Abstract
Concentrations of 23 polycyclic aromatic hydrocarbons (PAH) were determined in the bottom sediments of the tributaries: the Selenga, the Turka, the Khaym, the Barguzin, which provide more than 70 % of the water drainage into the Baikal, and in the bottom sediments of the shallow water regions of the lake: the Zmeevaya bay (Chivyrkuy arm) and the Sor-Cherkalovo bay. It was discovered that the level of pollution with PAH is relatively low; the sum of PAH concentrations for the 23 individual compounds is within the range 1.4-5.2 mg/kg (for 5 compounds, the range is 0.15-1.11 mg/kg). The presence of PAH in the samples of bottom sediments is due to local sources of petrogenic and pyrolytic nature.
