【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(P0.05),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。
[Abstract]:[objective] to understand the present situation of indoor air formaldehyde pollution in newly decorated houses in Baoshan District, and to provide scientific basis for controlling indoor air pollution. [methods] from April 2008 to December 2009, 20 newly decorated (not more than 6 months) houses in Baoshan District were investigated and the formaldehyde concentration in indoor air was detected. [results] formaldehyde exceeded the standard seriously, the indoor formaldehyde concentration was 0.001 81.90 mg / m ~ (3), and the household qualified rate was only 40. The results of multivariate logistic analysis showed that the effect of natural ventilation time, temperature and furniture on formaldehyde concentration was statistically significant (P 0.05), and the natural ventilation time was negatively correlated with formaldehyde concentration. There was a positive correlation between formaldehyde concentration and high temperature (鈮，
