Verification of the establishment of the project borders of the seventh subzone of the near-airdrome territories by noise and carcinogenic factors

Introduction. Airfields and aerodrome territories are objects of hygienic and environmental expertise, since their functioning is accompanied by the impact of adverse factors on the population and the environment. In this regard, both at the design stage and during the operation of the airfield, a quantitative assessment of the risk to public health is necessary.

The aim of the study was to verify the establishment of the design boundaries of the seventh subzone of the aerodrome territory by noise and carcinogenic factors.

Materials and methods. The materials used in the work are design materials for the establishment of the aerodrome territory of the Voronezh civil aviation airfield ʺVoronezh (Chertovitskoye)ʺ and data from instrumental and laboratory control (noise factor, concentrations of carcinogens in atmospheric air) obtained by the Center for Hygiene and Epidemiology in the Voronezh Region.

Results. At the border of the seventh subzone of the aerodrome territory, the highest values of the estimated risk index for the noise factor were found to be characteristic of the risk for the cardiovascular system (up to 0.013), at the same time, they do not exceed the low risk level (less than 0.05). The levels of the total individual carcinogenic risk at the border of the seventh subzone of the aerodrome territory of the airfield are in the range from 3.01 · 10^–8 to 3.56 · 10^–7; outside the seventh subzone at the border of the nearest residential development in the range from 3.26 · 10^–8 to 2.16 · 10^–7, which is classified as the value of the target risk for the conditions of populated places in Russia.

Limitations. The limitations of the study are related to the fact that the work uses design data obtained using currently existing and approved calculation methods for noise levels and concentrations of carcinogenic substances in the surface layer of atmospheric air in the aerodrome area, as well as a limited number of results of instrumental measurements of noise levels and laboratory monitoring of carcinogens in the air. At the same time, the regulatory and methodological framework for assessing the risk to public health caused by the impact of the studied factors, taking into account the receipt of new data on the impact of adverse environmental factors on human health, is constantly being revised and improved.

Conclusion. The noise impact factor is decisive in establishing the boundaries of the seventh subzone of the aerodrome territory. The design boundaries of the seventh subzone of the aerodrome territory of the ʺVoronezh (Chertovitskoye)ʺ civil aviation airfield for the carcinogenic factor and the aviation noise factor are confirmed by full-scale laboratory studies of the concentrations of carcinogens in the surface layer of air and instrumental measurements of aircraft noise levels and comply with current sanitary and hygienic and environmental requirements.

Compliance with ethical standards. The study does not require the submission of a biomedical ethics committee opinion or other documents.
