目的探索铝的神经毒性和职业性铝作业工人神经行为功能的年龄依赖性差异。方法采用ＷＨＯ推荐的神经行为测试组合（ＮＣＴＢ）对１０３名铝作业工人和６４名对照工人进行了神经行为功能测试，同时测定车间空气中铝的浓度和铝作业工人每天铝吸入量及尿铝水平。结果中老年铝作业工人的紧张焦虑、忧郁沮丧和愤怒敌意情绪明显强于同年龄对照组工人；青年铝作业工人的数字跨度得分、中年铝作业工人的数字译码得分和中老年铝作业工人的目标追踪打点数均明显低于同年龄对照组工人。结论职业性铝接触可影响工人正常的神经行为功能，而且存在年龄依赖性差异。年青工人主要表现为记忆力衰退，中老年工人主要表现为情感状态的变化及运动速度和精确度下降
Objective To explore the age-dependent differences in the neurotoxicity of aluminum and the neurobehavioral function of occupational aluminum workers. Methods The neurobehavioral test was performed on 103 aluminum working workers and 64 control workers using the NCTB recommended by the WHO. The aluminum concentration in the air of the workshop and the daily aluminum intake and aluminum-aluminum level of aluminum workers . Results The stress-anxiety, melancholy-depression and anger-hostility of middle-aged and elderly aluminum workers were significantly higher than those of the same-age control group. The numerical span of young aluminum workers, the middle-aged aluminum workers’ The number of target workers for aluminum workers was significantly lower than that of workers of the same age group. Conclusion Occupational exposure to aluminum can affect the normal neurobehavioral function of workers, and there are age-dependent differences. Young workers are mainly manifested as memory decline, middle-aged and older workers mainly as a result of changes in emotional status and movement speed and accuracy decline
