中文摘要	環保署自民國七十年開始設立空氣品質監測站網，期間共經歷過三次變革，至109年依據行政院核定之「102-109新世代環境品質監測及檢測計畫」，已完成空氣品質監測站檢討、調整與設備更新等工作。國內與AQI相關之關鍵污染物為PM2.5與臭氧，因此，降低這兩項關鍵污染物之監測誤差為環保署重要之技術發展工作之一。設置於高雄市鳳山區，附屬於空氣品質監測站網之品保實驗室的校驗技術量能，便扮演了確保使用儀具之量測準確度的功能，包含流量計與臭氧自動分析儀。環保署監資處在上述新世代計畫中啟動粒狀物自動監測儀器汰換更新工作，並利用新設置比對平臺，將手自動儀器等似性比對的方法納入實測驗收的程序中。新機台正式上線運作後，同步運用比對平臺進行自動監測查核機台維護與精密度測試，進以研擬採用自動監測儀器執行查核作業之可行機制，並建立查核機台品保條件。本計畫運用上述資源，執行工作目標包含：（一）推動PM10及PM2.5自動監測儀器性能評估作業；（二）實地場域比對平臺維運與全國監測網PM10及PM2.5自動監測儀器平行比對查核運作，確保儀器性能；（三）維持儀器流量品保校驗標準系統及追溯準確。計畫期間完成近兩年PM2.5自動儀器與標準方法（手動）量測數據比對，結果顯示110年度執行之強化維護措施：(1) HEPA零點測試調整，與(2) heater off功率調整，有效降低自手動差異。以週與月為週期評估PM2.5及PM10自動監測儀器性能，可追蹤到監測值有顯著偏移的機臺，並請維護廠商即時處理，同時依據觀察趨勢提出優先執行查核站點名單。PM2.5部分，已於111年10月8日累計完成66站次查核（計畫期間應完成60站次），夏季期間因環境濃度低，非必要不進行查核作業。PM10部分，於111年10月26日累計完成45站次查核（計畫期間應完成45站次）。空氣品質監測網品保實驗室校驗系統維護的部分，年度工作重點為臭氧自動分析儀校正系統申請ISO/IEC 17025認證，以確保校正結果的國際等同性；已於111年10月7日由全國認證基金會指定之評審員完成評鑑工作。

中文摘要

環保署自民國七十年開始設立空氣品質監測站網，期間共經歷過三次變革，至109年依據行政院核定之「102-109新世代環境品質監測及檢測計畫」，已完成空氣品質監測站檢討、調整與設備更新等工作。國內與AQI相關之關鍵污染物為PM2.5與臭氧，因此，降低這兩項關鍵污染物之監測誤差為環保署重要之技術發展工作之一。設置於高雄市鳳山區，附屬於空氣品質監測站網之品保實驗室的校驗技術量能，便扮演了確保使用儀具之量測準確度的功能，包含流量計與臭氧自動分析儀。環保署監資處在上述新世代計畫中啟動粒狀物自動監測儀器汰換更新工作，並利用新設置比對平臺，將手自動儀器等似性比對的方法納入實測驗收的程序中。新機台正式上線運作後，同步運用比對平臺進行自動監測查核機台維護與精密度測試，進以研擬採用自動監測儀器執行查核作業之可行機制，並建立查核機台品保條件。本計畫運用上述資源，執行工作目標包含：（一）推動PM10及PM2.5自動監測儀器性能評估作業；（二）實地場域比對平臺維運與全國監測網PM10及PM2.5自動監測儀器平行比對查核運作，確保儀器性能；（三）維持儀器流量品保校驗標準系統及追溯準確。計畫期間完成近兩年PM2.5自動儀器與標準方法（手動）量測數據比對，結果顯示110年度執行之強化維護措施：(1) HEPA零點測試調整，與(2) heater off功率調整，有效降低自手動差異。以週與月為週期評估PM2.5及PM10自動監測儀器性能，可追蹤到監測值有顯著偏移的機臺，並請維護廠商即時處理，同時依據觀察趨勢提出優先執行查核站點名單。PM2.5部分，已於111年10月8日累計完成66站次查核（計畫期間應完成60站次），夏季期間因環境濃度低，非必要不進行查核作業。PM10部分，於111年10月26日累計完成45站次查核（計畫期間應完成45站次）。空氣品質監測網品保實驗室校驗系統維護的部分，年度工作重點為臭氧自動分析儀校正系統申請ISO/IEC 17025認證，以確保校正結果的國際等同性；已於111年10月7日由全國認證基金會指定之評審員完成評鑑工作。

