| Abstract: | Characteristics and pathways of photodegradation of polychlorinated biphenyls (PCBs) in various solutions are reviewed. Dechlorination was attributed to the main pathway for PCB photolysis. In addition, hydroxylation was the minor pathway for PCB photolysis in polar solvents such as water and alcohols. The photo reactivity of PCBs was related to the position and quantity of chlorines on the PCB congeners. The application of photolysis in remediation of PCB contaminated soils is also briefly reviewed. |
