本計畫於103年5月20日開始執行，工作內容包含人工監測站操作維護及校正作業、環境音量監測及陳情案件處理、戴奧辛及重金屬空氣品質監測作業、六輕工業區周界敏感區落塵監測作業、氣象站設備維護作業、酸雨自動連續監測設施設置規劃評估及電子看板維護，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，期間儀器採樣運作均正常，並未發生臨時故障而需額外檢修之情形。 (2)已於103年6月17日及103年12月15日完成追溯一級流量校正工作，校正結果迴歸係數R2值為0.9999，符合校正迴歸係數R2值須大於(或)等於0.995規定。 (3)於103年6月24日、103年7月21日、103年10月2日、103年12月23日、104年01月08日及104年04月01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 %，且經最小平方法線性迴歸分析，迴歸係數R2值須大於(或)等於0.995之規定。 (4)每站於上、下旬採樣前與採樣後執行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)於103年7月21日執行計時器校正，校正結果均符合24小時誤差不超過2分鐘之規定。 (6)總懸浮微粒(TSP)部分，監測相對高、低值均發生於口湖金湖國小測站，分別為176 μg/m3及14 μg/m3，各站監測結果均符合空氣品質標準(TSP 24小時值250 μg/m3)；落塵量部分，以北港鎮公所站34.00公噸/平方公里/月為最高，而西螺鎮公所站0.50公噸/平方公里/月為最低。 (7)於104年3月4日~5日配合環保署沙塵訊息發布執行機動性TSP採樣，採樣地點為西螺鎮公所，TSP檢測結果濃度為76 μg/m3，遠低於空氣品質標準(250 μg/m3)，對應同時期之環保署測站PM10測值，除麥寮站88 μg/m3外，其餘測站測值普遍均不高，顯示未受沙塵暴所影響。 (8)環境、道路交通及高鐵音量監測工作已完成128站天，監測結果均符合管制標準；歷年監測結果中，在一般環境音量部分，斗南站由於易受鄰近住戶活動影響，導致部分時段測值容易升高；在道路交通噪音部分，各站均能音量穩定，不易有高值產生。 (9)民眾陳情環境音量部分，累計完成9件次，依陸上運輸系統噪音管制標準，監測結果均未超出管制標準。 (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35場次，共計攔查2,937輛次，針對有噪音之虞之車輛進行檢測105輛次，其中檢測合格77輛次、不合格28輛次、無法檢測7輛次。由於檢測前先經過警察篩選，因此不合格率達27 %，不合格車輛平均超出管制值約4.5分貝。 (12)本縣之一般噪音管制區檢討劃分工作，已於103年12月08日辦理研商會，後續並經公開閱覽1個月後，於104年4月09日依雲林縣政府府環空字第1043612088號函進行公告實施。 (13)環境中非游離輻射電磁波量測共完成極低頻20件及高頻21件，其中極低頻為6件校園電磁場量測及14件低頻非游離輻射電磁波量測，高頻為19件手機基地台及2件民眾陳情手機基地台量測，量測結果遠低於環保署公告之非游離輻射環境建議值。 (14)於崙背國中進行戴奧辛及重金屬採樣作業部分，戴奧辛採樣已執行4點次(103年5月、8月、11月及104年2月)，重金屬採樣執行2點次(103年5月及8月)。在環境戴奧辛部分，測值與環保署歷年於崙背國中檢測數據相比差異不大，且測值於冬春季明顯較高於其餘兩季；重金屬監測結果顯示以鐵、鎂、鋁及鋅等四大類比例較高；汞的檢測部分，與102年度環保署於崙背國小檢測結果比對，本計畫之氣狀汞檢測結果相對較高，而粒狀汞濃度則差異不大，粒狀汞佔氣狀汞比例則較低；六價鉻部分，比對去年度環保署於全國各測點監測之結果，本計畫檢測結果與之差異不大。 (15)六輕工業區周界敏感區落塵監測作業已完成24個落塵量樣品，測值介於42~970 mg/m2 day，以豐安國小10月份測值相對較高。 (16)氣象站設備維護作業已完成60站月，各站狀況大致良好且無損害情形發生，僅於103年8月尚德國小因訊號傳輸不正常，於8月7日進行傳輸模主設備更換。 (17)酸雨自動連續監測設施設置規劃評估作業，依據既有酸雨連續監測設施之位置、陳情敏感區位及與六輕相關之分析，建議優先設置地點為西螺廣興國小，其次為四湖內湖國小。 (18)已完成12次電子看板每月維護工作，播放內容更新部分，已完成76筆。 (19)已完成7站次離島工業區測站功能查核，查核結果全數滿意。 (20)氟化氫連續監測部分，已分別於斗六梅林活動中心(位於斗六富喬南南東方590公尺處)及虎尾農博生態園區(位於虎尾富喬東南方2.17公里處)，各完成至少1個月之連續監測，監測結果均符合固定污染源空氣污染物排放標準之周界標準(60 ppb)。

This project has been started on 20 May 2014 at Yunlin. The project scope included operation, maintenance and calibration of equipment at Air Quality Monitoring Station and Meteorological Station, environmental noise monitoring, dioxin and heavy metal monitoring, dust monitoring at sensitive areas around Sixth Naphtha offshore industrial park, acid rain continuous monitoring station’s design and planning and maintenance of electronic board. The achievements of project were summarized as below: 1) 60 Air Quality Monitoring Station were performed scheduled monthly maintenance. All equipment was under normal operation and no overhaul was required during the project period. 2) Flow rate calibrations were completed on 17 June 2014 and 15 December 2014. The result regression coefficient R2 was 0.9999 which comply with the standard. (R2 shall be larger or equal to 0.995) 3) Multi-point calibrations were performed on 24 June 2014, 21 July 2014, 2 October 2014, 23 December 2014, 8 January 2015 and 1 April 2015. The results were fulfill with the standard requirements including flow accuracy shall be less than 5% difference and regression coefficient R2 shall be larger or equal 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 clock check was performed on 21 July 2014 and fulfilled the standard of less than 2 minutes difference. 6) For TSP monitoring, the highest (175 μg/m3) and lowest (14 μg/m3) concentration were found at chinhu elemetary school station. For dust monitoring, the highest concentration 34 kg/m2 per month was found at Beigang township office station, while the lowest 0.5 kg/m2 per month was recorded at Siluo township office station. 7) On 4 -5 March 2015, according to the sandstorm warning issued by EPA, temporary TSP monitoring was performed at Siluo township office station and recorded concentration of 76 μg/m3 which was far lower than limit (250 μg/m3). At the same period, the PM10 concentrations of other stations were relatively low except the 88μg/m3 at Mailiao station. Hence, it revealed that this area did not affected by sandstorm. 