Abstract

The bioremediation approach on a business scale has notable advertising and marketing possibilities nowadays. It is a common perception in the science community that in forthcoming days, when the remediation cost of contaminated land may raise many times, phytoremediation gives a value-powerful answer for in situ remediation of the tainted sites compared to different traditional techniques like excavation and reburial of infected soil. It progresses without troubling the indigenous population of the soil micro-flora and fauna and entails exploiting the herbal capacity of the surroundings to rehabilitate itself. This approach can deal with several forms of insecticides, metals and petroleum hydrocarbons. Plants also support the metabolic activities of microbial communities in the rhizosphere via the root exudates, which enable the microorganisms to break down a broad category of organic chemical compounds. Phytoremediation also encompasses several detrimental consequences as it mainly depends upon the depth of the roots and the tolerance of the plant to the contaminants. Contaminants in senescing tissues may be released back into the soil and water environment during the falling of leaves. Phytoextraction does not exclusively mean that there is the destruction of contaminants, however as a substitute can collect or immobilize the contaminants.
