聚氯乙烯树脂在合成过程中逸出的氯乙烯单体对人体有毒性。为了解长期接触氯乙烯对妇女生殖功能的影响,我们统计自1981～1985年全厂女工妊娠401次,出生333人次,自然流产率为16.9％,氯乙烯作业女工第一胎妊娠43人,其中12人患妊娠高血压综合征,发病率达27.9％,明显高于非接触氯乙烯女工(16.3％)及一般人群(2％～15％),且重度患者比例较大。结合1985年前车间空气氯乙烯浓度明显 Polyvinyl chloride resin during the synthesis of vinyl chloride monomer is toxic to humans. To understand the long-term exposure to vinyl chloride on the reproductive function of women, we statistics from 1981 to 1985 the whole factory women 401 pregnancies, births 333 people, the spontaneous abortion rate was 16.9%, vinyl chloride female workers first pregnancy 43, of which 12 cases of pregnancy-induced hypertension syndrome, the incidence rate of 27.9%, significantly higher than non-contact PVC female workers (16.3%) and the general population (2% to 15%), and a greater proportion of severe patients. The combination of 1985 workshop before the air concentration of vinyl chloride obvious
