| 摘 要： | 目的了解当前住宅室内空气PM2.5和PM10的污染水平及其与室外大气浓度的关系。方法选择10户市区常住家庭,采用单孔多段冲击式颗粒物采样仪进行室内外空气PM2.5、PM10浓度的同时监测。结果非采暖期室内空气PM2.5和PM10的浓度范围分别为27.0～272.9μgm3和42.9～309.6μgm3;采暖期分别为20.7～251.4μgm3和34.0～283.9μgm3。PM2.5与PM10浓度之间呈良好的直线相关关系。室内外颗粒物浓度的相关关系在非采暖期和采暖期有所不同。结论住宅室内空气颗粒物污染比较严重,今后应进一步研究室内颗粒物的污染规律,探讨颗粒物对人群健康的影响。

| 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. |
