EVALUATION OF ENVIRONMENTAL RISK FOR THE HEALTH OF THE POPULATION FROM THE EMISSIONS TO THE AIR OF THE PROCESSING ENTERPRISE
Abstract
Subject – emissions of the pollutants into the air by the enterprise Novokuznetskmramor, LLC. Objective – assessing the environmental risk to the health of the population due to the effects of atmospheric emissions from a marble processing enterprise. Methods. The enterprise emissions were estimated based on the analysis of the maximum permissible emissions volume. Hazard indices for acute and chronic exposure were calculated. The maximum and average annual concentrations of pollutants from each emission source at each of the points of exposure to concentrations (PEC) of the substances associated with residential districts based on data on the distance between each point and each emission source were determined. Health risks were calculated. Main results. The priority toxic substances contained in the atmospheric emissions of the marble processing enterprise were determined: diiron trioxide, manganese, hydrogen fluoride, nitric oxide, sulfur dioxide, carbon oxide, suspended substances, inorganic dust, and gasoline. Emission hazard indices were established with the determination of the specific gravity of each component of emissions into the air in hazard indices. Areas of the city, the most unfavorable for living, were identified. The risks to public health in Novokuznetsk related to the emissions into the air basin of a marble processing enterprise were determined. It was shown that the total risk of chronic intoxication was the highest for the residents of the Novobaydaevsky micro-district of the city (PEC N 3) – 1.25 × 10-4 and the Ordzhonikidze district (PEC N 2) – 9.31 × 10-5. At these points, the greatest carcinogenic risk to public health from exposure to gasoline was revealed. Conclusion. In general, emissions from the Novokuznetsk marble processing enterprise do not significantly affect the health of the population in the city.
