用回顾性队列研究方法,观察16年期间,接触丙烯腈(CH_2=CHCN)、丙烯酸甲酯(CH_2=CECO_2CH_3)、硫氰酸钠(CNNaS)毒物工人的死亡情况。结果发现,该厂男性工人脑血管病死亡人数与当地居民比明显超额,差别有统计学意义。恶性肿瘤死亡人数随工龄增加而上升,平均死亡年龄比常人提前10年～15年。开展这项研究工作,可为卫生标准制定及环境卫生学评价提供科学依据。
A retrospective cohort study was conducted to observe the deaths of workers exposed to acrylonitrile (CH_2 = CHCN), methyl acrylate (CH_2 = CECO_2CH_3) and sodium thiocyanate (CNNaS) during 16 years. The result showed that the death rate of cerebrovascular disease of male workers in this plant was significantly larger than that of local residents, the difference was statistically significant. The number of deaths from malignancies increased with the increase of seniority. The average age of death was 10 years to 15 years earlier than normal. Carrying out this research can provide a scientific basis for the development of health standards and the evaluation of environmental hygiene.
