本文采用世界卫生组织推荐的神经行为核心测试组合，对接触混苯（甲苯、二甲苯、苯）的２３名女工和非接触混苯的１９名女工进行了神经行为功能测试。结果显示：在苯、甲苯、二甲苯分别浓度均低于现行卫生标准的作业环境中，接触混苯女工的某些行为功能（简单反应时、手提转捷度、数字译码、视觉持留、目标追踪测试Ⅱ的测试结果均差于对照组，经检验、差异有显著性。此结果为修订作业环境苯及其同系物各自的卫生标准或制定混苯的卫生标准提供了参考依据。
In this study, 23 female workers in mixed benzene (toluene, xylene, benzene) and 19 female workers in non-contact mixed benzene were tested for neurobehavioral function using the core behavioral test set recommended by the World Health Organization. The results showed that some behavioral functions of female worker exposed to benzene mixed with benzene, toluene and xylene were lower than the current hygienic standard respectively (simple response, digital rotation, visual retention, target The results of follow-up test Ⅱ were all worse than that of the control group, and the difference was significant after the test, which provided a reference for revising the hygienic standards of benzene and its homologues in the working environment or formulating hygienic standards of mixed benzene.
