本計畫於108年7月3日開始執行，工作內容包含人工監測站操作維護、校正作業及更新1座人工測站設備、環境音量監測及陳情案件處理、監測車環境監測作業、PM2.5連續監測站維護作業、電子看板設備更新及維護、酸雨測站維護、簡易空氣品質監測網監測及空氣品質監測站設置，本報告期間各項工作執行成果，主要如下： 一、人工測站共進行80站月定期維護工作，並完成80站月之TSP採樣工作。 二、已於108年10月18日完成孔口流量計之追溯一級流量校正工作，校正結果迴歸相關係數為0.9999，符合校正回歸線性相關係數應大於0.999之規定。 三、於108年7月、10月及109年1月各進行1次高量採樣器多點校正，校正結果均符合每一流量準確度誤差不得超過5 %，且多點校正回歸線性相關係數須大於0.995之規定。 四、每站於每月上、下旬採樣前與採樣後各執行1次高量採樣器單點校正，流量準確度均符合誤差不得超過7 %之規定。 五、總懸浮微粒(TSP)：各測站間以北港站之幾何平均值63 μg/m3為最高，口湖站之幾何平均值46 μg/m3為最低，監測相對高值發生於口湖站為167 μg/m3，因整體趨勢起伏一致，故研判因大氣影響；各月幾何平均值部分，以109年1月相對較高。各站監測結果均符合空氣品質標準(TSP 24小時值250 μg/m3)。 六、落塵量：各測站間以北港站之平均值2.22公噸/平方公里/月為最高，口湖站之平均值1.65公噸/平方公里/月為最低。各測站測值部分，以108年9月份北港站4.78公噸/平方公里/月為最高，而108年12月份口湖站0.58公噸/平方公里/月為最低。 七、一般地區環境音量及道路交通噪音音量監測工作共計完成60站天，監測結果均符合管制標準；歷年監測結果中，一般地區環境音量歷年監測時較易有高值產生，道路交通音量歷年監測因較少外在因素干擾，歷年測值較為平穩。 八、已完成8次固定式噪音站維護作業，而監測結果部分，平日日間時段容易受到上下班車流量及不定期枝葉雜草修整作業影響，而假日則多為鄰近人文公園遊客數增加及活動舉辦。 九、機動車輛噪音檢測作業已完成32場次，攔查總計1,496輛次，針對有噪音之虞之車輛進行檢測19輛次，其中檢測合格16輛次、不合格3輛次，不合格率為16%，不合格車輛平均超出管制值約4.3分貝。 十、執行斗六工業區及環境調查濃度水準(大埤鄉、古坑鄉、西螺鎮、林內鄉、虎尾鎮)，完成9站天監測。監測結果皆符合空氣品質標準，僅部分監測期間O3濃度最大八小時平均值具有高峰值。 十一、PM2.5連續監測站維護作業已完成16站月，測站狀況良好，持續監測中。 十二、已完成8次電子看板每月維護工作，播放內容更新部分，已完成83筆。 十三、酸雨測站定期操作維護工作，已完成8站月，測站狀況良好，持續監測中。 十四、維持斗六工業區30個簡易空氣品質監測站及2套風向風速計正常運轉，每月資料獲取率為85 %以上。 十五、雲林縣自設測站自108年12月18日起於虎尾平和國小辦理試運轉，至109年1月17日止，共計試運轉31日。該測站於109年2月18日搬移至虎尾國民小學。

This project started from 3rd July, 2019, and its contents included operation, maintenance and calibration of the manual monitoring station, 1 station’s equipment renewal, environmental noise monitoring, petitionary cases handling, environmental monitoring by monitoring car, maintenance of the PM2.5 continuous monitoring stations, renewal and maintenance of the digital signage, maintenance of the acid rain monitoring stations, monitoring of the Simple Air Quality Monitoring network, and establishment of the air quality monitoring station. The achievements in this project were summarized as bellow: 一、Completing 80 times maintenance works on manual monitoring stations, and 80 times TSP sampling. 二、Completing the flow meter’s calibration on 18th October, 2019. The regression coefficient was 0.9999, which was complied with the standard. (The regression coefficient shall be larger than 0.999) 三、Completing multiple points’ calibration on samplers in July, October (2019) and January (2020). All results were complied with the standard. (The flow accuracy bias shall be less than 5%; The regression coefficient shall be larger than 0.995) 四、Completing one point’s sampler calibration in the beginning of month (before and after sampling) and the end of month (before and after sampling), and the flow accuracy was complied with the standard that the bias shall be less than 7%. 五、TSP: The highest geometric average was happened in Beigang (63 μg/m3), and the lowest was in Kouhu (46 μg/m3). The monitoring relative high value was happened in Kouhu (167 μg/m3). Due to the comparing trend was consistent, the results were affected by the atmosphere. In the monthly geometric average, January, 2020, was the highest. All monitoring results were fit to the air quality standard. (TSP 24 hour 250 μg/m3) 六、Dust Fall: The highest average was happened in Beigang (2.22 ton/km2/month) and the lowest was happened in Kouhu (1.65 ton/km2/month). In monitoring value, the highest number was happened in Beigang (4.78 ton/km2/month) in September, 2019, and the lowest was happened in Kouhu (0.58 ton/km2/month) in December, 2019. 七、Completing 60 days general areas environmental and road traffic noise volume monitoring, all results were fit to the standard. According to the historic monitoring data, it was easier to detect high value in general areas environmental volume monitoring. And road traffic volume was stable due to less disturbance. 八、Completing 8 times fixed noise monitoring stations’ maintenance. In monitoring result, it was affected by the high-flow of vehicles and gardening in weekdays; for weekend, it was affected by the tourists and activities from nearby parks. 九、Completing 32 times mobile vehicles noise detecting, total intercepted number was 1,496. Furthermore, undertaking examining on 19 vehicles, 16 of them were qualified, 3 were unqualified (the average exceeded 4.3 dB), the unqualified rate was 16%. 十、Completing 9 days monitoring on the Douliu Industrial Park and nearby environment (Dapi, Gukeng, Hsilo, Linnei, Huwei), all results were met to the air quality standard, but only O3 eight hours average had high peak. 十一、Completing 16 times maintenance on PM2.5 continuous monitoring stations, all stations were in good condition, and the monitoring was continued. 十二、Completing 8 times maintenance on digital signage; 83 updates on broadcasting contents had been completed. 十三、Completing 8 times routine maintenance on acid rain stations, all stations were in good condition, and the monitoring was continued. 十四、Maintaining 30 simple air quality monitoring stations and 2 wind meters in the Douliu Industrial Park, the month data acquiring rate was over 85%. 十五、The Yunlin County’s monitoring station had been operated in the Ping-He elementary school on 18th December, 2019, and stopped testing on 17th January, 2020 (total was 31 days). The station was moved to the Hu-Wei elementary school on 18th February, 2020.
