摘　　要：目的　探讨不同生活燃料对儿童免疫功能的影响。方法　配对选择燃煤和燃气各 41名小学生作为研究对象 ,监测不同燃料导致的室内空气污染水平、同时对研究对象进行了免疫功能 7项指标包括IgA、IgG、IgM、补体C3、血清溶菌酶和CD4 、CD8的检测。结果　燃煤家庭的室内SO2 、CO、NO2 及IP均显著高于燃气家庭 ,但两组儿童的各项免疫指标未见显著性差异。结论　南方由于住房结构尤其是通风状况 ,导致燃料所产生的室内空气污染物扩散稀释速度快 ,在室内停留时间短 ,儿童实际暴露水平低 ,因此未见明显的免疫功能损害。Objective To estimate the impact of different family fuel on the children's immune system functions.Methods Fourty primary school students whose familise used coal as fuel and fourty primary students whose family fuel was gas paired with the same sex,age,grade,average income,average living space were selected as objects.The concentrations of the indoor air pollutants such as SO\-2,NO\-2,CO and IP were monitored;the levels of immune function indexes such as IgA,IgM,IgG,complement C\-3,saliva lysozyme,CD\-4,CD\-8 and CD\-4/CD\-8 of the students were tested.Results The indoor air concentrations of SO 2,CO and IP of the families using coal were significantly higher than those families using gas( P <0.05),the concentration of NO 2 was higher in the gas families.Conclusion Because of the good ventilation condition,the diffusion and dilution of the indoor air pollutants were very quickly and there was no significant difference in the immune function indexes between the two groups( P >0.05).
