Abstract

Contaminants in the environment occur naturally and/or through anthropogenic activities. These contaminants become a threat to all living organisms because of their increased in the environment and non-biodegradable nature. In order to protect the environment from these contamination, various techniques have been developed, and among them is phytoremediation. Phytoremediation is a technology that employed plant species for reclaiming contaminated soil, air, and water. This technology has been widely accepted in recent times, because of its low cost and environmentally friendly. In addition, augmentation of the contaminated soil, either chemo augmentation or bioaugmentation, have been used for the effective absorption of some of these contaminants. When the plants are grown in the contaminated sites, the contaminant in the soil maybe removed, immobilized, degraded or volatized. These phytoremediation technologies are: phytoextraction, phytovolatilization, rhizofiltration, phyto-stimulation, phyto-stabilization and phytodegradation. Based on the phytoremediation potentials of plants, pollutants are being removed from the environment thereby keeping the environment safe.
