日本三木知子等以爱知县的某聚氨酯树脂工厂的汽车零件制造作业者为对象,从1979年到1983年经过5年的时间,定期测定评价车间环境空气的TDI的浓度,同时对43名男性作业者进行了以肺功检查为主的健康调查。此外,根据接触的形式和时间,将其分为直接接触组(19名、A组),间接接触组(每日只从事3～4小时的间接接触,24名,B组)。 43名成人男性作业者的平均年龄为35.3±9.7岁(A组:36.1±11.5岁,B组:34.7±8.3岁),工龄为10.5±3.6年(A组:10.8±2.6年,B组:10.3±4.3年),A、B两组没有显著差异,且都没有包含粉尘作业的特定的有害作业既往史,没有遗传病史,其他病既往史中只有陈旧性肺结核,高血
Japan’s Mochizuki and others targeted a manufacturer of automotive parts at a polyurethane resin plant in Aichi prefecture. From 1979 to 1983, TDI concentrations in the ambient air of the workshop were measured and evaluated regularly over a period of five years. At the same time, 43 male workers Who conducted a pulmonary function test-based health survey. In addition, according to the form and time of exposure, they were divided into direct contact group (group A, 19), indirect contact group (indirect contact for 3-4 hours only, 24, group B). The mean age of 43 adult male workers was 35.3 ± 9.7 years (group A: 36.1 ± 11.5 years, group B: 34.7 ± 8.3 years) and the length of service was 10.5 ± 3.6 years (group A: 10.8 ± 2.6 years, group B: 10.3 ± 4.3 years). There was no significant difference between groups A and B, and none of them contained the past history of specific hazardous jobs with dust and no genetic medical history. In the past history of other diseases, only old tuberculosis and high blood
