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.
