| Summary: | 碩士 === 朝陽科技大學 === 環境工程與管理系碩士班 === 95 === This study utilized the impact pathway approach (IPA) to estimate the health impacts and external costs caused by the air pollutants from 2002 to 2005. Combining with the ordinary kriging of Geographic Information System (GIS), a quantitative method is developed based on the monitoring data of Taiwan Environmental Protection Administration to represent the levels of air pollutions, which were exposed by the local residents. The health impacts were estimated through the selected dose-response functions and a monetary transfer approach based on the European data was conducted to value local damage costs caused by air pollutants.
The results indicate that the highest health impacts of SO2 occurred in Changhua in 2005, which contributed 17.6 YOLLS/year and 6.7 cases/year for acute mortality and respiratory hospital admission, respectively. For O3, the highest ones were estimated as 68 YOLLS/year and 41 cases/year for acute mortality and respiratory hospital admission, respectively, that occurred in Beitun in 2003. For PM10, the estimated values were 50 YOLLS/year and 35 cases/year for acute mortality and respiratory hospital admission, respectively, that occurred in Changhua in 2004. Therefore, it could conclude that the residents who live in Changhua, Fongyuan and Dali districts took high risks in the study periods.
The simulation of damage costs and unit damage costs were also conducted. The highest damage cost is estimated as 970 million NTD caused by SO2 in 2005. It converted to the unit damage costs as 29 NTD/kg SO2. For O3, the highest cost is estimated as 554 million NTD in 2004. For PM10, the highest cost is estimated as 345 million NTD in 2004. It converted to the unit damage cost of 80 NTD/kg PM10.
