dc.description.abstractIdentification and screening of wild, wasteland plants for the remediation of heavy metal contaminated soils is a crucial phytotechnological approach. In a pot experiment, Chenopodium murale was tested for the phytoextraction of lead (Pb) from the contaminated soils. The experiment was conducted for 8 weeks to appraise the effect of varied Pb regimes (300, 400, 500 mg kg?1) on the bioaccumulation and physiological responses of C. murale plants. At 500 mg kg?1 Pb regime, the concentration of Pb in roots and shoots reached a maximum of 2513 and 2301 mg kg?1 DW, respectively. The plants highlighted a very high tolerance with 100% survival towards Pb toxicity, although exhibited a slight decrease in biomass yield, chlorophyll content and protein levels. However, a dramatic mount in H2O2 content, MDA level and bio-activities of antioxidant enzymes (SOD, CAT and POD) was noticed. BCF and TF values were more than unity at all the Pb regimes. Results were scrutinized, accentuating the profit of raising C. murale in Pb-contaminated soils as this plant species can be a promising candidate for soil remediation and their restoration purposes.en_US
