中文摘要	本計畫主要為開發周界中N-甲基咯酮(NMP)、異丁醇(IBA)、乙二醇(EG)、二乙醇胺(DEA)和醋酸(HAc)等5項空氣污染物檢測技術，提供行政院環保署環境檢驗所建立標準方法之依據。研究方法乃參考去年度執行排放管道N-甲基咯酮等化合物之經驗，開發上述5項成分之周界檢測方法。由於5項空氣污染物的特性不一，其中沸點範圍(108~270 ℃)與飽和蒸氣壓(15.7~0.00014 mmHg) 差異頗大，而且N-甲基咯酮、乙二醇與二乙醇胺具有黏稠性，因此，幾經測試與驗證後，主要將5項目標化合物規劃為吸附和吸收兩類調查技術開發。其中，N-甲基咯酮、異丁醇與乙二醇等3項空氣污染物以不銹鋼吸附管採樣經由熱脫附儀搭配氣相層析質譜儀(TD/GC/MSD)分析，二乙醇胺(DEA)和醋酸(HAc)等2項目標化合物，則以衝擊瓶採樣再運用離子層析儀(IC)進行分析，5項化合物檢量線線性(R)皆可達0.995。若採樣體積為3 L時，空氣中N-甲基咯酮方法偵測極限(MDL)為3.59 µg/m3；異丁醇MDL可達0.70 µg/m3；至於感度略差之乙二醇MDL為72.32 µg/m3；二乙醇胺偵測極限若以採樣體積為60 L時，空氣中MDL可達2.48 µg/m3；至於吸收法採樣體積為60 L時，空氣中醋酸MDL可達2.51 µg/m3。保存期限測試中N-甲基咯酮等5目標化合物，於冷藏環境保存14天左右仍有90 %以上的回收率；依據實際採樣結果發現，除了IBA以外，NMP與EG於周界大氣濃度均低於配製濃度，推估安全採樣體積可高於6 L。以衝擊瓶採樣之目標化合物，DEA的捕集效率大約為73.2 ~ 111.5 %不等， HAc的捕集效率大約為102.4 ~ 107.6 %。各目標化合物精密度與準確度測試結果，其中N-甲基咯酮、乙二醇與異丁醇精密度分別為2.3%、4.8%與1.8%，準確度分析結果則分別為97.6~106.9 %、92.5~112.2 %與93.9~100.8 %；二乙醇胺精密度為0.75%，準確度分析結果則為98.7~101.7 %，醋酸精密度為0.58%，準確度分析結果則為109.9~112.5 %。另外，本計畫亦運用上述調查技術開發之採樣及分析條件，完成國內工廠7處次周界空氣之N-甲基咯酮等5種空氣污染物實廠調查，經由實廠驗證可知調查技術開發之可行。此外，計畫執行期間(101年7月、11月)分別視方法開發進度成果完成兩場次調查技術擴散課程，並提出3項周界空氣有機污染物方法調查技術草案，提供日後環保署檢測技術援引之參考。

摘要	The objective of this project was to develop sampling and analytical methods for N-methyl pyrrolidinone (NMP), isobutanol (IBA), ethylene glycol (EG), diethanolamine (DEA), and acetic acid (HAc) in ambient for Environmental Analysis Laboratory, EPA to establish standard operation methods. Based on previous study, all the compounds were planned to be sampled using stainless steel tubes or impinges, and then measured by TD-GC/MS or IC system. Due to the highly difference of physical properties, such as boiling points, ranging from 108 to 270 °C, saturated vapor pressures, ranging from 15.7 to 0.00014 mmHg, and viscosities, the sampling and analytical methods were categorized into two parts. NMP, IBA, EG were sampled using stainless steel tubes and measured by TD-GC/MS. DEA and HAc were sampled using impinges and measured by IC system. Based on our study results, the R values of calibration curves of all the five compounds were higher than 0.995. As for method detection limits (MDLs), NMP was 3.59 μg/m3, IBA was 0.70 μg/m3, and EG was 72.32 μg/m3 when sampling 3 liters, and DEA was 2.48 µg/m3 and HAc was 2.51μg/m3 when sampling 60 liters. As for preservation tests, the recoveries of all the five compounds were better than 90 % after storing at 4±1 °C for 14 days. Based on the field sampling results, except IBA, the concentrations of NMP and EG in ambient were lower than prepared concentrations, and therefore the safe sampling volume was estimated above 6 liters. For the compounds sampled by impinges, the capture efficiency of DEA was 73.2~111.5%, and the capture efficiency of HAc was 102.4~107.6 %. The precisions of NMP, IBA, EG, DEA, and HAc were 2.3 %, 1.8 %, 4.8 %, 0.75 %, and 0.58 %, respectively. The accuracies of NMP, IBA, EG, DEA, and HAc were 97.6~106.9 %, 93.9~100.8 %, 92.5~112.2 %, 98.7~101.7 %, and 109.9~112.5 %, respectively. The sampling and analytical methods developed in this project were proven to be practical by surveying the ambient air samples around 7 factories. Besides, two technical communication seminars were taken place on July and November. All the study results were reported in the technical draft for EPA’s reference.
