中文摘要	本計畫執行高雄市政府環境保護局之高雄市戴奧辛監測及管理計畫，主要工作內容為進行稽查檢測戴奧辛排放源煙囪三十五根次和重金屬十五根次、進行戴奧辛污染源稽巡查作業、進行環境監測介質包括污染源周界空氣、土壤與植物戴奧辛調查、進行戴奧辛暴露及健康風險評估作業且建議戴奧辛管制策略、進行戴奧辛減量輔導及技術轉移訓練、進行固定污染源空氣污染防治設備處理效率評估等。本計畫煙道戴奧辛稽查檢測工作中，除都市垃圾焚化爐MSWI1-D1和事業廢棄物焚化爐IWI5-D之戴奧辛濃度分別為0.369 及0.112 ng I-TEQ/Nm3，超過法規標準外，其餘廠家檢測結果皆符合法規標準。高雄市99年PCDD/Fs年排放總量為5.57 g I-TEQ/yr，各類污染源佔總貢獻量分別為大型都市垃圾焚化爐(5.55%)、中小型焚化爐(0.0530%)、事業廢棄物焚化爐(4.30%)、醫療焚化爐(0.114%)、煉焦爐(1.55%)、水泥窯代處理廢棄物(0.170%)、燒結爐(77.8 %)、集塵灰熱回收(0.231%)、電弧爐(6.00%)、火化場(2.98%)、鍋爐發電(0.00493%)、鋁二級冶煉廠(0.911%)、鋅二級冶煉廠(0.0433%)及銅二級冶煉廠(0.294%)。本計畫煙道重金屬污染源抽測作業中，除一般事業廢棄物焚化爐IWI1-H1和IWI1-H2之汞濃度分別為0.126和0.139 mg/Nm3，超過法規標準值(0.1 mg/Nm3)，其餘廠家檢測結果皆符合法規標準值。高雄市區周界大氣採樣點總I-TEQ濃度介於0.0267~ 0.0917 pg I-TEQ/Nm3之間，總I-TEQ濃度平均值為0.0456 pg I-TEQ/Nm3，周界植物採樣點總I-TEQ含量介於0.832~3.21 ng I-TEQ/kg之間，總I-TEQ含量平均值為2.14 ng I-TEQ/kg，周界土壤採樣點總I-TEQ含量介於0.181~ 8.19 ng I-TEQ/kg之間，總I-TEQ含量平均值為2.03 ng I-TEQ/kg。由高雄市周界環境介質之等位濃度軌跡圖，可知位於小港區之PCDD/Fs採樣點濃度較高，推測高雄市小港區環境介質中PCDD/Fs濃度受到電弧爐及燒結爐等固定污染源之影響。利用AERMOD所模擬的濃度結果，結合環境多介質傳輸模式，計算各區居民所承受的健康風險值，由結果指出致癌風險最高點落在小港區內，風險向西北遞減，而分佈越近污染源的地區則危害越高，其中致癌或是非致癌風險主要的暴露途徑為直接呼吸吸入。計畫中所檢測之污染源來看，主要的污染源為中國鋼鐵股份有限公司燒結廠、台灣電力股份有限公司大林發電廠及高雄市政府環境保護局南區資源回收廠此三個污染源，其對於高雄市大部分之行政區皆為主要的風險貢獻者。而對於位於高雄市較北邊的楠梓區與左營區，主要的污染則為晉緯工程股份有限公司。本計畫針對高雄市4處固定污染源場所進行廢氣處理設備前後之戴奧辛及重金屬採樣分析。中國鋼鐵、國鉅環保、海光及龍慶公司之袋式集塵器對總PCDD/Fs去除率分別為96.7~97.5%、92.2~94.9%、32.3~97.8%、-13.3~51.9%；中國鋼鐵和國鉅環保公司之袋式集塵器對重金屬鉛、鎘、汞和砷具有良好控制效率，海光及龍慶之袋式集塵器分別對重金屬砷及汞之去除率偏低；其中龍慶主要因袋式集塵器之記憶效應而造成去除效率降低。

摘要	This project investigated the emission of dioxin sampled from stationary sources in Kaohsiung city. Major works included the emission source sampling of dioxin and heavy metals, the emission source inquiry of dioxin, the analyses of ambient environment (air‚ leaves and soil), risk assessment, the technical assistance of reducing dioxin, and the efficiency assessment of air pollution control device (APCD). The mean total PCDD/Fs concentrations of stationary sources MSWI1-D1 and IWI5-D were 0.369 and 0.112 ng I-TEQ/Nm3, respectively. The values are higher than the regulation limit of Taiwan EPA. The emissions of PCDD/Fs from other stationary sources are lower than the regulation limit of Taiwan EPA. The estimated total annual emission of PCDD/Fs from these emission sources in Kaohsiung city was 5.57 g I-TEQ/yr (large-scale MSWIs, 5.55%; small-scale MSWIs, 0.0530%; industrial waste incinerators, 4.30%; medical waste incinerators, 0.114%; coke oven planes, 1.55%; cement kilns, 0.170%; sinter planes, 77.8 %; RHF, 0.231%; electricfurnaces, 6.00%, crematorium 2.98%; boiler electricity generation, 0.00493%; secondary aluminum smelters, 0.911%; secondary zinc smelters, 0.0433%; secondary copper smelters, 0.294%). The existing emission sources of heavy metals were surveyed. The concentrations of Hg for IWI1-H1 and IWI1-H2 were 0.126 and 0.139 mg/Nm3, respectively. The values are higher than the regulation limit of Taiwan EPA (0.1 mg/Nm3). The emissions of heavy metals from other stationary sources are lower than the regulation limit of Taiwan EPA. The total PCDD/F concentrations of ambient air, leaves and soil were 0.0267-0.0917 pg I-TEQ/Nm3, 0.832-3.21 ng I-TEQ/kg and 0.181-8.19 ng I-TEQ/kg, respectively. The mean PCDD/F concentrations of ambient air, leaves and soil were 0.0456 pg I-TEQ/Nm3, 2.14 ng I-TEQ/kg and 2.03 ng I-TEQ/kg, respectively. A maximum PCDD/Fs concentration in Siaogang district was carried out. The dominant contributions of PCDD/Fs concentration in Siaogang district were electricfurnaces and sinter planes. AERMOD and multimedia transport modeling were used to estimate the health risks of the residents in Kaohsiung city. The maximum cancer risk of a resident living in Siaogang district was found. The risk harm is high when the district nears to pollution source. The inhalation was the main exposure route for carcinogenicity and non-carcinogenicity risks. Major emission contributors for most districts are SINTER, PP and MSWI1. IWI6 was major pollution source for Nanzi and Zuoying districts. This project inverstigated the concentrations of PCDD/Fs and heavy metals at the inlets and outlets of the bag filter in four stationary emission sources. Removal efficiencies of PCDD/Fs by bag filters in ChinaSteel, Kuo-Chu, Hai-Kwang and Lung-Ching were 96.7-97.5%、92.2-94.9%、32.3-97.8%、-13.3-51.9%, respectively. The bag filters of ChinaSteel and Kuo-Chu have good control efficiencies for Pb, Cd, Hg, and As. The bag filters of Hai-Kwang and Lung-Ching have low efficiencies for the removal of As and Hg. Low removal efficiency of heavy metals for Lung-Ching was due to memery effect of bag filter.
