中文摘要	本計畫執行期限為自民國105年10月27日至107年10月26日止，計畫主要通過對PM2.5手動監測儀執行現場查核、實驗室秤重查核及現場平行比對等品保作業，監督三區採樣單位執行PM2.5採樣作業之確實性、採樣器運轉準確度及監測資料之可信度，以達到確保採樣及秤重分析品質，提升數據可信度目的。　　現場儀器查核主要針對採樣器運轉準確度狀況進行查核，本計畫共完成372站次，整體查核滿意率為99.1%。另現場人員操作程序查核共完成187站次，查核缺失2項次，後續皆已完成改善。　　實驗室秤重查核主要針對濾紙調理秤重、實驗室作業及品質管理等項目進行查核，確保秤重作業之品質。本計畫共完成8次三區實驗室濾紙重複秤重查核，各區查核缺失項皆已完成改善。另每半年與三區執行1次實驗室間秤重比對，本計畫共計完成4次實驗室間秤重比對，其中於第一次實驗室間秤重比對中，中區1筆及南區2筆數據超出允收規範，後續比對皆符合允收規範。　　儀器採樣比對主要依據環檢所公告方法，與測站手動採樣器同步採樣，以確保數據可信度。本計畫共完成4次共同比對，比對結果精密度介於1.65%~4.36%間，符合≦10%之規範。另現場平行比對共完成248站次，其中236筆監測濃度大於等於3 μg/m3，為有效比對濃度值，且比對濃度差值多數落於0~±1 μg/m3間，顯示PM2.5手動監測值具高度可信度。　　PM2.5手動監測數據品保審查主要確認三區採樣單位每3天執行一次採樣分析作業之程序、表單填寫、濃度計算、實驗室品保品管等，與環檢所公告方法之符合性。本計畫至107年10月26日止，針對31個測站7,562筆監測數據進行品保審查，其中「暫停採樣」5站次、「採樣失敗」188站次、「品保失敗」10站次、「有效數據」7,359筆，整體數據可用率為97.3%。　　無論現場查核、實驗室秤重查核等作業所發現之缺失項，皆於每次月維護會議中提出檢討，並由三區採樣單位提出改善狀況，後續由環保署及本計畫執行缺失改善追蹤。

摘要	This report provides information of quality assurance for PM2.5 sampling activities from October 27, 2016 through October 26, 2018. The mission of the project comprises implementation of inspection, performance audit, and collocated comparison for field sampling and lab analyzing, so that requirements and goals for PM2.5 monitoring will be fulfilled. 　　The performance audit used independent instruments and standards to inspect the deviation between the monitoring value and the standard value (accuracy). 372 stations were completed in two years. The acceptance rate was 99.1%. In addition, 187 stations, 2 items of procedure check for field operators were also included. And must follow up tracking the results of defects improvement. 　　A quality system check for laboratory refers to the organizational resources, processes and procedures to implement quality management. 24 Lab system audits and 4 inter-lab weighting comparisons have been accomplished in two years. Only three of the comparisons failed to meet the requirement. 　　The semi-annual collocation measurement is mainly based on the published method NIEA A205.11C by EPA Environmental analysis laboratory, to enhance the reliability of monitoring data. Four times of collocated measurement between standard instruments were conducted in two years, and precision showed between 1.65%~4.36% which were all meet the requirement. 248 field stations collocated comparisons were done in two years. 236 times valid comparisons were under circumstances of PM2.5 concentrations greater than 3 μg/m3. 0~±1 μg/m3 of concentration bias indicate a high credibility of PM2.5 manual monitoring data. 　　Data verification and validation were mainly focus on worksheet filling, concentration calculations and quality management of laboratory, to meet the requirement of NIEA method. 7,562 pieces of data validations were carried out in this project. Among these data, 188 were marked “sample failed”, 10 were marked “quality assurance failure”, and 5 were marked “not executed sample.” The overall rate of available data is 97.3%. 　　All defects from field performance audit and Lab check will be require to improve within certain days discussed in monthly routine data reviewing meeting, The EPA and this project will track situation of defects improvement.
