| 摘 要： | 目的]评估珠三角地区电镀厂土壤重金属的生物有效性及风险情况。方法]采集珠三角地区不同电镀厂的土壤样品,采用BCR提取法测定土壤样品中Pb、Zn、Cu、Cr、Ni等重金属元素4种形态的含量,评估珠三角地区电镀厂重金属的浸出风险。结果]珠三角地区电镀厂土壤污染的主要重金属类型为Cr、Zn、Cu,Pb和Ni的污染较小。珠三角地区电镀厂土壤中Zn、Cu、Cr的风险非常高,土壤条件若有改变就会带来重金属的浸出。场地1土壤样品中Zn、Cu、Cr严重超标;场地2土壤样品中Cu和Cr严重超标;场地4土壤样品中Zn严重超标;场地5土壤样品中Zn、Cu、Cr属于重污染;场地6土壤样品中Zn、Cu、Cr、Ni严重超标。结论]该研究可为珠三角地区重金属污染治理提供依据。

| Abstract: | Objective] To evaluate the bioavailability and risk of heavy metals in soil of electroplating factory in the Pearl River Delta.Meth-od] The soil samples were collected from different electroplating factories in the Pearl River Delta.The contents of Pb,Zn,Cu,Cr,Ni and other metal metals in four forms in soil samples were determined by using BCR extraction method .And the leaching risk of heavy metals in electropla-ting factory in the Pearl River Delta was assessed.Result] Main heavy metals in polluted soil in electroplating factory in the Pearl River Delta were Cr,Zn,Cu,but the pollution of Pb and Ni was lower.The risks of Zn, Cu,Cr in soil of electroplating factory in the Pearl River Delta were very high.If the soil conditions were changed,heavy metals would be leached.The contents of Zn,Cu,Cr in soil samples from plot 1 exceeded the standard limits greatly;The contents of Cu and Cr in soil from plot 2 exceeded the standard limits greatly;Zn content in soil samples from plot4 exceeded the standard limits greatly;The pollution of Zn,Cu,Cr in soil samples from plot 5 were serious; The contents of Zn,Cu,Cr,Ni in soil samples from plot 6 exceeded the standard limits greatly.Conclusion] The research can provide basis for the treatment of heavy metals pollution in Pearl River Delta regions. |
