摘　　要：目的了解荆门市装修后居室污染情况。方法选择2006—2008年装修时间在12个月以内的70户装修家庭,检测室内空气中的甲醛、氨浓度,并进行分析。结果氨均未检出,甲醛超标率为72.56%。卧室、书房、客厅超标率分别为85.91%、80.00%、48.57%,经χ2检验,三者间差异有统计学意义(P<0.01)。装修后3个月以内、3～6个月、7～12个月甲醛超标率分别为89.01%、66.67%、49.12%,经χ2检验,三者间差异有统计学意义(P<0.05)。结论居室装修导致的室内空气污染,以甲醛最严重,甲醛的浓度超标率因房间功能不同差异有统计学意义,并随着装修后时间的间隔延长而呈下降趋势。[ Objective ] To understand the indoor air pollution after decoration in Jingmen City [ Methods ] Totally 70 houses which were decorated within 12 months during 2006--2008 were selected, the formaldehyde and ammonia concentration of indoor air were detected. [Results]Ammonia were not detected in all air samples, the over standard rate of formaldehyde was 72.56%. The over 2 standard rate of formaldehyde in bedroom, study room and living room was 85.91%, 80.00%, 48.57%, respectively, proved by χ2 test, the differences were significant between them（ P 〈 0.01）. We also collected air samples within 3 months after decoration, 89.01% of them exceed the recommended concentration of formaldehyde. And samples from 3 months to 6 months and from 6 months to 12 months,66. 67% and 49. 12% of them exceeded the recommended concentration respectively,the differences were significant between them { P 〈 0. 05 }. [ Conclusion ] House decoration causes indoor air pollution, especially for formaldehyde. The difference of formaldehyde over standard rate between different rooms was significant in terms of room function; and the formaldehyde concentration decreased with time lapse.
