本報告研究目的為 (1) 維護台灣酸雨監測網，進行長期監測與資料分析；(2) 持續進行大氣汞溼沉降及重金屬監測網，估算其沉降量，並與國際現況比較；(3) 應用區域大氣模式整合系統，掌握、預警及評估台灣環境受局部或區域大氣污染物輸送之衝擊，提供環保署進行空氣品質管理與進行國際跨境污染傳輸責任歸屬評估決策之參考；(4) 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； (5)酸雨對台灣生態環境系統影響評估；(6)更新與維護台灣酸雨資訊網；(7) 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：  全國15站共收集到1162個樣本。pH值分布上，全國各測站所有樣本的平均pH值為5.55，高於酸雨pH值之標準(pH < 5)。  今年全國雨水酸化情況已見改善，全國各測站pH年平均值皆超過5.0，唯南北兩地雨水酸化的程度差異仍然存在。  模擬酸雨實驗結果顯示，虎皮蛙表皮的自由基生成量，可反應受酸雨影響的程度，並發現和附生腎蕨的反應相同，在pH 3.5-4.5之間為不利反應發生的臨界值，這可做為未來評估酸雨對動植物影響的重要參考指標。  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。  持續推動參與國際合作與技術交流，持續進行聯合國品保品管計畫合作、參與美國NADP/MDN全球資料品保品管比對計畫與聯合國全球降水化學及沉降科學評估資料庫。

The goals of this study are (1) to maintain acid deposition net work for conducting a long-term monitoring and data analysis, (2) to maintain the integrated atmospheric mercury and heavy metals monitoring network, estimate the mercury deposition and compare with the other countries’ monitoring data, (3) to establish and maintain an integrated atmospheric modeling system for studying the long-range transported air pollutants or local air pollutants in order to assess their impact to Taiwan air quality, and further to provide fundamental information to EPA for air pollution management, (4) to revise the PSI data when abnormal air pollution events occur, (5) to update and maintain the web site of acid rain study in Taiwan, and (6) to promote international collaborations and technical exchanges on regional air pollutant issues. To date, our achievements are highlighted below:  The 1662 samples in 15 stations all over Taiwan were obtained in 2013. The average pH for all the samples is 5.55.  The situation of acid rain in Taiwan is slightly improved. Annual average pH values for all sites are greater than 5.0. The north Taiwan is still worse than the southern Taiwan.  The acid rain simulationexperiment revealsthat the suddenlyraised level of free radicalsof Indian Bullfrog’s skin can reflect its response to acid rain.It also shows that there seems a critical value between pH 3.5-4.5, as the same as the result of Tuberous Sword Fernexperiment. Itcan be used as an important environmentalindicator of future assessmentof acid rain effects on plants and animals.  The web site (http://acidrain.epa.gov.tw) of Taiwan acid rain study has been updated with more information  We have continued to promote and participate international collaborations and technical exchanges, for example, Quality Assurance Science Activity Center of UN, the National Atmospheric Deposition Program/Mercury Deposition Network QA/QC program, and the World Meteorological Organization Global Precipitation Chemistry and Deposition Science Assessment.
