The article presents the results of a risk assessment for the health of the Novokuznetsk residents from air emissions produced by the Kuznetsk plant of lightweight structures. The research has revealed substances that have the largest percentage in the total emissions of the enterprise. Among non-carcinogenic substances, the main pollutants included suspended substances, as well as dimethylbenzene (xylene), iron trioxide, white spirit and kerosene. The main carcinogenic substance contained in the emissions of the enterprise is chromium hexavalent. The highest indices of non-carcinogenic hazard were found in manganese and its compounds, dimethylbenzene and suspended solids. The maximum index of carcinogenic hazard is chromium. Indices of non-carcinogenic and carcinogenic hazards of pollutants have been determined. The risk of chronic intoxication and carcinogenic risk from points of exposure to concentrations is calculated. The total risks of chronic intoxication and carcinogenic risk were compared with acceptable levels in selected microdistricts of the city. It was revealed that the atmospheric emissions of the plant of lightweight structures do not have a signifi impact on the morbidity increase among the urban residents.
