Phytoremediation Use of plants to remove contaminants from water, soil and air (yes, air!) Cost-effective and easy to maintain Can be used in conjunction with other methods 24 hour work day Phytotoxicity might be an issue Takes a long time Phytotransformatio n Phytoextraction Phytovolatilization Phytostabilization

Advantages of Phytoremediation 1. Improves the natural structure and texture of soil 2. It is driven by solar energy and suitable to most regions and climates 3. It is cost effective and technically feasible 4. Plants can provide sufficient biomass for rapid remediation; promote high rhizosphere activity 5. Restoration in a reasonable time frame - 2 to 3 years 6. > 30,000 sites in Canada where such technology is needed, > 300,000 sites in the US 7. Can be used effectively at remotes sites
