Abstract:

Snow samples are selected and the composition of PAHs in sediments of solid snow in the city of Bratsk is studied. A comparison with the industrial towns of Shelekhov, Novokuznetsk, and Syktyvkar. A close correlation between the quality (profile) of PAH in the snow cover near aluminum smelters, and emissions from sources of electrolytic shops of aluminium production technology with self-roasted anodes are found. The values of the relations of various PAHs in the gas and dust emissions from the electrolytic process of producing aluminum are found. The possibility of their use for identifying sources of pollution from aluminum plants is shown. It is found that the carcinogenic activity of PAH in the snow cover is formed mainly by the contribution of benzo(a)pyrene.

Keywords:

polycyclic aromatic hydrocarbons, snow cover, aluminum production