8) Ambient, highway and high speed rail noise monitoring have been performed 128 days and all results fulfilled the limit. According to historical monitoring data, in ambient noise monitoring, as Dounan station was sensitive to nearby residential activities, some intervals were found a high level of noise. In highway noise monitoring, each station were recorded a relatively steady noise level. 9) There were total 9 cases of noise complaints from residents. According to the land transportation noise limit, the monitoring results did not exceed the limit. 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 weekend, the sources would be park visitors and temporary exhibitions. 11) Checking of noise level from vehicles has been performed 35 times and checked 2,937 vehicles. 105 vehicles were requested to perform further noise assessment in which 77 vehicles passed, 28 vehicles unqualified and 7 vehicles unclassified. As selection by police before further assessment, the rate of unqualified was reach 27% and average exceed 4.5 dB of limit. 12) For general noise control area review and division of work, a conference was held on 8 December 2014. After one month public review, it has been put into practice on 9 April 2015 by Yulin government (ref.: 1043612088). 13) Ambient electromagnetic field (EMF) measurement was completed 20 pieces of extremely-low frequency and 21 pieces of high frequency. In which, 6 pieces of extremely-low frequency were performed at school area, 19 pieces of high frequency was performed at phone transmitting station. All the results were within the EPA limit. 14) At Lunbei junior high school station, 4 rounds of ambient dioxin sampling was completed on May, August, November 2014 and February 2015, while 2 rounds of heavy metal sampling was performed on May and August 2014. For ambient dioxin, sampling results were similar with the EPA historical Lunbei elemetary school station data. The results in winter and spring are more distinct than others. For heavy metal monitoring, iron, magnesium, aluminum and zinc were recorded relatively higher concentration. For mercury, comparing with 2013 Lunbei elemetary school station data, gaseous mercury was recorded a relatively higher concentration in this project, while concentration of solid mercury was relatively same. Also, the gaseous mercury had higher proportion to solid state. For chromium VI, sampling results were similar with historical data at all monitoring stations. 15) dust monitoring at sensitive areas around Sixth Naphtha offshore industrial park were completed 24 pieces of samples, ranging 42 -970 mg/m2 per day in concentration. Fengan elemetary school station was recorded relatively high concentration on October. 16) Operation and maintenance of meteorological station has been completed 60 months. Each station was operating normally with no damage. A abnormal signal transmission was recorded at Suntech elemetary school station on August 2014 and replacement of transmitter was performed on 7 August 2014. 17) For new acid rain continuous monitoring station’s design and planning, according to existing location of stations and analysis of relationship between sensitive area and Sixth Naphtha offshore industrial park, it proposed Goang-Shing elementary school as first priority while Sihhu township Neihu Elementary School as second. 18) 12 times of maintenance electronic board and 76 times of content update were recorded. 19) Sixth Naphtha offshore industrial park monitoring station audit were completed 7 times with satisfied result. 20) Hydrogen fluoride continuous monitoring has been perform at least one month at DouLiou MeiLin station(Located 590 meters Douliou fulltech fiber glass corporation South-East)and Yunlin Agriculture Expo parking lot (Located 2.17 km Huwei fulltech fiber glass corporation south-east). All monitoring result were satisfied with the air pollutant emission standard (60ppb).
