办公楼装修室内空气有害物质监测分析

目的　评价某办公楼室内装修后空气中有害物质污染水平。方法　随机抽取不同类型房间 ,布点39个 ,对空气中甲醛、苯、氨进行监测。结果　该办公楼室内甲醛、苯、氨平均浓度均超过国家 (GB/T1 8883～ 2 0 0 2 )卫生标准 ,平均超标分别为 1 .1倍、1 .7倍、0 .3倍。苯监测合格率最高 ,为 36 % ;甲醛最低 ,为 1 2 .8%。不同楼层甲醛、苯、氨浓度无显著性差异 (P >0 .0 5 ) ,同一楼层不同类型房间室内甲醛、苯、氨浓度有显著性差异 (P <0 .0 5 )。结论　控制室内装修污染要选用绿色环保材料 ,加强室内通风换气 ,选择合适的装修季节。

Monitor and Analysis of Harmful Material of Indoors Air of Decorated Office Building

Objective To evaluation air pollution level of indoors of decorated 9 layers office building . Methods 39 points of different type room were selected randomly to monitor the concentrations of formaldehyde , benzene, ammonia indoors air. Results The concentrations of formaldehyde , benzene, ammonia indoors air were all overproof of national hygiene standard(GB/T18883-2002). The average overproof was 1.1times, 1.7times, 0.3times respectively. The benzene qualified rate of 36% was the highest, the formaldehyde of 12.8% was the lowest. The concentration of formaldehyde , benzene, ammonia indoors air of different layers was no significant (P>0.05), but the concentration of formaldehyde , benzene, ammonia indoors air of different type room in same layer was significant (P<0.05). Conclusions To controlling air pollution of indoors decoration, green environmental protection decorated material should be adopted, ventilation and changing air should be enhanced and fitly decorated season should be selected.
