中文摘要	本計畫以PTR-MS質譜(包括TOFMS、QMS)針對台塑六輕工業區從南至北選定3個停駐點進行監測(各點至少一週之VOC監測)，初步掌握台塑廠區之周界空氣可能存在之化學物質。本計畫依監測先後分別完成南門宿舍(6/26 – 7/13)、勝高晶圓廠(7/20 – 8/3)及塑化OL-1保養廠(8/10 – 8/31)三處測點依序完成監測任務。透過運作成熟、流暢之資料處理方法與鑑定流程，針對南門宿舍周界分析出11種化學物質，勝高晶圓分析出15種化學物質，塑化OL-1保養廠分析出17種化學物質，包括含氧(醇、醛、酮、酸、酯)、非甲烷碳氫(烯、芳香烴)、含氮物質。依據半定量監測結果，烯類以丙烯 (max: 460.1 ppb)、丁烯 (max: 64.7 ppb)、戊烯 (max: 11.5 ppb)、丁二烯 (max: 59.5 ppb)為主；芳香烴以苯 (max: 92.2 ppb)、C2-芳香烴 (max: 28.7 ppb)、苯乙烯 (26.7 ppb)、C3-芳香烴 (max: 64.5 ppb)為主；含氮VOC成份(NVOCs)為二甲基甲醯胺 (max: 154.6 ppb)、碼啉 (max: 38.7 ppb)為主；含氧VOC (OVOCs)主要有乙醛 (max 44.6 ppb)、丙酮/丙醛 (max: 54.5 ppb)、乙酸甲酯 (max: 315.4 ppb)為主。塑化OL-1保養廠因四周圍繞較多元的製程環境，偵測到VOC物種也最多，偵測出與塑化產業相關之甲基丙烯酸甲酯原料(max: 0.9 ppb)。由於工業區幅員廣大，污染排放源不易判斷，目前確定濃度的趨勢變化與風向之關係性高；南門宿舍測點在大部分時段盛行海風，來自海洋乾淨之空氣的化學物質測值偏低；勝高晶圓測點在盛行海風時(面相廠區)，多數化學物質不減反增；塑化OL-1保養廠污染物因更接近製程，汙染組成與變化更為複雜，當氣象些微的風向轉變，即造成濃度明顯差異，因此監測數據配合氣象資料分析，使用高解析TOFMS偵測，配合on-line GC同步分析的佐證，能快速掌握工業區內之潛在排放物質。在為期2個月的監測期間，所量測到的化學物質濃度均在ppb的範圍，部分濃度偏高之物質其濃度亦不超過1 ppm，因測點皆位於廠區內，緊鄰製程，因此初步認為ppb濃度範圍應屬於正常製程操作情況下的合理排放量，而此次獲得的物質清單可作為日後出現預警防災需求時的基線參考資料。

摘要	This project is to conduct PTR-MS measurements of volatile organic compounds (VOCs) within the Formosa Naphtha No.6 industrial park, which is different from the previous relevant NIEA projects that were conducted around and outside the park. Three sites (P1, P2 and P3) were chosen including: 1. south of the employee dormitory (6/26 – 7/13, P1); 2. Formosa Sumco Technology (7/20 – 8/3, P2); 3. Oil refinery-1 (8/10 – 8/31, P3), where real-time measurements were lasted for at least two weeks at each site. PTR-TOF has a major advantage of greater mass resolution than does QMS. It can perform rapid scans of air matrix and detect air-borne compounds released from potential sources. During the three monitoring periods, of all the compounds detected by PTR-TOF, their mixing ratios were in the range of several ppb (v/v) to several hundred ppb. Based on the observed concentration ranges, no major leaks existed considering the scale and complexity of the park. The measurement results suggest that 11 VOCs were detected at P1, 15 compounds at P2 and 17 compounds at P3. These found VOCs mainly comprised of oxygenated VOCs (alcohol, aldehydes, ketones, organic acids, esters), non-methane hydrocarbons (alkene, aromatics), nitrogen-containing VOCs and sulfur-containing VOCs. When summarizing the semi-quantitative results obtained by PTR-TOF at the three sites, major constituting VOCs in ambient air are categorized as follows: Alkenes including ethene (460.1 ppb), butenes (64.7 ppb), pentenes (11.5 ppb), butadienes (59.5 ppb). Aromatics included benzene (92.2 ppb), C2-benzene (28.7 ppb), styrene (26.7 ppb), and C3-benzene (64.5 ppb). The N-containing VOCs included N,N-dimethylformamide (154.6 ppb), morpholine (38.7 ppb). O-containing VOCs included acetaldehyde (44.6 ppb) and acetone/propanal (54.5 ppb). Furthermore, there were two compounds of trace levels, namely formic acid (7.2 ppb) and methyl methacrylate (0.9 ppb), which were only observed at P3. These aforementioned compounds will form a useful list of reference to be adopted in future forensic investigation in case of industrial hazards. We found that most observed VOCs were sensitive to the change of wind direction, which is reasonable as the sources of high variety were in proximity to the monitoring site. A common feature would be pronounced concentration spikes (such as for propylene) during the course of real-time monitoring. The measurement data of PTR-TOF were able to be compared with those of QMS at P1 to assure the data quality of TOFMS. Consistent results were noted between the two instruments, which suggests the reliability of TOFMS measurements for most VOCs. An automated gas chromatograph (GC) was employed to assist the validation of measurements of TOFMS at P2 and P3 when QMS malfunctioned and was not available for mutual validation. As a result, a rugged and simple GC can be useful to compliment the more fragile and delicate instruments such as PTR-MS in field measurements.
