摘 要: | 为了解滏阳河邯郸段沉积物中重金属含量以及各污染物的生态风险程度,通过采集19个监测断面的表层沉积物,利用电感耦合等离子体质谱仪分析6种重金属元素,以当地土壤环境背景值做参比并采用地累积指数法对沉积物中重金属的污染进行综合性的评价分析。结果表明:滏阳河邯郸段表层沉积物已经不同程度受到Zn、Cu、As、Cd、Pb污染,各种重金属的污染程度为:Cd(强)Zn(中)Cu(无-中)As(无-中)Pb(无),总体呈低度污染水平。

Abstract: | In order to know the heavy metals content and the degree of the potential ecological risk in the sediments of Fuyang River in Han- dan, by collecting surface sediments of 19 monitoring sections, using ICP-MS to analyze six kinds of heavy metals, with environmental back- ground values in the local soil as control and using the index of geoaccumulation, pollution of heavy metals in sediment was evaluated and ana- lyzed. The results showed that : the sediments of Fuyang River in Handan have been varying degrees of Zn, Cu, As, Cd, Pb pollution, pollu- tion of heavy metals: Cd (strong) 〉 Zn (in) 〉 Cu (no-in ) 〉 As (no-in) 〉 Pb (no) , the overall level of contamination was low. |
