摘要
目的:了解赣州市装修住房室内空气中甲醛浓度现况,探讨甲醛浓度的影响因素,提出室内环境中甲醛的控制措施。方法:本研究在赣州市共抽取样本72户,分别对抽到住户的客厅、主卧室和次卧室进行空气采样。对获得的样品采用乙酰丙酮分光光度法测定室内空气中甲醛浓度。参照《室内空气质量标准》中甲醛浓度限值进行评价,甲醛浓度1小时浓度限值为0.10 mg·m-3。结果:72户甲醛浓度检测总体水平低于国家规定的甲醛浓度限值0.10 mg·m-3。入住房间内的甲醛浓度低于未入住房间内的甲醛浓度;随着装修完成时间的延长,室内甲醛浓度下降;但研究没有发现不同类型房间内甲醛浓度有统计学差异。结论:住房内甲醛污染主要来源于住房装修材料及家具,随着装修完成时间的延长,甲醛浓度下降。
Objective： To understand the status of formaldehyde concentration in the indoor air of a residential district in Ganzhou,and to explore the influencing factors of the formaldehyde concentration,and put forward the control measures of formaldehyde in the indoor environment. Methods： Seventy two decorated house were selected in Ganzhou,and the air samples were collected at living room,master bedroom and guest bedroom. The formaldehyde concentration of these samples were measured by Acetylacetone Spectrophotometric method according to the national standard,Indoor Air Quality Standard. Results： The general level of formaldehyde concentration was lower than the national provisions of formaldehyde concentration limit,0. 1 mg · m-3. Further analysis showed that formaldehyde concentration of inhabited houses was lower than those never inhabited,and that the indoor air formaldehyde concentration was decreasing with the time of decoration completion going on. But the level of formaldehyde concentration among different types of rooms did not show significant statistical difference in the study. Conclusion： Indoor Air formaldehyde pollution mainly derives from decoration materials and furniture,and with the time elapse after decoration completion,the formaldehyde concentration is decreasing.
