Rapid development occur in the both side of Johor Strait lead to the pollution issue,<br />

and rise an issue on the safety to consume the sea food the area. Since, the objective<br />

of this study was to determine the concentration of selected metallic elements (Cu,<br />

Zn, Cd and Pb) in the blue swimmer crab from the east of Johor Strait and estimate<br />

the potential health risk on human. The samples were digested with Teflon Bomb<br />

Digestion method and the concentration of selected metals in crab were detected by<br />

the Inductively Couple Plasma Mass Spectrometry (ICP-MS). Based on the analysis,<br />

the concentration pattern of metals in crabs decrease with Zn>Cu>Pb>Cd and the all<br />

metals concentration are much higher than the study in 1991. According to the<br />

recommendation of PTWI, the consumption of the crab from study area should not<br />

exceed 0.42 kg per week to avoid the adverse health impact.<br />
