Abstract

Due to increased anthropogenic activities pollutants in water have become a major concern. Today, when we are facing scarcity of water a systematic, eco-friendly, and cost-effective treatment of wastewater are pre-requisite for the growth of the economy. Nanotechnology and phytoremediation are a hand-full of emerging technology for the efficient elimination of pollutants like heavy metals and organic pollutants from wastewater. Plant species used in nano-phytoremediation are hyperaccumulators and metal tolerant, for example, Cynodon dactylon (Bermuda grass), Eichhornia crassipes (water hyacinth), Helianthus annus (sunflower), etc. Some organic pollutants, for example, long chain hydrocarbons and organohalides, become resistant to previously used degradation methods. Nano-phytoremediation can overcome this disadvantage using nanoencapsulated enzymes which assist rapid and enhanced degradation. This chapter focuses on the adsorption of pollutant on nanoparticles, different plant species used in nanophytoremediation and their mechanism to alleviate pollutant from water, harmful effect of wastewater pollutant on human health, and the future aspect of this approach of combining nanotechnology and phytoremediation.
