Abstract

The content of hydrocarbons, including polyaromatic hydrocarbons and polychlorinated biрhenyls in the bottom sediments of the Nakhodka Bay was studied. It was shown that the content of the pollutants was similar to that of low polluted areas of the World Ocean. PAH and PCB concentration in the Nakhodka Bay did not exceed the toxic thresholds and did not pose any threat to the existence of aquatic organisms.
