摘　　要：对分布于大连海区的5个调查位点的潮间带的表层污染物中重金属Cu、Cd和Pb的污染状况进行调查,分别采用单因子污染指数法和Hakanson潜在生态风险指数法对污染状况和潜在生态风险进行分析和评价。结果显示,大连海区潮间带的表层沉积物总体处于低污染水平和低潜在生态风险水平,仅个别位点样品的Cu达到中等污染水平。沉积物重金属污染水平与人类活动的影响程度有关。Heavy metals including copper,cadmium and lead in the sediments of intertidal zone in Dalian were studied.The single factor index method and potential ecological risk index method proposed by Hakanson had been applied to evaluate the harm of the heavy metals＇ pollution.The result showed that the comprehensive situation of the sediment quality was at a low level of pollution and potential ecological risk,but Cu in a specific site was at a medium level of pollution.The pollution level of heavy metals in sediments was related to human activities.
