摘要
通过对大冶铜绿山铜铁矿尾矿库周围土壤中重金属形态分析实验 ,研究了重金属各种形态在土壤中的分布特征。由对比实验可知 ,尾矿库周围土壤中Cu、Pb、Zn、Cd等重金属含量都显著地高于对照样品 ,已经受到重金属的严重污染。土壤中重金属形态分布特征为 :w(Cr、Zn、Fe) :可交换态 <碳酸盐态 <有机态 <铁锰氧化态 <残渣态 ;w(Cu、Pb) :可交换态 <碳酸盐态 <有机态 <残渣态 <铁锰氧化态 ;w(Cd) :残渣态 ,有机态 ,碳酸盐态 <可交换态 <铁锰氧化态 ;w(Mn) :有机态 <残渣态 <可交换态 <铁锰氧化态 ,碳酸盐态。
Distribution characteristics of the heavy metal species in soils were studied by speciation analysis of heavy metals in the soils near Cu Fe tailings in Daye. The results show that the contents of Cu, Pb, Zn and Cd in soils near the tailing area are significantly higher than the normal values and have caused heavy pollution. The distribution characteristics of the heavy metal species in the soils are as follow: w (Cr,Zn,Fe): exchangeable species<carbonate species<organic matter species<Fe-Mn oxide species<mineral slag species w (Cu,Pb): exchangeable species<carbonate species<organic matter species<mineral slag species<Fe Mn oxide species w (Cd): mineral slag species, organic matter species, carbonate species< exchangeable species<Fe Mn oxide species w (Mn): organic matter species<mineral slag species< exchangeable species, Fe Mn oxide species, carbonate species
