石油液化气作业工人神经行为功能的调查

Effect of Liquefied Petroleum Gas on Neurobehavioral Function of Workers

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 5 0名作业工人 (接触组 )进行了测定 ,并与 5 0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 ,差别有显著性 (F =4 32 ,5 0 1,P <0 0 5 ) ;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 5 2 ,P <0 0 5 )。

To study the effects of iiquefied petroleum gas on neurobehavioral 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.
