| Summary: | 碩士 === 國立成功大學 === 環境工程學系碩博士班 === 95 === A combustion chamber study was conducted for four types of joss papers and five types of incenses. Solid and gas phase pollutants from each burned joss paper and incense were quantitatively collected with a micro-orifice uniform deposited impactor (MOUDI) and gaseous pollutant (NOx, SO2, and CO) analyzers, respectively. VOC were detected by a GC-MS. The metallic contents in fly ash of joss papers and incenses were analyzed by an inductively coupled plasma optical emission spectrometry (ICP-OES). Besides, proximate analysis, elemental analysis and metallic analysis in raw material joss papers and incenses were also performed.
The concentrations of NOx, SO2 and CO from burning joss papers and incenses were higher than the standards of indoor air quality (IAQ). The VOC analysis found that the major components were benzene and toluene. They may endanger human’s health. The particulate generation from burning joss papers were ranged from 28.8 mg/g to 40.8 mg/g. The size distributions of particulates were concentrated between 0.56 μm and 3.2 μm; the size distributions of particulates from burning incenses were concentrated between 0.18 μm and 0.56 μm.
When burning joss papers and incenses, most metals exist in the bottom ash. It was found that all Zn and Mg were in the bottom ash of joss papers and most Pb was in the fly ash of incenses.
There are more than 34,920 tons joss papers and 4,910 tons incense burned at from the temples in Taiwan every year. Emissions evaluation of air pollutants from joss paper and incense burning may be estimated as follows: joss paper: 67.0 tons NOx, 1.05 tons SO2, 1,158 tons CO, and 1,207 tons particulates. Incense: 15 tons NOx, 0.81 tons SO2, 1,592 tons CO, and 71 tons particulates.
