本計畫於106年11月11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、氣象站設備維護作業、電子看板設備更新及維護、離島工業區測站功能查核、酸雨測站維護及簡易空氣品質監測網設置，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120站月之TSP採樣工作。 (2)已於107年1月2日完成追溯一級流量校正工作，校正結果迴歸相關係數為0.9999，符合校正迴歸相關係數應大於0.999規定。 (3)於107年1月10日、4月11日、7月5日及10月3日各進行1次多點校正，校正結果均符合每一流量準確度誤差不得超過5 %，且多點校正迴歸相關係數值須大於0.995。 (4)每站於每月上、下旬採樣前與採樣後各執行1次單點校正，流量準確度均符合誤差不得超過7 %之規定。 (5)總懸浮微粒(TSP)：各測站間以虎尾鎮衛生所及北港鎮公所站之幾何平均值57 μg/m3為最高，古坑東和國中站之幾何平均值42 μg/m3為最低，各站監測結果均符合空氣品質標準(TSP 24小時值250 μg/m3)；幾何平均值部分，歷年均低於空氣品質標準年幾何平均值130 μg/m3，且自102年起，有逐漸下降的趨勢。 (6)落塵量：各測站間以西螺鎮公所之平均值2.92公噸/平方公里/月為最高，古坑東和國中站之平均值1.29公噸/平方公里/月為最低；年平均值部分，各年度平均測值以106年2.54公噸/平方公里/月最低，104年14.05公噸/平方公里/月為最高，而105年測值平均為6.02公噸/平方公里/月，相較於近年監測結果，有呈現降低的趨勢。 (7)與鄰近縣市比對部分(中彰投、雲嘉南及高屏空品區各縣市)，各縣市之TSP趨勢大抵一致，惟高雄市較於其他縣市有偏高趨勢，各月平均值以高雄市112 μg/m3(106年12月)為相對較高，而雲林縣13 μg/m3(107年8月)及彰化縣18 μg/m3(107年6月)為相對較低；各縣市之落塵趨勢無一致性，以高雄市30.40公噸/平方公里/月(106年12月)為最高，彰化縣0.12公噸/平方公里/月(107年6月)為最低。 (8)已完成更新1座人工測站設備，包含高量採樣器、穩壓器及落塵採樣平台。 (9)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80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。 (10)已完成12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。 (11)機動車輛噪音檢測作業已完成42場次，攔查總計1,407輛次，另針對有噪音之虞之車輛進行檢測44輛次，其中檢測合格20輛次、不合格10輛次、無法檢測14輛次。其中因現場查無車籍資料或車況不佳等因素，導致無法於現場檢測之車輛，將擇期通知到檢，由於檢測前先經過警察篩選，因此不合格率為33 %，不合格車輛平均超出管制值約3.87分貝。 (12)環境中非游離輻射電磁波量測共完成1件射頻手機基地台及39件極低頻落地型變壓器電磁波量測，其中射頻最高為0.00443 mW/cm2，低頻最高為7.417毫高斯，最低為1.651毫高斯，量測結果均遠低於環保署公告之非游離輻射環境建議值(射頻0.455 mW/cm2及極低頻833毫高斯)。 (13)已完成2套電子仿鞭炮機購置與點交。 (14)已於斗六工業區及雲林科技工業區周界區域完成12站天移動式監測車空氣品質監測，歷次監測結果除梅林福德宮107年4月30日至5月1日及107年10月15日至16日臭氧最大八小時平均值超過標準其餘測項均符合空氣品質標準，另與同時段之環保署斗六測站臭氧最大八小時平均值分別為69.0及65.3 ppb，亦為超標，屬整體空品變化趨勢，而非局部性影響。 (15)PM2.5連續監測站維護作業已完成24站月，測站狀況良好，持續監測中。 (16)氣象站設備維護作業已完成60站月，有關風速風向計及二氧化碳偵測器之狀況，目前有2站(新興國小、六輕南門宿舍)風速風向計及3站(新興國小、六輕南門宿舍、施厝活動中心)二氧化碳偵測器採用替代設備。 (17)已完成1座LED顯示看板暨連線系統更新作業並執行12次電子看板每月維護工作，播放內容更新部分，已完成81筆。 (18)已完成2站離島工業區測站功能查核，查核測站為東勢站及土庫站，查核結果全數滿意。 (19)酸雨測站定期操作維護工作，已完成雙週維護(26次)、月維護(12次)、每季維護(4次)作業。 (20)已於斗六工業區完成布建32個簡易空氣品質監測站及2套風向風速計並完成9月次監測作業，所有作業皆依工作進度進行。

This project has started since November 11th, 2017. 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 equipment at meteorological stations; ●update and maintenance of digital signage; ●functional audits of stations in offshore industrial park; ●maintenance of acid rain stations and setting up 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 120 TSP samples had been completed. 2)Flow rate calibrations were completed on 2nd January 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 10 January 2018, 11 April 2018, 5 July 2018 and 3 October 2018. 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)TSP：The highest(57μg/m3) geometric average concentration were found at Huwei station and Beigang station. And the lowest(42μg/m3) geometric average concentration were found at Gukeng station.The monitoring results at all stations met the air quality standards(TSP 24 hour 250 μg/m3). The geometric mean over the years were below the air quality standards(130 μg/m3), and since 2013, there was a gradual downward trend. 6)Dustfall：The highest(2.92 ton/km2/month) and lowest(1.29 ton/km2/month) average concentration were found at Hsilo station and Gukeng station. In the annual average, the average annual measured value was the lowest in 2017 at 2.54 ton/km2/month and the highest in 2015 at 14.05 ton/km2/month. The average measured value in 2016 was 6.02 ton/km2/month, showing a decreasing trend compared with the monitoring results in recent years. 