Reference your memo of August 15th, Alf Vodden has had some contact with the Bayer technical people and they have promised to come back to us after the vacation period. We will follow this up again but I don't expect anything more positive until early September. To speed things up we are attempting to arrange an exchange of samples through the commercial channels and will send these on to you as soon as we get them. From the preliminary discussions it seemed that Bayer had not done any serious in-house work on the analysis of dibenzofurans in PCBs. Predelec were even less forthcoming and didn't want to commit. Now that Risebrough's paper has appeared in Nature we may see more interest by the European PCB producers. We w^ll keep you in the picture. Regards, R.A Baxter HONS 206961
