本計畫主要工作目標包括：1.執行光化學評估監測站儀器設備品保查核，確保測站儀器功能正常。2.執行光化學評估監測站監測數據品保作業。3.區域污染特徵及區域臭氧生成潛勢分析。 本年度執行成果在儀器品保部分，除完成品保查核作業手冊修定外，同時亦依核定之作業手冊規範完成各項查核，現場查核缺失部份已改善完成；數據品質查核方面，105年度9個監測站及2個監測車共18個站月的數據可用率未達90%的要求，106年共26個站月的數據可用率未達90%的要求，主要原因：1.標準品超過允收標準，2.儀器老舊部份機械性作動零件產生老化現象。 系統查核結果顯示，各測站於查核的化合物其滯留時間相對差異百分比均符合品保規範±5%，且差異範圍均於1分鐘以內；105年度績效查核結果，5號監測車有少數物種(包括Toluene、Styrene)偏差超出品保設定±25%，106年度績效查核項目均符合品保規範。 105年度光化監測結果與臭氧的相關性解析，顯示忠明站對臭氧貢獻量最大，臺西站貢獻量最小，106年度顯示忠明站對臭氧貢獻量最大，臺西站貢獻量最小。依據105及106年光化監測結果各測站大多有汽機車尾氣排放之特徵污染物，萬華站及土城站有異戊烷，忠明站及朴子站有間,對-二甲苯，臺西站有丙烯，橋頭站有1-丁烯，小港站有異戊烷、乙烯、正丁烷，潮州站有正丁烷。

The main objectives of this program included implementing the quality assurance audits of analytical systems for Photochemical Assessment Monitoring Stations (PAMS), standardizing the data processing procedures for the collected results, characterizing the local pollutant profiles of different regions, evaluating the current effectiveness of the Photochemical Assessment Monitoring Stations (PAMS) operation. The instrument quality assurance auditing manual was revised and audits error were carried out accordingly of the program achievement. In the other hands, the availability of 9 stations and 2 mobile laboratory, which have 18 times for 2016, and 26 times for 2017 had less than 90% of the quality assurance criteria because standard going beyond the acceptance criteria and aging of the instrument parts. The system quality assurance audits results indicated that the relative percent deviations of retention times of all stations met the quality assurance criteria of ± 5% and the deviation range within 1 minute. The annual performance check results indicated a few compounds, include Toluene and Styrene, were found to exceed the ± 25% limit for Mobile Laboratory 5 for 2016, and the annual performance check results indicated that all stations met the quality control criteria of ±25% for 2017. Photochemical monitoring results and ozone relative analysis in 2016 show that the most ozone contribution comes from Zhongming station while the least ozone contribution comes from Taixi station, And most ozone contribution comes from Zhongming station while the least ozone contribution comes from Taixi station for 2017. According to Photochemical monitoring results for 2016 and 2017, characteristic pollutant of mobile exhaust had found from most of the monitoring station in photochemical monitoring results, iso-Pentane(gas station) had found in Wanhua and Tucheng station, m,p-Xylene(wastewater treatment plant) in Zhongming station and Puzi station, Propylene(Petrochemical Industry) in Taixi station, 1-Butene (Petrochemical Industry) in Qiaotou station, iso-Pentane(gas station), Ethane, n-Butane(Petrochemical Industry) had found in Xiaogang station, n-Butane in Chaozhou station(Petrochemical Industry).
