F. Wheeler, Manager Environmental Health Monsanto Company 800 N. Lindbergh Boulevard St. Louis> Missouri 63166 . Dear Dr. Wheeler: This will recall to you our Interest in the PCB problem and our telephone conversation of some weeks ago in which you indicated that Monsanto was pursuing research on the long term accumulation and toxicity of PCB's and your wiI Iingness to share information on the subject. I was understandably unhappy to learn from Dr. Risebrough when 1 returned from Europe that no progress had been made in this direction. As' far as I know then, the distributions of PCB's outlined by Dr. Risebrough in Chapter 1 of the book edited by Miller and Berk (Chemical Fallout, C. C. Thomas, 1969) are not in question and lacking more definitive information about their long-time effects on ecological systems, there is every reason to consider taking precautions even now. In connection with the upcoming White House Conference on Food, Nutrition, and Health, our panel is supposed to consider the future of legislation on "food safety". In order to consider PCB residues and what course the Government should take in controlling them, we would appreciate very much learning from you the present status of your observations. Very truly yours. HSO:Im cc: Dr. Kenneth H. Maddy Mr. Edward Bock Dr. R. P. Upchurch 0t. R. S. Gordon H. S. Olcott . Professor, Marine Food Science r j. Cc>on DSW 203039 STLCOPCB4052997
