中文摘要	汞是全球性污染物，經由大氣長程傳輸到達全球各地，透過大氣乾、濕沈降回地表，進入水域生態系統，可被微生物轉化成高毒性的甲基汞，然後藉由食物鏈生物累積與生物放大作用，在水生生物體內累積至高濃度，再經由攝食危害人體健康。要緩解此「全球汞污染」問題，必須經由國際合作，釐清大氣汞排放、長程傳輸、物理與化學轉化、沈降、排放源與受體關係等機制，據以評估聯合國環境規劃署(UNEP)「水俣汞公約(Minamata Convention on Mercury)」實行成效，動態調整策略，以保護人體健康和環境免受汞及其化合物的危害。已知東亞、東南亞與南亞是全球最主要人為大氣汞排放源區，但印太地區國家及太平洋島嶼國家仍普遍缺乏量測大氣汞及汞濕沈降監測技術，成為大氣汞監測資料空白區。本研究計畫目標如下：一、協助本署辦理大氣汞相關國際合作活動。二、賡續運作環境監測技術聯合中心。三、賡續運作亞太地區大氣汞監測教育訓練平臺，提供環境監測技術諮詢及相關訓練，協助亞太汞監測網夥伴國家提升環境監測能量。主要工作為協助我國環境部與美國環保署(USEPA)及美國大氣沈降計畫(National Atmospheric Deposition Program, NADP)共同合作，在雙方環保技術合作架構上，以「環境監測技術聯合中心」做為區域技術中心，持續運作「亞太地區汞監測網(Asia Pacific Mercury Monitoring Network, APMMN)」，拓展區域大氣汞監測活動；協助分析亞太地區國家大氣汞樣品，並強化QA/QC作業；施行人員教育訓練，協助亞太地區國家建立汞超微量採樣與分析能力，提昇監測能量；促進大氣汞監測多邊合作，推動監測資料交換與分享；研析亞太地區大氣汞分布特徵、變化及影響。本期成果包含： (1) 與環境部、USEPA及NADP視訊會議討論APMMN活動及發展； (2) 台日濕沈降採樣器平行比對實驗延續至2024年5月； (3) 與USEPA合作進行被動式大氣汞採樣先期測試； (4) 執行濕沈降樣本總汞分析品保品管作業； (5) 「亞太地區汞監測網」網頁維護與更新； (6) 視訊參與2023 NADP春季MELD科學研討會； (7) 視訊參與2023 NADP秋季MELD科學研討會； (8) 參加第三十一屆太平洋島國環境大會； (9) 參與聯合國環境署亞洲及太平洋區域辦事處(UNEP ROAP)辦理的第二回合汞實驗室能力驗證試驗，結果為滿意(Satisfactory)； (10) 參與加拿大環境與氣候變遷部(ECCC)全球被動式大氣汞採樣計畫； (11) 完成289件APMMN濕沈降總汞分析，包含196個濕沈降樣本與93個品保樣本； (12) 完成汞濕沈降採樣器平行比對樣本分析222件； (13) 收集彙整亞太地區大氣汞監測資料； (14) 收集彙整國際雨水汞濃度資料； (15) 分析亞太地區大氣汞輸出對我國的影響； (16) 收集國際新進大氣汞監測技術； (17) 協助夥伴國家操作維護汞濕沈降採樣測站； (18) 協助夥伴國家分析被動式大氣汞裝置樣本38件； (19) 協助帛琉建置汞濕沈降採樣技術； (20) 辦理第十二屆亞太地區汞監測網年會。

摘要	Mercury (Hg) is a global pollutant, which is distributed worldwide due to atmospheric long-range transport. Via dry and wet atmospheric deposition, Hg enters aquatic ecosystems, where it could be transformed to highly toxic methylmercury (MeHg) by microorganisms. MeHg can be bioaccumulated and biomagnified through food chain to higher concentrations in some fish that could be hazardous to human health through consumption. To ease this global Hg pollution issue, international collaboration is required to clarify the mechanisoms of emissions, long-range transport, physical and chemical transformation, deposition, source-receptor relationships. The effectiveness of the Minamata Convention can be evaluated besed based on the collected information and data, and strategy can be adjusted accordingly, to protect human health and the environment from the hazards of Hg and its compounds. Although East, Southeast and South Asia are major emission source regions of Hg to the atmosphere, the ultra-trace level sampling and analytical techniques required for quantifying atmospheric Hg concentrations and fluxes are lacking in many countries, making Southeast and South Asia a blank area of atmospheric Hg monitoring.

摘要

Mercury (Hg) is a global pollutant, which is distributed worldwide due to atmospheric long-range transport. Via dry and wet atmospheric deposition, Hg enters aquatic ecosystems, where it could be transformed to highly toxic methylmercury (MeHg) by microorganisms. MeHg can be bioaccumulated and biomagnified through food chain to higher concentrations in some fish that could be hazardous to human health through consumption. To ease this global Hg pollution issue, international collaboration is required to clarify the mechanisoms of emissions, long-range transport, physical and chemical transformation, deposition, source-receptor relationships. The effectiveness of the Minamata Convention can be evaluated besed based on the collected information and data, and strategy can be adjusted accordingly, to protect human health and the environment from the hazards of Hg and its compounds. Although East, Southeast and South Asia are major emission source regions of Hg to the atmosphere, the ultra-trace level sampling and analytical techniques required for quantifying atmospheric Hg concentrations and fluxes are lacking in many countries, making Southeast and South Asia a blank area of atmospheric Hg monitoring. Therefore, this project is aimed to ameliorate this situation with following objectives: (1) assisting the Ministry of Environment of Taiwan to handle atmospheric Hg related international collaborative activities; (2) continuing operation of the Center for Environmental Monitoring and Technology; (3) continuing operation of the atmospheric Hg monitoring education and training platform of the Asia-Pacific region; providing consultation and training in environmental monitoring techniques; assisting APMMN partner countries in environmental monitoring capacity enhancement.
