福建主要贝类养殖区表层沉积物重金属和有机质的含量及其相关性

Concentration of the heavy metals and organic matter in surface sedimentsfrom the main shellfish culture areas of Fujian and their correlativity

根据1998年4月对福清湾、湄洲湾北部、湄洲湾南部、旧镇湾等4个贝类养殖区的调查资料,分析了表层沉积物重金属、有机质的含量及其相关性。结果表明:表层沉积物的Cu、Pb、Cd、Zn和有机质含量除1个样品的Pb外,其余均符合一类海洋沉积物质量标准,质量状况良好。各重金属元素之间呈显著的正相关,与有机质也呈很好的正相关关系。

According to the data from the shellfishes areas of Fuqing Bay, the north of the Meizhou Bay, the south of the Meizhou Bay and (Jiuzhen) Bay in April 1998, the concentrations of the heavy metals and organic matter in the surface sediments and their correlativity were (studied). The result shown that the concentrations of Cu、Pb、Cd、Zn and organic matter conformed to the first-class standard of marine sediment quality except the Pb content in one sample, accorded with the national standard, and there were distinct positive correlations among the four (heavy) (metals),which also have the good positive correlations with the organic matter.
