As environmental issues become more and more stringent, the biotechnological approaches to maintain clean environments are receiving increasing attention. Heavy metal pollution is of great concern as it ultimately forces heavy metals into the food chain leading to serious ecological and health problems. Removal of excess heavy metals from contaminated sites could be achieved by means of organisms that bioaccumulate heavy metals without developing toxicity symptoms, features that are characteristic to hyperaccumulating plants. This review focuses on the applicability of hyperaccumulation phenomenon to heavy metal boremediation as well as on the possibility to extend the hyperaccumulation concept to organisms other than plants.
