The prolonged duration of phytoremediation poses a risk heavy metal dispersal to the surrounding environment. This study investigated combined remediation approach for cadmium (Cd)- and arsenic (As)-contaminated soil by integrating with stabilization techniques. Bidens pilosa was utilized as phytoremediator, steel slag, pyrolusite, FeSO4 were employed stabilizing agents in pot experiments. Key metrics such moisture content, root length, plant height, concentrations measured evaluate efficacy. Additionally, bioavailability, leaching toxicity, chemical forms Cd As, along other properties, analyzed. results indicated that optimal restoration effect achieved combining stabilizers ratio 2:1:10. dosage these materials found be 9% weight. Mechanistic studies, including speciation analysis, X-ray photoelectron spectroscopy (XPS), microbial community diversity revealed effects primarily due interactions anionic cationic ions, chelation organic acids secreted roots, enhanced activity. A cost–benefit analysis demonstrated technical, economic, commercial viability approach.
