Pteris Vittata L

The effects of arsenic uptake by Pteris vittata L. and Polystichum craspedosorum were examined. Pteris vittata L. were exposed hydroponically to 4Italic textItalic text.8 mg/L As(V) for 16 d and 4.05 mg/L As(V) for 24 h. Arsenic concentration in solution respectively decreased to 1.61 mg/L and 3.86mg/L. TF after 24 h was 0.81(1). Polystichum craspedosorum were exposed hydroponically to 3.26 mg/L As(V) for 20 days. As concentration decreased to 2.83mg/L after 16d and then increased slowly in the later four days. As contents in roots and fronds of Polystichum craspedosorum were 147 mg/kg and 90mg/kg. The results indicated that Polystichum craspedosorum was not good candidate for removal As(V) from water compared with Pteris vittata L..

Pteris Vittata L

This research was conducted to understand the characteristics of arsenic (As) accumulation in Pteris vittata L. for remediation the soil contaminated by highly toxic As-chemicals. After Pteris vittata L. grown in different test soil for 3 months in the greenhouse, the determination result shown that the hyperaccumulator not only could accumulate large amounts inorganic arsenic and little organic arsenic, but also the majority of As was found in the fronds (over 90% of total As-content in the whole plants, average value, mg) .Furthermore, if the plants grown for different time in the same As-concentrations soil, the maximum As-concentrations (mg/kg) of pinnas, rachis and fronds all came forth at the end of the second month, but the maximum total As-content of fronds at the third month, so we could enhance the effects of remediation by harvested the fronds for per 3 months. The As-concentrations and the average total As-content of per plant and the As removal rate of the rhizosphere also could demonstrate the conclusion by comparing the harvested the plants per 3 months or not in 6 months.
