Concentrations of Cd, Cu, Pb and Zn in Different Parts of the Byssus of Green-lipped Mussel Perna viridis (Linnaeus)

C.K. Yap, A. Ismail and S.G. Tan

Abstract:
The concentrations of Cu, Cd, Pb and Zn were analysed in different parts (root, byssus stem, byssal thread and attachment plaque) of the byssus of green-lipped mussel Perna viridis. Foot and total soft tissue were analysed for comparison. Heavy metal distributions in different byssus portions were observed. The attachment plaque recorded the highest levels of Cd (2.22 μg g-1), Cu (17.48 μg g-1), Pb (11.92 μg g-1) and Zn (73.94 μg g-1) when compared to the other parts of byssus, foot and total soft tissue. Different protein composition is believed to be the reason for the different heavy metal levels found in the different parts of the byssus.
