| 摘 要： | 对窟野河上游煤矿区和中下游非煤矿区的河流表层沉积物重金属As、Cu、Pb、Zn、Cd、Cr、Co和Mn含量污染特征进行了分析比较,并采用地积累指数法和潜在生态危害指数法评价其污染程度。结果表明:重金属含量均高于陕北地区土壤背景值,煤矿区和非煤矿区重金属含量有一定的差异性,其中Cr-Cu、Cr-Cd、Mn-Cu-Zn、Co-Pb、As-Cd和As-Pb元素间有一定的同源性。煤矿区和非煤矿区均受到不同程度的重金属污染,全水域处在强的潜在生态危害级别,Cd的影响占主导地位,后期应重点监控治理。

| Abstract: | Characteristics of heavy metals(As, Cu, Pb, Zn, Cd, Cr, Co, and Mn) contamination in surface sediment of Kuye River around coal mining area and non-coal mine area in Shaanxi Province, China were analyzed by using index of geo-accumulation and potential ecological risk index. Results indicate that all the contents of heavy metals in Kuye River are higher than soil background values of Northern Shaanxi Province. Contents of heavy metals in coal mining area and non-coal mine area have a certain difference. Relations of Cr-Cu, Cr-Cd, Mn-Cu-Zn, Co-Pb, As-Cd, and As-Pb show partial homology. Coal mining area and non-coal mine area suffer heavy metals contamination to a different extent and get a high level of potential ecological harm. Cd takes a great effect, and it should be monitored and governed in the future. |
