Particulate matter (PM) emitted from incense burning is a serious problem because of its effects on human health and the environment, especially air quality Southeast Asia. This study investigated PM1 PM2.5 concentrations in two temples Vietnam Taiwan, focusing events (i.e., new moon full day) non-event days using PM sensors. Moreover, samples were collected to determine organic carbon (OC) elemental (EC) concentrations. The (22.7 ± 18.7 36.5 33.9 µg m-3, respectively) lower than those at Taiwan temple (74.5 53.4 97.0 65.4 respectively). activity occurred inside while burner Vietnam's was located outdoors. During event days, about times greater highlighting impact By breaking area into control exposure sites, we found that people experienced 2–5 higher as compared ambient air. PM1/PM2.5 ratio 0.6 0.1 for temple, which value (0.7 0.1). OC EC 129.40 97.68 1.16 2.31 respectively, significantly (OC = 27.70 7.66 1.63 0.93 m-3). Furthermore, OC/EC (20.24) similar reported biomass previous research. increase religious activities major factor leading enhancement pollutant levels surrounding areas. provides valuable information carbonaceous aerosols Asia megacities.
