The concentration of nine trace elements were analyzed in the different tissue organs of commonly available crabs (Portunus sanguinolentus, Portunus pelagicus and Scylla serrate) and bivalve (Polymesoda erosa) species collected from the Miri coast, Borneo in order to evaluate the potential health risk by consumption of these aquatic organisms. Among the analyzed organs, metal accumulation was higher in the gill tissues. The essential (Cu and Zn) and non-essential (Pb and Cd) elements showed the highest (i.e. Zn) and lowest concentrations (i.e. Cd) in their tissue organs, respectively. The estimated daily intake and hazard indices of all metals in the muscle indicate that the measured values were below the provisional tolerable daily intake suggested by the joint FAO/WHO Expert Committee on Food Additives. Compared to Malaysian and international seafood guideline values the results obtained from the present study are lower than the permissible limits and safe for consumption.
本研究分析了产自砂拉越美里海岸的常见蟹类（赤甲红蟹和远海梭子蟹）和双壳贝类（光滑河蓝蛤）的 9 种微量元素在不同组织器官中的浓度，以评估食用这些水生生物的潜在健康风险。在分析的器官中，金属在鳃组织中的积累量较高。必需元素（Cu 和 Zn）和非必需元素（Pb 和 Cd）在其组织器官中的含量分别最高（即 Zn）和最低（即 Cd）。肌肉中所有金属的估计日摄入量和危害指数表明，测量值低于粮农组织/世界卫生组织食品添加剂联合专家委员会建议的暂定每日耐受摄入量。与马来西亚和国际海鲜指导值相比，本研究的结果低于允许限量，可安全食用。
