| 摘 要： | 采用模拟酸雨土柱淋洗实验，研究了不同土壤中酸可提取态重金属释放特征。结果表明，随着模拟酸雨pH值下降，土壤中酸可提取态重金属释放强度明显增大，各元素的释放量与酸雨pH值呈显著负相关。Zn释放主要集中在pH4.5~3.5之间；Cu释放主要集中在pH6.5~3.5之间；Cd的释放没有较集中的范围；而Cr和Pb，不同土壤集中释放的pH值范围不同。不同处理水平对酸可提取态种金属的释放有显著影响。

| Abstract: | A leaching experiment was adopted to study acid extracted heavy metals releasing in different soil. The result showed: With the pH dropping of simulated acid rain, the releasing intensity of acid extractable heavy metals obviously increase and the releasing amount of every heavy mental is negative correlation with pH. Zn is mainly released in pH 4.5~3.5; Cu is mainly released in pH 6.5~3.5, but the range of Cd is unsure; the releasing ranges of Cr and Pb are different in various soil. Moreover, the influence of acid extracted heavy metals releasing is obvious with different pH. |
