【摘要】：目的了解南宁市新装住宅室内空气甲醛浓度水平、变化情况和影响因素。方法 2004-2011年,共选择新装住宅的1 437个房间,测量其室内空气甲醛浓度,将结果分别按不同的年份、月份和房间类型归类分析。结果 8年间,南宁市室内空气甲醛浓度总超标率为50.6%,超标率、超标倍数和浓度水平,总体呈下降趋势;1年中平均气温最高的6-8月超标率最高,5、9、10月等次高温月份次之,超标率和超标倍数的变化基本和温度的变化呈显著性正相关;"书房"的超标率(57.1%)、"其他"房间的超标倍数(20.0)分别最高,"客厅"(45.6%,9.00倍)则最低。结论温度是影响南宁等湿度变化较小地区的室内空气中甲醛浓度高低的主要因素,通风效果和单位面积内"含"甲醛的装修材料和家具数量是重要因素。
[Abstract]:Objective to investigate the level, variation and influencing factors of formaldehyde concentration in indoor air of newly installed residential buildings in Nanning. Methods from 2004 to 2011, a total of 1 437 rooms were selected and their indoor air formaldehyde concentrations were measured. The results were classified and analyzed according to different years, months and room types. Results during the past eight years, the total indoor air formaldehyde concentration exceeded the standard rate of 50.6, exceeded the standard rate, exceeded the standard multiple and the concentration level, and showed a downward trend. The highest average temperature in one year was in June-August, the highest in June and August, followed by the same month in October. The change of the rate of exceeding the standard and the ratio of exceeding the standard was significantly positively correlated with the change of temperature. The "study" exceeded the standard rate (57.1%), the "other" room exceeded the standard multiple (20.0) and the "living room" (45.6% 9.00 times) was the lowest. Conclusion temperature is the main factor that affects the concentration of formaldehyde in indoor air in Nanning, and the ventilation effect and the quantity of decoration materials and furniture "containing" formaldehyde in unit area are important factors.
