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。
The results of neurobehavioral tests on 95 welders in a mechanical factory showed that the emotional state, response time, digit breadth, hand-held agility, visual memory, digital decoding and target tracking-Ⅱ of the exposure group all changed significantly Welding dust has obvious effects on workers’ mental and emotional state, short-term memory, attention, simulated learning and thinking ability, visual perception and spatial location discrimination, perceived movement speed, accuracy of hand rapid movement and eye hand coordination influences. When comparing the different age groups, we controlled the age mixed factors and found that the neurobehavioral function of the exposed group did not change significantly with the increase of the seniority. It suggested that the workers may have a certain degree of tolerance to the low concentration of the welding fume.
