This study was carried out to determine the concentration of metallic elements (Zn,<br />

Cu, Pb and Cd) in raw and cooked sample of Mercenaria mercenaria (hard clam) and<br />

during monsoon and non-monsoon season, samples collected along Setiu River,<br />

Terengganu. The metals concentration value decrease in the following order for both<br />

objectives: Zn > Cu > Pb > Cd. For January, Cu, Zn and Pb shows higher concentration<br />

in cooked sample while for Cd, the concentration is higher in raw samples. For July,<br />

only Zn and Pb shows higher concentration of metals in cooked samples and for Cd<br />

and Cu, higher concentration in raw samples. During monsoon and non-monsoon<br />

season, Zn and Pb shows higher concentration during non-monsoon season as<br />

compared to Cu and Cd which has higher concentration during monsoon season.<br />
