| Summary: | 碩士 === 嘉南藥理大學 === 環境工程與科學系 === 103 === Most temple in Tainan, Taiwan, resulting in the air pollutants emission of burning incense to affecting air quality. This study selected twelve kinds of Tainan commercially available incense. Origin, manufacturing methods, and whether has National Standards of the Republic of China(CNS) certification, as the distinction between types of incense. the air sampler to collected the whole amount particulate air pollutants emission of burning incense. First calculate incense burning particulate matter(PM) emission factor of the generated, and then the chemical analysis to PAHs. Finally simulate different operating conditions and exposure scenarios burning incense the recommended amount of assessments, and provide the public with low health hazard screening methods of incense.
The results showed that twelve kinds of commercially available incense its origin, manufacturing methods, and whether has CNS certification, in regard to the air pollutants emission of burning incense , there is no significant difference. In addition, select a incense to has higher rate of emissions of air pollutants. In a small space and the relatively poor ventilation rate conditions, just burning one incense that would make indoor air quality exceeded the standard (PM2.5，35 µg/m3-24hr). And the non-cancer risk (hazard quotients 1.0) and cancer risk (to work 25 years with exposure to calculation of risk value <10-6) both greater the reference value. If select a incense to has low of emissions of air pollutants. In the larger space and better ventilation rate, burning 2646 incense still in line with indoor air quality standards. In terms of non-carcinogenic and carcinogenic risk estimates which can ignite respectively 3.5x106 and 16 incense.
In some of the general's home temple. Although it is not the state of prolonged continuous exposure. Due to space restrictions, via a mode estimate. At high ventilation rate (7Ach) condition, burning low pollution incense, and PM2.5 standard values for comparison only allowed one, and carcinogenic only one would be in excess to the value risk, non-cancer risk can be simultaneously ignited 14 support incense.
After burning incense of the same weight, generated to the more ash quality and PM would be less. The ash stay longer the length, the PM emission would be less. This result can provide the public with easy judgment to low health hazard screening methods of incense. In this study, in order to safeguard public health as a benchmark. Burning incense number of recommendations discussed by the preliminary. Will be as an environmental protection authority control the temple and at home temple to incense burning the number of reference.
