Abstract
ABSTRACTThe present work was conducted in a two-part study. In part I, the levels of indoor and outdoor PM10, PM2.5, and PM1was measured using real time GRIMM dust monitors. In part II, the performance of NAIs method was investigated on reduction of indoor concentration of PM in these residential buildings for the first time. Hourly average concentration and standard deviation (SD) of PM10in indoor and outdoor at residential buildings were 63.5 ± 27.4 and 90.1 ± 33.5 µg/m3, respectively. Indoor and outdoor concentrations of PM2.5in residential buildings were 39.4 ± 18.1 and 49.5 ± 18.2 µg/m3and for PM1the concentrations were 4.3 ± 7.7 and 6.5 ± 10.1 µg/m3, respectively. We estimated that nearly 71.47% of PM10, 79.86% of PM2.5and of 61.25% of PM1in indoor of residential buildings can be removed by negative air ions.
