以甲苯原形物在尿中排泄量来评价暴露水平的文献报道甚少。本文旨在探讨甲苯在尿中的排泄规律,以便为合理安排工人作息时间及不同时点采样监测的运用提供依据。 1 材料与方法健康志愿者6人,其中女2人。跟班作业6小时,收集其停止暴露后0,2,4,16小时的尿液。用气相色谱仪检测尿中甲苯浓度,以比重1.020进行校正。 2 结果与讨论 6名志愿者在停止暴露后的0,2,4,16小时尿中甲苯浓度(X±
There are few reports on the level of exposure of toluene prototype in urine. This paper aims to explore the excretion of toluene in the urine in order to reasonably arrange for workers to schedule work and sampling at different times to provide the basis for the use of monitoring. 1 Materials and Methods 6 healthy volunteers, of whom 2 were female. Follow-up homework 6 hours, collecting 0,2,4,16 hours after its termination of urine exposure. The concentration of toluene in the urine was measured by gas chromatography and corrected with a specific gravity of 1.020. 2 Results and Discussion Toluene concentration in urine of 6 volunteers at 0, 2, 4, and 16 hours after cessation of exposure (X ±
