为了解电解铝作业环境对工人神经系统功能及微量元素代谢的影响， 对某电解铝厂的４８ 名作业工人及２４ 名对照工人进行了神经系统检查和生物样品检测。结果发现与对照组比较，电解铝作业工人血清胆碱酯酶（ＡｃｈＥ） 活性明显升高， 尿香草扁桃酸（ＶＭＡ） 含量明显升高， 全血微量元素铝、铁、铜、锰、镁含量明显升高和尿氟升高。这些结果表明： 接触低浓度铝、氟和稳态磁场的工人神经系统影响以生化代谢改变为主，表现为ＡｃｈＥ活性和尿ＶＭＡ 含量升高，机体铝负荷增高及铁、铜、锰、镁微量元素重新分布。
In order to understand the impact of the working environment of aluminum on workers’ nervous system function and the metabolism of trace elements, neurological examination and biological sample testing were performed on 48 workers and 24 control workers in an electrolytic aluminum plant. The results showed that, compared with the control group, the activity of serum cholinesterase (AchE) in workers exposed to aluminum was significantly increased, the content of urinary vanillin mandelic acid (VMA) was significantly increased, and the levels of trace elements aluminum, iron, copper, manganese and magnesium Significantly increased urinary fluoride and increased. These results indicate that the changes of nervous system in workers exposed to low concentrations of aluminum, fluorine and steady-state magnetic fields are dominated by biochemical metabolic changes, showing increased AchE activity and urinary VMA content, increased aluminum load and trace amounts of iron, copper, manganese and magnesium Elements redistribution.
