摘　　要：通过对淮南矿区典型采煤沉陷水体(刘岗塘)中沉积物若干重金属元素含量的ICP-AES测定,分析了沉积物元素含量特征及变化趋势。对照Hakanson提出的工业化以前的重金属元素背景值,探讨了重金属元素的富集程度,运用潜在生态危害指数法评估了沉积物的污染程度。同时,根据周边直接及其他间接污染源特点,分析了其对沉积物重金属富集的影响。The concentration variation of heavy metals in sediments of a typical coal - mining induced subsidence surface water in Huainan mining area were investigated by inductively coupled plasma atomic emission spectroscopy（ICP-AES） . The concentrations of these elements were com- pared with their background values proposed by Hakanson before industrialization.The further assessment of heavy metal pollution was conducted on the basis Potential Ecological Risk Index （PERI） . Additionally, sediment quality for the metals could be adversely affected by direct and indirect pollution sources surrounding the subsidence water.
