摘　　要：目的探讨大型公共场所地下车库空气中一氧化碳污染状况及其影响因素,为决策提供科学依据。方法抽取某商业集中区2家大型商场地下停车库为研究对象,在车库的不同区域和时间段对空气中一氧化碳浓度进行连续监测,同时监测车库内温度、湿度等微小气候指标。以1家商场开放式地面停车场为对照,分析底下停车库一氧化碳的污染程度。结果地下停车库停车区的一氧化碳浓度无论是在平时还是周末均高于地面停车场,且均具有统计学差异(P<0.05)。地下车库出口坡道与收费处空气中一氧化碳浓度高于停车区(P<0.05)。结论地下车库一氧化碳污染现象严重,应尽快制订相关卫生标准,加强监督与管理。Objectives To investigate the pollution status of carbon monoxide（CO） in large-scale underground parking garages and its influencing factors to provide the basis for hygiene monitoring and government decision-making.Methods Two large-scale parking garages under the mall were sampled with a mall open-air parking lot as control in the study.A sequence of positions and time periods was selected to monitor the concentration of carbon monoxide in the air.Simultaneously,the microclimate indexes such as temperature,humidity,wind speed were detected.Results The CO concentrations in the underground garages were higher than those at the ground parking lot during the workdays even the weekends.There was consistently significant differences between the underground and the open-air parking place statistically（P＆lt; 0.05）.The CO concentrations in the underground garage exit ramps and toll house were significantly higher than the parking space（P＆lt; 0.05）.Conclusions CO pollution in underground garages is serious.The corresponding health standards need stipulating promptly,and monitoring and management should be strengthen.
