Heavy metals severely affect the quality of water. Species of Salvinia are regarded as potent hyperaccumulators of heavy metals. Biotechnology will play a promising role in the development of new hyper accumulators by transferring metal hyper accumulating genes from low biomass wild species to the higher biomass producing cultivated species. Heavy metal toxicity and the danger of their bioaccumulation in the food chain represent major environmental and health problems. | Biological control of heavy metal pollutants in water by Salvinia molesta
