Depuration of trace metals in transplanted perna viridis from polluted site at Kg Pasir Puteh to relatively unpolluted sites at Kg Sg Melayu and Sg Belungkor in the straits of Johore
In this study, the green-lipped mussels Perna viridis were transplanted from a relatively unpolluted site at Kg. Sg Melayu (KSM) to a known polluted site at Kg Pasir Puteh (KPP) and an unpolluted site at Sg. Belungkor (SB). Total soft tissues of mussels were determined for Ag, As, Be, Co, Cr, Cs, Hg...

| Summary: | In this study, the green-lipped mussels Perna viridis were transplanted from a relatively unpolluted site at Kg. Sg Melayu (KSM) to a known polluted site at Kg Pasir Puteh (KPP) and an unpolluted site at Sg. Belungkor (SB). Total soft tissues of mussels were determined for Ag, As, Be, Co, Cr, Cs, Hg, Li, Mn, Se, Sr and V by using an Inductively Coupled Plasma-mass Spectrometer. After transplantation periods (2 and 6 weeks) to KPP, concentrations of As, Co, Cr, Hg, Li, Be, V, Cs, Mn and Sr increased but the concentrations of Ag and Se decreased after transplantation of 2 and 6 weeks. This indicated that KPP is almost confirmed as having the highest bioavailabilities of the above 10 metals than KSM and SB. However, the higher levels of Ag and Se found in the transplanted mussels at KSM should be investigated in future studies. After transplantation periods (2 and 6 weeks) to SB, concentrations of Co, Cr, Hg, Be, V, Cs, Se, Mn and Sr decreased but the concentrations of Ag and Li increased after transplantation of 2 and 6 weeks. This verified that SB is suitable coastal water for depuration of Co, Cr, Hg, Be, V, Cs, Se, Mn and Sr. However, higher levels of Ag and Li at SB than KSM could be attributed to unknown pollution source in the surrounding area which should merit further studies. |
