本計畫主要執行目標係藉著臺南市空氣品質監測站顯示系統設備維護工作，確保運轉正常及數據品質，同時彙整維修紀錄表及改善建議報告，提供環保局掌握維修狀況。並修訂測站維護之標準作業程序及維護檢查表格以確保維護品質，配合達成環保署監測站考核標準。 計畫執行成果簡述如下： 一、城西里測站部分 1.監測站操作維護 定期進行包括每週維護(48次)、每月維護(12次)、季維護(4次)、半年維護(2次)及年維護(1次)，所有作業皆依工作進度進行，計畫執行期間各設備之妥善率均達到100%。 季維護執行之分析儀多點校正，其相關係數皆在0.995以上，斜率皆在0.88~1.12之間，截距皆介於±2%F.S.，均符合測站績效查核標準。 2.數據管理 98年計畫期程各項分析儀及之氣象設備之資料獲取率皆在95%以上。 3.監測結果 城西里站有6站日不良(1站日O3；5站日PM10)，1站日達有害等級(PM10)；安南站有17站日不良(5站日O3；12站日PM10)，1站日非常不良(PM10)，2站日達有害等級(PM10)；臺南站有15站日不良(6站日O3；9站日PM10)，2站日非常不良(PM10)，1站日達有害等級(PM10)；在良好日比例中以城西站較其他兩站為高。 二、資訊看板部分 1.定期線路檢查及環境清潔 各月份檢查次數皆在4次以上。 2.顯示看板資料更新作業 計畫執行期程製作之相關文宣檔統計及撥放內容合計共達272筆，其中環保局共186筆，比例高達68%。 三、人工監測站部分 1.監測站操作維護 每月上、下半月定期進行監測站之操作及維護工作，並於次月10日前提交報表以供備查；計畫執行期間各設備之妥善率均達到100%。 2.校正作業 每月一次之單點檢查、每季一次之多點校正(98/05/05、98/08/06、98/11/25、99/02/06)及每半年一次之追溯一級校正作業(98/04/27、98/11/25)，各項校正結果均符合規範要求。 3.監測結果 本年度TSP監測結果中，除98年10月下旬各站測值外，其餘皆符合總懸浮微粒空氣品質標準24小時值(250μg/m3)；歷年(91年~98年)本市TSP監測結果顯示各年度之趨勢大抵一致，均呈現冬季高、夏季低之趨勢。 在落塵量監測部分，以極輕微污染佔44.4%為最多，其次為輕微污染29.2%，中度污染為22.2%及嚴重污染為4.2%。另外在歷年數據部分，落塵量年均值逐年下降，顯見管制之成效。 4.精密度測試 每季依序完成本市6座人工測站的精密度測試，計畫期程共完成12站次的併行採樣作業，整體誤差百分比介於-8.11%至8.14%之間，均符合誤差10%以內之要求。 5.空氣品質劣化季節懸浮微粒採樣 本項工作第1批次於98年11月02日至98年11月04日進行臺南站及安南站採樣作業(8樣品)，第2批次於98年12月03日進行臺南站採樣作業(2樣品)。 安南站PM10濃度以夜間略高於日間，TC及水溶性離子所佔比例亦以夜間較高於日間，元素比例則無差異；臺南站包含PM10濃度、TC、水溶性離子及元素比例均無明顯的日、夜間差異。 第一、二批次的劣化採樣，研判均可能是濁水溪揚塵所造成之懸浮微粒事件日。 四、宣導動畫、著色塗鴉、電子賀卡及小遊戲 辦理空氣污染防制宣導動畫競賽，藉由競賽活動推廣環保政策，並於得獎作品中提交宣導動畫4則、著色塗鴉1則、電子賀卡1則及小遊戲1則。

The achievements of this annual project are stated as below: For Chencily Auto-Monitoring Station, the data obtaining rates of the analyzers were all above 95%, whereas those of the meteorological equipments were above 96%. For the PM10 monitoring reports, Chencily, EPA Tainan and EPA Annan stations showed the significant season influences on PM10. The readings in summer were obviously lower than those in winter and the trends of the three Stations were identical. During the project period, from May 2009 to April 2010, PM10 counted for 26 episode days in total: 9 days at Tainan station, 12 days at Annan station and Chencily station had the least of 5 days. For the ozone (O3) monitoring reports, Chencily, EPA Tainan and EPA Annan stations had similar readings and the trends were also identical. During the project period, O3 counted for 12 episode days. Among them, Tainan station had the most of 6 days, Annan station stood at the second with 5 days, and Chencily station had the least of 1 days. The high value mostly happened in summer, which showed the impact of sunshine. NOX and NMHC are the two major factors that form ozone (O3). Since they are mainly from the discharge of motor vehicle and motorcycle, it explains why Tainan station, which locates in urban area, had the most episode days. The TSP results at the Manual Operation Monitoring Stations were complied with the air quality standard. From year 2002 to 2009, TSP values have been showing an identical trend, high in winter and low in summer. As for the analysis of TSP constituents, the concentration of Cl- was between 1.51~14.81μg/m3. The trends were identical, slightly higher in winter. The highest of 14.56μg/m3 occurred in 2004 and the lowest of 3.76μg/m3 did in 2002. The concentration of NO3- in TSP constituents was between 4.26~20.10μg/m3. The measurements over the past years showed a trend of high in winder and low in summer. The highest of 11.25μg/m3 occurred in 2003 and the lowest one of 8.96μg/m3 did in 2006. The concentration of SO42- in TSP constituents was between 7.82~32.25μg/m3. The highest of 17.26μg/m3 occurred in 2002 and the lowest of 11.23μg/m3 did in 2005. The concentration of Pb in TSP constituents was between 0.021~0.076μg/m3. The highest of 0.112μg/m3 occurred in 2002 and the lowest of 0.030μg/m3 did in 2005. The measurements of all stations were below the monthly mean (1.0 μg/m3) in accordance with the air quality standard. The trends of dust fall at the Manual Operation Monitoring Stations were all similar. In the past years, the highest value was 11.69 tons/square km/month in 2004 and the lowest value was 4.23 tons/square km/month in 2001. For the electronic billboard, a total of 272 advertisements were broadcasting. Among them, 186 were for Tainan EPB, which counts for 68%; the rest was for the Revenue Service Office, Tainan City Government, National Tax Administration, etc. It certainly has provided an effective way to publicize the environmental protection policies. the Manual Operation Monitoring Stations have already been used for many years, from 1992 to the present, the equipment has been already old. This plan proposes compiling funds and changing the old motorcycle. This method can reduce personnel working time and part replace.
