Aquatic organism and sediment absorb heavy metal from surrounding and accumulate in their body tissues and its surface area. The tissue of Marcia Marmorata sp. is being relatively eaten by the local people as other marine organism along the coastal area of Kuala Perlis. The tissue and sediment samples collected at four stations in Kuala Perlis Coast were analyzed for heavy metals by using an Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The bioaccumulation of metal in the soft tissue exhibit the following decreasing order: Zn > Cu >As > Cd while the mean concentration of heavy metal in sediment showed the following trend: Zn> Cu> Cd> As. The mean concentration of Arsenic (As), Cadmium (Cd) and Copper (Cu) in the tissue was exceeded the permissible limit except for Zinc (Zn) when compared to the FAO/WHO 2004 as well as Food Regulation 1985. Therefore it can be generalized that bivalve from the Coastal area of Kuala Perlis are not safe to consume in terms of these heavy metal concentration and constitute a risk for human health. Two-way ANOVA test indicated statistically significant differences (p<0.05) between sampling stations in the concentration of Zn while between the bivalve tissue and sediment indicated significance difference for As. Correlation coefficient were calculated to study the sediment and bivalve tissue relationship, which shows that there are no significance correlation among these metals, indicating that tissue of Marcia Marmorata sp. tend to regulate the levels of heavy metals in their tissue and may not reflect the levels in sediment to which there are exposed KeywordsBioaccumulation, Heavy metals, Bivalves, correlation coefficient, ICP-MS.
