三溴甲烷等有害空氣污染物調查技術開發

中文摘要 本計畫目標完成排放管道中三溴甲烷、1,1,2-三氯乙烷、1,4-二氯苯、苯甲氯、 1,2-二溴乙烷、1,4-二氧陸圜及1,1,2,2-四氯乙烷等7 種空氣污染物，以及周界中三 溴甲烷空氣污染物的調查技術評估。包含優化環檢所107 年度「排放管道中1,4-二 氧陸圜等十二種化合物調查技術開發」計畫之排放管道中1,1,2-三氯乙烷、1,4-二 氯苯、苯甲氯、1,2-二溴乙烷及1,4-二氧陸圜之採樣分析條件或技術，以及優化環 檢所NIEA A721 檢測方法之排放管道中1,1,2,2-四氯乙烷之採樣分析條件或技術。 根據實驗結果，排放管道中6 種目標待測物以保存性較佳的Tedlar 採樣袋測 試，其24 小時保存效果並不理想，評估結果顯示採樣袋並不適用本計畫之物種。 本團隊改以定流速採樣並搭配正己烷吸收液衝擊瓶，可得到良好之捕集效能，其物 種於吸收液之保存期限及方法偵測極限皆可滿足排放管道法規推估值標準。排放 管道中1,4-二氧陸圜水溶性高，以等速吸引採樣並搭配甲醇吸收液衝擊瓶，在三支 衝擊瓶串連下可得到良好之捕集效能，其方法偵測極限為0.035 ppmv，可滿足排 放管道法規推估值標準需求。周界中三溴甲烷則以不銹鋼桶採樣，樣品保存期限可 達14 天，方法偵測極限為0.039 ppbv。本計畫亦運用上述調查技術開發之採樣及 分析內容，完成國內排放管道及周界4 場次以上現場調查，及2 場次技術擴散，分 別在9 月及10 月舉行，並提出調查排放管道及周界中調查技術草案。

Development of Sampling and Analytical Methods for Bromoform and other 6 Compounds in Flue pipe and Ambient Air

英文摘要 The objective of this project was to develop the sampling and analytical methods for hazardous air pollutants, including bromoform, 1,1,2-trichloroethane, 1,4- dichlorobenzene, benzyl chloride, 1,2-dibromoethane, 1,4-dioxane, and 1,1,2,2- tetrachloroethane in flue pipe, and bromoform in ambient air. The sampling and analytical methods of 1,1,2-trichloroethane, 1,4-dichlorobenzene, benzyl chloride, 1,2- dibromoethane, and 1,4-dioxane, which were studied in EPA’s project in 2018, and the Method NIEA A721, which was published for 1,1,2,2-tetrachloroethane in flue pipe by Environmental Analysis Laboratory, were optimized in this study Based on the experiments, the storage results in 24 hours of six target compounds (bromoform, 1,1,2-trichloroethane, 1,4-dichlorobenzene, benzyl chloride, 1,2- dibromoethane, and 1,1,2,2-tetrachloroethane) in Tedlar sampling bags, which has better storage performance than others, were not acceptable, which indicated that the sampling method using Tedlar bags for this six compounds in flue pipe was not suitable. Afterwards, the sampling method using absorption solvent (hexane) with constant flow was evaluated. Based on the test results, the capture capacities, storages, and method detection limits were all qualified for the detection requirements of the emission standards of flue pipe. As for 1,4-dioxane, due to its solubility (miscible with water), the sampling method for flue pipe was absorption solvent (methanol) with isokinetic sampling. When three impingers were connected in series, the capture capacity was acceptable, the method detection limit was 0.035 ppmv, and the method was qualified for the detection requirement of the emission standard of flue pipe. As for bromoform in ambient air, the canister method was evaluated. The storage results in 14 days was acceptable, and the method detection limit was 0.039 ppbv. The sampling and analytical methods developed in this project were proven to be practical by surveying at least 4 field samplings (flue pipe 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.
