【摘要】：了解長(zhǎng)沙市裝修居室室內(nèi)空氣質(zhì)量,筆者于2006年9月10日—10月30日在長(zhǎng)沙市區(qū)隨機(jī)抽取80套完成整體裝修2個(gè)月但尚未入住的新建住房,對(duì)其進(jìn)行空氣中甲醛、苯、甲苯、二甲苯、總揮發(fā)性有機(jī)物(TVOCs)進(jìn)行檢測(cè)。同時(shí)對(duì)污染嚴(yán)重的住房,于2007年5月隨機(jī)抽取10套進(jìn)行復(fù)檢。結(jié)果顯示,裝修后約2個(gè)月,居室空氣中甲醛、TVOCs 污染嚴(yán)重,主臥室甲醛超標(biāo)率為85%(68/80),書(shū)房 TVOCs 超標(biāo)率為77.5%(62/80)。主臥室和書(shū)房空氣污染物超標(biāo)率高于客廳。隨著裝修竣工時(shí)間的延長(zhǎng),TVOCs 濃度明顯下降,而甲醛濃度降低較不明顯。裝修居室空氣污染物以甲醛和 TVOCs為主;不同功能的房間空氣污染物濃度有差異;居室空氣污染物濃度隨裝修后時(shí)間延長(zhǎng)呈下降趨勢(shì)。
[Abstract]:To understand the indoor air quality of decorated rooms in Changsha City, from September 10 to October 30, 2006, the author randomly selected 80 new houses that had been renovated for 2 months but had not yet moved in, and detected formaldehyde, benzene, toluene, xylene and total volatile organic compounds (TVOCs) in the air. At the same time, 10 sets of seriously polluted housing were randomly selected for re-inspection in May 2007. The results showed that about 2 months after decoration, the pollution of formaldehyde and TVOCs in indoor air was serious. The exceeding standard rate of formaldehyde in master bedroom was 85% (68 鈮，
