摘　　要：目的了解居室装修后室内空气中主要挥发性有机物污染状况。方法对居室装潢后不同时间的居室室内空气中甲醛、苯、甲苯、二甲苯、空气耗氧量进行测定,并与室外空气标准进行对比。结果装修后居室空气中甲醛、苯、二甲苯及空气耗氧量均严重超标,12个月后浓度虽明显下降,但甲醛和空气耗氧量超过室外空气标准。结论装修后相当长一段时间内居室空气中挥发性有机物污染严重,装修后1年内入住可能至少导致为期1~2年的免疫伤害。Objective To study the pollution status of volatile organic compounds(VOCs)in indoor atmosphere in the dwellings which underwent interior decoration.Methods After the dwellings have been decorated in 2mon,6mon,12mon,the concentrations of formaldehyde,dimethylbenzene,benzene,methylbenzene and oxygen consumption in the indoor atmosphere were measured respectively and compared with the air atmosphere outside.Results Two months after the dwellings were decorated,the VOCs concentrations achieved the highest level and as followed,the concentrations decreased in the next 12 months but were still higher than that of outside atmosphere.Conclusion After the decoration,VOCs concentrations in the indoor atmosphere were significantly higher than that of standard air which might induce serious complaints of immune system in the period of 1-2 years for people who move in the house which underwent interior decoration in the past one year.
