摘要

为了解室内空气污染现状，依据《室内空气质量国家标准》（GB / T 18883－2002），对广东省具有代表性的427个单位的室内空气进行了采样分析。结果表明各项目平均浓度为：甲醛0.15 mg/m

苯、甲苯、二甲苯、TVOC分别为32.09、227.79、134.72和769.66 μg/m

氡为74.38 Bq/m

氨为0.10 mg/m

超标率分别为43.83%、335%、31.51%、19.18%、43.59%、0.57%、0。因此，认为广东室内空气污染以有机物污染为主，VOCs污染严重且组成复杂，二甲苯与其他苯系物之间的相关性系数达到0.60以上，较苯与其他苯系物之间的相关系数（

0.30）大。

Abstract

In order to study indoor air pollution

eight air pollutantsformaldehyde

benzene

methylbenzene

ethylbenzene

dimethylbenzen

TVOC

Rn and NH3 collected from 427 apartments in Guangdong Province were tested according to the indoor air quality standards（GB / T 18883－2002）. The results indicate that concentrations of formaldehyde

benzene

methylbenzene

TVOC

Rn and NH3 exceed 43.83%

3.35%

31.51%

19.18%

43.59%

and 0.57% of the standards

respectively. Indoor air is mainly polluted by organic pollutants. VOCs contain many complex components. Correlation coefficient between dimethylbenzen and other benzene series is above 0.60

much higher than that between benzene and other benzene series (<0.30).
