| 摘 要： | 采用BCR(community bureau of reference)连续提取法对梅县玉水铜矿区周边农田土壤重金属Cu、Pb、Zn和Mn的形态分布及其生物有效性进行了分析.结果表明,矿区下游地区农田土壤重金属污染比上游严重,属于重污染区,而上游土壤属于轻度污染.矿区上游和下游农田土壤中,Pb的污染贡献最大.上游和下游土壤中Cu、Zn、Mn都主要分布在残渣态中,Pb主要分布在可还原态.上游和下游土壤中都以Pb的有效性最高,Zn的有效性最低.

| Abstract: | The three-step BCR(community bureau of reference) sequential extraction procedure method is used to analyse the speciation and bioavailability of heavy metals(Cu,Pb,Zn,Mn) in agricultural soils around copper mine tailing in Meizhou.Results show that downstream soil around mine is polluted heavily,which is polluted more seriously than upstream soil.Soil aronud mine is polluted by Pb mainly.In upstream and downstream soil around mine,Cu,Zn,Mn is dominantly released in the residual fraction.Pb is mainly releas... |
