【摘要】：[目的]了解不同装修类型的居室空气中甲醛的污染现状及其衰减情况。[方法]根据装修时所使用人造板材数量和类型分3组:低装修类型组、高装修类型组和家具装填组(在低装修类型的基础上,采用装填各类人造板材家具),每组12户;另设1组同期未使用人造板材和外购家具入户的12户为对照组。对不同装修类型居室空气中的甲醛污染情况进行为期7个月的监测,首次监测在装修完工后1个月,以后每个月监测1次。按照GB/T 16129—1995《居住区大气中甲醛卫生检验标准方法分光光度法》测定甲醛浓度。[结果]低、高装修类型组甲醛浓度分别为(0.084±0.040)mg/m3和(0.19±0.28)mg/m3(P0.01);家具装填组甲醛浓度(0.49±0.56)mg/m3高于低、高装修类型组(均P0.05)。3个不同装修类型组与对照组相比差异均有统计学意义(F值分别为3.12,6.67,8.93,均P0.05)。装修213天后,低、高装修类型组及家具装填组的空气甲醛浓度分别为(0.012±0.028),(0.083±0.041)和(0.087±0.30)mg/m3,与对照组比较,低装修类型组差异无统计学意义(P0.05),高装修类型组和家具装填组均高于对照组(均P0.05)。[结论]人造板材用量和家具的装填可影响居室装修后甲醛的污染水平,经7个月后高装修组和家具装填组室内空气中甲醛仍处于较高水平。
[Abstract]:[objective] to understand the present situation and attenuation of formaldehyde pollution in indoor air of different decoration types. [methods] according to the number and type of artificial panels used in decoration, there are three groups: low decoration type group, High decoration type group and furniture packing group (on the basis of low decoration type, all kinds of artificial panel furniture are loaded, each group of 12 households; Another group of 12 households that did not use artificial panels and purchased furniture in the same period were used as control group. The formaldehyde pollution in the indoor air of different decoration types was monitored for 7 months, and the first time was one month after the completion of the decoration. The concentration of formaldehyde was determined once a month in accordance with GB/T 16129-1995 < Standard method for hygienic examination of formaldehyde in Residential area > Spectrophotometry >. [results] low, The formaldehyde concentrations in the high decoration type group were 0.084 卤0.040 mg / m 3 and 0.19 卤0.28 mg / m 3 respectively, and the formaldehyde concentration in the furniture filling group was 0.49 卤0.56 mg / m 3 higher than that in the high decoration type group (all P 0.05%). There were significant differences in F value between the three different decoration types group and the control group, respectively. The air formaldehyde concentrations in the low, high decoration type group and furniture loading group were 0.012 卤0.028, 0.083 卤0.041) and 0.087 卤0.30 mg / m3, respectively, compared with those in the control group. There was no significant difference in the low decoration type group (P 0.05). The high decoration type group and the furniture loading group were higher than the control group (P 0.05). [conclusion] the amount of artificial panel and the filling of furniture could affect the formaldehyde pollution level after decoration. After 7 months, formaldehyde in indoor air of high decoration group and furniture packing group was still in high level.
