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ICPAES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 compared 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.
