5. **Phytodegradation**

Phytodegradation technique refers to the degradation of organic contaminants through the enzymatic activates of plants. The plant releases enzymes from roots, or through metabolic activities within plant tissues. In phytodegradation organic contaminants are taken up by roots and metabolized in plant tissues to less toxic substances [26]. Phytodegradation process can degrade hydrophobic organic contaminants more efficiently.
