高温对工人神经行为功能的影响

本文对某发电厂高温作业工人神经行为功能进行了测试。结果表明，与对照组相比工龄１年以上的受试者视简单反应时、听简单反应时、视选择反应时和听选择反应时明显延长，数字跟踪、数字记忆和行为指数明显低于对照组。工前与工中比较，视简单反应时、听简单反应时、视选择反应时、听选择反应时、动作反应时和指叩测验等差异有显著性意义。工中反应时明显延长，反应时减少，且选择反应时明显长于简单反应时，提示高温明显降低作业工人

Liu Kejian, et al. Studies on the effectof neurobehavioral function of workers expo-sed to high temperature in a power plant

A neurobehavlor functlonaI test was con-ducted for workers exposed to high tempera-ture in a power plant.The results showed thatas cornpared :with the control group, visualsimple reaction time(VSRT).Auditory simplereaction time(ASRT)and auditory choicercaction time(ACRT)appeared to be slgnifi-cantly prolonged for workers whose lengths ofservice were above one year,and digit tracing(DT).Digit memory(DM)and behavior in-dex(BI) significantly decrased.VSRT,ASRT,VCRT,ACRT,acting reaction time(ART)and finger tapping (FT)during work showedstatistically significant differences in contrastto those before work.The reaction time du-ring work were obviously lengthened and Rtreduced. Choice reaction times were muchlenger than simple ones.These findings sugges-ted that hihb temperature might be able todecrease neurobehavioral function of workersand SG-A behavioral function test devicemight be a good tool for studying the changeof the neurobehavioral function in high tem-perature environment.
