Introduction, advantages and disadvantages of phytoremediation main techniques

The rapid increase in population coupled with fast industrialization growth causes serious environmental problems particularly soil pollution. Trees and plants play an important role in the earth, and in different ways they refinement weather and eliminate environmental pollution. Phytoremediation technology is a cost effective and environmentally and ecologically friendly as it utilizes plants natural ability to suck the pollutant present in the soil. There are many plants having this natural ability to up take the heavy metals and organic pollutants from air, soil and water. Phytoremediation, Phytoextraction or phytominig, Phytostabilization, Rhizofilteration, Rhizodegradation, Phytovolatilization are evolving as a cost-effective alternative to high-energy, high-cost conventional methods. Therefore, the process of remediation using micro-organisms represents a promising, largely untapped resource for new environmental biotechnologies. In the present review, current knowledge about the phytoremediation and its basic techniques are discussed.
