摘要
依据第二次海洋污染基线调查数据以确定渤海沿岸站位底栖贝类体内重金属和有机污染物含量范围和分布特征。结果表明,沿岸贝类体内Cd的含量普遍较高,而As、Hg和Pb的浓度水平大多较低。辽东湾沿岸贝类体内检测到较高的DDT显示附近区域有新的DDT输入。PCBs的生物残留量以莱州湾近岸为最高,其次是渤海湾近岸;酞酸酯的生物残留主要出现在莱州湾和辽东湾沿岸站位。渤海沿岸大部分站位贝类体内DDTs组份含量已超出相应的USEPA人体健康和野生动物的质量基准,应予以关注。
Based on the second survey on marine pollution baselines,the concentrations ranged and distribution characteristics of the heavy metals and different organic pollutants in benthic mussels from the Bohai Sea coast were determined.The results showed that,the residual concentrations of Cd in the mussels were usually high,while the concentrations of As,Hg and Pb were low in most coastal sites.The high contents of DDTs detected in the benthic mussels showed the new inputs nearby.The highest concentrations of PCB...
