Particulate matter (PM) is an important factor of atmospheric haze and indoor air pollutant which affects human health. This paper takes high-rise apartment in one university as an example to monitor the levels and variations of indoor and outdoor PM1, PM_2.5, PM₁₀ and TSP. The results show that there is high PM pollution both in indoor and outdoor air, with the concentration of PM₁₀ being (65.5±20.0)~(142.0±16.9) μg/m³, which is lower than the National Indoor Air Standard. Howerver, indoor PM_2.5 and PM1 are (52.2±14.3)~(111.5±12.2) μg/m³ and (50.6±13.9)~(108.7±11.9) μg/m³, respectively, i.e., indoor PM_2.5 is about 3~5 times higher than the USEPA standard. The dominant PM in indoor environment is fine particle while coarse particle in the outdoor air. The preliminary study shows the height has no direct relation with the PM pollution.
