　　本研究進行臺灣南部地區五座石化工業廢棄物焚化爐煙道廢氣中多環芳香烴化合物（Polycyclic Aromatic Hydrocarbons, 一般簡稱PAHs）之調查研究，並評估這五座焚化爐相關空氣污染防治設備對PAHs之去除效率。其目的為建立基本資料，做為往後PAHs排放總量之推估、擴散模式之模擬、排放標準之擬定及未來排放量消減策略研擬之重要資訊。煙道廢氣粒狀物相及氣相PAHs之採集，擬以一套等速抽引採樣系紁為之。二十一種個別PAHs則以氣相層析質譜儀（GC/MS）分析之。
　　本研究之成果包括下列四項：1. 在石化廠焚化爐A、B 、C、D與E所排之煙道廢氣總PAHs濃度平均值分別為216、145、981、971與286ug/Nm3，且其煙道廢氣PAHs採樣系統收集到之PAH質量分怖，皆以氣相所佔百分比最高，分別為95.3%、78.0%、96.2%、93.9%與64.4%。在本研究所檢測之四座污泥焚化爐中，其煙道廢氣之PAHs皆以低分子量Nap與PA濃度最高，此兩種PAHs，或可視為本類型焚化爐排放廢氣中PAHs之指標。2. 五座焚化爐總PAHs之質量排放百分比，平均煙道廢氣佔95.4%，旋風集塵器佔0.56%，靜電集塵器佔0.03%，溼式靜電集塵器佔0.25%，溼式洗滌塔佔4.38%，爐床底灰佔0.10%。顯示大部分之PAHs係由煙道廢氣至環境中，故欲有效防止PAHs對人類造成危害，應對煙道廢氣加強探制。3. 五座石化工業廢棄物焚化爐之空氣污染探制設備，對總PAHs之去除率介於0.03% ~ 8.96%，平均為2.28%。故以上各空氣污染探制設備對以氣相為主之PAHs，皆無法達到有效之控制。4. 焚化爐A、B 、C、D與E自煙道排放總PAHs之排係數分別為2.35、1.16、10.3、30.9與36.1 mg/Kg-Sludge。而BaP自煙道排放之排放係數則介于5.59~2480 u g/Kg-Sludge之間，平均為718ug/Kg-Sludge。

　　This study investigates the emission of Polycyclic Aromatic Hydrocarbons (PAHs) from the stack flue-gas of the five petrochemistry industrial waste incinerators in southern Taiwan. In addition, the collection efficiencies of PAHs by the air pollution control devices are also investigated. The objective of this study is to set up the data bank for the calculation of total amout of PAH emission, the PAH dispersion modeling, and the assessment of cancer risk of PAH emits from the petrochemical industrial waste incinerators. The PAH samples from the stack flue-gas are collected isokeneticly by a PAH stack-sampling system. Twenty one individual PAHs are anaalyzed primarily by a gas chromatography/ mass spectrometer(GC/MS).
　　The major results of this study primarily includes the following items:(1)The mean concentration of total PAHs in the stack flue-gas of this five petrochemistry industrial waste incinerators are between 145 and 981 ug/Nm3 and averaged 520 ug/Nm3. (2)The mean total PAH mass emission distribution from stack flug-gas 、cyclone、EP、wet EP.wet EP.wet scrubber and bottom ash for these five petrochemistry industrial waste incinerators in 95.4%、0.56%、0.03%、0.25%、4.38% and 0.10%, respectively. (3)The total PAHs collection efficiencies of the air pollution control dvices in these five petrochemistry industrial waste incinerators are between 0.03% ~ 8.96 %, and averaged 2.28%. The air pollutio control devices of this five petrochemistry industrial waste incinerators can not remove PAHs effectively, which are mostly in the gas phase. (4)The total PAHs emission factors of this five petrochemistry industrialk waste incinerators are 2.37、1.28、10.9、31.0 and 38.4 mg/Kg-waste, respectively. The BaP emission factors are between 6.34 ~ 2690μg/Kg-waste, and averaged 772μg/Kg-waste.
