Impact Pathway Approach, to estimate the health impacts and external costs caused by air pollutants in Kaoshiung-Pingtung Metropolitan Area from 2007 to 2009. Based on the information collected by the air pollution monitoring stations of Environment Protection Administration, the concentrations of the target pollutants, ie. SO2, O3 and PM10, were selected of three kinds. An Ordinary Kriging Method of GIS(Geographic Information System) was employed to estimate the average amounts of exposure per year of air pollutants in each district of Kaoshiung-Pingtung Metropolitan Area . 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 Sanmin in 2008, which contributed annually 33.83 YOLLS and 12.8 cases for the acute mortality and the respiratory hospital admission, respectively. For O3, the highest ones were estimated as 144.29 YOLLS and 175.12 cases for acute mortality and respiratory hospital admission, respectively, and occurred in Sanmin in 2008. For PM10, the estimated values were 87.03 YOLLS and 60.65 cases for acute mortality and respiratory hospital admission, respectively, and occurred in Sanmin in 2008. Therefore, it could conclude that the residents who live in Sanmin, Cianjhen, Siaogang, Fongshan and Pingtung districts took high risks in the study periods. The simulation of damage costs, the highest damage cost is estimated as 642 million NTD caused by SO2 in 2007, the aspect of city and county, Kaohsiung City is based on the maximum 326 million in 2007. For O3, the highest cost is estimated as 3612 million NTD in 2008, the aspect of city and county, Kaohsiung City is based on the maximum 1521 million in 2008. For PM10, the highest cost is estimated as 2049 million NTD in 2009, the aspect of city and county, Kaohsiung City is based on the maximum 891 million in 2008. In the aspect of unit damage costs, the estimated outcome shows that SO2 caused the most in 2007, which was 146.42 NTD/Kg; and PM10 also caused the most in 2008, which was 114.82 NTD/Kg.
