"TT rSytoh "-"OMIT ' H. Bergen - HBERO W. K. Johnson - WJOHH FP Attaohed Is a Xerox copy ol a technical paper which Scott Tucker and I picked up in Washington recently. This was provided us by Donald A. Spencer of the National Agricultural Chemicals Association. Mr. Spencer requested that the paper be held "confidential" until such time as it may be published. Spencer indicated that If this paper were distributed one of his principal "sources" would refuse to give him prepublica tion information in the future. Rlaabrough's presentation (the attached) waa made at a meeting of 80 to 30 toxicologists held at the University of Rochestar In June. The meeting waa blllsd as "The First Annuel Conference on Toxicology" and was underwritten presumably by the AEG whlcn has had oontrsots at Rochester for many years. Attendance wee by invitation only. The masting dealt "exclusively' with pesticides with about one-third of the papers relating to meroury. As far as Spencer knows the papers, including the attached, will undoubtedly be printed as proceedings of the conference although I suspect individual authors ware given permission to publish elsewhere. t ) In few words, Rlsebrough has found FCBs along with chlorinated pesticides in a number of tpeclea of fish and birds along the California coast as well as in waters off Baja California and Cantral America. Hs further reports PCB in flab from the Channel Islands and Puget Sound. Ho PCB was detactad in the liver of buna taken In the Oalapagos Archipelago. Scott Tucker la going to aorutlnixe the analytical aspects and particularly the validity of some of the assumptions made by the author. ot Attachment Elmer F.
