摘要
调查了装修后的住宅和办公室室内空气中挥发性有机物 ,同时对室外空气进行了调查。共检出 2 0多种挥发性有机物。装修后室内甲醛和苯及其他苯系物含量明显高于室外。装修后室内空气甲醛质量浓度为 0 1～ 2 4mg m3,在装修后短期内甲醛质量浓度更高 ,有时达到13 4mg m3;苯质量浓度为 0 0 3～ 0 17mg m3。装修一年内甲醛、苯和苯乙烯普遍超标。卤代烃含量一般是数个 μg m3,与室外没有显著性差异。
The volatile organic compounds of air in the department room and the office after decoration were sampled and analyzed,while the outdoor air was investigated.Over 20 kinds of VOCs were detected in indoor air.The concentration of indoor air is higher than that of outdoor air.In one year after decoration,formaldehyde concentration of indoor air is 0 1～2 4 mg/m\+3,and in a short time after decoration it is higher,sometimes up to 13.4 mg/m\+3;benzene concentration of indoor air is 0.03～0.17 mg/m\+3.In one year after decoration,formaldehyde,benzene and styrene generally overpass the national standards.Halogenated hydrocarbon concentration of indoor air is 1～10 μg/m\+3,without significant difference from that of outdoor air.
