福建中、东部沿海主要养殖贝类体重金属的含量与评价

Contents and assessment on heavy metals in culture shellfishes from the middle and east of Fujian coastal areas

根据2000年11月福建中、东部沿海养殖贝类体重金属的检测资料,分析了牡蛎、菲律宾蛤仔、缢蛏体内重金属的含量水平。结果表明:闽江口附近海域和兴化湾湾顶北部海域养殖的褶牡蛎,体内Zn和Cd的含量明显高于其他养殖区。文中对3种养殖贝类的重金属污染程度进行评价的结果表明:闽中、东沿海的养殖贝类基本未受重金属污染或属微污染水平。

Based on the data of heavy metals in culture shellfishes from the middle and east of Fujian coastal waters in Nov. 2000, the contents of heavy metals in Ostred plicatuld, Ruditapes philippinarum and Sinonovacula coustricta were analyzed. The results could be summarized following:the content of Zn and Cd in oysters from the Minjian Estuary and north of Xinhua Bay head were much higher than those in other areas, respectively. In addition, the polluted level for the heavy metals in three culture shellfishes had been assessed. And it showed that most of the culture shellfishes from the middle and east of Fujian coastal waters were unpolluted or contaminated slightly by heavy metals.
