对１８名铝作业工人和２２名对照工人的血清和尿铝测定发现，在作业环境空气中铝的时间加权几何平均浓度为０９５ｍｇ／ｍ３（０３１～４１２ｍｇ／ｍ３），铝作业工人尿铝平均水平显著高于对照工人（分别为１２２５μｇ／Ｌ和５７８μｇ／Ｌ），但血清铝水平与对照工人差异未见显著性，提示尿铝是铝作业工人较好的生物监测指标。尿单胺类神经递质代谢物测定结果表明，铝作业工人尿中的高香草酸和香草扁桃酸水平均较高，且香草扁桃酸水平显著高于对照工人。
The serum and urine aluminum measurements of 18 aluminum workers and 22 control workers found that the time-weighted geometric mean concentrations of aluminum in working ambient air were 095 mg / m3 (031 ~ 412 mg / m3), that of aluminum The average level of urine aluminum of workers was significantly higher than that of control workers (12.25μg / L and 5.78μg / L, respectively), but there was no significant difference between serum aluminum levels and control workers, suggesting that aluminum-aluminum is better for aluminum workers Biological monitoring indicators. Urine monoamine neurotransmitter metabolites measured results showed that aluminum workers in the urine of vanillic acid and vanillyl mandelic acid levels were higher, and the vanilloid mandelate levels were significantly higher than the control workers.
