摘  要:[目的]了解宝山区新装修住房室内空气甲醛污染现状,为控制室内空气污染提供科学依据。[方法]于2008年4月至2009年12月调查宝山区内20户新装修(不超过6个月)的住宅,检测室内空气中的甲醛浓度。[结果]甲醛超标较为严重,住宅室内甲醛质量浓度为0.001 8~1.90mg/m^3,户合格率仅40%。多因素logistic分析结果显示自然通风时间、检测时的温度及是否有家具对甲醛浓度的影响具有统计学意义(P<0.05),自然通风时间与甲醛浓度呈负相关,检测时高气温(≥25℃)与甲醛浓度呈正相关,室内放置家具会使室内甲醛浓度上升。[结论]部分新装修住宅室内空气甲醛污染状况不容忽视,装修后注意充分通风换气有利于降低室内甲醛浓度。[ Objective ] To understand indoor air pollution situation in recent decorated residential apartments in Baoshan District and to provide scientific evidences for the control of indoor formaldehyde pollution. [ Methods ] Twenty recent decorated residential apartments were selected to monitor indoor formaldehyde from April 2008 to December 2009. The data were analyzed with SPSS11.0. [ Results ] The indoor pollution of formaldehyde was significant and only 40% of the 20 apartments met the nationalof formaldehyde. The result of muhinomial logistic analysis indicated that natural ventilation duration, air temperature and furniture layout were significantly related to the concentration of formaldehyde (P 〈 0.05 ). There were negative correlation between natural ventilation duration and indoor formaldehyde concentration and positive correlation between temperature and indoor formaldehyde concentration. Furniture in house related to higher indoor formaldehyde concentration. [ Conclusion ] The results of current study suggest that indoor air pollution in recent decorated apartments should be considered. Enhancing ventilation after decoration is recommended ot reduce indoor air pollution.
