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 2 4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组工人全血铝、铁、锰、铜、镁含量和尿氟有不同升高。结论 接触低浓度铝、氟主要引起IgA升高 ,IgM含量和淋巴细胞计数下降 ,血铝负荷升高和尿氟排出增加。接触磁场引起IgG和淋巴细胞计数升高。接触铝、氟、稳态磁场均会引起全血铁、锰、铜、镁等微量元素的改变
Objective To investigate the effects of different operating environments in aluminum plant on the immune function and the content of trace elements in workers. Methods A total of 24 male workers in the foundry, purification, electrolysis and control (control) workshops of an aluminum plant were respectively tested for immune function and trace element levels. Results The levels of serum IgA, IgM and lymphocyte counts in casting (receiving aluminum group) and cleaning workshop workers (receiving aluminum + fluoride group) were decreased. The levels of IgA and IgG in serum of electrolytic workshop workers Lymphocyte count increased, the three groups of workers with varying levels of blood aluminum, iron, manganese, copper, magnesium and urine fluoride increased. Conclusion Exposure to low concentrations of aluminum and fluoride mainly results in the increase of IgA, the decrease of IgM and lymphocyte counts, the increase of blood aluminum load and the increase of urinary fluoride excretion. Contact with the magnetic field causes elevated IgG and lymphocyte counts. Contact with aluminum, fluorine, steady-state magnetic field will cause changes in the blood of iron, manganese, copper, magnesium and other trace elements
