ASSESSMENT OF THE RISK TO THE HEALTH OF THE POPULATION FROM ATMOSPHERIC AIR POLLUTION DURING OPEN-PIT MINING OF NON-ORE MINERAL MINERALS

A study was conducted to assess the risks to public health from atmospheric air pollution during open-pit mining of non-metallic minerals, and it was proposed to consider methods for assessing the impact of pollutants on public health. Risk calculations are offered non-carcinogenic and carcinogenic effects using the proposed methods. The risk of the development of non-carcinogenic effects is determined by calculating the hazard index (HI) and is compared with the criteria for assessing the non-carcinogenic risk. The hazard coefficients of pollutants were calculated according to the formula and the hazard indices of non-carcinogenic effects were determined with the combined effect (summation) of these pollutants on the health of the population. It was established that the hazard index HI = ΣHQi both overall and for groups of critical organs and systems does not exceed 1. Si concentrations (estimated average annual concentration of i-th substance at the boundary of residential buildings, mg/m3) do not exceed the MPC, less than one. Hazard ratio НQ < 1 (the risk of harmful effects is considered negligible) for all substances. The risk of the development of individual carcinogenic effects (ІСRі) from substances that have a carcinogenic effect was calculated, as well as the carcinogenic risk under the combined effect of several carcinogenic substances polluting the atmosphere (СRа) was calculated and compared with the classification of levels of carcinogenic risk. It has been established that the carcinogenic risk of benzo(a)pyrene during open pit mining corresponds to an acceptable level of risk. According to our calculations, it has been established that the risks of impact on the health of the population during open mining of non-metallic minerals will be insignificant.
