【摘要】：了解长沙市装修居室室内空气质量,笔者于2006年9月10日—10月30日在长沙市区随机抽取80套完成整体装修2个月但尚未入住的新建住房,对其进行空气中甲醛、苯、甲苯、二甲苯、总挥发性有机物(TVOCs)进行检测。同时对污染严重的住房,于2007年5月随机抽取10套进行复检。结果显示,装修后约2个月,居室空气中甲醛、TVOCs 污染严重,主卧室甲醛超标率为85%(68/80),书房 TVOCs 超标率为77.5%(62/80)。主卧室和书房空气污染物超标率高于客厅。随着装修竣工时间的延长,TVOCs 浓度明显下降,而甲醛浓度降低较不明显。装修居室空气污染物以甲醛和 TVOCs为主;不同功能的房间空气污染物浓度有差异;居室空气污染物浓度随装修后时间延长呈下降趋势。
