【摘要】：目的了解上海市宝山区装修致室内甲醛污染情况,为有关部门开展室内甲醛污染治理提供参考依据。方法采用问卷调查和现场检测,对宝山区84户居民家庭装修后居室甲醛污染及变化情况进行调查分析。结果不同房型甲醛超标率存在差异,其中书房较高(26.19%)、客厅较低(15.48%)。装修竣工后居民家庭房间甲醛超标率在4~12个月达峰值,超标率为46.15%。甲醛检测超标户至7~12个月复测时合格率达到95.52%,1年以上全部合格。多因素条件Logistic回归分析结果提示家具材质和检测时室温情况对甲醛超标有影响。结论居民家庭装修后室内甲醛超标较为普遍,采用实木家具等措施有利于甲醛消除。
[Abstract]:Objective to investigate the indoor formaldehyde pollution caused by decoration in Baoshan District, Shanghai, and to provide reference for related departments to carry out indoor formaldehyde pollution control. Methods 84 households in Baoshan District were investigated and analyzed on formaldehyde pollution and changes after decoration. Results there were differences in the excess rate of formaldehyde in different rooms, among which the study was higher (26.19%) and the living room was lower (15.48%). After the completion of the decoration, the rate of formaldehyde exceeding the standard reached the peak in 4 ~ 12 months, and the rate of exceeding the standard was 46.15. The qualified rate of formaldehyde was 95.52 by the time of 7 ~ 12 months. All of them were qualified for more than one year. The results of multivariate conditional Logistic regression analysis showed that furniture material and room temperature had influence on formaldehyde over standard. Conclusion the indoor formaldehyde exceeded the standard is more common after the household decoration, and the use of solid wood furniture is beneficial to the elimination of formaldehyde.
