| 摘 要： | 以西安市冬季某研究生高层公寓为监测对象, 通过1 min 时间间隔同步监测, 研究了不同楼层室内外空气中颗粒物PM1、PM2.5、PM10以及总悬浮颗粒物TSP 的质量浓度、分布状况与变化特征。结果表明, 西安市冬季高层公寓存在严重的颗粒物污染, 室内粗颗粒物PM10质量浓度为(65.5±20.0)~(142.0±16.9)μg/m3, 略低于室内空气质量标准, 但室内细颗粒物PM2.5及超细颗粒物PM1分别为(52.2±14.3)~(111.5±12.2)μg/m3和(50.6±13.9)~(108.7±11.9)μg/m3, 其中PM2.5质量浓度占总悬浮颗粒物TSP 的50%以上;室外以粗颗粒物PM10为主, 楼层高度与颗粒物质量浓度之间无显著关联。 |

| Abstract: | 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, PM2.5, 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 PM2.5 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 PM2.5 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. |
