Abstract

Agricultural soil contamination through heavy metal is the most common event due to the indiscriminate use of agrochemicals and associated anthropogenic activities. The soil is losing the carrying capacity to supply essential nutrient elements due to adverse interaction with the toxic elements and soil microorganisms. The environmental contamination, biomagnification of food chain and associated health risk is the major concern in recent decades seriously affecting the soil health and future generations. In this scenario, phytoremediation is a green approach to tackle the soil contamination and reversing soil degradation. Plant response to heavy metal and efficacy of remediation of contaminated soil depends on plant and soil characteristics. In this context, hyperaccumulator plants can be effectively used to extract and remove large concentrations of toxic metals from the contaminated systems. Traditional methods of phyto-remediation approaches are not economical and not suitable for the large area decontamination, however hyperaccumulators are promising that can be integrated with the efficient microbes for better results. In the recent advancement of genetic engineering approach to develop transgenic plants with characters of high biomass production, more metal accumulation, tolerance against metal toxicity and well adapted to a variety of climatic conditions might be more beneficial in this respect. Other more modern methods of phytoremediation include chemically aided phytoextraction andmicrobes assisted phytoremediation using potential endophytic microorganisms to decontaminate polluted soils on large scales.
