Around the world, we observe an increase in the number of contaminated soil, groundwater as well as surface water. These contaminants arise due to human activities that revolve around the industrial and agricultural sector. Some contaminants arise due to military activities as well. If conventional methods were to be used for remediating these contaminants, then the cost that would be added will be too huge. Moreover the potential of these methods is very limited and they can be applied only to small areas.

Phytoremediation refers to the methods and techniques by which living plants are used to clean up the environment which includes the air, soil and water which may be contaminated with harmful chemicals which on entry to our system can be even fatal. [1]Hence they are hazardous and needs to be remediated. The technique of phytoremediation makes use of the ability of certain plants to take up these contaminants. Some of these plants can take up these hazardous contaminants and accumulate and concentrate it within their tissue whereas others are capable of degrading or breaking down the contaminants and some might even convert them to harmless materials to the environment.
Phytoremediation can be used as an alternative technique to these conventional methods or else it can be used as a complimentary technique. This is an in situ technology in the sense that it is done at the contaminated site and makes use of the plants
