Steenrod - St. Louis I ii .i, ; He recently sent you a translation of a Swedish newspaper * article referring to the identification in nature of polychlorinated biphenols. Because some of the uaes claimed.. for the materials fell in line with the uses of our own chlorinated diphenyls, we made a point, during our recent visit,to Sweden, of visiting the research institute involvedand discussing their particular programs of work. ' . . - . To eliminate any earlier confusion that there nay have been. . I~ ar.ouAa like co~eiT.3nas.vse that there is no .doubt ~cf.aC**the cr.emj.cai which n the subject of the investleaden. and the_ news releaae, is chlorxnacaa drpnenyl i.e. ~Aroclor. ,, * * * The company that supplied the mass spectrometer which war used in the research programme, in fact have recently put'out a prass release on this work. Although Z aa horrified by soma of the headlinas in this prass rslesso, it does basically describe tha research programme carried out in Sweden, and describes in clsar terms how chlorinated diphenyls wars identified. Z thsrafore, snclosc a copy for your files. . . ' Jansens only ala in life as an analytical chemist, was to identify the substances found in his research work on tha occurrence * of insecticides in nature. The unfortunate'aspect of the situation is the comments which have been added to Jensens work. Ha showsd what was present and unqualified people have made statements as to the possible effect of what he has found. Summarising the publication position, there were original articles covering the Stockholm conference in the Swedish daily press, and these reports were picked up also by the Danish prass. You will have seen from D.V.N. Hardy's memo of the 12th January that *it has also been picked up by the Shell Chemicals Laboratory in Kent, tJ.X. Jensen also divulged that he Had bean contacted by the Swedish American press agency who intended to include information about this research work in their monthly review The Swedish American Journal-. Those is additionally the , prase review issued by LKB Predactor AB which I imagine to - have been sent to .a number of. technical journals. PRR 050491 05O9T* SC.H / gum no. v 7 R.(L _ /yVy^ v.

Fortunately thara has not baaa too much adverse comment as yet from plant workers sinca . ; they hava not associated the polychlorinated biphenols mentioned- - . in tha article with Aroclor or Pyralene used in the Swedish factories.

Arrangements are bain? made in Sweden for this work to be taken over by one of the medical inatitutca who hope study * tha toxicology of the polcychlorinatad diphenyl residues-at tha layals of concentration found by Canaan. Additionally ' a geographical survey is to be carried out to try and datarains Where tha highest concentrations of resides are appearing' and, if possible, to detect from this tha nethod of escape so that mors security precautions can be taken. We were asked by Jenson if it was possible for Monsanto to supply any samples of tha pura isomers of chlorinated diphenyl since bis work indicated at tha moment that tha lower chlorinated isomers - ears fairly easily metabolised, and the potentially more dangerous conatituenta are the more highly chlorinated members. If he dan get hold of pure isomers, ho would like to carry . out some work on compsritive rates of astabolisation. f Jensen is forwarding me copies of his mess spectrographs end details of.sample preparation so that we have ail the details ' . of his research work. . __ j , .' The point tfcetTx have . :d# to Jensen is the need for'care in any further publicatit: of his work which is mads. Re accepts ' that.the toxicology of chlorinated diphenyls should only be dlseuased with detailed information about exposure concentrations . and exposure times end that generalised statements out of context can only arouse undue public concern. Zf any technical journal takas up the press release from the LKB Productor Company# there is little that Monsanto could, or should do. in the way of publishing rebuttals. Ws do not want, personally as Monsanto to get too involved in this question. Z am hopeful that we PAR SCM 050979 050*92 ' . /- 1 r HARTOLDMONOO11718 } >w ; J3 > ....
