摘要：Constant Injection Method was applied in a full scale air quality experimental chamber to obtain the emission factors (EFs) of PM2.5 and other gaseous pollutants produced from the burning process of disc solid mosquito-repellent incense, electric liquid mosquito-repellent incense and electric mat mosquito-repellent incense, respectively. Results showed that PM2.5 EFs of above three types of mosquito-repellent incense were 10.8 mg/h, 1.1 mg/h, 2.2 mg/h, respectively. The corresponding values of TVOC EFs were 103.4 mg/h, 69.5 mg/h and 58.8 mg/h, respectively. Via implementation of fitting analysis to particle size distribution (PSD) of released particles from disc solid mosquito-repellent incense, it was found that the PSD kept a well self-preservation signature. In addition, the fitting results showed that count median diameter (CMD) was 90 nm, geometric standard deviation (GSD) was 1.65. The emission factors of particle number were obtained via using mass concentration EFs and the corresponding PSD modeling results. In addition, modeling was conducted in a common residential house with air change rate of 2 h-1, each type of mosquito-repellent incense would cause TVOC concentration raising up with a factor of 1.8-3.2 times greater compared to the relative indoor air standards.
