摘要
调查装修后居室空气中甲醛污染现状并探讨其影响因素。选择73套装修居民住宅为研究对象,11套毛坯房为对照,利用化学分光光度法测定室内空气中甲醛含量。新装修居室空气超标率为61.4%,家具中甲醛平均质量浓度(0.760mg/m3)显著高于空气中质量浓度(0.102 mg/m3);随着装修后时间延长,室内空气中甲醛浓度和超标率不断下降,尤其是3个月后非常明显;在装修完工后1周内,复杂装修空气中甲醛超标率达100%,比简单装修高出近20个百分点;甲醛浓度随室内温度、湿度的升高呈上升趋势。新装修居室甲醛污染相当严重,家具是其主要污染源之一,影响室内甲醛含量的因素主要是装修材料的质量、用量、装修时间和室内温度、湿度,保持良好的通风有利于甲醛扩散,可以有效地减轻居室内甲醛污染程度。
This paper is aimed to investigate formaldehyde pollution in indoor air of decoration and its influencing factors.Taking 73 newly decorated apartments（included furniture） as the study example and 11 roughcast apartments as the contrast,acetylacetone spectrophotometr method is applied to measure the concentration of formaldehyde.The air in the newly decorated apartment exceeds the standard 61.4% and the average concentration of formaldehyde（0.760 mg/m3）in furniture is remarkably higher（0.102 mg/m3）than that in air;It is shown that the concentration of formaldehyde and exceeding rate is decreased with the time passed,especially after three months;in one week after the decoration,the formaldehyde exceeds the standard 100% in indoor air of complex decoration,higher 20% than that in simple decoration;the concentration of formaldehyde gradually rises with the increase of indoor temperature and humidity.The formaldehyde pollution in newly decorated apartment is greatly serious and furniture is one of the main pollution sources.The factors affecting the concentration of formaldehyde mainly include the quality and quantity of the decoration materials,time after decoration and indoor temperature and relative humidity.Keeping ventilation is beneficial to the diffusion of formaldehyde and can effectively reduce formaldehyde pollution.
