Phytoremediation is an ecofriendly that has shown promising results for the contaminants like heavy metals. Because of its advantages as a cost-effective, efficient, environment- and eco-friendly technology based on the use of metal-accumulating plants. This paper aims to compile some information about heavy metals of arsenic, cadmium, lead, copper and zinc (As, Cd, Pb, Cu and Zn) sources, effects and their treatment. It also reviews deeply about phytoremediation technology, including the heavy metal uptake mechanisms and several research studies associated about heavy metals (As, Cd, Pb, Cu and Zn) and aquatic plants are used to process these heavy metals.
