Elmer P. Wheeler, Medical Department January 29, 1970' J. S. Barrett, London W OrBinui,1 IttJtim ' W. B. Pepageorge, WPAPA Enclosed Is a copy of the reports from our consulting laboratory Indicating the status of the animal toxicity studies. I have summarised the pertinent findings separately and aa Indicated In the table. We have given copies of these data to one 0. S. custo mer, the U. 8. FDA and one or two other state agen cies. I don't see why this Information cannot be released with discretion In Britain or Europe. Our Interpretation Is that the PCB's are exhibiting a greater degree of toxicity in this chronic study than we had anticipated. Secondly, although there are variations depending on species of animals, the PCB's are about the same as DDT In mammals. We have additional Interim data which will perhaps be more discouraging. We are repeating some of the experiments to confirm or deny the earlier findings and are not distributing the early results at this time. EPW:Ju Enclosure Elmer F. Wheeler HONS 098480
