We calculated the maximum and average annual concentrations of toxic substances from each emission source at each point of exposure to concentrations (PEC) of toxic substances associated with the microdistricts of residential area based on the distance between each PEC and each emission source, and the risks to the public health were calculated. Main results. Based on the results of the risk assessment, conclusions regarding the impact of the emissions of the enterprise of coal mining and enrichment on the health of the population of Novokuznetsk were drawn and their contribution to the reduction of the health level of the residents was assessed.
