Analysis of health risks of the population of the city of Obninsk from the eff ects of harmful substances emissions into the atmosphere

The article shows the results of the analysis of the environmental situation in the city of Obninsk, formed as a result of the current and previous activities of industrial enterprises, including the nuclear ones. In the course of the research, the data on federal, regional and object monitoring systems for emissions and the state of the natural environments in terms of their contamination with technogenic products with radiation and toxic effects on human health was collected, analyzed and systematized. Particular attention is paid to air pollution due to the significant contribution of the inhalation component to the entry of harmful substances into the human body. The content of pollutants in the air in the city was identified by monitoring results and the distribution calculation of surface concentrations. The quality of surface water and soil was also analyzed. A comparative assessment of radiation and chemical risks for the population of Obninsk was carried out. Based on the obtained values of potential risks, the leading factors in the formation of the technogenic burden on the population were identified. The conducted assessment and the analysis of risks of anthropogenic origin can be used in ranking the factors of possible impact on public health. Also, the results of environmental studies using math simulation can be useful for enhancement the existing monitoring system in order to ensure the environmental safety of the studied region.
