Tuesday, March 25.1975 The Journal. Lorain, Ohio 15 Calls on Industry to Minimise Threat of. Cancer By ANDREW TULLY UI NEW YOIIK (UPI) -- Industry should aim at "zero exposure" of cancercausing substances to employes who deal with such material, a research fellow at the University of Cincinnati School of Medicine said Monday. While absolute "zero exposure" to such carcinogens as polyvinyl chloride and asbestos is impossible, industry should make the effort to come as close as possible to that goal of protecting em: ployes, .said Dr. Eula Bingham, a noted researcher in the occupational hazards of cancer. Vinyl chloride is used at the B.F. Goodrich plant in Avon Lake. Yesterday, Charles Arthur, of 950 Oakwood, Elyria, was released from Lorain Community Hospital where he has been treated for a rare form of liver cancer. Arthur was admitted last Thur sday and had worked at times with vinyl chloride. "It comes down to the practicality of providing us with no exposure, and that's very difficult." she said at a news conference following an address before the Conference on Occupational Car cinogenesis. The conference was spon sored by the New York Academy of Sciences at the Hotel Roosevelt. "But certainly we have to come to grips with this and...strive toward no ex posure when we deal with known car cinogens," she said. "We can't tolerate leaking valves, we can't tolerate leaking 24174010 vats." While small amounts of many car cinogens seldom are harmful to human beings, she said, other variables -- whether a worker smokes tobacco or eats foods processed with small amounts of other known carcinogens -- tend to blur the safety threshold of exposure of any industrial carcinogen. Agreeing with her "social approach" to the subject was Dr. Paul Kotin of the Jobns-Manville Corp., which deals in asbestos, but he insisted the thresholds . are no less valid, and be used the same variables sbe cited. Because a factory worker may have other carcinogens in his system, it is im possible to tell just how damaging asbestos, for instance, really is, said Kotin. "It becomes clear that...our inability to elucidate the sources of carcinogens indicates that no one can make that statement" that the safety threshold is invalid, Kotin told the conference. BFG29533
