| Summary: | 碩士 === 東海大學 === 環境科學與工程學系 === 97 === Over the past two decade, many studies have found the association between air pollutant and hospital respiratory and cardiovascular admission. Each study is from different countries, and each country has own distinctive weather, land and human activities. In hence we need more research for Taiwan’s epidemiology, especially in central Taiwan.
Central Taiwan has the highest CO2 emitting power plants in the world, so we set this area to investigate. The impact of season, area and ages may have different influence, therefore, we discussed for four season and separated the central Taiwan for metropolis and suburb. The subjects in the study were classified in five groups: preschooler(0-4 years old), children(5-14 years old), Adults(15-65 years old), Elder(more than 65 years old) and all ages. Hospital admissions for respiratory and cardiovascular and air pollutant data were obtained for the National Health Insurance Research Database (NHIRD) and Taiwan Environmental Protection Administration (TEPA).
Risk of morbidity for five pollutants, there had no positive correlation at metropolis. CO and NO2 had the significant results in four seasons at suburb, O3 had the positive correlation in spring and winter for respiratory and cardiovascular disease. In this study, we compare the Pollutant Standard Index (PSI) and Revised Air Quality Index (RAQI) with Relative Risk (RR). At final results, both of two Index have no significant correlation in metropolis, at suburb, we found the RAQI to hospital admission, the RR was higher than PSI, either season or groups.
