Assessment of selected heavy metals Perna viridis mussel and surface seawater in the coastal area of Pasir Gudang, Malaysia

Owing to its nutritional values, consumption of cultured marine bivalve such as P. viridis has gained popularity in many countries including Malaysia. Besides, the use of P. viridis as biomonitoring agent for heavy metal pollutions in coastal waters has also been suggested. The previous study on lev...
