Studies on Heavy Metal Accumulations in Green-Lipped Mussel Perna viridis from Malaysia by Using Multiple Linear Stepwise Regression Analysis
The concentrations of Cd, Cu, Pb and Zn in soft tissue of green-lipped mussel Perna viridis from 15 sampling sites in Malaysia were found to be not serious but low when compared to regional data. However, samples from Kuala Perlis and Kg. Pasir Puteh should be given more attention since these loc...

| Summary: | The concentrations of Cd, Cu, Pb and Zn in soft tissue of green-lipped mussel
Perna viridis from 15 sampling sites in Malaysia were found to be not serious but
low when compared to regional data. However, samples from Kuala Perlis and
Kg. Pasir Puteh should be given more attention since these locations were
identified to have received anthropogenic metals. The multiple linear stepwise
regression analysis was found to be useful in finding the most influential
statistical parameters affecting heavy metal accumulation in P. viridis. The
regression analyses indicated that the parameters were rather constant regardless
of different sets of models being included in the procedure. Therefore, the
multiple linear stepwise regression analysis can be proposed as an alternative
statistical method for determining the most important variables affecting heavy
metal accumulations in P. viridis as well as in other invertebrates. |
