| 英文摘要 | The objective of this study was to explore potential plant candidates to act as phytoremediators around the Xikuangshan mine, Hunan Province, China. Native plants including Imperata cylindrical (L), Rumex patientia L., Fagopyrum dibotrys (D.Don), Fagopyrum dibotrys (D.Don), Phytolacca americana L., Dryopteris erytbrosora, Pteriduum aquilinum var. latiusculum (Desv), Nephrolepiscordifolia (L) Presl, Oplismenus undulatifolius (A) Bea, Erigeron annuus (L) Pers, and soils samples were collected. As, Sb, Hg, Cd, Cr, Pb, and Zn levels were measured in soil and plant samples. The concentrations of As, Sb, Hg, and Cd in soils were above the corresponding background values for Hunan province. R. Patienti, P. aquilinum, and P. americana had large bioconcentration factors (BAFs) and high translocation factors (TFs) for Sb; and the same showed in D. erytbrosora for Hg, P. vittata for Cd, I. cylindrical for Cr, and D. erytbrosora for Pb and Zn. In general, perennial plants showed high heavy metal contents in roots, and TFs greater than 1 were only observed for Sb in E. annuus and Cr in O. undulatifolius. These results demonstrate that several native plants growing around Xikuangshan are potential phytoremediators for metal and metalloid contaminated soils. |
