Simultaneous air monitoring inside and outside of three domestic environments in residential and industrial communities were conducted to evaluate infiltrations of outdoor aerosols into indoor environments, and indoor aerosol characteristics. The relationships of total (TSP), inhalable (< 10 microns, PM10) and respirable (< 2.5 microns, PM2.5) suspended particles were compared. It was found that the fractions of the indoor (20%) and outdoor (40%) PM10 levels exceeding 150 micrograms/m3 were substantial. In addition, it was indicated that indoor TSP and PM10 concentrations (R2 = 0.99) were well correlated with their corresponding outdoor levels. Moreover, there was a close relationship between the paired PM10 and PM2.5 levels indoors (R2 = 0.75) and outdoors (R2 = 0.83). The average indoor/outdoor (I/O) and median I/O ratios observed were 0.60. Therefore, steps to mitigate the situations with particulate levels above ambient particulate standards requires further study.
在住宅和工业社区的三种家庭环境的室内和室外同时进行空气监测，以评估室外气溶胶向室内环境的渗透情况以及室内气溶胶特征。比较了总悬浮颗粒物（TSP）、可吸入颗粒物（<10微米，PM10）和可呼吸颗粒物（<2.5微米，PM2.5）之间的关系。结果发现，室内（20%）和室外（40%）PM10水平超过150微克/立方米的比例相当大。此外，研究表明室内TSP和PM10浓度（R2 = 0.99）与其相应的室外水平具有良好的相关性。而且，室内（R2 = 0.75）和室外（R2 = 0.83）的成对PM！0和PM2.5水平之间存在密切关系。观察到的室内/室外（I/O）平均比值和中位数I/O比值为0.60。因此，采取措施减轻颗粒物水平高于环境颗粒物标准的情况需要进一步研究。