7)Compared with the corresponding sections of neighboring counties (Taichung, Changhua, Nantou, Chiayi, Tainan, Kaohsiung and Pingtung), the trends of TSP in all counties and cities were approximately the same, but the Kaohsiung City had a higher tendency than other counties and cities. Among the monthly averages, Kaohsiung City had the highest value of 112 μg/m3 in December 2017. The lowest value of 13 μg/m3 in Yunlin County (August 2018) and 18 μg/m3 in Changhua County (June 2018). The Dustfall in counties and cities did not have the same trend. The highest was 30.40 ton/km2/month (December 2017) in Kaohsiung City and the lowest was 0.12 ton/km2/month (June 2018) in Changhua County 8)The equipment of one Air Quality Monitoring Station had renewed, including high volume samplers, voltage regulators and dust sampling platform. 9)Ambient and traffic noise monitoring have been performed 80 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. 10)12 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. 11)Checking of noise level from vehicles has been performed 42 times and checked 1,407 vehicles. 44 vehicles were requested to perform further noise assessment in which 20 vehicles passed, 10 vehicles unqualified and 14 vehicles unclassified. Among vehicles that can't be inspected on site due to factors such as lack of vehicle information or bad condition on the spot will be notified to the inspection. As selection by police before further assessment, the rate of unqualified was reach 33 % and average exceed 3.87 dB of limit. 12)Completed measurement of non-ionizing electromagnetic radiations of 1 mobile phone platform during which 0.0044 mW/cm2 was the highest result recorded, and 39 ultra-low frequency floor-type transformers with 7.417mG and 1.651mG recorded as the highest and lowest frequencies. Results were way below the suggested non-ionizing electromagnetic radiations values (0.455mW/cm2 in radio frequency and 833mG in ultra-low frequency) under the EPA Notice. 13)Had completed two sets of electronic firecracker purchase and delivery. 14)Completed 12-day mobile van air quality monitoring in Douliu Industrial Park and surrounding area of Yunlin Technology-based Industrial Park. All measurements complied with the air quality objective of 8-hourly average of ozone emission except the measurements from 30 Apr, 2018 to 1 May, 2018 and 15 Oct, 2018 to 16 Oct, 2018 at Fudegong, Meilin. Measurements under the same period of time at Douliu station also exceeded the limit, during which 69.0ppb and 65.3ppb were the highest values measured respectively in the two periods, indicating a widespread deterioration of air quality. 15)Completed the maintenance works of 24 PM2.5 continuous monitoring stations. The stations are in good conditions, and monitoring is kept going. 16)Completed maintenance works of equipment at 60 meteorological stations. Standby wind sensors are being used at Sin-sing Elementary School and Liuhing Nanmen, and standby carbon dioxide detectors are being used at Sin-sing Elementary School, Liuhing Nanmen and Siyi Activity Centre. 17)Completed connection system update for 1 LED digital signage, and implemented 12-time monthly maintenance on digital signage. 81 updates on broadcasting content had been completed. 18)Completed functional audits for 2 stations (Tungshih Station ＆ Tuku Station) in offshore industrial park. Audit results were satisfactory. 19)Completed 26 times bi-weekly maintenance, 12 times monthly maintenance and 4 times quarterly maintenance for acid rain stations. 20)Completed building of 32 simple air quality monitoring stations and 2 sets of anemometers in Douliu Industrial Park, and 9 monitoring works had been completed by far. All works are being carried out in accordance with schedule.
