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. [ABSTRACT FROM AUTHOR]

Purpose – to study the territorial features of atmospheric air pollution of the regional administrative center without specific industrial sources of pollution, to determine carcinogenic and non-carcinogenic risks for the population. The study was carried out in Rivne. The results of our own observations, the materials of the State Institution “Rivne Regional Laboratory Center of the Ministry of Health of Ukraine”, the materials of the Central Geophysical Observatory of the Ministry of Emergency Situations in Ukraine were analyzed. It was found that in the atmospheric air of Rivne, a regional center with a number of industrial facilities of communal property and a developed road network, the presence of chemical compounds of different classes is stably recorded, the concentrations of which in 20-40% of the samples exceed the MPC and reference concentrations. Territorial indicators of the content of harmful substances are in the following relationship: motorway ≥ industrial zone > park zone. Hygienic assessment of air quality by MPC criteria allows it to be classified as slightly hazardous. According to the criteria of carcinogenic and non-carcinogenic risks, air pollution in the city is not safe for the population and requires the adoption of preventive measures. It was shown that with exposure of detected air pollution there is a rather high probability of damage to the respiratory system of the body and the appearance of congenital malformations, as well as the development of cancer pathology. Hazard assessment of air pollution by carcinogenic and non-carcinogenic risks indicators is more informative and critically significant for determining its effect on public health.
