Remediation Technologies for Soils Contaminated by Polychlorinated Biphenyls (PCBs)-A Review

Aneeqa Wazir, Imran Hashmi

PCBs can be present in degraded soils and sediments when they have been specifically regulated for use. Because of their perceived value and outstanding physical-chemical properties, some 1.2 million tons of overall PCBs have been developed and commonly used in production such as coolants, transformer lubricants, pesticides, etc. This natural for PCBs to cause a number of individual, livestock, food, and laboratory harmful reactions in organisms. Microbes are the main players of PCB depletion, carried out under both aerobic and anaerobic conditions. Microbes and plants communicate strongly inside the rhizosphere. Microbes may promote plant growth under stressful conditions that are characteristic of contaminated soils. This study discusses the new insights that continue to arise from recent studies, especially regarding both the capacity for rhizosphere in bioremediation of PCBs and the deployment of simultaneous aerobic and anaerobic degradation processes.
