对某工路段89名养路工的神经行为功能测试结果表明,接触组的数字广度、手提敏捷度、数字译码、视觉记忆和目标追踪-Ⅱ得分均显著低于对照组,视觉运动反应时显著长于对照组。接触组的愤怒情绪状态和数字译码得分随工龄增加显著降低,而平均反应时随工龄增加明显延长。提示沥青对养路工神经行为功能的影响可能存在一定的剂量—效应关系。
The neurobehavioral test results of 89 road maintenance workers at certain construction sites showed that the digital breadth, mobile agility, digital decoding, visual memory and target tracking-Ⅱ scores of the contact group were significantly lower than those of the control group, and visual motor response was significant Longer than the control group. The scores of angry emotions and digital decoding in the contact group decreased significantly with the increase of seniority, while the average response time increased significantly with the increase of seniority. Suggesting that asphalt may have some dose-effect relationship to the neurobehavioral function of road maintenance workers.