摘要	The Environmental Protection Agency (EPA) started to establish a network of air quality monitoring stations in 1981, and it has undergone three major changes since then. According to the "102-109 New Generation Environmental Quality Monitoring and Testing Program" approved by the Executive Yuan, several works had been completed by 2020, such as checks and adjustments of air quality monitoring stations and update of equipment. The key pollutants related to AQI in Taiwan are PM2.5 and ozone. Therefore, reducing the monitoring errors of PM2.5 and ozone is one of the important technical development tasks of the EPA. Set up in Fengshan District, Kaohsiung City, the Quality Assurance Laboratory, which belongs to the air quality monitoring station network, maintains relevant calibration techniques and measurement capacity. Therefore, it provides important functions to ensure the measurement accuracy of the instruments used, including flowmeters for PM sampling and ozone analyzers for ambient monitoring. In the above-mentioned New-Generation program, the Department of Environ-mental Monitoring and Information Management in EPA started the replacement and update of automatic particulate monitoring equipment and utilized the newly set up comparison platform to incorporate equivalence comparison of manual and automatic equipment into the acceptance process of actual monitoring data. After the new instruments are officially put into operation, the comparison platform will be used simultaneously to conduct maintenance and precision testing of the automatic monitoring and inspection machines. A feasible mechanism is being developed for using automatic monitoring equipment to perform inspection operations under adequate quality assurance conditions. Using the resources mentioned above, the objectives of this project include: (1) Promote the performance evaluation of PM10 and PM2.5 automatic monitoring instruments; (2) Maintain the field comparison platform and parallel comparison check of PM10 and PM2.5 automatic monitoring instruments for the national monitoring network to ensure the performance of the instruments; (3) Maintain the calibration standard system and traceability of instrument flow for quality assurance. Within the duration of the project, the comparison of data acquired by the PM2.5 automatic instrument and the standard method (manual) was conducted for the past two years. The results showed that the differences between the two could be effectively reduced by taking the enhanced maintenance measures implemented in 2011: (1) HEPA zero-point testing ＆ adjustment, and (2) heater off power adjustment. The performance of PM2.5 and PM10 automatic monitors was evaluated on a weekly and monthly basis. The monitors with significant deviations in monitoring values could be traced, and the maintenance personnel was requested to deal with them immediately. At the same time, a list of priority sites for QC checking was proposed based on the observed trend. For PM2.5, a total of 66 out of 60 station inspections committed in this project had been completed by Ocyober 2022. In summertime, the inspection work of QC checking was suspended due to the low environmental concentration. For PM10, a total of 45 out of 45 station inspections committed in this project had been completed by October 26, 2022. For the maintenance of the calibration system in Quality Assurance Laboratory of the air quality monitoring network, the focus of this year is to apply for ISO/IEC 17025 accreditation for the calibration system of the ozone automatic analyzer to ensure the international equivalence and metrological traceability of the calibration results. The assessment was already completed by the assessors appointed by Taiwan Accreditation Foundation on October 7, 2022.

摘要

The Environmental Protection Agency (EPA) started to establish a network of air quality monitoring stations in 1981, and it has undergone three major changes since then. According to the "102-109 New Generation Environmental Quality Monitoring and Testing Program" approved by the Executive Yuan, several works had been completed by 2020, such as checks and adjustments of air quality monitoring stations and update of equipment. The key pollutants related to AQI in Taiwan are PM2.5 and ozone. Therefore, reducing the monitoring errors of PM2.5 and ozone is one of the important technical development tasks of the EPA. Set up in Fengshan District, Kaohsiung City, the Quality Assurance Laboratory, which belongs to the air quality monitoring station network, maintains relevant calibration techniques and measurement capacity. Therefore, it provides important functions to ensure the measurement accuracy of the instruments used, including flowmeters for PM sampling and ozone analyzers for ambient monitoring. In the above-mentioned New-Generation program, the Department of Environ-mental Monitoring and Information Management in EPA started the replacement and update of automatic particulate monitoring equipment and utilized the newly set up comparison platform to incorporate equivalence comparison of manual and automatic equipment into the acceptance process of actual monitoring data. After the new instruments are officially put into operation, the comparison platform will be used simultaneously to conduct maintenance and precision testing of the automatic monitoring and inspection machines. A feasible mechanism is being developed for using automatic monitoring equipment to perform inspection operations under adequate quality assurance conditions. Using the resources mentioned above, the objectives of this project include: (1) Promote the performance evaluation of PM10 and PM2.5 automatic monitoring instruments; (2) Maintain the field comparison platform and parallel comparison check of PM10 and PM2.5 automatic monitoring instruments for the national monitoring network to ensure the performance of the instruments; (3) Maintain the calibration standard system and traceability of instrument flow for quality assurance. Within the duration of the project, the comparison of data acquired by the PM2.5 automatic instrument and the standard method (manual) was conducted for the past two years.
