美国曾报导接触氯乙烯(VC)生产的工人死于肝脏血管肉瘤(24例死亡病例中有3例)。另有报导指出,动物在50ppm的VC浓度下吸入染毒一年,可得肝脏血管肉瘤。会(世界卫生组织的分会)的建议我,对接触VC及PVC(聚氯乙烯)工人得恶性肿瘤的危险性进行了流行病学调查。对1,584名接触VC/PVC生产的工人进行了观察。697名仍继续生产VC,160名在工厂的其它岗位工作,33名退休,54名死亡。此外,以前接触VC而以后离厂的有640名。
In the United States, workers who exposed vinyl chloride (VC) production have reported death from hepatic angiosarcoma (3 of 24 deaths). Another report pointed out that animals exposed to VC at a concentration of 50ppm a year, available hepatic angiosarcoma. I (WHO Branch) advised me to conduct an epidemiological survey on the risk of malignant tumors in VC and PVC (PVC) workers. 1,584 workers exposed to VC / PVC production were observed. 697 were still producing VCs, 160 were working in other positions in the factory, 33 were retired and 54 were killed. In addition, there were 640 former VCs who came from the factory.
