本文用现场暴露方法，观察了在电解铝车间环境，氟（０２ｍｇ／ｍ３）、铝（２６３ｍｇ／ｍ３）和强稳定磁场（１００ＧＳ）联合作用下对小鼠免疫功能的影响。结果显示，与对照组比较，暴露５天组、１０天组和１５天组小鼠胸腺、脾、心、肺、肝、肾、脑和股骨的脏器系数均无明显差异。反映小鼠体液免疫功能的抗体形成细胞数（ＰＦＣ）和半数溶血值（ＨＣ５０），暴露５天组和１０天组均比对照组明显升高（Ｐ＜００１或Ｐ＜００５），而反映淋巴细胞增殖功能的ＭＴＴ试验，各暴露组的吸光度差值均比对照组明显增加（Ｐ＜００１）。提示：暴露于较低浓度氟、铝和强磁场联合环境中，对小鼠的体液免疫功能和淋巴细胞增殖功能有促进作用，而对胸腺、脾等脏器重量无明显影响 In this paper, the effects of the combination of fluorine (0.2 mg / m3), aluminum (2.63 mg / m3) and strong magnetic field (100 GS) on the immune function of mice in an aluminum plant were observed by field exposure method. The results showed that compared with the control group, there was no significant difference in the organ coefficients of thymus, spleen, heart, lung, liver, kidney, brain and femur between the 5th day, the 10th day and the 15th day. The number of antibody-forming cells (PFC) and half-value hemolytic value (HC50), which reflected humoral immune function in mice, were significantly increased (P <001 or P <005) , While MTT assay, which reflects the proliferation of lymphocytes, showed a significant difference in absorbance between the exposed groups and the control group (P <001). Hint: Exposure to low concentrations of fluoride, aluminum and strong magnetic field combined environment, promote humoral immune function and lymphocyte proliferation in mice, but had no significant effect on the weight of organs such as thymus and spleen
