Phytoremediation means 'plant', and Latin remedium, meaning 'restoring balance') refers to technologies that use living plants to clean soil, air and water contaminated with hazardous chemicals. Phytoremediation is a cost-effective method of remediation based on a plant that takes advantage of plants' ability to concentrate elements and compounds from the environment and to metabolize various molecules in their tissues. It refers to the natural ability of certain plants called hyperaccumulators to bioaccumulate, degrade or make harmless contaminants in soils, water or air. Toxic heavy metals and organic pollutants are the main objectives of phytoremediation. The knowledge of the physiological and molecular mechanisms of phytoremediation began to emerge in recent years along with biological and engineering strategies designed to optimize and improve phytoremediation. In addition, several field trials confirmed the feasibility of using plants for environmental cleaning.
Phytoremediation is the direct use of live green plants for in situ, or instead, elimination, degradation or containment of contaminants in soils, sludges, sediments, surface water and groundwater. Phytoremediation is:
• A low cost solar energy based cleaning technique.
• More useful in sites with low and low pollution levels.
• Useful for treating a wide variety of environmental contaminants.
• Effective with, or in some cases, instead of mechanical cleaning methods.
