Metal levels in biota from the Southern Black Sea, Turkey

Öz

Abstract In this study, toxic metal (Pb, Cd, Hg and As) bioaccumulations in mussel (Mytilus galloprovincialis), fish (Merlangius merlangus euxinus) and whelk (Rapana venosa) were researched along the Southern Black Sea Shelf in 2009. Generally, Pb and Cd contents were higher than the critical limits set by the Turkish Ministry of Environment for Aquatic Products (1 µg g-1 wet wt and 0.1 µg g-1 wet wt, respectively) and European countries (2.0 µg g-1, UNEP, 1985). They showed increases towards the eastern end of the shelf. As concentrations were also observed higher than the critical limits set by the Turkish Ministry of Environment for Aquatic Products (1.0 µg g-1 wet wt) at Terkos, Samsun and Ordu. In contrast, Hg levels were found lower than the critical limits set by the Turkish Ministry of Environment for Aquatic Products (0.5 µg g-1 wet wt) along the shelf.
