Abstract
The photochemical behaviors of six non-ortho substituted PCB congeners, i.e ., 3,4-DiCB, 3,5-DiCB, 3,3',5-TriCB, 3,4,5-TriCB, 3,3',4,5-TetraCB, and 3,4 ,4',5-TetraCB, irradiated at 254 nm in alkaline 2-propanol were investigate d. Besides the determination of the photodechlorination pathways of these c ompounds, the presence of photorearrangement was observed in the case of 3, 4-DiCB with its products being identified. The results indicate that dechl orination is much more important than rearrangement during the process of P CB photolysis. (C) 2000 Elsevier Science Ltd. All rights reserved.
