摘要
研究北京市室内空气污染特征,以了解新装修居室空气污染状况,并探讨其影响因素,为控制室内空气污染提供科学依据.本研究对2007年1月—2015年12月北京市新装修在12个月以内的390套居民住宅和47个办公场所,共2478个房间进行室内空气中甲醛、总挥发性有机物(TVOC),苯及甲苯、二甲苯、氨、氡的检测.结果表明,所有监测房间中,空气中甲醛超标率分别为50.8%,最高浓度超标12.9倍;TVOC超标率为76.3%,最高浓度超标55.8倍,苯、甲苯和二甲苯超标率分别为1.8%、22.9%和26.9%,最高浓度分别为超标4.5倍、32.6倍、57.9倍;氨超标率为0.09%,最高浓度超标3.4倍;氡无超标.北京市因装修导致的室内空气污染较为严重,应采取适当的污染防治措施,减少室内环境污染对人体产生的损害.
This report investigated on the pollution character of indoor air in Beijing. The indoor air pollution and influential factors were discussed to provide theoretical basis for controlling indoor air pollution. Between January 2007 to December 2015,air samples were collected from 2478 rooms of390 residential houses and 47 offices in Beijing which were redecorated in less than 12 months.Formaldehyde, total volatile organic compounds（ TVOC）, benzene, methylbenzene,dimethylbenzene,ammonia and radon were investigated. The results indicate that the rate of over standard of formaldehyde was 50. 8%,and the highest concentration was 12. 9 times above the standard. The rate of over standard of TVOC was 76. 3%,and the highest concentration exceeded the standard by 55. 8 folds. The rates of over standard of benzene, methylbenzene and dimethylbenzene were 1. 8%,22. 9% and 26. 9%, respectively. The highest concentration exceeded the standards by 4. 5,32. 6 and 57. 9 folds. The rate of over standard of ammonia was 0.09%,and the highest concentration was 3. 4 times above the stardand. The concentration of radon did not exceed the standard. Indoor air pollution caused by room decoration is serious in Beijing.Prevention and control should be proposed to reduce the harm to human health.
