“…Thus, last decade has gained tremendous momentum in the field of phytoremediation, and this approach has now entered into active field of development (Macek et al 2000;Divya and Kumar 2011). Several plants including pine tree, alfalfa, flatpea, willow, canarygrass, deertongue, switchgrass, tall fescue, poplar, tobacco and mustard among others have been tested for their efficiencies to reduce PCBs in spiked soils (Ficko et al 2010;Ionescu et al 2009;Meggo et al 2013). Low bioavailability in soil often results in limited utilization of PCBs by plants.…”

Synthetic organic compounds are hallmark of modern society. They are ubiquitous ranging from home, workplace to agriculture industry, which leads to their nonjudicious dispensing into environment. Unfortunately most of them, especially polychlorinated biphenyls (PCBs), are deemed as persistent organic pollutants posing serious health risks to human. Hence, there is an alarming need of phasing out these chemicals and remediating contaminated sites in eco-friendly manner. Phytoremediation has emerged as a highly promising approach which capitalizes on plants and their associated microorganisms for removal of pollutants from targeted sites. Plant root exudations and secondary metabolites efficiently orchestrate selective recruitment of potential PCB-degrading microbial consortia within the rhizosphere and inside plant tissues. Structural analogy between organic contaminants and secondary plant metabolites (SPMEs) renders possible uptake and subsequent degradation of pollutants by microorganisms. Present review is focused on potential role of plant root exudates and SPMEs in structuring and orchestrating remediation of PCBs within rhizosphere and inside plant tissues. Also, recent developments in tools and techniques to study remediation of organic contaminants with special reference to PCBs are addressed.

“…As stated previously, studies have shown the uptake of PCB's (Zeeb et al 2006;Ficko, Rutter, and Zeeb 2010) and dioxins (Huelster, Mueller, and Marschner 1994) into plant tissue. But PCB metabolism in plants is slow and dioxins have not yet been shown to degrade within the plant (Campanella, Bock, and Schröder 2002).…”

“…Alfalfa and other plant species have been shown by several studies to extract PCBs from soil or water (Zeeb et al 2006;Ficko, Rutter, and Zeeb 2010;Xu et al 2010;Ying Teng et al 2010;Liu and Schnoor 2008;Greenwood, Rutter, and Zeeb 2011). Chlorinated dioxins can also be extracted from the environment using plants (Campanella and Paul 2000;Huelster, Mueller, and Marschner 1994).…”

“…Most phytoremediation research has focused on a single contaminant (Blaylock et al 1997;Campanella, Bock, and Schröder 2002;Cook and Hesterberg 2013;Cordale Johnson, John Thomlinson 2009;D'Orazio, Ghanem, and Senesi 2013;Duckart, Waldron, and Donner 1992;Ficko, Rutter, and Zeeb 2010;Newman et al 1997;Wei et al 2009), but field sites often contain multiple contaminants, and phytoremediation with a variety of plant species could better contribute to ecological restoration of a site. Such ecological restoration would best be accomplished using species of plants indigenous to the site.…”
