| The concentrations of Zn, Cu, Pb and Cd in surface sediment, soft tissue and shell of oyster Saccostrea
cucullata collected from three locations, in the intertidal zones of Hormoz Island of the Persian Gulf were
measured. Concentrations of metals were determined by using Flame Atomic Absorption
Spectrophotometer (FAAS). Results indicated that the mean levels of metals in the soft tissue and the shell
were as Zn>Cu>Pb>Cd and Pb>Zn>Cu>Cd, respectively. Significant and positive correlations were found
between Pb (r = 0.97, P<0.05), Cd (r = 0.79, P<0.05), Zn (r = 0.99, P<0.01) and Cu (r = 0.77, P<0.05)
concentrations in the soft tissue of oyster and its concentration in the sediments. There was not a positive
correlation across Pb levels in the shell of oyster and sediment. The percent Coefficient of Variation (CV
%) for Pb within the shells were lower than for the soft tissues, whereas the CV% for Cu, Zn and Cd was
lower in the soft tissue than in the shell. The results of this study suggest that the shell of S. cucullata as
biomonitor for Pb and the soft tissue for Cu, Zn and Cd. |
