| 摘 要： | 采用Tessier A连续提取法,研究分析了沈阳市新城子铬渣堆存区土壤中重金属铬的污染分布和迁移转化规律,土壤中重金属铬的5种形态分布,主要以残渣态和碳酸盐结合态为主,分别占总量的49.74%和21.4%,而有机结合态含量最低,占总铬含量的6.25%。不同的功能区域铬的形态分布有所不同。总体的分布特征是残渣态>碳酸盐结合态>交换态>铁猛氧化态>有机态。

| Abstract: | By Tessier A sequential extraction method,we studied the relationship between heavy metal contamination and soil biological indicators of environmental quality in soils around a chrome coverage area in Xinchengzi county,Shenyang. The results show that Cr is mainly in residue and carbonate oxides fraction,accounting for 49.74% and 21.4% respectively. Cr in organic account for 6.25%. Different chrome states distributed in different area. The distribution character of chromium is remainder fraction > carbonate... |
