By using P. viridis as a biomonitoring agent, the contamination of Cd, Cu, Pb and Zn in the west coast of Peninsular Malaysia was found not to be serious. Since P. viridis accumulates heavy metals in the soft tissues and constitutes one of the important food-chains in the coastal environment, this information is therefore useful for predicting any metal contamination in the coastal communities. The heavy metal concentrations in the mussels from the west coast of Peninsular Malaysia could be attributed to natural or anthropogenic metal sources affecting their habitats. The observation that the wild and aquacultured populations of P. viridis collected from the west coast of the peninsula were not seriously contaminated by Cd, Cu, Pb and Zn suggests that the mussels spend most of their time and obtain much of their food in non-contaminated areas of the coastal waters. Future studies should concentrate on the relative importance of water, sediment and food in the accumulation of metals by the mussels. From the human public health point of view, these results seem to show no possibility of acute toxicities of Cd, Cu, Pb and Zn if the edible mussels are consumed.
