【摘要】：目的了解居民住宅新装修后不同时间段室内甲醛浓度动态变化规律。方法选取银川市装修水平相近、装修规格相近且档次相近的居民住宅83户,按照装修后0～1、3、6、12个月各时间段进行室内空气甲醛浓度追踪调查。结果甲醛浓度在装修后4个时间段的超标率分别为95%,73%,41%,28%。装修12个月后,每天通风4 h以上的居室甲醛浓度为(0.11±0.07)mg/m3,通风不足4 h的居室甲醛浓度为(0.16±0.09)mg/m3,差异有统计学意义(P0.05)。装修后各时间段不同功能房间甲醛超标率不同,装修12个月后主卧超标率为37%,次卧为24%,厨房为21%,客厅为17%。结论居民新装修住宅室内甲醛污染较严重。装修后随时间的延长,超标率呈下降趋势。
[Abstract]:Objective to understand the dynamic changes of indoor formaldehyde concentration in different time periods after newly decorated residential buildings. Methods 83 households with similar decoration level, similar decoration specifications and similar grades in Yinchuan City were selected. Follow up the indoor air formaldehyde concentration in each period of 12 months after decoration. The results showed that the excess rate of formaldehyde concentration in the four time periods after decoration was 95 / 73 / 41 and 28.8 / 12 months later, respectively. The concentration of formaldehyde in room was 0.11 卤0.07 mg / m ~ (-3) for ventilation for more than 4 h per day and 0.16 卤0.09 mg / m ~ (3) for room ventilation for less than 4 h. The difference was statistically significant (P < 0.05). After decoration, the rate of formaldehyde exceeded the standard in different functional rooms was different. After 12 months of decoration, the over-standard rate of main bedroom was 37, second lying 24er, kitchen 21, living room 17.Conclusion the indoor formaldehyde pollution of residential newly decorated residence is more serious. After decoration, with the extension of time, the rate of exceeding standard shows a downward trend.
