本計畫於107年12月7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、電子看板設備維護、酸雨測站維護及簡易空氣品質監測網監測，本報告期間各項工作執行成果，主要如下： (1)人工測站共進行60站月定期維護工作，並完成60站月之TSP採樣工作。 (2)已於107年12月28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。 (3)於108年1月8日及4月10日進行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。 (4)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。 (5)完成西螺鎮公所人工測站設備更新(包含高量採樣器、穩壓器及落塵架)，在更新前，其誤差大多介於1.01-2.72(%)，更新後誤差為0.08-0.85(%)，顯示更新後誤差明顯變小；此外，更新設備亦可使採樣過程更為順暢，減少人力與時間的耗損。 (6)總懸浮微粒(TSP)：各站監測結果均符合空氣品質標準(TSP 24小時值250 μg/m3)。各測站間以北港鎮公所站之幾何平均值57 μg/m3為最高，口湖金湖國小站之幾何平均值39 μg/m3為最低，監測相對高值發生於北港鎮公所測站為110 μg/m3，因北港鎮公所附近有農田整地及播種揚塵，導致濃度相對較高。 (7)落塵量：口湖金湖國小站之平均值9.04公噸/平方公里/月為最高，虎尾衛生所站之平均值2.85公噸/平方公里/月為最低。各測站測值部分，以108年2月份西螺鎮公所站26.60公噸/平方公里/月為最高，而107年12月份西螺鎮公所站0.22公噸/平方公里/月為最低。 (8)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40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，測值離散程度明顯較為集中。 (9)已完成6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。 (10)機動車輛噪音檢測作業已完成21場次，攔查總計621輛次，另針對有噪音之虞之車輛進行檢測20輛次，其中檢測合格15輛次、不合格5輛次。由於檢測前先經過警察篩選，因此不合格率為25%，不合格車輛平均超出管制值約3.8分貝。 (11)已於斗六工業區、雲林科技工業區周界區域及斗南鎮環境調查完成6站天移動式監測車空氣品質監測，監測結果均符合空氣品質標準，唯獨臭氧有兩次因受到大氣環境影響而高於最大八小時平均值。 (12)PM2.5連續監測站維護作業已完成12站月，測站狀況良好，持續監測中。 (13)已完成6次電子看板每月維護工作，播放內容更新部分，已完成47筆。 (14)酸雨測站定期操作維護工作，已完成6站月，測站狀況良好，持續監測中。 (15)維持斗六工業區32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。

Summary： This project has started since 7th December, 2018. The project scope included operation, maintenance and calibration of equipment at Air Quality Monitoring Station and renewal of the equipment of one station; noise monitoring and case handling; mobile van monitoring; maintenance of PM2.5 continuous monitoring stations; maintenance of digital signage; maintenance of acid rain stations and monitoring of Simple Air Quality Monitoring network. The achievements of project were summarized as below: 1)60 Air Quality Monitoring Station were performed scheduled monthly maintenance and 60 TSP samples had been completed. 2)Flow rate calibrations were completed on 28th December, 2018. The result regression coefficient was 0.9999 which comply with the standard. (The regression coefficient shall be larger to 0.999) 3)Multi-point calibrations were performed on 8th January 2019, 10th April 2019. The results were fulfill with the standard requirements including flow accuracy shall be less than 5 % difference and regression coefficient shall be larger to 0.995. 4)Every half of the month, one point calibrations were performed before and after sampling at each station. The flow accuracy shall be less than 7% difference. 5)The equipment of Xiluo Air Quality Monitoring Station had renewed, including high volume samplers, voltage regulators and dust sampling platform. Before the update, the error was mostly between 1.01-2.72 (%), and the error after update was 0.08-0.85 (%), indicating that the error after update was significantly smaller. In addition, the update device could make the sampling process smoother and reduced the manpower and time consumption. 6)TSP：The monitoring results at all stations met the air quality standards(TSP 24 hour 250 μg/m3). The highest(57 μg/m3) geometric average concentration was found at Beigang station. And the lowest(39 μg/m3) geometric average concentration was found at Jinhu station. During the monitoring period, high values(110 μg/m3) were discovered at Beigang Station because of the consolidation of farmland and the cultivation of crops next to Beigang Station, resulting in higher concentrations. 7)Dustfall：The highest(9.04 ton/km2/month) average concentration was found at Jinhu station. And the lowest(2.85 ton/km2/month) average concentration was found at Huwei station. Among the single station monitoring values, the highest value was found in Xiluo Station in February 2019, and the lowest value was found in Xiluo Station in December 2018. 8)Ambient and traffic noise monitoring have been performed 40 days and all results fulfilled the limit. According to historical monitoring data, in ambient noise monitoring was easier to detect high values. In traffic noise monitoring, monitoring values were more concentrated because they were less disturbed by external factors. 9)6 times maintenances were completed at fixed noise monitoring station. The sources of noise were proposed. During weekdays, the noise would be come from high flow of vehicles at peak periods and operation of machine during gardening. During the weekend, the sources would be park visitors and temporary exhibitions. 10)Checking of noise level from vehicles has been performed 21 times and checked 621 vehicles. 20 vehicles were requested to perform further noise assessment in which 15 vehicles passed and 5 vehicles unqualified. As selection by police before further assessment, the rate of unqualified was reach 25 % and average exceed 3.8 dB of limit. 11)Completed 6-day mobile van air quality monitoring in Douliu Industrial Park, surrounding area of Yunlin Technology-based Industrial Park and surrounding area of Dounan Town. The monitoring results met the air quality standards, except that ozone had twice been affected by the atmospheric environment and was above the maximum eight-hour average. 12)Completed the maintenance works of 12 PM2.5 continuous monitoring stations. The stations are in good conditions, and monitoring is kept going. 13)Implemented 6-time monthly maintenance on digital signage. 47 updates on broadcasting content had been completed. 14)Implemented 6-time monthly maintenance on the Xiluo acid rain station. The station is in good condition, and monitoring is kept going. 15)Maintained 32 simple air quality monitoring stations and 2 sets of anemometers in Douliu Industrial Park, and Monthly data capture rate was over 85 %.
