This review study is based on the overall Phytoremediation technique which is considered as an ecofriendly, cost –effective method to clean the environment. This is the technique in which we can reduce amount of pollutants from soil, water and air with the help of certain plants. Nowadays, environmental pollution by heavy metals like Pb, Cd, As, Hg, Cr, Cu, Zn, and Sn has become a serious issue in the world. To degrade these heavy metals or to lower their concentrations beyond their threshold limits, phytoremediation is found to be very promising solution. Phytoremediation implies various techniques to degrade, metabolize or immobilize the heavy metals. The technique includes Rhizofiltration, Phytostabilization, Phytoextraction, Phytovolatilization and Phytodegradation. This review was focused on different phytoremediation experiments studied by different scientists. Review specially focused on heavy metals and their remediation techniques.
