【摘要】 [目的 ]分析新装修居室内甲醛污染状况及特点 ,探讨室内甲醛浓度随装修完工后时间长短的变化规律。 [方法 ]检测分析厦门市区 10 1套居室的 3 91个采样点装修后室内空气中的甲醛浓度。[结果 ]在这些采样点中 ,空气甲醛浓度>0 10mg/m3 的超标者占 68 0 %,超标 2倍以上者 3 1 2 %;套房内空气甲醛浓度均值为书房 >卧室 >客厅 ;空气甲醛浓度的峰值不是出现在装修完工后的初期 ( 1个月内 ) ,而是出现在更后些时间段 ( 2～ 3个月 )。[结论 ]新装修居室的室内甲醛污染状况较为严重 (尤其是头 3个月 ) ,装修完 1年内都应注意室内的通风换气 ,以降低室内空气中的甲醛浓度更多还原

【Abstract】 To investigate indoor air pollution by formaldehyde (FD) and explore the concentration and changing tendency in newly decorated rooms \ FD concentration of 391 sampling points in 101 sets were detected and analyzed \ The sampling points of FD>0 10mg/m 3 (over national hygiene standard) were 68 0%, and 2 times higher than the standard were 31 2%;The mean level of FD concentration of reading room was higher than bedroom and bedroom higher than sitting room; The peak time of FD concentrations was in 2 3 months after decoration rather than in the first month \ The indoor FD pollution is serious in newly decorated rooms, especially in first three months Opening the windows frequently for one year can reduce FD concentration更多还原
