A Comparison of Arsenic Speciation in 13 Pteris Vittata L.Populations
Synchrotron radiation X-ray absorption near edge structure was employed to study the arsenic (As) speciation in 13 Pteris vittata L.populations collected from 7 provinces,cities,and autonomous regions in China.As in roots of P.vittata was mainly combined with oxygen (O),with a small amount of As combined with glutathione (GSH).Populations from Hunan and Guangxi provinces showed higher percentages of As-GSH in soots.As in roots of P.vittata was predominated with As(Ⅴ),with the percentage of As(Ⅴ) to the total As being 59.6±0.6%~83.8±3.8%.The As(Ⅴ) percentage was in the order of HN5
