本文对某聚氯乙烯树脂厂氯乙烯接触者４０５名工人（男３１９名，女８６名）和不接触任何毒物的某建筑部门４１１名工人（男３４２名，女６９名）对照组，进行了恶性肿瘤发病情况的对比研究。结果表明，作业环境空气中氯乙烯浓度为０．５～５６９６．６ｍｇ／ｍ３，男性接触氯乙烯者恶性肿瘤和肝癌死亡率分别为１５４．３１／１０万和６８．５６／１０万，略高于对照组，未见显著性差异；全肿瘤、肝癌死亡年龄比对照组显著提前；接触组发现１例肝血管肉瘤。
This article conducted a control group of 405 workers (male 319, female 86) who contacted vinyl chloride resin plant vinyl chloride and 411 workers (men 342, women 69) who did not contact any poisons in a construction department. Comparative study of the incidence of malignant tumors. The results showed that the concentration of vinyl chloride in the air in the working environment was 0.5-5696.6 mg/m3, and the death rate of malignant tumors and liver cancer among men exposed to vinyl chloride was 154.31/100,000 and 68.56/100,000 respectively. In the control group, no significant difference was found; the death age of the whole tumor and liver cancer was significantly earlier than that of the control group; one case of hemangiosarcoma was found in the contact group.
