铝厂不同作业环境对工人免疫功能及微量元素的影响

目的 探讨铝厂不同作业环境对工人免疫功能及微量元素含量的影响。方法 对某铝厂的铸造、净化、电解和计控（对照）车间男性作业工人各２４名进行免疫功能及微量元素含量检测。结果 铸造（接铝组）和净化车间工人（接铝＋氟组）血清ＩｇＡ含量升高,ＩｇＭ含量和淋巴细胞计数降低,电解车间工人（接铝＋氟＋磁场组）血清ＩｇＡ、ＩｇＧ含量和淋巴细胞计数升高,该３组工人全血侣、铁、锰、铜、镁含量和尿氟有不同升高。结论 接触

Effects of different working environment on immune function and trace elements of employees in an aluminum refinery

Objective To study the effects of different working environment on immune function and trace elements in employees of an aluminum refinery.Methods Immune function and whole blood trace elements were determined for 24 employees working in the workshops of foundry(exposed to aluminum),purification(exposed to aluminum and fluoride),electrolysis(exposed to aluminum,fluoride and magnetic field)and computer control room(control group) each in an aluminum refinery.Results Serum content of immunoglobulin A(IgA)increased and that of immunoglobulin M(IgM)and lymphocyte count decreased in the workers of foundry and purification workshops.Serum levels of IgA and IgG and lymphocyte count increased in the workers of electrolysis workshop.Whole blood levels of aluminum,iron,manganese,copper and magnesium and urine level of fluoride all increased to varied extent in the workers of these three groups.Conclusion Exposure to lowlevel aluminum and fluoride could cause increase in IgA,decrease in IgM and lymphocyte count,and increase in blood aluminum load and excretion of urine fluoride.Exposure to magnetic field could cause increase in IgG and lymphocyte count.Exposure to aluminum,fluoride and magnetic field in a stable status could cause changes in whole blood levels of iron,manganese,copper and magnesium,et al.
