A number of terrestrial plants are known not only to tolerate but also to hyperaccumu-late metals, and thus they might be useful for phytoextraction. Recently, a brake fern Pteris vitata) was identified that not only can tolerate up to 1500 mgkg arsenic in soil, but has also a bioconcentration factor of about 190 that leads to a content of 2.3% (dry weight), mainly as As " and As (Zhang et al. 2002).

Cleaning up arsenic-contaminated soil and water poses a significant problem. One approach is to find plants that will leach arsenic from the soil. Such a plant, the brake fern, recently has been shown to have a voracious appetite for...
