Justification of Risk-Oriented Assessment System for Assessing the Impact of Atmospheric Air Pollution on Population Health Based on Assessment of Benzene Level in Kamianske

Abstract

Air pollution in industrial cities is one of the sources of the formation of non-infectious diseases of the population. Timely identification and application of preventive measures makes it possible to control and reduce the incidence rate of the population of technogenically loaded settlements.
 Purpose of the study. on the basis of a hygienic assessment of the concentration of benzene in the atmospheric air of Kamianske, substantiate the need for a risk-oriented approach to assessing the impact of the environment on the health of the population.
 Materials and research methods. Based on the monitoring studies carried out for the period 2016-2020. carried out a hygienic assessment of the quality of atmospheric benzene content in. Kamenskoe. The calculation and assessment of carcinogenic risks and analysis of the current regulatory levels in Ukraine have been carried out.
 Results. According to the results of the research, the tendency to increase the content of benzene in the atmospheric air of Kamianske was revealed. In 2020, the MPC was exceeded. Carcinogenic risk (CR) in Kamianske is unacceptable and requires the development of measures to reduce or eliminate the risk. The population carcinogenic risk (PCR) for city residents is 906 additional cancer cases. The analysis of the obtained results showed that the analysis of air pollution in comparison with the maximum concentration limit, which for benzene is 1.5 mg / m3 for maximum single concentrations and 0.1 mg / m3 for average daily concentrations, does not allow to identify public health hazards in time. and develop the necessary set of preventive measures, in contrast to the risk assessment system.
 Conclusions. The tendency to increase the concentrations of benzene in the air in Kamyanske has been established. It is proved that the calculated carcinogenic risk is unacceptable for the population of an industrial city. The necessity of calculation and risk assessment for timely identification, risk assessment and development of preventive measures is substantiated. The use of risk assessment techniques allows to identify potentially dangerous effects for the population affected by the actual concentrations of benzene within the MPC.
