Payton - CPAYT H. Bergen - USERS . W. K. Johnson - WJOHN Attached is a Xerox copy of a technical paper which Scott Tucker and I picked up In Washington recently. This was provided ua~ . by Donald A. Spencer of the national Agricultural Chemicals Association. Mr. Spencer requested that the paper be held "confidential" until such time as it nay be published. Spencer Indicated that If this paper were distributed one of hla principal "sources" v;ould refuse to give him prepubllca- tlon Information In the future. . Rlscbrough's presentation (the attached) was made at q meeting of 20 to 30 toxicologists held at the University of Rochester In June. The meeting was billed as "The First Annual Conference . on Toxicology" end was underwritten presumably by the AEC which has had contracts at Rochester for many years. Attendance . was by invitation only. The meeting dealt "exclusively" with pcstlcidea with abt^it one-third of the papers relating to mercury. As far as Spencer knows the papers, including the attached, will undoubtedly be printed as proceedings of the conference although I suspect Individual authors were given permission to publish elsewhere.. In a fow word's, Rlsebrough has found PCI-3s along with chlorinated pesticides In a number of species of fish and birds along the California coast as well as in waters off Baja California end Central America. He further roports FCIJ In fish from the Channel Islands and Puget Sound. No FC3 was detected in the liver of tuna taken in the Galapagos Archipelago. Soott Tucker Is going to scrutinize the analytical aspects and particularly the validity of some of the assumptions made by the author. , OB Attachment Elmer P. Wheeler * MUNS U9814J r
