排放管道及周界中環亞乙基硫脲等 有害空氣污染物調查技術開發

中文摘要 本計畫目標為開發排放管道及周界中環亞乙基硫脲、鄰-苯二酚、對-苯二酚及4,4’-二胺基二苯甲烷等有害空氣污染物之調查技術評估。採樣方式以衝擊瓶採樣並搭配高效液相層析/串聯式質譜儀進行方法開發。 根據實驗結果，排放管道方面環亞乙基硫脲、鄰-苯二酚、對-苯二酚及4,4’-二胺基二苯甲烷之方法偵測極限，分別為0.043 ppbv、0.060 ppbv、0.138 ppbv及0.002 ppbv；準確度分別為99.2%、99.4%、103%及105%；精密度分別為5.86%、6.38%、3.86%及3.64%。 周界方面，環亞乙基硫脲、鄰-苯二酚、對-苯二酚及4,4’-二胺基二苯甲烷之方法偵測極限，分別為0.072 ppbv、0.118 ppbv、0.161 ppbv及0.007 ppbv；準確度分別為98.4%、99.4%、102%及101%；精密度分別為7.84%、7.88%、5.68%及5.09%。 本計畫亦運用上述調查技術開發之採樣及分析內容，完成國內排放管道或周界4場次現場調查，以及2場次技術擴散，分別在7月及11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 Ethylene Thiourea and other 3 Compounds in Stacks and Ambient Air

英文摘要 The objective of this project was to develop sampling and analytical methods for hazardous air pollutants, including ethylene thiourea (ETU), catechol, hydroquinone, and 4,4'-methylenedianiline (4,4'-MDA) in stacks and ambient air. All the compounds were sampled using impingers and then analyzed by LC/MS-MS. Based on experimental results, as for stacks, the detection limits of ETU, catechol, hydroquinone, and 4,4'-MDA were 0.043 ppbv, 0.060 ppbv, 0.138 ppbv, and 0.002 ppbv, respectively. Accuracy were 99.2%, 99.4%, 103% and 105%, respectively. Precision were 5.86%, 6.38%, 3.86%, and 3.64%, respectively. As for ambient air, the detection limits of ETU, catechol, hydroquinone, and 4,4'-MDA were 0.072 ppbv、0.118 ppbv、0.161 ppbv, respectively. Accuracy were 98.4%, 99.4%, 102%, and 101%, respectively. Precision were 7.84%, 7.88%, 5.68%, and 5.09%, respectively. The sampling and analytical methods developed in this project were proven to be practical by surveying at least 4 field samplings (air emission stacks or ambient air). Besides, two technical communication seminars were taken place in July and November. All the study results were reported in the technical drafts for EPA’s reference.
