Abstract

This study investigates the impact of different concentrations of citric acid and EDTA treatments on Duranta erecta's response to polluted soil conditions. The results indicate that both citric acid and EDTA treatments positively affect Duranta erecta's growth, with chelator-treated groups showing improved growth metrics compared to the control. Citric acid at 1.0 gm kg-1 soil concentration leads to the highest shoot fresh weight of 63.16 g and shoot dry weight of 12.70 g, while EDTA at 0.5 gm kg-1 soil concentration results in a shoot fresh weight of 55.16 g and a root fresh weight of 40.00 g. Moreover, both chelators influence the uptake of heavy metals by Duranta erecta. The control group exhibited elevated levels of Zn (152.48 mg kg-1), Ni (123.00 mg kg-1), and Pb (192.00 mg kg-1). Citric acid at 1 gm kg-1 soil concentration reduced Zn to 125.51 mg kg-1, Ni to 86.69 mg kg-1, and Pb to 137.80 mg kg-1. EDTA at 1 gm kg-1 soil concentration showed more substantial reductions, with Zn at 64.50 mg kg-1, Ni at 75.15 mg kg-1, and Pb at 113.54 mg kg-1. Evaluation of phytoremediation efficiency through bioaccumulation factor , translocation factor , and remediation efficiency confirms the efficacy of both chelators in enhancing the uptake and translocation of heavy metals. EDTA treatments show higher bioaccumulation factor values (2.74) for zinc and 1.95 for nickel (Ni) at 1 gm kg-1 soil concentration. These findings suggest citric acid and EDTA treatments have potential applications in phytoremediation of heavy metal pollution
