| Summary: | 碩士 === 嘉南藥理科技大學 === 環境工程與科學系 === 101 === Particulate matter (PM) and polycyclic aromatic hydrocarbons (PAHs) emissions of burning incense have been investigated on the quality of surrounding air. However, the reduction of PM and PAHs from burning incense has received little attention. In the present study, two types of incense were made in the laboratory. Five to thirty percent of Oyster (OS) and Asiatic Clam Shells (ACS) was added to Sin-shan, Lao-shan, Liao and Chen wood flours, which are popular incense materials. Experimental results indicate that the reduction of emissions of PM and PAHs from burning incense increased with increasing amount of OS and ACS additive. Mean PM reductions for 30.0% of OS and ACS were 35% and 34%, respectively. Mean PAH reductions were 21% and 20% for particle-phase PAHs, respectively, and 37% and 21% for benzo[a]pyrene equivalent concentration, respectively. These results may be attributed to OS and ACS acted as filler in the burning incense. OS and ACS was substituted for organic material in the incense reducing PM and PAHs emissions from the smolder. The findings of this study may serve as a guide to producing safer and less-polluting incense.
