Abstract Combustion of incense, candles, and mosquito coils produces a variety of air pollutants, which may cause adverse health effects. This study was to characterize emissions of particulate matter (PM 2.5 ) and carbon monoxide (CO) from the burning process of three selected types of emitters: incense, candles, and mosquito coils. The experiments were conducted in an aluminum foil-lined wall chamber with a dimension of 1x1x1 m 3 . Emission rates and emission factors of the test emitters were obtained from fitting time-dependent concentrations of the measured pollutants to a single-compartment mass balance model. The emission rates and emission factors of incense combustion were: PM 2.5 154-255 mg/h and 65.6-252 mg/g; CO 378-790 mg/h and 242-454 mg/g. The emission rates and emission factors of mosquito coil combustion were: PM 2.5 266-1611 mg/h and 112-184 mg/g; CO 722-837 mg/h and 82.4-368 mg/g. The emission rates and emission factors of candle combustion were: PM 2.5 8.80-9.97 mg/h and 1.87-2.17 mg/g; CO 74.7-76.8 mg/h and 14.2-18.4 mg/g. The emission rates and emission factors of PM 2.5 and CO for the test incense and mosquito coils were of similar magnitude, but they were approximately 1-2 orders of magnitude higher than those for the test candles. The reason could be due to the fact that incense and mosquito coils are produced purposely to combust incompletely for a smoldering effect. The simulation for the impacts of burning of the combustible household products on occupant exposure shows that the increased ventilation rate of a room is suggested to reduce health risks of customers exposed to the released air pollutants.
