Abstract
Human activities increase the concentration of heavy metals in the environment from year to year. Therefore, decontamination is very important for the ecological restoration. This study investigated the phytoremediation potential of Platycerium coronarium (Fern),Vernonia amigdalina (Bitter Leaf), Chromolenaodorata, Talinumfruticosum (Water Leaf) for the removal of Ni, Cd, Cr, Zn and Cu in the goldmine tailings.Bioaccumulation factor of all element are lower than one which indicated accumulator. Translocation factor of Cd, Ni and Cr more than one and hence, Platycerium coronarium and Chromolenaodorata could be considered as potentially useful for remedying Cd, Ni and Cr contaminated soil.
