为研究土壤重金属的污染状况,从武汉市某工业用地土壤中采集26份样本检测分析了其Cu、Zn、Cr、Pb、Mn和Co元素含量.结果表明：土壤整体呈pH中性,土壤中的有机质含量偏低.表层（0～20cm）和次表层（20～50cm）土壤中重金属Cu、Zn、Cr、Pb、Mn、Co含量分别为27.08,198.68,67.95,18.72,525.50,69.44 mg/kg;和25.82,210.19,65.68,19.67,528.99,68.92 mg/kg.以湖北省土壤背景值为评价标准,该工业用地土壤重金属主要污染为Co,其次是Zn,该工业用地属于重金属重度污染.
為研究土壤重金屬的汙染狀況,從武漢市某工業用地土壤中採集26份樣本檢測分析瞭其Cu、Zn、Cr、Pb、Mn和Co元素含量.結果錶明：土壤整體呈pH中性,土壤中的有機質含量偏低.錶層（0～20cm）和次錶層（20～50cm）土壤中重金屬Cu、Zn、Cr、Pb、Mn、Co含量分彆為27.08,198.68,67.95,18.72,525.50,69.44 mg/kg;和25.82,210.19,65.68,19.67,528.99,68.92 mg/kg.以湖北省土壤揹景值為評價標準,該工業用地土壤重金屬主要汙染為Co,其次是Zn,該工業用地屬于重金屬重度汙染.

26 soil samples collected from an industrial land in Wuhan to study the pollutions of heavy metals.The contents of Cu,Zn,Cr,Pb,Mn and Co were analyzed.The results showed that the pH of the soil was neutral and the contents of organic matter were low.The concentrations of Cu,Zn,Cr,Pb,Mn and Co in surface soils(0~20cm) and subsurface soil(20~50cm) were 27.08,198.68,67.95,18.72,525.50,69.44 and 25.82,210.19,65.68,19.67,528.99,68.92 mg/kg respectively.Compared with soil background values of heavy metal in Hubei Province,the major heavy metal of soil pollution in the industrial land is Co,followed by Zn.This land was heavily polluted.
