Bioaccumulation of Cd, Pb and Zn in the Oyster Saccostrea cucullata and Surface Sediments of Hendourabi Island-Persian Gulf, Iran
The concentrations of Cd, Pb and Zn in the shell and soft tissue of the oyster Saccostrea cucullata and surface sediment from the intertidal zones of Hendourabi Island, Persian Gulf, Iran, were studied. The aim of this study was to investigate the relation between concentrations of Cd, Pb and Zn in the shell and soft tissue of the oyster S. cucullata and the respective metal measured in surface sediment. The oyster and surface sediment samples were collected from three stations in June 2011. The mean concentrations of Cd, Pb and Zn in surface sediment were 2.36, 0.02, and 46.4 μg/g dw, respectively. In comparison with mean crust and mean world sediment, the Pb and Zn concentrations were far lower, while the Cd concentration was a lot higher than the mean crust Cd concentration.
