2006-2009 Indoor Air Pollution Prevention and Control in Redecorated Rooms

目的：研究杭州市室内空气污染特征。方法：对杭州市装修完成的131套居民住宅和15个办公场所进行室内空气中甲醛、总挥发性有机物（TVOC）,苯及其同系物的检测。结果：办公室空气中甲醛、TVOC超标率分别为9.6%和26.5%,最高浓度超标分别为19倍和10倍,三苯未见超标。在131套住宅中,客厅、卧室、书房、厨房空气中甲醛、TVOC均严重超标,甲醛超标率在13.9%~27.1%之间,甲醛最高浓度超标4.4倍;TVOC超标率在51.3%~69.5%之间,最高浓度超标高达162.4倍;卧室中苯、甲苯和二甲苯超标率分别为11.5%、34.6%和46.2%,卧室和书房污染相对较重。结论：杭州市因装修导致的室内空气污染较为严重。

Objective：To study the indoor airpollution characteristic and control countermeasure.Methods： 15 office rooms and 131 houses that were redecorated chosen for the determination of formaldehyde,total volatile organic compounds（TVOC）,benzenem,methylbenzene and dimethyl benzene.Results： In the 15 office rooms,the rates of exceeding limit of formaldehyde,TVOC were 9.6% and 26.5% respectively.The concentration of benzenem,methylbenzene and dimethyl benzene did not exceed the limit.The concentrations of formaldehyde,TVOC in the investigated houses exceeded the standard limits greatly,the rates of exceeding limit of Formaldehyde,TVOC were13.9%~27.1% and 51.3%~69.5% respectively.In this kind of site,the rates of exceeding limit of benzenem,methylbenzene and dimethyl benzene were 11.5%,34.6% and 46.2%.Conclusion： Indoor air pollution caused by redecoration is serious in a certain degree in Hangzhou.
