对１１５名职业性暴露于铝尘的磷化铝生产工人和４２名对照工人进行神经精神病学症状调查。发现暴露组具有３种以上神经精神病学症状的比率为３３．０％，ＯＲ＝３．６５（９５％ＣＩ＝１．２８～１０．４３），症状有随着暴露年数的递增而升高的趋势，其脑电图异常及界限性脑电图改变率高达５２．６％。提示对职业性铝尘暴露工人进行神经精神病学症状调查是早期发现中枢神经系统损害重点观察对象的有效方法。
Neuropsychiatric symptom surveys were conducted on 115 aluminum phosphide producers exposed to aluminum dust and 42 control workers. The prevalence of neuropsychiatric symptoms in the exposed group was found to be 33.0% (OR = 3.65, 95% CI = 1.28 to 10.43). The symptoms increased with years of exposure Trend, EEG abnormality and borderline EEG change rate as high as 52.6%. It is suggested that the investigation of neuropsychiatric symptoms in workers exposed to occupational aluminum dust is an effective method for early detection of key observation subjects of central nervous system damage.
