Remediation of Polychlorinated Biphenyls (PCBs) through Bio and Phytoremediation in the Environment: A Review Study

Abstract

One of the persistent organic pollutants (POPs) utilized globally between the 1930s and 1980s was polychlorinated biphenyls (PCBs). Even though their usage has been severely constrained, a lot of PCBs are still present in the environment, including soils and air. This local, national, international and governmental organizations regarding polychlorinated biphenyls and how can resolve and treat the problem sustainably. This can be achieved if seriously working on degrading persistent organic pollutants, especially polychlorinated biphenyls biologically via thorough research and sound implementation. The methods opted for remediation by the use of choosing suitable types of microorganisms and plants. These methods are practically active for the identification of the source, concentration level and effects on the ecosystem. It would help in developing appropriate strategy and data generation in formulating the inventories for the management of polychlorinated biphenyls in the future. It is also noted through numerous research that polychlorinated biphenyls are also found in human blood commonly analyzed by indicator congeners such as PCB 138,153, 180, and in air and soil markers of PCBs pollution include PCB congeners 28, 52,101,138,153 and 180 as well. The methods and mechanisms described for degrading the persistent pollutant in this research review the solutions for mitigating PCB pollution in an environment. The best option is to strictly ban it in Pakistan or weightage its usage with its multiple benefits and disadvantages. Promote biological treatment if the payback is healthy and environmentally sustainable.
