聚氯乙烯生产过程中对人体有危害的物质主要是氯乙烯与氯化汞。有关氯化汞对人体的危害已比较清楚。氯乙烯单体以往认为它对人体威胁不大。近几年来,国内外报导,聚氯乙烯制造工,特别是聚合工序工人的肝肿大比例明显高于对照组,部分有肝功能异常。国外资料报导,长期接触氯乙烯的生产工人,可发生指端动脉痉挛,指端溶骨症,硬皮病,肝血管肉 Polyvinyl chloride in the production process is harmful to human beings mainly vinyl chloride and mercuric chloride. The harm of mercuric chloride to human beings is clearer. Vinyl chloride monomer in the past that it is not a threat to the human body. In recent years, domestic and foreign reports, PVC manufacturing workers, especially the proportion of workers in the polymerization process hepatomegaly significantly higher than the control group, some with abnormal liver function. Foreign data reported that long-term exposure to the production of vinyl chloride workers may occur finger artery spasm, finger osteolytic disease, scleroderma, hepatic vascular meat
