作者报道了美国俄亥俄州阿克隆市一间橡胶制造厂的丙烯腈聚合车间工人和处理聚合丙烯腈车间的工人的死亡率。研究对象是1940年1月1日～1971年1月1日期间工龄两年以上的男性白人生产工人,一共327人,包括了这两个车间的全部工人。丙烯腈聚合车间制造腈橡胶。1938～1949年间,该车间用丁二烯和苯乙烯为原料,1949年以后改用乙烯吡啶。腈橡胶制造先是在密闭的管道中生产胶乳,然后除去过量单体,将胶乳喷入下边的槽中。在这个过程中工人接触丙烯腈最多。处理聚合丙烯腈车间是 The authors report on the mortality of acrylonitrile polymerization shop workers and workers in polymerized acrylonitrile workshops at a rubber plant in Akron, Ohio, USA. The study was conducted on January 1, 1940 to January 1, 1971, male Caucasian white-collar workers of more than two years of work experience, a total of 327 people, including all the workers in both workshops. Acrylonitrile polymerization plant manufacturing nitrile rubber. 1938 to 1949, the workshop with butadiene and styrene as raw materials, after 1949 to vinyl pyridine. Nitrile rubber is made by first producing latex in a closed tube, then removing excess monomer and spraying the latex into the lower tank. The worker touches most acrylonitrile during this process.
