【摘要】 为了解北京大学园区室内空气质量，对园区不同类型房屋内ＣＯ、ＣＯ２与ＮＭＨＣ（非甲烷烃）浓度进行测定。结果表明ＣＯ与ＣＯ２的浓度随季节有明显的变化〔ＣＯ：０．１～３２．１ｍｇ／ｍ３，２．７±０．９ｍｇ／ｍ３；ＣＯ２：０．０２７％～０．５２８％（０．０８４±０．０３１）％〕。燃料燃烧是住宅室内ＣＯ与ＣＯ２的主要来源，人的活动是公共场所ＣＯ２的重要来源，学生宿舍的ＣＯ与ＣＯ２主要来源于室外。室内ＮＭＨＣ的浓度（０．６０～１３．０４ｍｇ／ｍ３）受到室外环境、室内装修材料以及办公设备的使用等因素影响更多还原

【Abstract】 To explore the indoor air quality of Peking university,the concentrations of carbon monoxide(CO),carbon dioxide(CO 2) and non methane hydrocarbons (NMHC) in the indoor air were measured in different types of rooms of Peking university.The results showed that the concentrations of CO(0.1￣32.1 mg/m 3) and CO 2 0.027%￣0.528%(0 084±0 031)% presented obvious variation with the seasons CO and CO 2 in the living rooms and student dormitaries mainly came from fuel combustion and outdoor air respectively.CO 2 in the public houses mainly resulted from human activities.The levels of NMHC (0.60￣13.04 mg/m 3) were affected by these factors,such as outdoor environment,indoor decorative meterials and the running of the office equipment etc.更多还原
