Rapid industrialization and population explosion have resulted in contaminating the environment in many ways. Heavy metal contamination from industries has raised the threat to the nearby residents by polluting soil and groundwater. Phytoremediation has emerged as an eco-friendly, long-lasting, durable, and financially practical procedure for the remediation and reclamation of overwhelming metal polluted land. The present study was undertaken to assess the accumulation of four heavy metals (Cr, Cu, Ni and Pb) in twenty naturally growing plant species viz. Abutilon indicum, Alternanthera sessilis, Achyranthes aspera, Cassia tora, Cassia occidentalis, Calotropis procera, Chinopodium ambroisoides, Croton bonplandianum, Cynadon dactylon, Cyperus rotundus, Eclipta alba, Erigeron bonariensis, Euphorbia hirta, Lantana indica, Parthenium hysterophorus, Sida cordifolia, Solanum nigrum, Tridax procumbens, Urena lobata and Xanthium strumarium in an industrial area of Uttarakhand, India. The results revealed that the heavy metal accumulation was heterogeneous among the different plant species and plant parts. Average shoot metal concentration in plants were Cr = 38.32, Cu = 33.69, Pb = 27.26, and Ni =20.27 µg g−1 dry wt. and the corresponding root metal concentration were Cr = 36.93, Cu = 24.25, Pb = 28.38, and Ni = 23.77 µg g−1 dry wt. The TF ranged between 0.30 ± 0.02 (C. rotundus) to 7.25 ± 0.02 (P. hysterophorus) for chromium; 0.37 ± 0.05 (T. Procumbens) to 9.26 ± 0.26 (U. lobata) for copper; 0.23 ± 0.01 (C. rotundus) to 11.46 ± 0.31 (P. hysterophorus) for lead and 0.51 ± 0.04 (T. Procumbens) to 7.18 ± 0.06 (U. lobata) for nickel. Ten out of twenty plant species showed translocation factor> 1for all the four studied metals suggesting their potential for the remediation of multi-metal contaminated soil.
