作者对258名接触苯作业(油漆、刷漆、喷漆)工人的尿酚排出量进行观察、试图对尿酚排出量作为苯工人接触的指标初步探讨。尿酚测定为对硝基苯胺法,尿比重系根据Walkley.J.E.Pagnatto等氏提出的“改进测定尿酚的方法”,结合薛寿征氏介绍的计算方法,将尿比重调至1.024。尿液系在工人每日8~12时上班后4小时取一次尿样。
The author of 258 workers exposed to benzene (paint, paint, paint) workers observed the amount of urinary phenol emissions, trying to urinary phenol emissions as benzene workers exposure to a preliminary study. Determination of urinary phenol as p-nitroaniline method, urine specific gravity according to Walkley.J.E.Pagnatto et al proposed “method for the determination of urinary phenol”, combined with Xue Shouzheng’s calculation method introduced, the urine specific gravity adjusted to 1.024. Urine in the workers daily 8 to 12 hours after work 4 hours to take a urine sample.
