对广东省海域24种代表性经济鱼类肌肉中的 Cu、Pb、Zn、Cd、Cr和 Ni 6种重金属的含量进行了测定,同时还测定了部分鱼样的内脏、鳃、骨、皮、鳞5种器官组织中的重金属。广东省海域经济鱼类的重金属含量,与国内外一些非污染海域或轻微污染海域经济鱼类的重金属含量相近,远低于“海洋生物污染评价标准”和“人体消费卫生标准”,这反映了栖息于广东省海域的经济鱼类受重金属污染的影响不明显,基本上处于良好状态。重金属在鱼体不同器官组织中的分布存在差异,肌肉中的重金属含量最低。
The contents of 6 heavy metals in Cu, Pb, Zn, Cd, Cr and Ni in 24 representative fish in Guangdong waters were measured. At the same time, the visceral, gill, bony, Scales of five kinds of organs and tissues of heavy metals. The contents of heavy metals in economic fish in the sea areas of Guangdong Province are similar to those of some non-polluted waters or slightly polluted waters in the world, far below the “Standards for Assessment of Marine Biofouling” and “Standards for Consumer Health”, which reflects The economic fish habitat in the waters of Guangdong Province are not significantly affected by heavy metal pollution and are basically in good condition. The distribution of heavy metals in different organ tissues of fish is different, and the content of heavy metals in muscle is the lowest.
