Neuropsychiatric symptoms in 65 welders exposed to aluminium and 217 railroad track welders were studied with the aid of a previously validated questionnaire. Semiquantitative data on exposure to the metals aluminium, chromium, lead, manganese, and nickel were also recorded by questionnaire. Logistic regression was employed to study the relation between exposure and the prevalence of symptoms. Welders exposed to aluminium, lead, or manganese for a long period had significantly more neuropsychiatric symptoms than welders not exposed to these metals. The results indicate that detailed psychometric studies should be performed on welders exposed long term to specific metals as such exposures might affect their nervous system.
借助一份先前经验证有效的问卷,对65名接触铝的焊工和217名铁轨焊工的神经精神症状进行了研究。还通过问卷记录了有关铝、铬、铅、锰和镍等金属接触情况的半定量数据。采用逻辑回归研究接触与症状患病率之间的关系。长期接触铝、铅或锰的焊工比未接触这些金属的焊工有明显更多的神经精神症状。结果表明,对于长期接触特定金属的焊工应进行详细的心理测量研究,因为这种接触可能会影响他们的神经系统。
