監測儀器性能比對作業規劃及數據分析

中文摘要 本計畫主要工作為規劃懸浮微粒監測儀器之性能比對作業,並執行後續的比對數據統計分析,建立本土資料庫。目前包括我國在內之世界各國,多以手動採樣法作為量測大氣中懸浮微粒質量濃度的標準方法。由於懸浮微粒自動監測數據和手動檢測原理、條件不同,其結果會有差異,故有必要執行嚴謹之自動/手動檢測儀器平行比對,評估監測儀器之精密度,確認自動/手動檢測儀器數據之可比較性,以提升懸浮微粒監測數據之可信度。計畫主要工作項目包括:規劃PM10 & PM2.5監測儀器精密度及性能比對作業機制、執行比對品質監管與結果數據分析、規劃PM10 & PM2.5自動監測儀器汰換採購作業、以及建立臭氧與懸浮微粒監測計量之國際標準追溯機制。量測儀器提供之數據準確度必須建立在完成計量追溯的基礎上,而計量追溯則代表透過不間斷的校正鏈使量測結果可連結到參考基準。本計畫最後一項工作內容為協助規畫環保署維持之臭氧原級標準系統可連結至國際比對平台,執行懸浮微粒監測儀器標準濃度驗證系統建置的可行性規劃,以提升我國懸浮微粒及臭氧監測與國際等同之校準量能。

Collocation study plan for the comparison of monitoring instruments and its data analysis

英文摘要 The major objectives of this project are to make a plan for inter-comparisons of particulate matter (PM, including PM10 and PM2.5) monitoring instruments, to confirm the comparability of these PM monitors, and to establish a local PM monitoring database. The current reference methods for measuring the mass concentration of PM in ambient air are based on a 24-hour collection followed by gravimetric analysis. However, continuous automated monitors are required in the monitoring networks to provide real-time information. These automated monitors are based on different operation principles than the reference method. Therefore it is necessary to demonstrate that the automated instruments can produce results that are comparable with the reference method. This is mainly done by executing parallel comparative measurements between collocated reference and automated monitors. Through comprehensive statistical analysis, precision and regression parameters will be evaluated to examine the degree of equivalence for the PM monitors that are used in this study. The reliability of reported monitoring data can be enhanced upon the demonstration of equivalence and comparability. The tasks in this project can be divided into four parts: (1) Sketch a program for inter-comparisons of PM10 and PM2.5 monitoring instruments; (2) Conduct statistical analysis for the resulting comparison data to examine measurement comparability; (3) Make a draft of the Purchasing Policy & Procedure Guide for PM monitoring instruments; (4) Propose a mechanism to help EPA establish internationally recognized metrological traceability on ozone and particulate matter measurement. The accuracy of measuring data is based on the metrological traceability. The last task of this project is to propose the practical plans for EPA to build standard systems and establish the metrological traceability for ozone and particulate matter measurements.
