摘要
对山东黑泥湾潮间带沉积物的重金属(Cu、Pb、Cd、Zn、Cr、As和Hg)和有机质进行了分析,并运用Hakanson潜在生态危害系数法对其潜在生态危害程度进行评估。结果表明:整个区域存在Pb污染,Cr和Cu污染见于黑泥湾南部;重金属潜在生态危害程度轻微;重金属污染来源主要受环境背景值、人为活动控制。
The heavy metals（Cu,Pb,Cd,Zn,Cr,As and Hg） and organ matters were measured in the intertidal sediments of Heini bay,Shangdong Province,and the potential ecological risk was evaluated by the ecological risk index suggested by Hkanson.The results showed that Pb contamination presented on the whole area,while Cr and Cu contamination only presented in the southern area.The potential ecological risk degrees were slight.The sources of heavy metal contamination were controlled by environmental background and man activities.
