中文摘要	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監測網，進行監測數據分析；(3) 透過降雨時之天氣型態分類統計與區域大氣模式模擬方法，評估境內外污染對酸沉降之貢獻比例；(4) 藉由比對環保署與氣象局酸雨測站資料，評估整合雙方資源之可能性；(5) 協助環保署整併酸雨監測網資料並編撰酸雨年報，公開監測結果供民眾參考及藉此強化環境教育與新知傳播；(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。本年度研究重點成果如下： 1. 2021年與2022年1-8月採樣期間，全國各站pH值平均值均在5.0以上，全國pH值平均分別為5.92與5.80，高於酸雨pH值之標準(pH < 5)，顯示雨水酸化情況已見改善，唯南北兩地雨水酸化的程度差異仍然存在 2. 2021年至2022年8月期間，各測站之雨水樣品總汞濃度介於1.5與141.1 ng L-1；各測站之雨水汞權重平均濃度介於5.7 ng L-1與16.8 ng L-1，中、南部測站雨水汞權重平均濃度多高於北部測站。目前我國雨水汞濃度並未高於與其他國家。 3.整併酸雨網頁內容至環保署空氣品質改善維護資訊網(https://air.epa.gov.tw/)，並編撰2021年酸雨年報。 4.持續參與聯合國全球降水化學及沉降科學評估資料庫以及聯合國全球降水化學監測網品保中心全球比對。

摘要	The goals of this study are (1) to maintain acid deposition network for conducting a long-term monitoring and data analysis, (2) to maintain the integrated atmospheric mercury monitoring network and analyze the data, (3) to evaluate the contribution of local and long-range transport air pollutants to acid deposition through classification statistics of weather patterns during rainfall and simulation results from an integrated atmospheric modeling system, (4) to evaluate the possibility of integrating the resources of both EPA and CWB by comparing the acid rain of both parties, (5) to assist EPA in integrating the acid rain website and compiling the acid rain annual report, (7) to promote international cooperation and technical exchanges on regional air pollutant transport issues. To date, our achievements are highlighted below: 1. The annual average pH for all the samples in 2021 and 2022 (Jan-Aug) were 5.92 and 5.80 separately. The acid rain situation in Taiwan has slightly improved. The annual average pH values for most of the sites are greater than 5.0. Annual average pH values at Northern Taiwan sites are still lower than in southern Taiwan. 2. From 2021 January to 2022 August, the total mercury concentration from each station was between 1.5– 141.1 ng L-1. The weighted mean mercury concentration was between 5.7 – 16.8 ng L-1. This range of mercury concentration in Taiwan is now lower than the most majority of countries worldwide. 3. We have integrated the content of acid rain website into Air Quality Protection Web (https://air.epa.gov.tw/) and compiled the 2021 acid rain annual report. 4. Continued to promote and participated in international collaborations and technical exchanges, for example with the Quality Assurance Science Activity Center of the UN, and the WMO Global Precipitation Chemistry and Deposition Science Assessment.
