Abstract: Heavy metals generally have been of remarkable concern to researchers and scientist. Lead is one of theheavy metals with no biological value to plants, animals, and humans. Hence like other heavy metals in suchclass (Cadmium, Arsenic, and mercury) could be toxic even in little concentrations. Lead is described as themost important toxic heavy metal in the environment. Due to its important physico-chemical properties, its use can be retraced to historical times. Due to its non-biodegradable nature and continuous use, itsconcentration accumulates in the environment with increasing hazards (Nas and Ali, 2018; Babu et al 2021,Offor et al 2024). In plants, lead affects several processes, including photosynthesis. Same plants however can take up lead and serve as decontaminating organism for lead in soil. Several researches have establishedhigh concentrations of Lead and other heavy metals in plant tissues, both edible and non-edible parts (Offoret al, 2020a, Offor et al, 2020b) .Decontaminating soil from toxic metal pollution sometimes could be time-consuming and expensiveprocess. Toxic metals pose a serious threat to human and animal health because of their long-termpersistence in the environment (Tica, et al 2011; Babu et al 2021). The removal of significant amounts ofheavy metal contamination using other processes could be costly and results in massive economic waste.Phytoremediation is a practical, dependable, eco-friendly, long-term practicable, and cost-effective methodof decontaminating an area from toxic heavy metal pollution (Placek, et al 2016; Babu et al 2021).
