104年度「臺中市環境品質監測站操作維護工作計畫」

中文摘要 本計畫執行期間為104年1月20日至104年12月31日，執行至今皆能完成環保局交付之各項任務與職責，主要工作內容包括空氣品質人工測站之採樣分析與保養維護、自動測站之定期維護、電子看板維護、固定式噪音監測站校正維護、移動式噪音測站監測、噪音管制系統維護與噪音相關報表提交、空品監測資料電子交換作業評估與建議、教育訓練、交通空品測站先期規劃與位置評估報告及審議等。 空氣品質人工測站方面，每月針對臺中市11座人工測站進行1次落塵採樣與分析、2次TSP採樣與分析及維護保養、1次流量單點校正與每季執行1次流量多點校正，目前各測站儀器設備狀況尚能正常運轉。104年1～11月平均測值與103年同期比較，各測站TSP平均值均低於103年。各站104年迄今歷次TSP濃度介於12～146μg/m3，均符合環保署空氣品質標準(250μg/m3)。季節變化以冬季TSP測值較高、夏季較低，TSP分析之成份中以硝酸鹽及硫酸鹽之比例較高。104年1～11月臺中市落塵平均為3.94公噸/平方公里/月，分級屬於極輕微污染，略低於去年同期之4.30公噸/平方公里/月。 在空氣品質自動測站部份，經由定期之每週、月、季、半年與年度維護保養，各測站各監測儀器皆能正常運作，各月份之資料可用率均在90%以上。硬體修繕部份，固定噪音測站中心端伺服器之防火牆故障，已更新實體防火牆。另配合環保局需要，將測站汰換下之冷氣機安裝至指定廳舍，充分物盡其用。烏日空氣品質自動測站配合設置場所管理單位(五光國小)，將氣象鐵塔搬遷至指定位置。而在人工測站部份，本公司則主動訂製11套高量採樣器帆布套(含框架)，以保護高量採樣器免受日曬雨淋而裂化。在交通空氣品質測站規劃部分，已於5月15日邀集專家學者及環保團體針對所提之交通測站規劃及位置評估報告進行審議，並決議優先設置交通空氣品質測站之路段。 在空品自動測站數據方面，SO2整體以臺電之清水、梧棲、大肚測站濃度較高，經由歷年各種管制措施之執行，各測站SO2濃度長期則有逐年下降趨勢。NO2濃度明顯以夏季較低、秋冬較高，整體濃度以烏日站、忠明站、大里站、霧峰站較高，主要受鄰近測站之移動污染源影響，長期大致呈現持平趨勢，豐原測站由衛生局搬遷至豐原高中後，NO2濃度有下降情形。O3濃度呈現春、秋較高之典型季節變化，大部分測站臭氧濃度長期大致呈持平趨勢。PM10濃度呈現冬、春較高之典型季節變化，長期呈現微幅下降趨勢。PM2.5之季節變化與PM10相似，長期亦呈現微幅下降趨勢。 依據環保署豐原、沙鹿、大里、忠明、西屯測站之監測資料，104年至12月底止臺中市之空氣品質不良率（PSI＞100）為0.93%。今年至12月底止中部空品區各縣市不良率，以臺中市(0.93%)最高，南投縣（0.55％）次之，彰化縣（0.27%）最低。而統計臺中市所有空氣品質監測站（含環保署、環保局、臺電測站）之監測資料，山、海、屯三區則以屯區之空氣品質不良率（0.92%）最高，山區（0.6%）次之，海區（0.29%）最低。 在噪音監測方面，固定式噪音監測站之校正維護作業及移動式噪音測站監測皆依預定進度執行，固定噪音站之資料可用率均達90%以上。固定式噪音測站以第二類噪音管制區之環境音量測站之不合格率較高，移動式噪音測站目前尚無不合格情形。在軟體操作維護與資料更新部份，除每月提送管制考評表、每季提交季報表、更新「噪音管制系統」之監測資料庫之外，並協助更新環保局網頁相關資料。

2015 Taichung City Environmental Quality Monitoring Station Operation And Maintance Project

英文摘要 This project was implemented from Jan. 20, 2015 to Dec. 31, 2015. 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, calibration and maintenance of Fixed Noise Monitoring Stations, Noise Monitoring of Mobile Noise Stations, regular maintenance of Electronic Billboard, submit all kinds of reports, training,and Evaluation the location of air quality Stations and deliberation, et cetera. In the section of Manual Operation Air Monitoring Stations, 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 2014, the mean concentration of TSP in year 2015 was lower than year 2014. The TSP geometric means of all Stations all meet the air quality standard in 2015. The concentration of TSP in winter was higher than in summer. There was a declining trend for long term of TSP, nitrate and sulfate have higher proportions of TSP's ingredients. The dustfall in Taichung City in 2015 was equally 3.94 ton/square kilometer/month, the graduation was extremely slightly pollute. 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 90%. In the project, we invited experts to perform functions verification and QA check, and we had improved instruments based on critical comments. In 2015, the ratio with PSI (Pollutant Standards Index) over 100 of Taichung City revealing in Taiwan EPA report was 0.93%. The monitoring data for the mid-Taiwan, the worst one was Taichung City standing for 0.93%, followed by Nantou County (0.55%), and then Changhua County (0.27%). Among Shan, Hai, and Tun, three districts of Taichung City, Tun district had the worst air quality from its highest ratio with PSI over 100（0.92％）and Hai had the best air quality. In the section of Noise Monitoring, the regular calibration and maintenance of Fixed Noise Monitoring Stations were completed according to the contract. The calibration report and monitoring data were submitted monthly and the data validity was above 90%. In the section of the Noise Monitoring of Mobile Noise Stations, that took twice quarterly monitoring tests at each spot, and according to predetermined progress execution. In the section of the Software Operation/Maintenance and Data Update, apart from submitting the self- evaluation forms and updating the database of the Noise Control Information System monthly, it provided EPB with the assistance of calculating and uploading the self-evaluation results to EPA’s Noise Control Information System quarterly.
