摘　　要：目的探讨新装修居室空气甲醛污染的变化规律。方法使用4160_2型甲醛分析仪 ,测定装修后不同时期的居室空气中的甲醛浓度。结果新装修的居室关闭门窗10min后 ,空气中甲醛浓度已超过居室卫生标准的近2倍 ;关闭门窗30min后 ,甲醛浓度达到最高浓度的51 % ,420min时则达到最高浓度 (0.652mg/m3)。随着时间的延长 ,室内空气甲醛的浓度逐渐降低 ,4个月后达到卫生标准要求。研究全过程室温为27.8～29.9℃。结论新装修居室的空气中甲醛污染严重 ,在装修后头4个月内要加强居室通风换气 。Objective To study the characteristics of the variations of formaldehyde concentration in indoor air of newly decorated living rooms. Methods The formaldehyde concentrations in indoor air of newly decorated rooms were determined with model 4160_2 formaldehyde analyzer during the different periods after decoration. Results At the 10th minute after closing all the windows and doors in the newly decorated rooms, the formaldehyde concentrations of indoor air exceeded the standard nearly as high as 2 times, reached 51% of the peak concentration at the 30th minute, and reached the peak concentration (0.652 mg/m 3) at the 420th minute, then decreased gradually with the prolongation of periods after decoration and accorded with the sanitary standard in the 4th month after decoration. The whole study was carried out at the indoor air temperature of 27.8～29.9 ℃. Conclusion The indoor air pollution by formaldehyde was serious in newly decorated living rooms. The ventilation should be enhanced during the first 4_month period after decoration, so that the formaldehyde concentration could be decreased gradually.
