Large areas of West Bengal have to rely on arsenic-contaminated ground-water for irrigation of staple crops such as rice. Phytoremediation is the use of plants to remove or render contaminants harmless in the ecosystem while Phytoextraction is the use of plants, preferably hyperaccumulators, to take up contaminants. In this work, Pteris vittata, exhibited remarkable ability to hyperaccumulate arsenic in the fronds as compared to Eichhornia. While arsenic toxicity resulted in significantly diminished biochemical constituents in Eichhornia, Pteris was comparatively less affected. This indicates that P.vittata is better equipped to tolerate arsenic stress than Eichhornia and is more suitable for arsenic phytoremediation.
