近来美国报导了15名氯乙烯工人死亡,引起人们的注意。乃提出聚氯乙烯产品是否可致肝肿瘤(血管肉瘤)或其他肿瘤的问题。现在聚氯乙烯产品几乎在每个家庭、机关、工厂都有,用作管道、地板、家具覆面等。为此,美国国家环境卫生科学研究所召集了一个讨论会。与会者指出氯乙烯是化学工人接触的许多高毒物质中仅有的可能致肿瘤物质。这个聚合物在分解和破坏时的化学、物理作用以及聚合物的分解物的相互作用正被逐渐了解。氯乙烯单体进入机体,被一种不明的酶分解为一氯乙烯氧化物。氯乙烯分子在 Recently, the United States reported the death of 15 vinyl chloride workers and attracted people’s attention. Is to raise the question whether PVC products can cause liver tumors (angiosarcomas) or other tumors. Now PVC products almost every family, agencies, factories have, for pipes, floors, furniture, etc.. To this end, the United States National Institute of Environmental Health convened a seminar. Participants noted that vinyl chloride is the only possible tumor causing substance in many highly toxic substances that chemical workers come into contact with. The chemical, physical effects of this polymer upon decomposition and destruction, as well as the interaction of the polymer’s decomposition products, are being understood. Vinyl chloride monomer into the body, was an unknown enzyme is broken down into monochloroethylene oxide. Vinyl chloride molecules in the
