本研究在小型燃燒測試系統，燃燒不同合成除蟲菊組成的蚊香燃燒所產生不同粒徑微粒的多環芳香烴排放特性。使用GC/MS定性與定量多環芳香烴。
研究結果顯示4種蚊香燃燒所產生總懸浮微粒質量與總多環芳香烴排放因子有顯著的差異，4種蚊香燃燒所產生的總懸浮微粒質量排放因子範圍為31.0– 70.3 mg/g，其所負載的總多環芳香烴排放因子範圍為2791.1 – 7566.4 ng/g。4種蚊香燃煙微粒的幾何平均值為0.21 µm，且隨總微粒質量排放因子的增加，微粒的幾何平均粒徑呈現增加趨勢。微粒負載多環芳香烴的排放率和排放因子，主要分布在小於0.25 µm和0.25 – 0.5 µm的粒徑。另外，在16種多環芳香烴中以3環(Fluoranthene、Phenanthrene和Pyrene)的佔大多數；Benzo[a]pyrene、Benzo[a]anthracene、chrysene和Dibenzo[a,h]anthracene貢獻89.5 – 91.4 %的總多環芳香烴相當於BaP致癌潛力排放因子。
根據蚊香燃燒所產生的不同粒徑微粒負載多環芳香烴排放特性，我們建議使用含0.015 %美特寧的微煙蚊香，可以有效量減少蚊香燃燒所產生的總微粒質量與多環芳香烴排放量，可作為國內製蚊香產業發展低污染拜香的參考。

This study investigates polycyclic aromatic hydrocarbons emissionin particles of various sizes generated from smoldering different mosquito coils with different synthetic pyrethroid in a combustion test system. The PAHs content was quantified by gas chromatography/mass spectrometry.
Among the four brands of mosquito coil investigated, yielding the emission factor ranges for total particulate mass and PAHs were 31.0–70.3 mg/g and 2791.1–7566.4 ng/g, respectively. The particle and PAHs emission factors varied significantly, respectively. The average of geometric mean diameter (GMD) of particles for tested mosquito coil smoke was 0.21 µm. Total particle mass emission factors increasing upon increasing the GMD of particles. Total particle PAH and mass emission rates and factors were mainly < 0.25 µm and 0.25–0.5 µm in size. The emissions of three-ring PAHs predominated and the major species among the 16 PAHs were fluoranthene, phenanthrene and pyrene for most incense types. The benzo[a]pyrene, benzo[a]anthracene, chrysene, and dibenzo[a,h]anthracene accounted for 89.5–91.4% of the totaltoxic equivalency emission factor.
Based on information of particle PAH emissions for tested mosquito coils, we suggest that smoldering a very low-smoke mosquito coil with 0.015 % of metofluthrin to minimize production of total PAH emission factors for total particles.
