Abstract : The rapid expansion of industrial activities has led to increased discharge of heavy metals into aquatic ecosystems, posing severe risks to human health and the environment. Conventional wastewater treatment methods often suffer from high operational costs, secondary pollution, and limited efficiency. In recent years, green-synthesized nanoparticles have emerged as a sustainable and eco-friendly alternative for the removal of heavy metals from industrial wastewater. These nanoparticles are synthesized using biological resources such as plant extracts, microorganisms, and biopolymers, eliminating the need for toxic chemicals and energyintensive processes. Owing to their high surface area, tunable surface chemistry, and enhanced adsorption capacity, green-synthesized nanoparticles demonstrate remarkable efficiency in removing toxic heavy metals including lead, cadmium, chromium, mercury, and arsenic. This approach not only improves metal removal efficiency but also aligns with the principles of green chemistry and sustainable development. This review highlights recent advances in green synthesis methods, mechanisms of heavy metal removal, performance evaluation, and future prospects for large-scale application in industrial wastewater treatment.
