J.M.M. THOMSON - London 7 The only reference that I have to the pollution of the atmosphere and rivers by chlorinated diphenyl is New Scientist, 15 Dec 1966, p.6l2. I do not have any of the original papers by Dr. Jensen. I would suggest that you contact Dr. Hardy who deals with toxicity questions, and was directly involved. CRc COLIN R. COLEMAN HQNS Q9191Z
