摘　　要：为了研究室内甲醛浓度散发规律,对天津某住宅小区房间进行为期40 d甲醛浓度现场测试,测试区域为餐桌、电视柜、沙发以及房间几何中心区域.实测发现甲醛浓度由最高值0.46 mg·m^(-3)开始降低后进入以0.19 mg·m^(-3)平稳散发阶段,31 d后接近于直线状态,是处理甲醛污染的最佳时机.并且发现在沙发区域甲醛浓度值最高,达到0.33 mg·m^(-3),在房间几何中心甲醛浓度值最低为0.01 mg·m^(-3),在封闭条件下散发1个月后,甲醛浓度4个区域均不能达到室内空气质量标准要求,超标倍数达到了1—4倍,沙发区域比其他3个区域甲醛浓度都高出3倍左右.In order to study the distribution of indoor formaldehyde concentration,formaldehyde concentration field test was made in a residential house in Tianjin for a period of 40 days,and the test area incluoled dining table,TV cabinet,sofa and room geometry center.It was found that the formaldehyde concentration decreased from 0.46 mg·m-3to 0.19 mg·m-3and stablized after 31 d.This is the best time to deal with the pollution of formaldehyde.The highest concentration of formaldehyde was found in the sofa area,reaching 0.33 mg·m-3,and the lowest concentration of formaldehyde was in the room geometry center（0.01 mg·m-3）.After one month closure formaldehyde concentration did not meet the indoor air quality standard,exceeding the standard by 1—4 times.Formaldehyde concentration in the sofa area were about 3 times higher than the other three areas.
