石油液化气作业工人神经行为功能的调查

为探讨石油液化气生产作业对工人神经行为功能的影响,采用WHO推荐的神经行为功能测试方法对50名作业工人(接触组)进行了测定,并与50名非职业性有害因素作业的工人(对照组)进行了比较.结果显示:接触组工人情感状态问卷的疲惫-惰性的分数高于对照组,有力-好动的分数低于对照组,差别有显着性(F=4.32,5.01,P<0.05);接触组的手提转捷度(利手)、数字译码、目标追踪的正确打点数和总打点数低于对照组(F=4.19～5.52,P<0.05).提示石油液化气生产作业可引起工人神经行为功能的改变.

Effect of Liquefied Petroleum Gas on Neurobehavioral Function of Workers

To study the effects of iiquefied petroleum gas on neurobe-havioral functions of workers,50 workers exposured to liquefied petroleum gas were investigated with WHO recommended neurobehavioral core test battery,and compared with 50 nonexposured controls.Results show:fatigue-inertia scores in profile of mode states of workers exposured to liquefied petroleum gas was signiffcantly higher and vigor-activity score was significantly lower than those of controls(F=4.32,5.01,p<0.05).Santa anna manual dexterity test,digit symbal and correct aiming,all aiming of pursuit aiming in workers exposured to liquefied pet roleum gas were significantly lower than those of controns(F=4.19～5.52,p<0.05).Conclusion:changes of neurobehavioral functions could be caused by liquefied petroleum gas.
