【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。
[Abstract]:To investigate the status of formaldehyde pollution in the indoor air after decoration and its influencing factors. The formaldehyde content in indoor air was determined by chemical spectrophotometry with 73 sets of decorated houses as the research object and 11 sets of blank houses as control. The average concentration of formaldehyde in furniture was 0.760 mg / m ~ (3) higher than that in air (0.102 mg / m ~ (3)), and the concentration of formaldehyde and the rate of exceeding standard in indoor air decreased continuously with the extension of decoration time, especially after 3 months. Within one week after the completion of the decoration, the formaldehyde excess rate in the air of complex decoration reached 100 percent, which was nearly 20 percent higher than that of the simple decoration, and the formaldehyde concentration increased with the increase of indoor temperature and humidity. Formaldehyde pollution in newly decorated rooms is very serious, furniture is one of the main pollution sources, the main factors affecting indoor formaldehyde content are the quality of decoration materials, dosage, decoration time, indoor temperature, humidity, Maintaining good ventilation is conducive to formaldehyde diffusion and can effectively reduce the degree of indoor formaldehyde pollution.
