BIOREMEDIATION OF PAHS CONTAMINATED AGRICULTURAL SOIL-A REVIEW PAPER

Soil is an important environmental matrix that directly or indirectly supports the life of all creatures. Despite being the ultimate sink for all contaminants, it has been neglected for a long time, resulting in poor soil quality. Due to the contamination of various toxic polycyclic aromatic compounds (PAHs) in soil, it diverts the quality of soil and impacts the soil ecosystem. Henceforth, it is necessary to identify the ecologically sustainable treatment alternatives for contaminated site cleanup. Biological treatment of PAHs contaminated soil is emerging as a promising and sustainable treatment options because they are safe, cost effective and eco-friendly treatment solutions. When it comes to pollutant degradation, microorganisms are known for their enzyme-catalyzed catabolic activity, w hich can be advantageous in the decomposition of PAHs. There are various microbes which are extensively used for the removal of PAHs, in which This review paper compiled a various recent in-situ and ex-situ bioremediation techniques used for the degradation and remediation of PAHs in agricultural soil.
