Abstract
This study identified the differences among 5 typical dwelling types in Ho Chi Minh City
(HCMC) about the risk of indoor air pollutants accumulation (as explained in another paper
[1]). Based on data collected from questionnaire, diary of occupants living in 100 houses, we
organized a decision scheme evaluating the Risk of Indoor Air Pollutants accumulation for the
Kitchen (RIAP-K) ranging from “high” to “low”. The risk in the living space depends on the
connection between the kitchen and the living room. So we continue to evaluate the risk for the
living family space (RIAP-L) also ranging from “high” to “low”. Among the five house types,
rental house presents the highest RIAP-L. Concentrations of carbon dioxide (CO2), carbon
monoxide (CO), fine particles (PM2.5) and humidity level during cooking confirm the difference
between ‘low’ and ‘high’ RIAP-L groups in these houses.
