% of districts by lower level, 4.8% by low level and 9.5% by high level. It is advisable to improve the production technology, to equip enterprises with new gas cleaning facilities in order to reduce the anthropogenic load on the environment.

The article deals with the dependence between atmospheric air pollution, resulted by the activity of fuel filling stations, and the morbidity of the population at the adjacent areas. The major human health consequences, arising from the inhalation of volatile components of commercial petroleum products, have been analyzed. It has been established that the content of petroleum products in the atmosphere in the zone of fuel filling stations influence exceeds the maximum permissible and corresponding background values. With the help of mathematical analysis it is determined that at these territories the risk for the population to get diseased with respiratory forms of allergy, asthma and chronic respiratory system disorders is higher, as compared with the territories outside the influence of fuel filling stations.
