Analysis of air pollution in decorating residences in Baoshan District of Shanghai

[ Objective] To know the indoor air pollution caused by decoration, provide a reference for relevant departments to carry out the indoor air pollution control. [ Methods ] By using the questionnaire survey and field detection, the air pollution status of resi- dences after decoration of 84 households in Baoshan District was investigated and analyzed. [ Results ] There was a significant differ- ence in the over standard rate of formaldehyde among different housing types, which the over standard rate in the schoolroom （ 26. 19% ） and the living room （ 15.48% } was the highest and the lowest respectively. The concentration of formaldehyde reached the peak 4-12 months after the completion of the decoration, and the over standard rate was 46.15%. Multiple conditional logistic regression analysis indicated that the over standard rate of formaldehyde was related to the furniture material and the temperature of testing. The levels of pollution caused by benzene, toluene and xylene were relatively low. [ Conclusion ] The indoor air pollution of residences is serious after decoration, and the relevant measures, such as adopting solid wood furniture, are helpful to reduce pollu- tion.
