胶州湾海水、海洋生物体中重金属含量的研究

Heavy metals content in sea water and marine organisms at Jiaozhou Bay.

研究了胶州湾海水、海洋生物体中重金属含量 .结果表明 ,沿岸河口地区海水中重金属污染主要受沿岸工业排放废水的影响 ;海洋生物体内重金属含量不仅受海水中的重金属含量大小的支配 ,温度对其也有一定的影响 .海洋生物体中重金属含量为底栖生物大于鱼类 ,以沉积物为主要饵料的杂食性底栖动物内重金属含量大于鱼类 ;海洋生物对于Cu比其它重金属具有较强的富集能力 .

The results show that heavy metal pollution in sea water along the estuary of Jiaozhou Bay is mainly from the discharge of industrial wastewater nearby the estuary. The heavy metals content in marine organisms is affected not only by the content of heavy metals in sea water, but also by temperature. Benthons have a higher heavy metals content than fish, and marine organisms enriche more copper than other heavy metals.
