The seasonal distribution of heavy metals in Mussel sample from Yalova in the Marmara Sea, 2008-2009

Abstract

Concentration of the some heavy metals (Co, Cu, Fe, Ni, Pb and Zn) Mediterranean mussel Mytilus galloprovincialis from Yalova (Marmara Sea) were investigated seasonally. The mean concentrations of Co, Cu, Fe, Ni, Pb and Zn in the soft tissues were 4.08 +/- 0.67, 5.54 +/- 0.59, 156.72 +/- 20.18, 3.71 +/- 1.14, 2.92 +/- 0.51 and 106.23 +/- 5.66 mg kg (-aEuro parts per thousand 1) dry weights, respectively. There were no significant differences between the metal concentrations among the seasons (P > 0.05). The mean Pb and Zn concentrations were higher than the acceptable limit proposed by International Turkish standards.
