Trace Metal Concentrations in the Greenlipped Mussel Perna viridis (Linnaeus, 1758) Collected from Maheshkhali Channel, Coxâ??s Bazar, Bangladesh
Aktar Mahbuba
The green-lipped mussel Perna viridis (L.) were collected from four sampling locations of the Maheshkhali channel, Cox’s Bazar, Bangladesh to determine the concentration level of zinc (Zn), copper (Cu), cadmium (Cd) and lead (Pb). The concentrations (μg/g dry weight) of these trace metals ranged from 28.12 to 33.82 for Zn, 7.26 to 8.81 for Cu, 0.04 to 0.08 for Cd and 0.19 to 0.75 for Pb. The concentrations of trace metals in the mussel tissue were found at lower level than the permissible limits for human consumption. In addition, these metal concentrati-ons are also considered to be low when compared with regional data using P. viridis as a bio-monitoring agent.
