Abstract

OBJECTIVE

To investigate the indoor air concentration of particulate matter in residential house and its relationship with ambient pollution level.

METHODS

Indoor and outdoor air level of PM2.5 and PM10 were monitored in 10 residential houses in downtown area.

RESULTS

In the non-heating period, the indoor air level of PM2.5 and PM10 were 27.0 - 272.9 microg/m3 and 42.9 - 309.6 microg/m3, respectively. In the heating period, PM2.5 and PM10 were 20.7 - 251.4 microg/m3 and 34.0 - 283.9 microg/m3, respectively. There were good correlation between the indoor air concentrations of PM2.5 and PM10. The relationships between the indoor and outdoor air concentrations of PM2.5 and PM10, however, were not clear.

CONCLUSION

Our results showed that there were serious indoor air pollution of particulate matter in residential house. Further research will be needed to clarify the characteristics of indoor air particulate matter pollution and its influence on resident.

摘要

目的

调查住宅室内空气中颗粒物的浓度及其与环境污染水平的关系。

方法

对市区10所住宅的室内和室外空气中PM2.5和PM10的水平进行监测。

结果

在非供暖期，室内空气中PM2.5和PM10的水平分别为27.0 - 272.9微克/立方米和42.9 - 309.6微克/立方米。在供暖期，PM2.5和PM10分别为20.7 - 251.4微克/立方米和34.0 - 283.9微克/立方米。室内空气中PM2.5和PM10的浓度之间存在良好的相关性。然而，PM2.5和PM10的室内外空气浓度之间的关系并不明确。
