| Description |
Pteris vittata L. subsp. vittata, a potential arsenic hyperaccumulator fern, growing naturally
in the vicinity of fly ash was analyzed for the concentration of nine heavy metals (Fe, Cu, Zn
Ni, Al, Cr, Pb, Si, and As) from five different sites around of Kanti Thermal Power Station
at Muzaffarpur in Bihar State, India. Metal accumulation in P. vittata was correlated with
the level of pollution at five selected sampling sites. The results revealed significantly more
accumulation of these metals in the above ground parts of the plant than the parts below
ground. Statistical parameters such as the coefficient of variation (CV%) showed a higher
for As, Cu, Cr, and a lower one for Fe, Ni, Al. There was high spatial variability in the total
metal concentration at different sites. The present study confirmed that P. vittata is a heavy
metals accumulator and that it is a highly suitable candidate for phytoremediation of metal
contaminated wastelands.
