Bioremediation is “the use of living organisms for removal of a pollutant from the biosphere” It relies on biological process to minimize an unwanted environmental impact of the pollutants. The microorganisms in particular have the abilities to degrade, detoxify and even accumulate the harmful organic as well as inorganic compounds. Besides them, Higher plants have also been reported to remove such pollutants primarily through their ability to accumulate these in their tissues Bioremediation has emerged during resent past as the most ideal alternative, environment friendly and ecologically sound technology for removing pollutants from the environment, restoring contaminated sites and preventing further pollution. This technology has the potential to be more socially acceptable when compared to physical or chemical process and is therefore expanding the range of organisms to be used for pollution cleaner. Bioremediation in fact forms a vital component of the so called green movement of maintaining the natures overall ecological balance, an issue of top priority of environmental awareness and public policy. The objective of this abstract is to focus on how do plants remediate contaminated sites. Phytoremediation is an attractive remediation technology for removing hazardous substances from soil sediments, surface or ground waters contaminated with municipal or industrial wastes etc. This use of plants for environmental desperation is an emerging cost effective clean up technology suitable for broad range of contaminants including metals, radio nuclides and organics. Green plants are not only the lungs of nature with an ability of purifying impure air by photosynthesis but some species have also be unique ability to uptake, tolerate and even hyper accumulate heavy metals and other toxics substances from soil and water through their roots and concentrate them in roots, stems and leaves. These include some aquatic weeds such as species of salvinia, Lemna, Azolla and Eichhornia, sedges like Typha latifolia and some herbaceous as well as woody flowering plants. The author wanted to discuss in detail about the phytoremediation process. Phytoremediation relies the plant ability to act as a solar driven pump and filtering system and enhances or stimulates the natural tendency of eco system to restore itself.
