Аннотация: The results of analysis of the content of benzo(a)pyrene and other high-molecular polycyclic aromatichydrocarbons (PAH) in atmospheric air samples collected in 2018 in industrial cities of the Krasnoyarsk region atthe state monitoring network of Roshydromet are presented. The PAH measurements were performed by the highperformanceliquid chromatography method, using a fl uorometric detector. The monthly average concentrations ofbenzo(a)pyrene in the atmospheric air exceeded 10 MPC in the cities of Minusinsk, Lesosibirsk, Krasnoyarsk, andAchinsk. The maximum monthly average content of benzo(a)pyrene during the observation period in 2018 wasfound in Minusinsk (January, 90 MPC) and Lesosibirsk (January, 59 MPC). The main reasons for the increasedlevels of air pollution with PAH are investigated. Seasonal variability in the content of benzo(a)pyrene and otherPAH in the atmospheric air of the Krasnoyarsk region cities with a maximum in winter and a minimum in summeris shown. The annual average concentration of benzo(a)pyrene in the atmospheric air in 2018 decreased in the followingseries: Minusinsk (17.2 ng/m3), Lesosibirsk (12.4 ng/m3), Krasnoyarsk (6.5 ng/m3), Achinsk (3.6 ng/m3),and Norilsk (0.6 ng/m3). A similar decreasing concentration trend in this series of cities is typical for other PAH.The level of air pollution with benzo(a)pyrene in the cities of Minusinsk, Lesosibirsk, Krasnoyarsk in 2018 ischaracterized as “very high.” The pyrogenic nature of PAH in the atmosphere of the surveyed cities of the Krasnoyarskregion is shown using molecular ratios.
