摘　　要：目的了解北京两种类型迷你唱吧室内空气质量及耳机、话筒的微生物污染现况,以保障公众健康。方法对北京的商场和影院内两类迷你唱吧37间包房室内空气和74套耳机、话筒的表面物质进行微生物污染采样和测定。结果这些迷你唱吧包房室内空气质量都符合国家标准。两类包房的室内空气细菌总数无显著性统计学差异。然而,耳机和话筒表面物质的细菌和真菌检出率高,细菌的总数合格率低。其中,检出金黄色葡萄球菌,但未检出大肠埃希菌。不同结构耳机表面物质的微生物污染无显著性统计学差异。但是,不同材质话筒表面物质的细菌与真菌总数具显著性统计学差异。结论迷你唱吧的室内空气质量较好。然而,耳机和话筒存在着卫生隐患,需有关部门引起重视和防范。Objectives To find out the air quality and microbial contamination of headphones and microphones in compartments of two types of mini KTV in Beijing, and to ensure the public health of people. Methods The samples of indoor air were collected from 37 compartments in shops and cinemas, along with 74 surface substancs of headphones and microphones, and microbial contamination of which were examined. Results The air quality of these compartments were conformed with the national standards of indoor air quality. There was no significant statistical difference of total number of bacteria between the two types of mini KTV. However, the examined rates of total number of bacteria and fungi were high and the qualification rates of total bacteria on surface substances of headphones and microphones were low. In which, Staphlococcus aureus were found on the surface substances of them, but E.Coli were not found. There were no significant statistical differences of total number of bacteria among various structures of headphones and microphones, but different kinds of material for microphones showed significant statistical differences of total number of bacteria and fungi. Conclusions The air quality in two types of mini KTV were fairly good, the surface substances of headphones and microphones showed a hygienic hidden trouble to public health and needed to pay attention and to take precaution for the relevant departments.
