Abstract
为了解淮河江苏段沉积物重金属的污染特征、空间分布及其生态风险,对其表层沉积物中重金属(Cd、Mn、Cu、Zn、As、Ni、Pb和Cr)的含量进行检测,利用相关性和主成分进行重金属来源分析,并采用富集系数与生物毒性不利影响对表层沉积物重金属进行污染评价.结果表明,除Cd与Cr外,Zn、Mn、As、Ni、Cu等重金属的含量均高于江苏土壤背景值.重金属含量空间分布差异明显,其中洪泽湖北部及围湖地区等地重金属污染状况最严重,来源可能来自城镇污水、工业废水等复合污染.富集水平排序为Zn>Mn>As>Ni>Cu>Pb>Cr>Cd,其中Mn、Zn富集程度最为明显.生物毒性不利影响评价总体处于中风险状态,主要贡献来源于Ni、Zn.除了 Cu、Cd、Pb外,Ni、Zn、Cr、As重金属可能会对底栖动物产生危害作用.因此,淮河江苏段沉积物重金属整体表现为较重生态风险水平.
