本年度針對台北新店垃圾焚化廠、台中后里垃圾焚化廠及高雄市南區垃圾焚化廠進行周界介質採樣分析作業。由調查結果顯示，(1)台北新店廠周界空氣、土壤及植物中戴奧辛總毒性當量平均別為0.046 pg I-TEQ/m3、13.6 ng I-TEQ/kg d.w及2.59 pg I-TEQ/g d.w. (2)台中后里廠周界空氣、土壤及植物中戴奧辛總毒性當量平均別為0.045 pg I-TEQ/m3、7.51 ng I-TEQ/kg d.w及2.58 pg I-TEQ/g d.w (3)高雄市南區廠周界空氣、土壤及植物中戴奧辛總毒性當量平均別為0.120 pg I-TEQ/m3、3.36 ng I-TEQ/kg d.w及3.89 pg I-TEQ/g d.w。 由本計畫所得數據配合該地特定污染源煙道排放戴奧辛congener pattern 進行PCA及Cluster分析，可充分解釋採樣點空氣中戴奧辛來源，各廠所解析之主成份 Factor 1都具有90%以上的變異量。歸納結果顯示，台北新店廠、台中后里廠及高雄市南區廠週遭環境並不受焚化爐太大之影響。 另外，本計畫彙整環保署歷年計畫(89年至96年)各焚化廠周邊地區特定採樣點之空氣、土壤與榕樹葉中戴奧辛數據，經由Mann-Kendall Trend Test 顯示並無隨時間有統計上明顯上升或下降趨勢，可知國內大型垃圾焚化廠運作對於週遭環境並無顯著的影響。整體而言，環保署自86年起針對國內固定污染源戴奧辛排放進行管制及訂定排放標準有一定的成效。

The main objective of this study is to investigate the total dioxin toxicity equivalency quotients (TEQs) of PCDD/Fs in the multi-media of the area around three large municipal solid waste incineration (MSWI) facilities; i.e., Hsingden Plant, Houli Plant, and Kaoshung City Southern District Plant. The results show that the mean dioxin TEQs of the ambient air, soils, and vegetations around the Hsingden plant were 0.046 pg I-TEQ/m3, 13.6 ng I-TEQ/kg d.w., and 2.59 pg I-TEQ/g d.w., respectively. In the case of the area around the Houli plant, the dioxin TEQs were 0.045 pg I-TEQ/m3, 7.51 ng I-TEQ/kg d.w., and 2.58 pg I-TEQ/g d.w. in the ambient air, soils, and vegetations, respectively. For the area around the Kaoshung City Southern District Plant, the dioxin TEQs of the ambient air, soils, and vegetations were determined to be 0.120 pg I-TEQ/m3, 3.36 ng I-TEQ/kg d.w., and 3.89 pg I-TEQ/g d.w., respectively. The possible emission sources of PCDD/Fs at each sampling site were further investigated by carrying out PCA and Cluster analysis using data collected from this study and the dioxin congener pattern established from local stack emission database. It was found that, for a given tested facility, the variation of PC1 (Principal Factor 1) was above 90%. Therefore, the operations of the three investigated MSWI facilities are unlikly the major sources of the dioxin to their surrounding area. In addition, this project reviewed and analyzed the data collected from previous similar studies conducted by Taiwan’s EPA from 2000-2007. According to the results from Mann-Kendall Trend test, neither increasing nor decreasing trend was statistically observed on the concentrations of PCDD/Fs in the ambient air, soils, and tree leaves of each sampling site. Therefore, it can be concluded that the operations of large MSWI facilities in Taiwan did not observably affect the concentrations of PCDD/Fs in the surrounding environments. In summary, the dioxin emission regulations for specific industries implemented by Taiwan’s EPA since 1997 have effectively controlled the emissions of PCDD/Fs from various incineration/combustion processes.
