Metal Hyperaccumulating Ferns: Progress and Future Prospects

Sarita Tiwari, Bijaya K. Sarangi, Pulavarty Anusha and Ram A. Pandey

Abstract

Environmental exposure to heavy metals such as arsenic and chromium has become a serious problem worldwide. The recent advances in the knowledge of metal hyperaccumulation by some plant species have recognized phytoextraction as a prospective proposition using hyperaccumulator plants. This paper enumerates the progress in phytoextraction of metals using fern species with emphasis on the arsenic hyperaccumulator Pteris vittata. The scopes of R&D for value addition in ferns for efficient phytoremediation application have also been discussed.
