甲苯作业对工人神经行为功能的影响

Effect of toluene on worker's neurobehavioral function

对接触甲苯工人(暴露组)和对照组工人采用神经行为核心测试组合(NCTB)进行神经行为测试。结果暴露组在目标追踪、数字译码、数字跨度及视觉记忆测试等方面与对照组相比差异有显著性(P<0.05)。说明接触甲苯对作业工人的神经行为功能可产生一定的影响。

Seventy-two workers exposed to toluene were selected as the exposure group, 55 workers without exposure to any toxic chemicals were selected as the control group. The neurobehavioral functions were examined with neurobehavioral core test battery （NCTB）. The results showed that there all were significant differences between exposure group and control group in pursuit aiming test, digit symbol test, digit span test and Benton visual retention test （ P 〈 0.05）. It is suggested that occupational exposure to toluene might affect neurobehavioral function of workers.
