| 摘 要： | 对焦作市南郊土壤重金属Pb、Zn、Ni、Cu、Co、Mn进行测定分析,并采用单因子与综合污染指数法进行了分析评价,根据土壤重金属含量特征,讨论了土壤重金属污染的原因。结果表明:研究区表层土壤中目标重金属大多处于背景值以下,或是轻度污染水平,其中Ni为主要污染因子,Pb为轻污染,Mn、Zn和Cu单因子指数值大多都在1左右,土壤仍处于尚清洁或警戒线等级,Co处于安全等级;综合污染指数大部分处于轻污染或以上等级。

| Abstract: | The contents of heavy metals in the southern suburb soil of Jiaozuo City,including Pb,Zn,Ni,Cu,Co and Mn,are determined.The corresponding data were assessed using the methods of single-factor pollution index as well as synthetic pollution index.Based on the characteristics of the contents of the soil heavy metals,the reasons for the heavy metal pollution of soil are analyzed and discussed.The results show that in the experimental area,the surface soil always contains a target heavy metal below the backgroun... |
