【摘要】：目的了解居室装修后空气中甲醛的污染水平,分析可能存在的污染原因并提出控制措施。方法选择贵阳市两城区新装修居室,按装修程度的不同分为低、中、高3个装修水平组,每组各8户,比较装修前对板材进行封闭底漆处理(对照组)与同期没有采取任何处理的板材(试验组)甲醛释放浓度。甲醛的测定按照《居住区大气中甲醛卫生检验标准方法》(GB/T 16129-1995)分光光度法进行。结果低装修水平组甲醛浓度范围为0.049～0.17 mg/m3,中位数0.095 mg/m3,对照组为0.019～0.073 mg/m3,中位数0.051mg/m3(P0.05);中装修水平组浓度范围0.072～0.46 mg/m3,中位数0.24 mg/m3,对照组为0.052～0.16 mg/m2,中位数0.078 mg/m2(P0.05);高装修水平组浓度范围0.47～1.71 mg/m3,中位数0.87 mg/m3,对照组为0.18～0.44 mg/m2,中位数0.26 mg/m2(P0.05)。结论居室装修甲醛污染主要与人造板材装填量有关,在居室装修中必须控制人造板材的数量、质量以及装修前的处理,居室空气中甲醛污染才能控制在国家标准值以下。
[Abstract]:Objective to understand the level of formaldehyde pollution in indoor air after decoration, analyze the possible causes of pollution and put forward control measures. Methods the newly decorated rooms in two urban areas of Guiyang City were divided into three groups according to the degree of decoration: low, middle and high decoration level groups, 8 households in each group. The concentration of formaldehyde in the control group was compared with that in the control group. The determination of formaldehyde was carried out in accordance with the Standard method for the hygienic examination of formaldehyde in the Air of Residential area (GB/T 16129-1995). Results the range of formaldehyde concentration in the low decoration level group was 0.049 ~ 0.17 mg/m3, and the median value of 0.095 mg/m3, in the control group was 0.019 ~ 0.073 mg/m3, 0.051mg/m3 (P0.05). The median concentration of 0.072 mg/m3, and 0.24 mg/m3, in the middle decoration level group was 0.052 卤0.16 mg/m2, and 0.078 mg/m2, respectively (P0.05). The concentration range of 0.47 ~ 1.71 mg/m3, in the high decoration level group was 0.87 mg/m3,. The median 0.26 mg/m2 in the control group was 0.18 ~ 0.44 mg/m2, (P0.05). Conclusion formaldehyde pollution in indoor decoration is mainly related to the loading quantity of artificial panels. The quantity, quality and treatment of artificial plates must be controlled in the decoration of living room, and the formaldehyde pollution in indoor air can only be controlled below the national standard value.
