| 摘 要： | 研究了添加硫磺对Pb和Zn污染土壤的pH值、土壤中SO4^2-含量、土壤中Pb和Zn的NH4OAc浸提态含量及土壤中Pb和Zn的BCR(欧共体标准物资局)三步分级提取态含量的影响．结果表明：Pb和Zn污染土壤中添加硫磺后，土壤pH值降低，土壤中SO4^2-含量增加，土壤中Pb和Zn的NH4OAc浸提态含量随施硫水平的增加而增加；在对Pb和Zn的BCR三步分级提取态含量分析中，添加硫磺后，二者的B1态都有增加，Zn的B1态增加的比例要高于Pb，二者的B2和B3态都有不同程度的变化．

| Abstract: | A pot experiment was carried out with Pb/Zn contaminated soil by application of elements sulfur(S).Results indicated that soil pH decreased and the content of SO 2- 4 increased with application of S;the NH 4OAc extractable Pb/Zn increased with the application S increased.With the European Community Bureau of Reference(BCR)sequential extraction procedure,the content of B1 of Zn and Pb are all increased in the treatments with the application of S and the content of B1 of the Zn increased higher than that of Pb. |
