Norback Veterans Administration Hospital 2500 Overlook Terrace Madison, W1 53705 RE: PCBs Dear Dr. Norback: Sometime ago, Bill Ribelin contacted you regarding some of the studies you had conducted with PCBs. I had requested that information for a review that 1 was writing on the carcinogenicity and mutagenicity of PCBs. This is a somewhat belated thank you for the information which you had supplied. It is also an opportunity for me to rectify an oversight, i.e. sending you a copy of the review which has been completed. In addition, I am sending you a second report which discusses observations on liver pathology from rats fed PCBs and a Monsanto bulletin on polychlorinated biphenyls. On page 4 of section 2 of the bulletin, there is a discussion of Jim Allen's primate studies with PCBs and a reference to a related Monsanto study. This may be of interest to you. The two Monsanto reports have been submitted for publication. Notwithstand ing that, I would appreciate your reaction to, or any comments you would care to make, regarding them.
