Abstract
Objective of the work:assessment and analysis of the risk to the health of the population of Novokuznetsk from the effects of atmospheric emissions from stationary sources of rail transport.Research methods:the volume of the maximum permissible emissions of the structural units of the OJSC “Russian Railways” in the city of Novokuznetsk was analyzed. The calculation of the maximum and average annual concentrations of toxic substances from each source for selected exposure points was made according to the “Methods for calculating the dispersion of emissions of harmful (polluting) substances into the atmospheric air” using the “ECO Center Standard” program. Health risks were calculated in accordance with the “Guidelines for the assessment of the public health risk when exposed to chemicals polluting the environment: “G 2.1.10.1920-04” and methodology A. P. Scherbo “Environment and health: approaches to risk assessment” were compared with acceptable values.Main results of the study:priority pollutants entering to the city’s atmosphere from stationary sources of OJSC “Russian Railways” and determining the risk of chronic intoxication are dioxide ferric, nitrogen dioxide, carbon oxide, hydrofluoride, sulfur dioxide. Soot as a carcinogen is not dangerous for public health. The highest total risk of chronic intoxication is observed in the area of the railway station. The greatest contribution to the formation of the risk of chronic intoxication is made by emissions from the sources of the wagon repair depot. The levels of immediate risks from exposure to all selected pollutants are zero. Determining of the levels of health risks taking into account the background concentrations of toxic substances revealed that the highest levels of immediate risks at all design points are observed from the influence of carbon oxide. The proposed activities aimed at reducing risk levels.Conclusion:stationary sources of the structural units of Russian Railways in Novokuznetsk contribute to air pollution in the city without having a significant impact on the health of the population.
