作者对职业性接触甲苯,浓度为30～180ppm的52名工人,以不接触甲苯101名工人及虽接触甲苯但在研究期间无接触甲苯82名工人,二组作为对照组进行尿中马尿酸的分析。同时约每隔一小时测试作业环境的甲苯浓度。以肺通气量0.75立方米/小时,甲苯在肺内贮留量初二小时为72％,以后为57％来计算甲苯的吸入量。 The author of occupational exposure to toluene, the concentration of 30 ~ 180ppm of 52 workers to non-contact with toluene 101 workers and although the exposure to toluene but in the study without contact with toluene 82 workers, the two groups as a control group urinary hippuric acid analysis. Also test the toluene concentration of the working environment about every hour and hour. To pulmonary ventilation 0.75 cubic meters / hour, toluene in the first two hours of storage in the lungs was 72%, 57% to calculate the amount of toluene inhaled.
