Phytoremediation is an in situ, solar-powered comprehensive
strategy for bioremediation of environmental problems by using
plants and their associated microorganisms to extract, sequester, or
detoxify pollutants. The plants mitigate the problems; environmentally invasive excavation of the contaminated material to dispose of
it elsewhere is avoided. Plants are able to contain, degrade, or eliminate metals, pesticides, explosives, solvent, crude oil, and many
industrial contaminants. Phytoremediation requires minimal disturbance and maintenance of a site and is a clean, cost-effective,
environmentally friendly technology, especially for treatment of
large contaminated areas with diffuse pollution. Many successful
examples of phytoremediation are documented and employed in
the environmental cleaning industry (Macek et al., 2000; Suresh
and Ravishankar, 2004)
