This study investigated the phytoremediation potential of Plantago major L. to remediate lead (Pb) contaminated water and soil. Results of this investigation indicated that P. major L. roots exhibit a significant increase in Pb uptake relative to P. major leaves from polluted water and soil. In polluted water (40 mg/L Pb), P. major showed unusually high concentrations of Pb in their roots (9284.66 mg/kg) within 25 days as the rhizofiltration suggesting that an exclusion strategy for metal tolerance exist widely in him. In soil, P. major has the potential for phytostabilization. In Pb-contaminated soil at 20 mg/kg, P. major roots efficiently accumulated Pb (50.53 mg/kg and 77.12 mg/kg) after 10 and 20 days, respectively. Pb was taken up by P. major leaves to a lesser extent than the roots (13.87 mg/kg and 30.4 mg/kg) after 10 and 20 days, respectively. The results suggest that P. major may be considered a bioaccumulator species for Pb and can be used as a bioindicator of pollution with lead.
