本計畫針對電弧爐EAF、鋁二級冶煉廠ALS、火葬場CRE及金爐J1及J2進行煙道廢氣PCDD/Fs與PBDEs之採樣分析，成果如下：1.電弧爐EAF與鋁二級冶煉廠ALS煙道廢氣中總PCDD/Fs I-TEQ濃度分別為0.0413及0.221ng I-TEQ/Nm3，皆符合法規標準規範。排放係數分別為0.416及3.50 μg I-TEQ/ton-feedstock。2.火葬場CRE、金爐J1及J2煙道廢氣中總PCDD/Fs I-TEQ濃度分別為0.139、0.703及0.00681ng I-TEQ/Nm3；排放係數分別為3.83μg I-TEQ/body及0.166、0.00827 μg I-TEQ/kg。本計畫中金爐J2(具有水洗塔設備) (0.00827 μg I-TEQ/kg)較金爐J1(無空污防治設備)之排放係數(0.166 μg I-TEQ/kg)低上許多。3.電弧爐EAF、鋁二級冶煉廠ALS底渣中總PCDD/Fs I-TEQ含量分別為0.0213及0.000493ng I-TEQ/g，而飛灰中總PCDD/Fs I-TEQ含量分別為0.0740及0.0499 ng I-TEQ/g。另外，在金爐爐灰部分，金爐J1及J2爐灰中總PCDD/Fs I-TEQ含量平均分別為0.000457及0.000148ng I-TEQ/g。4.電弧爐EAF與鋁二級冶煉廠ALS煙道廢氣中總PBDEs濃度分別為4.32及34.9 ng/Nm3，排放係數為43.7及551μg/ton-feedstock。5. 火葬場CRE、金爐J1及J2煙道廢氣中總PBDEs濃度分別為35.8、52.3及45.0 ng/Nm3，排放係數為1000 μg/body及12.2、54.2 μg/kg。6.電弧爐EAF與鋁二級冶煉廠ALS底渣中總PBDEs分別為2.15及0.231ng/g，而飛灰中總PBDEs含量為9.59 及57.4ng/g。在金爐爐灰部分，金爐J1及J2 爐灰中總PBDEs含量平均分別為0.438及0.539ng/g。7. 台南縣鋁二級冶煉廠、電弧爐、火葬場及廟宇金爐這四種固定污染源PCDD/Fs之年排放量分別為0.323、0.396、0.0237及2.26 g I-TEQ/yr。若以這四種污染源PCDD/Fs年排放總量來看，其各別佔全部排放量之10.8%、13.2%、0.789%及75.3%；而PBDEs之年排放量則分別為70.5、524、7.24及188.7 g/yr。若以這四種固定污染源年排放總量來看，鋁二級冶煉廠、電弧爐、火葬場及廟宇金爐分別佔全部排放量之8.9%、66.3%、0.92%及23.9%。

One electric arc furnace (EAF), one secondary aluminum smelter (ALS), one crematory and two joss paper furnaces in Tainan County were investigated for their emission of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) and polybrominateddiphenyl ethers (PBDEs). The results are as follows. 1. PCDD/F concentrations in the stack flue gases of the EAF and secondaryALS were 0.0413 and 0.221ng I-TEQ/Nm3, respectively. Their corresponding emission factors were 0.416 and 3.50 μg I-TEQ/ton-feedstock. 2. PCDD/F concentrations in the stack flue gases of the crematory and the two joss paper furnaces were0.139、0.703and 0.00681ng I-TEQ/Nm3, respectively.Their corresponding emission factors were3.83μg I-TEQ/body, and 0.166、0.00827 μg I-TEQ/kg. The joss paper furnace with one wet scrubber as air pollution control device possessed a much lower emission factor (0.00827 μg I-TEQ/kg). 3.PBDE concentrations in the stack flue gases of the EAF and secondary ALS were 35.8, 52.3 and 45.0 ng/Nm3, respectively.Their corresponding emission factors were 43.7 and 551μg I-TEQ/ton-feedstock. 4. PBDE concentrations in the stack flue gases of the crematory and the two joss paper furnaces were 0.139、0.703and 0.00681ng I-TEQ/Nm3, respectively. Their corresponding emission factors were 1000 μg/body, 12.2 and 54.2 μg/kg. 5. Annual PCDD/F emission quantities from secondary ALS, EAF, crematory and the joss paper furnaces were 0.323、0.396、0.0237 and 2.26 g I-TEQ/yr, respectively. 6. Annual PBDE emission quantities from secondary ALS, EAF, crematory and the joss paper furnaces were 70.5、524、7.24及188.7 g/yr, respectively.
