Phytoremediation was carried out with Bryophyllum pinnatum
as a means of cleaning up soils contaminated with heavy
metals. Maximum levels of metals accumulated were Ni (11.91
mg/kg), Pb (399.90 mg/kg), Cr (32.48 mg/kg), V (5.81 mg/kg)
and Cd (3.12 mg/kg) and this occurred in the 4th
month of study. Results of this study indicate that B.
pinnatum is an efficient metal hyperaccumulator for
phytoremediation of metal contaminated soils.
