Due to their toxic nature, heavy metallic contamination has become the most hazardous pollutant in the growing world. Therefore, reduce or remove water contamination is the predominant importance. Utilization of plants to refine water quality is a green technology, which is an effective method, environment-friendly and consumes fewer energy inputs, and also carried out less amount of cost. In this review article, we enlighten the potential of various aquatic macrophytes to reduce or remove the heavy metal contaminants from the aquatic eco-system.</span></span>
