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.

• 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 .
