The metal contents in tissues of fish species: M. cephalus, Diapterus sp., Scomberomorus sierra and Oreochromis aureus, were determined in order to evaluate if their consumption might become a health risk. The liver and gills of M. cephalus and Diapterus sp. had the highest values of Cu, Fe and Pb. In the muscle, there were no interspecific differences in the Cd, Cu and Pb contents (0.27-0.32, 0.96-1.30 and 2.12-2.80 microg/g dw, respectively). Cd and Pb may be of concern, since their mean contents in the edible muscle of the four species are higher than the limits of the European Community.
为了评估食用这些鱼类是否存在健康风险，本研究测定了四种鱼类（蓝圆鲹、竹荚鱼、马鲛鱼和奥利亚罗非鱼）肌肉、肝脏和鳃中的金属含量。蓝圆鲹和竹荚鱼的肝脏和鳃中 Cu、Fe 和 Pb 含量最高。在肌肉中，Cd、Cu 和 Pb 的含量在不同种间没有差异（分别为 0.27-0.32、0.96-1.30 和 2.12-2.80μg/g dw）。Cd 和 Pb 可能存在问题，因为这四种鱼的可食用肌肉中的平均含量均高于欧盟的限量标准。
