摘要
目的:了解杭州市新装修居室常见污染物污染水平和分布状况,探讨居室装修对室内空气质量的影响,为控制室内空气污染提供科学依据。方法:采用现场环境卫生学调查和室内空气监测相结合的方法,在2006年9月至2008年10月期间对112户新装修居室室内空气中的甲醛、苯、甲苯、二甲苯、总挥发性有机物浓度进行监测。结果:112户居室主要污染物的点超标率和户超标率分别为甲醛22.5%和38.7%,总挥发性有机物63.0%和80.0%,苯2.8%和2.8%,甲苯7.5%和7.5%,二甲苯9.3%和9.3%。总挥发性有机物超标率最高。监测时室内环境温度与污染物浓度有关,25℃及以上组甲醛和总挥发性有机物的浓度高于25℃以下组(P<0.05)。卧室和书房中甲醛和总挥发性有机物浓度高于客厅、厨房和餐厅。结论:装修造成严重的室内空气污染,甲醛和总挥发性有机物是造成室内环境污染的主要因素,其次是苯系物。室内空气污染物的浓度随着室温的升高而增大,家具较多的卧室和书房污染物超标严重。建议加强居室的通风换气等措施,降低污染物的浓度,保护居民健康。
Objective：To investigate the interior airborne pollution in newly decorated apartments in Hangzhou,to explore the Influencing Factors for interior decoration induced pollution and provide scientific evidences for the control of indoor air pollution.Methods：From September 2006 to October 2008,we determined the concentrations of formaldehyde,benzene,toluene,xylene and total volatile organic compounds（TVOC） in interior air in 112 newly decorated apartment.Results：The point exceeding standard rates and the family exceeding standard rates of the surveyed pollutants in the 112 houses respectively were 22.5% and 38.7% for formaldehyde,63.0% and 80.0% for the total volatile organic compounds,2.8% and 2.8% for benzene,7.5% and 7.5% for toluene,and 9.3% and 9.3% for Xylene.The exceeding rate of TVOC was the highest among the surveyed pollutants.The concentrations of pollutants were associated with the interior-temperature in the apartment.The concentrations of formaldehyde and TVOC in temperature of 25℃ or above were higher than those in temperature below 25℃（P〈0.05）.The concentrations of formaldehyde and TVOC in the bedroom and study room were higher than those in the living room,kitchen and dining-room.Conclusion：Interior-decoration would cause serious indoor airborne pollution.Formaldehyde and total volatile organic compounds are main pollutants to cause indoor environmental pollution,and the next is benzene.The concentrations of indoor air pollutants are positively associated with room temperature.It is suggested that measures such as ventilation and air exchanging should be strengthened to reduce the concentrations of pollutants and to protect residents′ health.
