摘要
采取新旧地铁站台对比研究的方法选取三个有代表性的换乘站的六个站台,分别研究各站台空气中细菌、真菌的含量,并做浅要分析。结果表明:旧站台在细菌数上远比新站台高,而真菌数却明显比新站台低(一号线东单站站台例外)。菌落总数只有2号线复兴门站站台超过2500 cfu/m3,达2883 cfu/m3;再则是1号线复兴门站站台接近2500 cfu/m3,为2092 cfu/m3,其余诸站台均明显低于2500 cfu/m3。这表明北京市地铁站站台空气微生物的质量比较好。对菌种进行初步分析知细菌的优势菌种为球菌(金黄色葡萄球菌、双球菌)和杆菌,真菌的优势菌种为青霉属和黄曲霉属。
Through compared the new and old subway platforms and selected six platforms in three representative interchange stations, the contents of bacterium and fungal are studied and briefly analyzed. The results show that the bacterial population of old platforms is more than bacterial population of new platforms, but fungal is adverse situation. The microbial quality of subway platform of Beijing city is better, and through preliminary analysis of strains, it is known that the dominant strains of bacterium are coccus and bacillus, and the dominant strains of fungus are peniciUium and aspergillus.
