| 摘 要： | 我们的研究首次发现一种耐寒的、适应性强的、速生的欧洲蕨，能在短时间内将土壤中有大量砷吸收并积累到其复叶之中，它不仅能祛除土壤中不同浓度的砷，还能祛除土壤中不同形态的砷，且欧洲蕨体内高达93％的砷被富集到复叶，从而使欧洲蕨成为修复土壤砷污染的救星。

| Abstract: | A versatile, fast-growing brake fern(Pteris vittata) can take up large amount of arsenic into its fronds in a short time. As well as removing arsenic from soils containing different con- centrations of arsenie, brake fern also removed arsenic from soils containing different arsenic species, and up to 93% of the arsenic was concentrated in the fronds. And so we recommend brake fern for use in remediation of arsenic-contaminated soils. |
