Abstract: 目的探讨因装修导致室内污染的特征和规律,为预防控制提供科学依据.方法新建小区住宅卫生学调查均采用问讯填写调查表方式;监测方法和评价标准按照<室内空气质量标准>(GB/T18883-2002),对30户新装修住宅的141个监测点进行空气中有害污染物测定.结果甲醛和总挥发性有机物(TVOC)在新装修居室内空气中有超标,以甲醛超标严重,超标率达60.99%,TVOC超标率为26.95%;居室各房间均有分布,以主卧和书房浓度较高,甲醛最高超标8.5倍;TVOC最高超标7.7倍;装修6个月后,污染物明显下降,但在冬季装修的居室会在来年夏季出现污染物浓度回升的现象.结论甲醛和TVOC是新装修居室内空气中主要污染物,超标严重的主要分布在装载度商的房间;装修季节对室内空气中污染物浓度有明显影响,春夏季温度高的季节装修好于冬季;除特殊情况外,一般在装修好6个月后,甲醛等污染物已降至较低水平,最后对防治污染从不同角度提出了防制对策.
