A Review on Purification of Yamuna River Water by Native Plants and Trees

Yamuna River is the lifeline of Delhi as it caters all the domestic water supply, irrigation, industrial, agricultural and other requirements. However the water quality of Yamuna is continuously deteriorating due to the direct/ indirect discharge of domestic sewage, industrial and agricultural effluents. It was observed that among the other pollutants, river water has very little ability to deal with heavy metal ions by self purification process. In this paper, we review the natural and self purification of both organic and inorganic pollutants in Yamuna River by phytoremediation. The native plants and trees have a great potential in purification of polluted water. So we discuss about the potential of some locally available native plants, weeds, herbs, woody plants and trees for the phytoremediation of the heavy metals present in Yamuna River.
