中文摘要	本計畫目標為開發乙醯胺、二甲基甲醯胺、二甲基乙醯胺及丙烯醯胺等有害空氣污染物之調查技術。針對排放管道，參考環檢所公告方法NIEA A737.71 B進行優化，乙醯胺、二甲基甲醯胺、二甲基乙醯胺及丙烯醯胺，以甲醇吸收液採樣 (等速吸引採樣)，GC/MS進行分析。針對周界，由於環檢所公告方法NIEA A742.10.7B受限於採氣流量小，無法優化以降低方法偵測極限。乙醯胺、二甲基甲醯胺及二甲基乙醯胺，以甲醇吸收液採樣，GC/MS進行分析；丙烯醯胺則同樣以甲醇吸收液採樣，LC/MS-MS進行分析，此方法採樣分析流程的玻璃器皿必須經過去活化處理，避免待測物吸附於玻璃表面。根據實驗結果，排放管道方面，乙醯胺、二甲基甲醯胺、二甲基乙醯胺及丙烯醯胺之方法偵測極限 (採氣量150L，5 L/min × 30 min)，分別為0.057 ppmv、0.049 ppmv、0.055 ppmv及0.034 ppmv；準確度分別為105.14 %、108.14 %、92.14 %及91.14 %；精密度分別為6.86 %、6.68 %、6.09 %及6.09 %。周界方面，乙醯胺、二甲基甲醯胺、二甲基乙醯胺及丙烯醯胺之方法偵測極限 (採氣量180L，3 L/min × 60 min)，分別為14.18 ppbv、9.12 ppbv、26.40 ppbv及0.106 ppbv；準確度分別為112.14 %、110.14 %、104.00 %及101.81 %；精密度分別為6.36 %、9.29 %、9.60 %及4.27 %。此外，丙烯醯胺可藉由濃縮方式降低方法偵測下限。本計畫亦運用上述調查技術開發之採樣及分析條件，完成國內排放管道或周界至少4場次現場調查。此外，本計畫在9月及10月舉行2場次技術擴散課程，並提出調查技術草案。

摘要	The objective of this project was to develop sampling and analytical methods for hazardous air pollutants, including acetamide, dimethylformamide, dimethylacetamide, and acrylamide in stacks and ambient air. As for stacks, acetamide, dimethylformamide, dimethylacetamide, and acetamide were sampled using absorption solvent (methanol) (isokinetic sampling) and then analyzed by GC/MS, which followed the Method NIEA A737.71B published by Environmental Analysis Laboratory with optimization. As for ambient air, Method NIEA A742.10.7B, which was published by Environmental Analysis Laboratory, cannot be optimized for lowering the detection limit due to the limitation of small sampling flow rate. Therefore, acetamide, dimethylformamide, and dimethylacetamide were sampled using absorption solvent (methanol) and then analyzed by GC/MS. Acrylamide was sampled using absorption solvent (methanol) and then analyzed by LC/MS-MS, and all glassware must be silanized before experiments to prevent the analyte from adsorbing on the surface. Besides, the detection limit of acrylamide can be lowered by concentration. Based on experimental results, as for stacks, the detection limits of acetamide, dimethylformamide, dimethylacetamide, and acetamide were 0.057 ppmv, 0.049 ppmv, 0.055 ppmv, and 0.034 ppmv, respectively (sampling volume was 150L, 5 L/min × 30 min). Accuracy were 105.14 %, 108.14 %, 92.14 %, and 91.14 %, respectively. Precision were 6.86 %, 6.68 %, 6.09 %, and 6.09 %, respectively.As for ambient air, the detection limits of acetamide, dimethylformamide, dimethylacetamide, and acetamide were 14.18 ppbv, 9.12 ppbv, 26.40 ppbv, and 0.106 ppbv, respectively. Accuracy were 112.14 %, 110.14 %, 104.00 %, and 101.81 %, respectively. Precision were 6.36 %, 9.29 %, 9.60 %, and 4.27 %, respectively (sampling volume was 180L, 3 L/min × 60 min). The sampling and analytical methods developed in this project were proven to be practical by surveying at least 4 field samplings (stacks or ambient air). Besides, two technical communication seminars were taken place in September and October. All the study results were reported in the technical drafts for EPA’s reference.
