TI  - Crystalline style and tissue redistribution in Perna viridis as indicators of Cu 
      and Pb bioavailabilities and contamination in coastal waters.
PG  - 413-23
AB  - The concentrations of Cu, Pb, and Zn in the crystalline style (CS) and in the 
      remaining soft tissues (ST) of the green-lipped mussel Perna viridis from 10 
      geographical sites along the coastal waters off peninsular Malaysia were 
      determined. The CS, compared with the remaining ST, accumulated higher levels of 
      Cu in both contaminated and uncontaminated samples, indicating that the style has 
      a higher affinity for the essential Cu to bind with metallothioneins. The similar 
      pattern of Cu accumulation in the different ST of mussels collected from clean 
      and Cu-contaminated sites indicated that the detoxification capacity of the 
      metallothioneins had not been overloaded. For Pb, higher levels of the metal in 
      the CS than in the remaining ST were found only in mussels collected from a 
      contaminated site at Kg. Pasir Puteh. This indicated a tissue redistribution of 
      Pb due to its binding to metallothioneins for Pb detoxification and the potential 
      of the CS as an indicator organ of Pb bioavailability and contamination. For Zn, 
      the above two phenomena were not found since no obvious patterns were observed 
      (lower levels of Zn in the CS than in the remaining ST) in contaminated and 
      uncontaminated samples due to the mechanism of partial regulation. Generally, all 
      the different STs studied (foot, mantle, gonad, CS, gill, muscle, and byssus) are 
      good biomonitoring tissues for Cu and Pb bioavailabilities and contamination. 
      Among these organs, the CS was found to be the best organ for biomonitoring Cu. 
      The present data also suggest the use of the tissue redistribution of Pb in P. 
      viridis as an indicator of Pb bioavailability and contamination in coastal 
      waters.
