Assessment of Indoor and Ambient Air Pollution at Complex Buildings in Hanoi

Abstract

The most typical air pollutants including PM10, CO, SO2, NOx are monitored at different sites indoor (basement, shopping malls) and outdoor (ambient air) of several complex buildings which are used for different purposes of resident, office, and shopping malls in Hanoi. The results show that the indoor air pollution concentrations tend to be higher than the corresponding pollutants of the ambient air. The results show the highest concentrations are in RC building for the same category of floor comparing to the other two buildings. Pollutant concentrations at basement for parking is the highest with the values of PM10, SO2, NOx, CO of 67.1 ± 21.2 µg/m3, 224.8 ± 34.9 µg/m3, 287.3 ± 136.3 µg/m3, 22,372.5 ± 2,324.5 µg/m3, respectively. The high concentration of indoor air pollutants are harmful for human health, especially for those who have longer exposure time.
 
 
 

Investigation of Indoor and Outdoor Air Quality at Elementary Schools in Hanoi, Vietnam

“…While the effects of IAP on health have been studied extensively in many countries, especially in developed countries, but very limited in Vietnam. There are studies reported about the IAP level in complex building in urban area [16], kitchen room at rural area [17], and traffic mode (public bus) [18]. However, no published to present about air pollution level for indoor classrooms.…”
