Queeny St. Louis St. Louis St, Louis With reference to your letter to Dr. Baxter w note that your available quantities of d- and trlahlorobiphenyl isomara are very small indeed. As you know v hav already provided samples for Jensen and Vidmaxk (Stockholm), Richardson (Shell, England) and T&tton (Govarnoant Laboratory, England), and the reeldual quantities are now to be reckoned in terns of milligrams. We assume you will be writing appropriately to the SyracusdUniveruity Research Corporation. . On your request for information concerning the testa mad by tha above workers on our samples I can summarise m followsi~ . (a) Jensen and Widnark I have seen no development sinos Widnark's latter of February 27th 1967 addressed to Gan Wild. (b) Patton Copies of a paper entitled 'Chlorinated Hydrocarbons in British . Wildlife* by D.C. Holms, J.H. Simons and J.O'C. Patton, Nature Vol 216, Oct 21, 1967 pp. 227-229 were passed to Masars. Wild and Buohanan with my latter of 4th November, 1967* This paper eonfirms the work of Jenson and in particular shows cloaa similarity between gas-liquid ahromatograms of (a) xtrsadis of Kestrel liver oil and (b) a commaroial polyehlorobiphaayl resin. (o) Rjchagdeon Richardson has not published anything so far, but J. Robinson, also of Shall Research Ltd., Tunst&ll Laboratory, Sittingbourr, Kant has . published a paper entitled 'Residues of Qrganochlorina Inaactioidas in Dead Birds in tha United Kingdom, Qsamistxy and Industry 1967* PP* 1974-1986. This is a comprehensive review but as far as I oan see it doe not suggest that any of tha residues contain chlorinated polyphanyla. However, I was in orraspondanoe with Rioh&rdscn in November, 1967 (copies herewith) whish showed that he was satisfied that ootoehlorobiphenyl was present and that his results are substantially in lira with those of Tattcin at al. You will note also that ha believe that the oontamination of bird life is in tha valley of asr Rivar Withaa. ...... I have Judieiously followed up this olu with a view to locating tha source of th contaminations there appears to be no operation of say aiz involving Aroolora within th Witham vaSay. Th nearest is at King Lynn with usa^ for olectrieal purposes. As ICR represents the greatest off-take of Aroelor and as there is likely to b at least ease wastage in tha process my suspicion is that it is either in making NCR or possibly in dealing with th* scrap that tha oontamination arises. ' COMPANY" there is no indication that th Publio Authorities axe worried. CONFIDENTIAL TRAN 086030 WATER PCB-SD0000076391
