Identification 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.

鉴定和筛选野生，荒地植物以修复重金属污染的土壤是一项至关重要的植物技术方法。在盆栽实验中，测试了Chen藜（Chenopodium murale）从受污染的土壤中提取铅（Pb）的植物。实验进行了8周，以评估不同的Pb方式（300、400、500 mg kg ^-1）对虫植物生物积累和生理响应的影响。在500 mg kg ^-1 Pb的条件下，根和茎中的Pb浓度分别达到2513和2301 mg kg ^-1的最大值。DW，分别。植物显示出很高的耐受性，对Pb毒性的存活率为100％，尽管生物量产量，叶绿素含量和蛋白质水平略有下降。然而，注意到H ₂ O ₂含量，MDA水平和抗氧化酶（SOD，CAT和POD）的生物活性显着增加。在所有的Pb方案中，BCF和TF值均大于1。对结果进行了仔细检查，从而强调了在受Pb污染的土壤中养成C. murale的益处，因为该植物物种可以作为土壤修复及其恢复目的的有前途的候选者。
