PHYTOREMEDIATION OF COAL MINING AFFECTED CONTAMINATED LAND-OPTIMIZATION WITH AGRONOMICAL PRACTICES:A CONCEP- TIONAL APPROACH

Kumar Nikhil

Abstract

Coal mining resultant contamination of land which is ecologically under stress. Source of contamination associated with various mining arid allied industrial activities. Phytoremediation is an use of higher plants for the cleaning of contaminated land/soil. The selected plant species possess the genetic potential to remove, degrade, metabolize, or immobilize contaminants. Besides its tremendous potential, phytoremediation is yet to become a commercial technology. Progress in the field is slow due to limited knowledge of basic plant remedial mechanisms. Further, the effect of agronomic practices on these mechanisms is poorly understood. The effect of agronomic practices on plant/soil/contaminant interaction would optimize phytoremediation process to site specific conditions. Remediation of metal contaminated soil faces a particular challenge. Unlike organic contaminants, metals cannot be degraded. Commonly, decontamination of metal-contaminated soils requires the removal of toxic metals. Recently, phytoextraction, the use of plants to extract toxic metals from contaminated soils, has emerged as a cost-effective, environment-friendly cleanup alternative. In this paper, a conceptional approach has been discussed on phytoremediation of coal mining affected contaminated land and its optimization through agronomical practices.
