Abstract

For a long period (2003 – 2015) the dynamics of pollution of the bottom sediments in the port water area is assessed for the main classes of pollutants: concentrations of chloroform-extractable substances (CES), petroleum hydrocarbons (PH) and heavy metals (HM). The investigated groups of substances are distributed unevenly along the bay: the increased content of both CES and PH is noted at the apex and central part of the water area, lowered ones – at the outlet. A reliable dependence of the PH concentration decrease in bottom sediments has been revealed since 2003, for CES such connection is absent. Pollution of marine soils by HM in the Streletskaya Bay has element character.
