中文摘要：

分析福建晋江感潮河段表层沉积物中重金属元素的质量比，采用单因子超标率法、地累积指数法和潜在生态危害指数法，对沉积物中重金属污染进行评价．结果表明，沉积物中重金属元素存在不同程度的污染，其中Cd呈极强污染水平，其次为Cu，而Zn，Pb，Cr，Ni呈中等或轻微污染．潜在生态危害指数表明，晋江感潮河段沉积物受重金属污染已相当严重，属于生态危害性极强的重污染水平，需采取有效措施加以治理．

英文摘要：

The concentrations of heavy metals in the surface sediments from tidal reach of Jinjiang River, Fujian Province, were analyzed. The pollution degree of heavy metals was assessed using the methods of Index of geoaccumulation and Potential ecological risk index. The results show that the pollution degree and the ecological risk of Cd appears the highest among all these heavy metals, and the secondary is Cu,Zn,Pb,Cr and Ni presenting moderate or slight pollution degree. The results of Potential ecological risk index indicate that the pollution degree of heavy metals in the surface sediments from tidal reach of Jinjiang River is much serious and belongs to the extremely strong ecological risk level. Some effective measures should be taken to prevent and control the heavy metals pollution.
