甲苯是苯的常用替代品,其毒性虽较苯低,但对工人健康仍有其不良影响,尤以对中枢神经系统的影响为甚,故监测作业工人的甲苯进入量,在预防上有一定的实践意义。马尿酸是甲苯进入人体后的代谢产物,本文观察了甲苯职业接触者马尿酸的排泄模式,并探讨其在生物监测和环境监测上的作用。 Toluene is a common substitute for benzene. Although its toxicity is lower than that of benzene, it still has adverse effects on the health of workers, especially on the central nervous system. Therefore, it is necessary to monitor the toluene intake of workers in the prevention work Practical significance. Hippuric acid is the metabolite of toluene after entering the body. In this paper, we observed the excretion pattern of hippuric acid in toluene occupational exposure and explored its role in biological monitoring and environmental monitoring.
