...chloroprene (the base for several synthetic rubber products) have higher rates of skin and lung cancer than the rest of the population. Vinyl chloride, a colorless gas that is the basic ingredient of the widely used plastic poly vinyl chloride (PVC), has been identified as a cause of angiosarcoma of the liver. Until recently, this cancer was so rare that one Los Angeles hospital found only one case in 52,000 autopsies. Since last year, however, doctors have confirmed 19 cases of the cancer in the U.S. alone, 17 of them in people who worked in plastics plants. There...
...Goodrich Co., it has been linked to disease. First it was shown to be dangerous to laboratory rats and mice. Later it was implicated in a variety of human ills: hepatitis, a crippling bone disease, and cancer. This year B.F. Goodrich reported that three workers had developed angiosarcoma of the liver, an extremely rare and invariably fatal form of cancer (TIME, May 13). Since 1961, 16 deaths of angiosarcoma among vc workers have been uncovered in the U.S., and another ten in Europe -conclusive evidence of the danger...
...final ruling was a compromise. Nonetheless, Dow Chemical Co. was quick to describe the new limit as "unnecessarily stringent." Having dealt with vc for nearly 25 years and cut exposure levels to 50 p.p.m. back in 1961, the company reported no cases of angiosarcoma; its evidence thus indicated that amount as a safe level of exposure. Moreover, the industry says that it simply does not have the technology to comply with the new restriction, and the Society of the Plastics Industry has sued to overturn OSHA's ruling...
...that more than 200 million Ibs. of vc and 50 million Ibs. of PVC are being discharged into the environment during the conversion process. In other words, people who live downwind of factories that make PVC might also unknowingly be getting a whiff of the gas. Two cases of angiosarcoma have in fact been reported in people whose houses were near a PVC plant in Bridgeport, Conn...
...Safety and Health Administration has issued emergency regulations reducing allowable VC levels to 50 parts per million. Whether this is adequate to provide long-term protection for plastics workers remains to be seen. An industry-sponsored study has shown that when mice are exposed to those levels, they develop angiosarcoma...
