对长春市冬季不同采暖方式的居室ＣＯ污染状况作了调查，并对居住的孕妇血中ＣＯＨｂ、唾液溶菌酶和唾液ＳＩｇＡ含量作了检测。结果表明：燃煤组居室空气ＣＯ浓度显著高于暖气组；其孕妇血中ＣＯＨｂ含量也明显高于暖气组，而唾液溶菌酶和ＳＩｇＡ含量较暖气组明显降低。对同组的孕妇与丈夫各项指标进行比较，结果发现燃煤组孕妇唾液溶菌酶和ＳＩｇＡ明显低于同组丈夫，表明孕妇作为敏感人群，其健康更易受到危害
This paper investigated the CO pollution in the living room in different heating methods in winter in Changchun city and detected the content of COHb, salivary lysozyme and salivary SIgA in pregnant women. The results showed that CO concentration in room air of coal-fired group was significantly higher than that of heating group. COHb content in blood of pregnant women was also significantly higher than that of heating group, while salivary lysozyme and SIgA levels were significantly lower than those of heating group. Comparison of the indicators of pregnant women and husband in the same group showed that the saliva lysozyme and SIgA of pregnant women in the coal-fired group were significantly lower than those of the same husband, indicating that their health as a sensitive group is more susceptible to harm
