Phytoremediation is an environment friendly alternative to current remediation technologies. Although this technology is not new but current trends suggest that its popularity is growing. This article reviews some techniques of phytoremediation namely phytostabilization, phytoextraction, rhizodegradation, phytofiltration, hytodegradation, phytovolatilization and hydraulic control along with discussions about its advantages and disadvantages and some factors for testing of phytoextractors.
