| 摘 要： | 以云南蒙自大屯水稻田土壤为研究对象,利用BCR连续提取法分析水稻田土壤样品中Cu、Pb、Zn的赋存特征,这些赋存特征主要包括可交换及碳酸盐结合态、硫化物及有机物结合态和残渣态、Fe/Mn氧化物结合态和残渣态。研究表明应用BCR连续提取法能相对准确地了解该水稻田中重金属的污染情况及潜在释放能力。

| Abstract: | Taking soils in rice paddies in Datun, a township in Mengzi, Yunnan as a example, this paper analyzes the occurrence of heavy metals including Zn, Cu and Pb, using BCR sequential extraction. These metals are characterized with exchangeable ＆ carbonate bounded form, sulfide ＆ organic bounded form and residual form, Fe/Mn oxide bounded form and residual form. The research shows that the sequential extraction of BCR is helpful in understanding soil pollution and releasing capacity from heavy metals. |
