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.en-US室內外相關性可吸入性氣膠可呼吸性氣膠室內空氣品質環境衛生INDOOR/OUTDOOR RELATIONSHIPINHALABLE PARTICLERESPIRABLE PARTICLEINDOOR AIR QUALITYENVIRONMENT HEALTHjournal article
