Abstract

In this study, we estimated nitrogen dioxide (NO2) concentrations in microenvironments where residentialindoor, residential outdoor, other indoors, and transportation using measured personal exposure and multiplelinear regression analysis of time-weighted average model, and compared with measured NO2 concentration inmicroenvironments. Measured residential indoor, outdoor and other indoor NO2 concentration was 22.22±9.59ppb, 23.64±9.62 ppb, and 22.07±13.90 ppb, respectively. NO2 concentrations in residential indoor and outdoor,total outdoor, other indoor, and transportation by multiple regression analysis were significantly estimated as20.48 ppb, 32.79 ppb, 24.35 ppb, and 28.82 ppb, respectively (p= 0.000). Measured and estimated NO2concentration were similar with each other, therefore NO2 concentrations in each microenvironment were able tobe estimated using time-weighted average model and personal exposure with multiple regression analysis.
