Eugene Ng, Y. J., Yap, C. K., Zakaria, M. P. and Tan, S. G. the parts had decreased. The high CF values in the metals (Table 6) showed that P. viridis was capable of accumulating these metals. In particular, TST was highly capable of accumulating Cd and Cu while the byssus was capable of accumulating Pb and Zn and the shell accumulated the highest Ni concentration. The total soft tissues of P. viridis showed the highest CF values for most of the metals, and this indicated that it is useful for monitoring metal contamination in coastal waters. The results obtained in the present study are also comparable to those of Yap et al. (2003a, 2004) which showed that P. viridis is a good accumulator for Cd, Pb and Zn. This test revealed the ability of P. viridis to accumulate and eliminate metals in short periods of time. Among the CF values for week 6 and week 10, Zn was the one which was accumulated the fastest while Cd was the slowest. Metal Elimination in Mussels Fig.2 to 7 show that all the metal concentrations in the mussels transplanted from Kg. Pasir Puteh to Sg. Melayu had decreased starting from T 0 to T 10. The Cd level decreased from 6.55 to 2.3 µg/g, Cu from 37.81 to 2.84 µg/g, Fe from 2909.69 to 14.98 µg/g, Ni from 55.06 to 13.64, Pb from 46.43 to 16.01 µg/g and Zn from 176.24 to 7.05 µg/g. Similar findings were also reported by Gabr and Gab-Alla (2008) for clams (Ruditapes decussatus and Venerupis pullastra) transplanted from a polluted site to a clean site. As for the mussels transplanted from Kg. Pasir Puteh to Sg. Melayu, there was no significant difference (one-way ANOVA, SNK, p< 0.05) observed for all the tissues in the Cd concentrations for T 0, starting from T 2, however, the shell was found to be significantly different from the total soft tissue and byssus. As for Cu, the total soft tissue and byssus were significantly different from the shell from T 0 to T 10. On the other hand, the total soft tissue and byssus were significantly different from the shell for the Fe concentration from T 0 to T 10. The rate of elimination (Table 7) for all the metals in the different parts of the transplanted mussels from Kg. Pasir Puteh to Sg. Melayu was the fastest in all the mussel parts in week 2 (T=2) and this became slower in the subsequent weeks until week 10 (T=10). For byssus, the rate of elimination was 0.23(T=2), 0.084 (T=6) and 0.033 (T=10) in Cd. During the first 6 weeks of transplantation, the elimination factor (EF) in byssus was the fastest for Cd (0.42) and Ni (0.49). Meanwhile, the EF in shell was the fastest in Cu (0.22) and Pb (0.35) and slowest in Cd (0.80). The EF in TST was the fastest for Cu (0.69), Fe (0.65), Pb (0.72) and Zn (0.74). During the 10-week transplantation, the elimination factor (EF) in byssus was the fastest for Cd (0.38), Ni (0.25) and Zn (0.37). Meanwhile, the EF in shell was fastest for Cu (0.19), Fe (0.42) and Pb (0.34) and the slowest for Cd (0.80). These results indicated that byssus eliminated Cd, Ni concentrations the fastest while shell eliminated Cu and Pb the fastest. At week 6, the concentrations of Cd in TST, Cu in byssus and TST, Ni in byssus and shell, Fe in byssus and TST, Pb in byssus and TST and Zn in byssus and TST were far from reaching the concentrations measured in the initial population (T 0). At week 10, only Cu, Fe, Pb and Zn in byssus and Ni in shell were far from reaching the concentrations measured in the initial population (T 0). Such findings had also been reported by several authors when organisms from polluted areas were transplanted to clean areas such as Zn in the mussel M. edulis (Roseijadi et al., 1984; Simpson, 1979), Cd and Cu in the oyster Crassostrea gigas (Geffard et al., 2002), Cr, 86 Pertanika J.
