中文摘要	計畫執行期間為九十一年三月十九日至十二月三十一日止，本工作團隊依約完成環保局交付之任務與職責。九十一年度三至十二月份，四個空氣品質自動測站資料可用率均達85 % 以上。本年度三處空氣品質人工測站儀器設備運轉正常，TSP採樣每上、下半月各一次，落塵每月採、放樣各一次。分析結果顯示，除鉛成分外，硝酸鹽、硫酸鹽、氯鹽、正己烷及落塵量監測值均呈現：豐原>梧棲>霧峰。各監測項年平均濃度－硝酸鹽濃度4.17μg/m3、硫酸鹽15.9μg/m3、氯鹽3.7μg/m3、鉛0.087μg/m3、正己烷28.4μg/m3、落塵量約為3.51±0.16公噸/平方公里/月。依環保署設置於台中縣三個空氣品質監測站(豐原站、沙鹿站與大里站)監測值分析，八十六年至九十一年空氣品質變化趨勢歸納：SO2監測濃度逐年下降，與近年空污法施行，要求工廠加裝污染防制設備及燃油低硫份之限制有關。SO2年平均監測濃度在3-8 ppb之間，皆未超過空氣品質年平均標準30 ppb。NO2監測濃度除大里測站維持在25~28 ppb之間，豐原站及沙鹿測站的年平均濃度均有下降之趨勢，NO2年平均監測濃度為20~27ppb，皆未超過空氣品質年平均標準50 ppb。O3濃度有逐年上升之趨勢，九十一年O3年平均濃度是近六年來最高，達24.4ppb，特別是豐原測站臭氧惡化情況嚴重，大里測站次之。PM10監測濃度有逐年下降之趨勢。由於環保署濃度平均值資料係扣除大陸沙塵暴影響之日期，故與實際之空氣品質會有所差異。CO監測濃度顯示近幾年的測值都非常接近，介於0.6 ppm至1.0 ppm之間，沙鹿站較其他兩站略低，各測站並無明顯之逐年上升或下降趨勢。九十一年台中縣環保局四個自動測站與環保署三個自動測站所屬之各空氣品質監測站PSI≥100發生日數統計發現，九十一年與九十年相比較；PSI≥100臭氧指標污染日數大幅增加，其中又以太平站及霧峰站惡化情形較為嚴重。懸浮微粒污染日數降低，且各站均有改善趨勢。

中文摘要

計畫執行期間為九十一年三月十九日至十二月三十一日止，本工作團隊依約完成環保局交付之任務與職責。九十一年度三至十二月份，四個空氣品質自動測站資料可用率均達85 % 以上。本年度三處空氣品質人工測站儀器設備運轉正常，TSP採樣每上、下半月各一次，落塵每月採、放樣各一次。分析結果顯示，除鉛成分外，硝酸鹽、硫酸鹽、氯鹽、正己烷及落塵量監測值均呈現：豐原>梧棲>霧峰。各監測項年平均濃度－硝酸鹽濃度4.17μg/m3、硫酸鹽15.9μg/m3、氯鹽3.7μg/m3、鉛0.087μg/m3、正己烷28.4μg/m3、落塵量約為3.51±0.16公噸/平方公里/月。依環保署設置於台中縣三個空氣品質監測站(豐原站、沙鹿站與大里站)監測值分析，八十六年至九十一年空氣品質變化趨勢歸納：SO2監測濃度逐年下降，與近年空污法施行，要求工廠加裝污染防制設備及燃油低硫份之限制有關。SO2年平均監測濃度在3-8 ppb之間，皆未超過空氣品質年平均標準30 ppb。NO2監測濃度除大里測站維持在25~28 ppb之間，豐原站及沙鹿測站的年平均濃度均有下降之趨勢，NO2年平均監測濃度為20~27ppb，皆未超過空氣品質年平均標準50 ppb。O3濃度有逐年上升之趨勢，九十一年O3年平均濃度是近六年來最高，達24.4ppb，特別是豐原測站臭氧惡化情況嚴重，大里測站次之。PM10監測濃度有逐年下降之趨勢。由於環保署濃度平均值資料係扣除大陸沙塵暴影響之日期，故與實際之空氣品質會有所差異。CO監測濃度顯示近幾年的測值都非常接近，介於0.6 ppm至1.0 ppm之間，沙鹿站較其他兩站略低，各測站並無明顯之逐年上升或下降趨勢。九十一年台中縣環保局四個自動測站與環保署三個自動測站所屬之各空氣品質監測站PSI≥100發生日數統計發現，九十一年與九十年相比較；PSI≥100臭氧指標污染日數大幅增加，其中又以太平站及霧峰站惡化情形較為嚴重。懸浮微粒污染日數降低，且各站均有改善趨勢。

摘要	This project was implemented from Mar. 19, 2002 to Dec. 31, 2002. All the tasks defined in the contract had been completed including the sampling analysis, maintenance of the Manual Operation Air Monitoring Stations, regular maintenance of Auto-Monitoring Stations. In the section of Manual Operation Air Monitoring Stations, this project had covered the following missions in Fengyuan, Wuchi and Wufeng. There are monthly sampling and analysis of dust fall, monthly one-point flow rate calibration, every half months TSP sampling analysis and maintenance, quarterly multiple-point flow rate calibration. All equipments in Manual Operation Air Monitoring Stations are in good working conditions. In contrast with year 2002, the mean concentration of TSP in year 2002 was obviously higher than that in year 2001. In the section of Auto-Monitoring Stations, all measurement items were functioning well under weekly, monthly, quarterly, semi-annual and annual maintenance scheme. The data validity all achieved above 85%. . In 2002, the PSI (Pollutant Standards Index) of Taichung County revealing in Taiwan EPA report was 2.1%. The measurement data for the mid-Taiwan, the worst one was Changhua County standing for 4.0%, followed by Taichung County (2.8%),Nantou County (2.6%), and then Taichung County (2.1%). As to the Maximum Index Pollutants, ozone and PM10 both contributed the half part.
