【摘要】 目的是评价某办公楼室内装修后空气中有害物质污染水平。方法用随机抽取不同类型,布点39个,对空气中甲醛、苯、氨进行监测。结果为该办公楼室内甲醛、苯、氨平均浓度均超过国家(GB/T18883～2002)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12．8％。不同楼层甲醛、苯、氨浓度无显著性差异(P＞0．05),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＜0．05)。结论是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。更多还原

【Abstract】 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 formal- dehyde.Benzene,ammonia indoors air were all overproof of national hygiene standard(GB/T18883-2002).The average overproof was1.1times,1.7times,0.3 times respectively.The benzene qualified rate of 36% was the highest,the formaldehyde of 12.8% was the low- est.The concentration of formaldehyde,benzene,and ammonia indoors air of different layers was no significant(P＞0.0.5),but the concentra- tion of formaldehyde,benzene,and ammonia indoors air of different type room in same layer was significant(P＜0.05).Conclusions To con- trolling air pollution of indoors decoration,green environmental protection decorated material should be adopted,ventilation and changing air should he enhanced and fitly decorated reason should be selected.更多还原
