本計畫執行期間為105年1月12日至105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、移動式空氣品質監測車操作維護、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。105年平均測值與104年比較，各測站TSP平均值均低於104年。各站105年迄今歷次TSP濃度介於10～120μg/m3之間，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。105年臺中市落塵平均為1.89公噸/平方公里/月，分級屬於極輕微污染，低於去年同期之3.85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，各測站各月份之平均資料可用率皆達93%以上。硬體修繕部份，大甲測站之電錶損壞鬆脫，已委託水電工程公司修復。大甲測站鋼瓶室門遭強風吹落，已委託廠商焊接固定。北新國中人工測站之落塵桶架為舊式，體積大且重量重，校方因安全考量要求吊離並更換之，故以吊車將落塵桶架及水泥底座吊離，並重新製作落塵桶架及其水泥底座。精密機械園區電子看板部份顯示模組損壞，委託電子看板廠商更新損壞的顯示模組。春社公園電子看板之接收卡及電源供應器損壞導致看板無法顯示，委託電子看板廠商修復看板控制系統。 在空品自動測站數據日夜變化方面，CO與NO2受移動污染源影響，於上下班時段濃度會較高，尤其以大里及忠明測站較明顯，O3則是因光化作用，於中午時段濃度較高，以大里與太平測站中午時段濃度較高。在季節變化方面，大部分污染物濃度以夏季較低，冬、春較高，其原因與臺灣的天氣型態有關，夏季颱風多、熱對流旺盛，擴散條件佳，因此污染物不易累積。O3於3~4月(春季)及9~10月(秋季)期間測值較高，呈現O3典型之季節變化。 在空品自動測站測值長期趨勢方面，SO2整體以臺電之梧棲、龍井測站濃度較高，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整體濃度以忠明站、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，而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濃度大部分測站臭氧濃度長期大致呈持平趨勢。PM10各站濃度長期呈現些微下降趨勢，顯示歷年之各項粒狀物管制工作已見成效。PM2.5之變化趨勢與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，105年臺中市之空氣品質不良率（PSI＞100）為0.78%。今年至11月底止中部空品區各縣市不良率，以臺中市(0.78%)最高，南投縣與彰化縣較低（均為0.3%）。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，臺中市山、海、屯三區則以山區之空氣品質不良率（0.67%）最高，屯區（0.55%）次之，海區（0.35%）最低。 在移動式空氣品質監測車方面，定期執行移動式空品監測車監測設備維護工作，並依據民眾陳情及環保局指示進行空氣品質監測，截至12月止已完成18處次之監測。監測完畢之後，除提交監測數據外，亦針對監測數據進行解析，彙整監測地點附近可能污染源，提供其他計畫執行稽查之參考。監測車每月之資料可用率均達90%以上，符合契約要求。移動式空氣品質監測車除執行空氣品質監測之外，亦協助分析相關單位採集之樣品共43件。 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93%以上。而月湖活動中心固定式噪音測站於9月份遭梅姬颱風損壞，因無零件可修復，第四季起改以移動式噪音測站監測。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。

This project was implemented from Jan. 12, 2016 to Dec. 31, 2016. All tasks defined in the Environmental Protection Bureau's contract had been completed including the sampling analysis, maintenance of the manual operation air monitoring stations, regular maintenance of auto air 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, evaluation the location of air quality stations and deliberation, et cetera. In the section of Manual Operation Air Monitoring Stations, there were monthly sampling, analysis of dust fall, monthly one-point flow rate calibration, every half months TSP sampling analysis and maintenance, quarterly multiple-points flow rate calibration. All equipment in Manual Operation Air Monitoring Stations are in good conditions. In contrast with year 2015, the average concentration of TSP in year 2016 was lower than year 2015. The TSP concentration between 10～120μg/m3 was meant that all stations meet the Environmental Protection Administration air quality standard as 250μg/m3 in 2016. The concentration of TSP in winter was higher than in summer. There was a declining trend for long term as TSP, nitrate and sulfate have higher proportions of TSP's ingredients. The dust fall in Taichung City in 2016 was equally 1.89 ton/square kilometer/month, the graduation was extremely slightly pollute and lower comparing to last year as 3.85 ton/square kilometer/month. 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 achieved above 93% of capture rate. For the portion of hardware repair, the electronic meter was loose in Dajia Station but engineering company has been assigned to repair it; the door of cylinder chamber was blown off but the company has been commissioned to fix it by welding. The older and heavy dust fallout gantry of manuel stations in Beishin middle school was replaced and lifted off for the new dust fall gantry and camet base due to security consideration. In precision machinery park, the display module of billboard was damaged but the company has been commissioned to renew the module. In automatic air quality station, the data was affected between day and night. CO and NO2 were affected by mobile sources of pollution of higher concentration during commuting time, particularly Dali and Zhongming station was obvious; O3 was the result of photochemical at noon time with higher concentration in Dali and Daiping station. In terms of seasonal changing, most of the summer have lower pollutant concentrations, higher in winter and spring; its causes by typical weather patterns in Taiwan such as Typhoons in summer, strong heat convection, good diffusion conditions so the pollutants is not easy for accumulation. The values of O3 were between Mar. to Apr. (spring) and from Sep. to Oct. (autumn) was higher to showing a typical seasonal variation. In automatic station with measured value of long-term trends, SO2 in Taipower's Wuci and Longjing stations were higher concentrations, performing a variety of controlled measurement over the years so SO2 concentration was lower in recent years. NO2 concentration in Zhongming, Dali, and Wufeng station were higher due to mobile sources of pollution; the long-term trend was roughly rendered flat, and Fengyuan station was relocated by the Health Board to Fengyuan high school, NO2 concentration dropped in the case. Most stations of O3 concentration were roughly unchanged in long-term trend. PM10 concentrations were showing a slight downward in long term trend so it meant that efforts over the years for particle control has the achievement. PM2.5 trend is similar to the PM10 in long-term trend that showed a slight downward. In 2016, the ratio with PSI (Pollutant Standards Index) in Fengyuan, Shalu, Tali, Zhongming, Xitun revealing monitoring data from Taiwan Environmental Protection Administration report. The monitoring data is 0.78% in Taichung City from Jan. to Nov. .The higher one was Taichung City standing for 0.78%, followed by Nantou County and Changhua (0.3%). Among Shan, Hai, and Tun, three districts of Taichung City; Shan district had the highest ratio with PSI（0.67％）, followed by Tun (0.55%) and Hai (0.35%) . In the mobile air quality monitoring van, monitoring regularly the implementation of equipment maintenance; based on public petitions and EPA air quality monitoring instruction. It has been completed 18 monitoring until end of Dec.. After monitoring is complete, in addition to submitting the monitoring data and conducting for monitoring data analysis, aggregated monitoring locations near sources may provide reference implementation of planned audit. Monthly monitoring data of the van was achieved more than 90% of capture rate in line with the contract requirements. Mobile air quality monitoring van not only implement air quality monitoring, but also assist the relevant units of the sample collection for total 43 analysis. 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 93%. 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 Fixed Noise Monitoring Station of Second type of stations has higher rate of failure but the Mobile Noise Monitoring Stations were found any failures. Also, 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 Environmental Protection Bureau with the assistance of calculating and uploading the self-evaluation results to Environmental Protection Bureau's Noise Control Information System quarterly.
