摘要
目的调查装修后居室空气中甲醛的污染状况并探讨影响因素。方法选择武汉市区几个新建住宅小区,随机抽取100户装修不超过1年的住户,采用便携式甲醛测定仪检测室内空气中甲醛含量,并结合问卷调查调查装修情况及使用情况。结果在100个住户中,不同功能类型房间的甲醛浓度均值不同,各房间甲醛浓度超标率高低排序依次为主卧室、书房、次卧室和客厅;衣柜内甲醛浓度明显高于各房间(P<0.01);居室装修后不同时间甲醛浓度均值不同,其超标率差异有统计学意义(χ2=38.97,P<0.01);不同通风情况影响房间甲醛浓度,经常通风居室的甲醛浓度均值明显低于偶尔通风的同类居室(P<0.01)。结论该市大部分新装修住户室内甲醛污染较严重,影响室内甲醛浓度的因素主要有装修程度、装修后闲置时间及通风情况。
[Objective]To investigate the formaldehyde pollution in the air of newly decorated houses and explore the influencing factors.[Methods]Choosing several new residential areas in Wuhan City and 100 houses which were decorated within 1 year were selected.Portable formaldehyde analyzer was used to measure the concentration of indoor formaldehyde.Meanwhile,the questionnaire was carried out for the decoration and use investigation.[Results] In 100 houses,different types of rooms had different formaldehyde concentration,the formaldehyde concentration exceeding rate in order from high to low were master bedroom,study room,vip bedroom and living room.Formaldehyde concentration in wardrobe was significantly higher than that of other rooms（P0.01）.Formaldehyde concentration was different at different time after decoration,and the difference was significant（P0.05）.Different ventilation situation of rooms affected the air formaldehyde concentration.Average air formaldehyde concentration of room with regular ventilation was significantly lower than that of room with occasional ventilation（P0.01）.[Conclusion]The formaldehyde pollution in most new houses of this city is serious,and the main influencing factors of indoor formaldehyde concentration include degree of decoration,the time after the decoration and ventilation situation.
