First I analyzed the risk distributions of these two facilities inside their impact zones. And then I provided the comparison results among four risk-exposed groups ( farmer, adult in general, farmer’s child, child in general), particularly the similarities and difference between two power plants.he results show that gross risk of having cancer between two neighborhood areas with coal-fired power plants are below 10-6, and the hazard quotients are less than 1.0. And the risk for the health of people in the neighborhood is not necessarily related to the size of the generators at the coal-fired power plants. Also, the risk of health was deeply affected via the way people live and make living in the neighborhoods, in other words, the type of industry in the community, (ex. agriculture and fishery).中文摘要……………………………………………………………………… I文摘要……………………………………………………………………… II錄…………………………………………………………………………… III目錄………………………………………………………………………… IV目錄………………………………………………………………………… V1章 緒論………………………………………………………………… 1-1.1 前言…………………………………………………………………. 1-1.2 研究目的……………………………………………………………. 1-22章 文獻回顧…………………………………………………………… 2-1.1 火力發電方式與燃煤組成份介紹…………………………………. 2-1.2 台灣戴奧辛與重金屬排放與管制現況…………………………..... 2-4.3 實地多介質風險評估……………………………………………..... 2-12.4 實地風險評估物質危害資料………………………………………. 2-14.5 其他燃煤電廠曾執行之健康風險評估案例………………………. 2-223章 研究方法…………………………………………………………… 3-1 3.1 大氣擴散模式………………………………………………………. 3-4 3.2 地理資訊系統………………………………………………………. 3-8 3.3 環境多介質模式—多介質傳輸轉換及多途徑暴露評估…………. 3-9 3.4 環境多介質模式—劑量效應評估…………………………………. 3-22 3.5 環境多介質模式—風險量化………………………………………. 3-254章 結果與討論………………………………………………………….. 4-1 4.1 執行風險評估所需蒐集與前處理之各項輸入參數與假設………. 4-1 4.2 台中電廠之健康風險分析結果……………………………………. 4-18 4.3 興達電廠之健康風險分析結果……….…………………………… 4-45 4.4 兩座電廠的研究結果比較與探討…….…………………………… 4-735章 結論與建議…………………………….……………………………. 5-1 5.1 結論…………………………………….…………………………… 5-1 5.2 建議……………………………………….………………………… 5-1考文獻……………………………………………………………………… VIIapplication/pdf3277107 bytesapplication/pdfen-US戴奧辛重金屬風險評估燃煤電廠DioxinsHeavy MetalsRisk AssessmentCoal-fired Power Plant[SDGs]SDG3thesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/181620/1/ntu-98-P95541203-1.pdf
