本報告研究目的為 (1)維護與改進跨國大氣長程傳輸送模式整合系統，掌握、預警及評估台灣環境受境外輸送之衝擊，提供環保署及地方環保單位進行空氣品質管理決策之參考；(2)針對空氣品質異常事件，修正事故發生時之空氣品質統計數值；(3)維護台灣酸雨監測網，進行長期監測與資料分析；(4)持續進行大氣汞溼沉降及重金屬監測網，評估對台灣的影響，估算長程輸送對台灣貢獻量；(5)更新與維護台灣酸雨資訊網；(6)積極推動及參與區域大氣污染相關議題之國際合作與技術交流。研究成果如下： 一、全國酸雨樣本合格率約85 %，達到聯合國世界氣象組織標準，顯示本計畫採樣流程及實驗分析維持相當良好之管制品質。 二、持續進行有害物質大氣汞及重金屬溼沉降監測網，並估算其長程輸送之貢獻，提供環保署及地方環保單位進行空氣品質管理決策之參考。 三、都會型測站之酸雨現象近年來具有輕微改善之現象，非都會型測站之酸雨卻有逐漸惡化之現象。 四、根據統計模式，已針對2010年沙塵事件進行空氣品質數值修正。 五、更新台灣酸雨網頁(http://www.acidrain.org.tw)，新增即時或近期之全球酸雨及環保相關議題之新聞等更多資訊。 六、持續推動參與國際合作與技術交流，積極推動加入聯合國品保品管計畫。

The goals of this study are (1) to establish and maintain an integrated atmospheric modeling system for studying the long-range transport of regional air pollutants in order to predict and assess their impact on Taiwan air quality, and further to provide fundamental information to EPA for air pollution management, (2) to revise the PSI when abnormal air pollution events occur, (3) to maintain acid deposition net work for conducting a long-term monitoring and data analysis, (4) to maintain an integrated atmospheric mercury and heavy metals for studying the long-range transport of regional air pollutants, (5) to update and maintain the web site of acid rain study in Taiwan, and (6) to promote regional international collaborations. To date, our achievements are highlighted below: The passing rate of the acid rain samples by the WMO QA/QC standard is 85%, showing the quality of the monitoring network is quite well. Maintain an integrated atmospheric mercury and heavy metals for studying the long-range transport of regional air pollutants in order to monitor and assess their impact on Taiwan air quality, and further to provide fundamental information to EPA for air pollution management.  The situation of acid rain in urban cities are slightly improving, but getting much more serious in the countryside. Based on a statistic model, the PSI during the abnormal event of the year of 2010 has been recalculated in consideration of Asian dust impact on PM10 measurements. The web site (http://acidrain.epa.gov.tw) of Taiwan acid rain study has been updated with more information Continue to promote participation in international cooperation and technical exchanges, and actively promote participation Quality Assurance Science Activity Center of UN.
