为探讨长期接触低浓度甲苯对神经内分泌系统的影响,作者对两所印刷厂的47名工人,(年龄23～62岁,平均44.4岁)进行了研究。其中 A 厂28人,接触甲苯工龄4～33年,平均18.4年;工作区空气中甲苯浓度3.3～356.4 mg/m~3,平均36.3 mg/m~3。B 厂19人,接触甲苯工龄3～39年,平均14.5年;工作区甲苯浓度19.8～468.6 mg/m~3,平均155.1 mg/m~3。接触 To investigate the effects of long-term exposure to low levels of toluene on the neuroendocrine system, the authors studied 47 workers (aged 23-62, mean 44.4 years) in two printers. Among them, 28 workers in Factory A and 4 to 33 years old worked in toluene for an average of 18.4 years. The concentration of toluene in the air in the work area ranged from 3.3 to 356.4 mg / m 3, with an average of 36.3 mg / m 3. B plant 19 people, contact with toluene length of 3 to 39 years, an average of 14.5 years; work area toluene concentration 19.8 ~ 468.6 mg / m ~ 3, an average of 155.1 mg / m ~ contact
