t . Tokyo . March 16, 1672 . TOXICITY OF CHLORINATED BENZENE- MfttNCC l 'TO i Mr. V. B. Papageorge . ' St. Louie As you know well, MMKh'ps decided to discontinue manufacturing end selling PCB's. In line with this decision we have been talking with our PCB users. Local PCB users are rather sure, Judging from MITI's rigid policy toward PCB's, that It will be quite difficult for them to continue using PCB in the future and they are now actively looking for substitutes for PCB's. In thlR connection, Mitsubishi Electric Co. bns asked us whether we Could make available* to them any toxicity data on chlorinated benzen compound which seems, they think, to be a promising substitute for PCB as non-inflammable Insulating oil. It would be greatly appreciated, if you would provide us with MC Information or any published data on chlorinated benzene with respect to its 1) chronic toxicity and 2) deg- radntlon in the living body as In the case of PCB. Thank you for your cooperation. Bincerely yours YO:rl S. Uneno Product Director Division C MQNS 099 703
