...when researchers from Bonn University found evidence of liver damage in 19 out of 20 PVC workers at a single plant. The bombshell really burst early this year when B.F. Goodrich Co. reported that three men who worked with VC in its Louisville, Ky., plastics plant had died of angiosarcoma of the liver since 1971. Since then doctors have identified nine more cases of the cancer in the U.S., one in Great Britain and another in Norway...
Their findings are all the more significant because angiosarcoma of the liver is so rare that it has been reported only about 100 times in medical history; a major hospital in Los Angeles found only one case in 52,000 autopsies. The discovery of a dozen closely linked cases thus constitutes a sort of mini epidemic of the disease. Since such cancers may not develop for at least 15 years after initial exposure, environmental health researchers suspect that more cases will be uncovered. Says J. William Lloyd, of the National Institute for Occupational Safety and Health (NIOSH): "I would suspect...
...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...
...vinyl chloride, a plastic substance, is dangerous. Their suspicions were further aroused recently when abnormalities were discovered in the livers of a number of workers in a B.F. Goodrich Co. chemical plant in Louisville, Ky., and it was found that four of the men had a malignancy called angiosarcoma of the liver. Last week the cancer was discovered in two more of the employees and confirmed as a contributing cause of death in an employee of a West Virginia plant. Although the action comes too late to save the workers who have already contracted the disease (six have died...
