吉林市城郊某居民区新装修住宅甲醛污染状况调查

Formaldehyde pollution survey for decoration of new residential households in Jilin City

目的:调查居室装修后空气中甲醛的污染状况并探讨其影响因素。方法:选择吉林市城郊某远离工业生产的新建住宅小区,抽取50户装修不超过半年的住户,采用便携式甲醛测定仪进行室内甲醛浓度的测定,并结合调查问卷对留居者进行甲醛浓度相关影响因素的调查。结果:在装修半年内的50户住户中,不同功能类型房间的甲醛浓度均值不同,贮藏间甲醛浓度明显高于其它房间(P<0.05),居室装修后不同时间甲醛浓度均值不同,并有显著性差异(P<0.05),不同通风情况影响各不同功能类型房间的甲醛浓度,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甲醛浓度均值(P<0.05)。结论:该市城郊某居民区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。适当从简装修、装修后良好通风半年以上可使居室甲醛的浓度降低到国家标准规定的范围内。

Objective To explore the formaldehyde pollution in the air for the decoration room and the relevant factors. Method A new residential quarter away from industrial production was chosen. 50 households which were decorated not more than half a year were selected. Portable meter was used to measure the concentration of indoor formaldehyde. Meanwhile, questionnaire was carried out on the concentration of formaldehyderelated factors. ResultsDifferent types of function rooms had different average formaldehyde concentration. Formaldehyde concentration in storage rooms were significantly higher than that in other rooms （P〈0. 05）, Formaldehyde concentration was significantly different at different time （P〈0. 05）. Different ventilation condition resulted in different formaldehyde concentration in rooms. Average formaldehyde concentration was significantly lower in rooms with regular ventilation than that in those with occasional ventilation （P〈0. 05）. Conclusions Formaldehyde pollution is very serious in this residential area. The factors of indoor formaldehyde concentration are degree of decoration, the empty duration after the ventilation and the ventilation condition. Simple decoration and good ventilation after more than six months will enable the formaldehyde concentration to reduce to the national standard.
