Abstract
In surface water and bottom sediments of the Gusinoye Lake (the Lake Baikal basin), there were concentration profiles determined for 19 polycyclic aromatic hydrocarbons (PAHs). It has been found that the total PAH content amounts to 7.1–33.7 ng/L for the surface water and 42.6–221.8 ng/g of dry solid matter for bottom sediments. It has been demonstrated that the presence of PAHs in the samples of surface water and bottom sediments of the Gusinoye Lake could mainly be caused by local sources having pyrolytic nature.
