Abstract
Accumulation levels were determined for polycyclic aromatic hydrocarbons (PAHs) in naturally occurring objects over the territory of dispersing the emissions of the Irkutsk Aluminum Plant “IrkAZ–Sual”: in the snow cover, soil, pine needles (Pinus sylvestris L.) and larch needles (Larix sibirica), in water and the bottom sediments of the. Olkha River, as well as in the near-surface aerosols in Shelekhov City. An estimation was performed for the level of contamination with PAH compounds in the area of the Shelekhov City within the framework of the MPC and background levels, a conclusion has been drawn concerning the distribution of PAH emissions from the source over a limited area. Among the isolated fractions of PAHs, using a gas chromatography-mass spectrometry technique there have been identified and determined 14 arenes including those from the list of priority organic pollutants.
