砷污染土壤的蜈蚣草修复研究进展

A Review of Researches on Pteris vittata Phytoremediation of Arsenic Polluted Soils

本文评述了As污染土壤的蜈蚣草植物修复及其对As的解毒机制的研究进展,内容着重包括蜈蚣草对As的富集特征,As在蜈蚣草中的赋存形态、迁移及其转化,土壤以及土壤中P、Ca和K等元素对蜈蚣草吸收、转运As的影响等方面。

A review was presented of researches on Pteris vittata, a hyper As accumulating plant, phytoremedying As-polluted soils and mechanism of its absorption and detoxification of arsenic in arsenic polluted soils, addressing issues such as accumulation, forms, transport and transformation of arsenic in the plant, and effects of soil properties and phosphorus, calcium and potassium in the soil on plant absorption and transport on As.
