Abstract:

The possible levels of total concentration of the polycyclic aromatic hydrocarbons (PAH) and individual compounds of this class are determined for the first time in the atmosphere of Irkutsk as a typical industrial center in Baikal region. It is shown that in winter the PAH concentration can reach 300 ng/m³ (total amount of identified compounds), and the concentration of benzapilene (most dangerous carcinogen) can reach 30 ng/m³. Under certain meteorological conditions, the extremely high PAH concentration is observed in daytime. The summer PAH concentration does not exceed 1-6 ng/m³, and that of benzapilene is within 0.2-1 ng/m³ (within MPC) due to a wider self-clearing capabilities of the atmosphere. The PAH concentrations were determined by the method of microcolumn high-performance liquid chromatography with multiwave photometric detection.
