• 摘要：牡蛎软体、贝壳和沉积物中Cd、Cr、Cu、Fe、Mn、Pb和Zn等重金属元素被同步分析研究。研究结果表明,重金属在牡蛎中的生物积累是牡蛎自身的新陈代谢、重金属元素的地球化学性质和环境诸因素综合影响的结果,其中牡蛎的生理作用对重金属在软体中的积累所产生的影响尤为重要,而贝壳中重金属的积累对来自环境的影响更为敏感。

• Abstract：Heavy metals including Cd,Cr,Cu,Fe,Mn,Pb and Zn in tissue and shell of oysters and sediments were synchro-studied. The results showed that the bioaccumulation of the heavy metals in oyster was synthetically affected by various factors such as the metabolism of oyster,geochemical behaviors of heavy metals and environmental conditions.

• Key words：heavy metal  bioaccumulation  oyster  influential factor
