摘要
对某机械厂９５名电焊作业工人的神经行为功能测试结果表明：接触组的情绪状态、反应时间、数字广度、手提敏捷度、视觉记忆、数字译码和目标追踪－Ⅱ均发生显著变化，表明电焊烟尘对作业工人的心理情绪状态、短时记忆力、注意力、模拟学习和思维能力、视觉感知和空间位置的判别、感知运动速度、手部快速运动的准确度以及眼手协调功能都有明显影响。在各工龄段比较时，控制了年龄混杂因素，发现接触组的神经行为功能随工龄增加而没有明显改变，提示作业工人对低浓度电焊烟尘的接触可能存在一定程度的耐受作用。
Neurobehavioral core test battery (NCTB) was applied to 95 electrical welders for detecting the psychological effects due to welding dust exposure at work sites. The results showed that the scores of positive mood state, digit span, Santa-Ana manual dexterity, Benton visual retention, digit symbol and pursuit aiming tests of electrical welding were signiflcantly lower than those of controls. The latency of simple reaction time in the exposed group was longer than that of controls. No significant difference was found in testing scores between various working-age groups of the exposed workers. It is suggested that welding dust exposure might be harmful to neurobehaioral fonctions to a certain extent during the welding process.
