摘　　要：[目的]调查坑道空气真菌污染的形成,探讨其对人体健康的不利影响,为特殊情况下进驻坑道采取预防措施提供科学依据。[方法]用撞击法检测坑道空气真菌数,同时检测微小气候。根据真菌菌落形态特征及生长结构进行菌种鉴定。[结果]通道和房间的真菌数分别为5985cfu/m3及9548cfu/m3,与对照组比较差异均有统计学意义(P﹤0.01),且房间明显高于通道(P﹤0.01)。[结论]坑道空气真菌污染严重,长期暴露于严重污染空气中,将对人体健康造成不利影响,这些真菌能侵入机体造成真菌感染,以呼吸系统病变和变态反应为主,应给予足够重视。[ Objective ] To provide scientific basis for adopting correct precaution in special situation by researching the generation of mycetes contamination in the air in tunnel and its hazard to human health. [ Methods ] The mycetes in the air in tunnel were counted with the method of knock-on and were identified according to their colonial morphology and construction. The microclimate in tunnel was detected too. [Results] The mycetes in corridors and rooms were 5 985 cfu/m^3 and 9 548 cfu/ m^3 respectively, which were higher than those in the control group （P〈 0.0l） . And there were more mycetes in rooms than in corridors （P〈 0.01） . [Conclusions] The air contamination of mycetes in tunnel is serious and it is harmful to humans who expose to the air for a long time. The mycetes may cause mycetes infection which is mainly characterized by respiratory system pathological changes and allergies, which we should take seriously.
