Photodegradation by sunlight is an important decomposition mechanism of polychlorinated biphenyls in the environment. Photodegradation of PCBs proceeds through successive dechlorination of the biphenyl nucleus and thus modify the proportions of the various congeners in a PCB mixture. The objectives of this work is to study the effects of sunlight on a typical PCB mixture such as Aroclor 1254, in a congener specific approach in order to observe the variations in the levels of these toxic congeners in the irradiated mixture.
