  • Title: Arsenic uptake by common marsh fern Thelypteris palustris and its potential for phytoremediation.
    Author: Anderson L, Walsh MM.
    Journal: Sci Total Environ; 2007 Jul 01; 379(2-3):263-5. PubMed ID: 17113631.
    Abstract:
    Hydroponic and soil cultivations of Thelypteris palustris, the common marsh fern, were used to investigate its potential for use in phytoremediation of arsenic (As) contaminated water or soil. ICP-MS analyses indicate that both roots and fronds accumulated arsenic in levels up to 100 times the concentration of treatment solutions of 250 microg/L and 500 mug/L arsenic, but values varied widely and there was no significant difference in concentrations in fronds between the control (no arsenic) and treatments. Plants exposed to 500 microg/L exhibited necrosis in their fronds, suggesting that Thelypteris palustris is not a good candidate for phyotoremediation of arsenic-contaminated sites.
