105年臺中市細懸浮微粒(PM2.5)採樣分析計畫
| 中文摘要 | 本計畫以採樣分析為主，工作包含周界、管道以及廚房的PM2.5採樣，檢測中部科學園區有害空氣污染物，透過計畫執行取得正確、可信賴的環境監測數據，提供本市管制策略研擬之依據。 每 6 天一次的周界PM2.5手動採樣結果顯示，在四站中(梧棲、后里、西屯、大里)以大里手動測站PM2.5不符合空氣品質標準 (24小時值平均35μg/m3)比例最高。PM2.5成分分析顯示，后里及梧棲手動測站以硫酸鹽(SO42-)濃度較高，西屯及大里手動測站則以有機碳(OC)比例最高。 管道PM2.5檢測結果顯示；台中電廠燃煤鍋爐排放FPM濃度1.42mg/Nm3，CPM濃度13.9mg/Nm3；中龍鋼鐵高爐氣鍋爐FPM濃度排放0.28mg/Nm3，CPM濃度5.07mg/Nm3；宏全國際燃重油鍋爐排放FPM濃度34.2mg/Nm3，CPM濃度78.9mg/Nm3。歷年檢測結果歸納顯示，無防制設備的燃重油鍋爐排放高濃度FPM及CPM。 本年度中部科學園區有害空氣污染物檢測結果顯示，各種管制物種的濃度均遠低於該物種之管制標準。揮發性有機物台中基地87.1μg/m3，后里基地71.5 μg/m3，物種中以丙酮、甲苯及甲醇濃度較高；酸性氣體濃度台中基地18.01 μg/m3，后里基地17.73μg/m3。 本計畫建議優先改善燃油鍋爐排放高濃度PM2..5的問題，在本市PM2.5高污染期間，各區實施交通源減排措施最有利污染下降，對固定源管制可規劃要求燃煤鍋爐及電弧爐減排，逸散源方面在春季加強農廢禁燒管制，秋季加嚴營建工程、裸露地逸散管理並輔以洗掃街。 | ||

Sampling Analysis of Fine Particulate Matter(PM2.5) of Taichung City in 2016
| 英文摘要 | This study is mainly based on sampling analysis, including PM2.5 sampling of the perimeters, in-stack and kitchens, and monitoring hazardous air pollutants in Central Taiwan Science Park. With the implementation of this study, we have been able to obtain accurate and reliable environmental data, providing a basis for strategical development and practice for the municipality. The results of manual sampling of PM2.5 once every six days showed that out of the four stations (Wuqi, Houli, Xitun and Dali), PM2.5 in Dali’s manual monitor station did not meet air quality standards (24 hour average of 35μg/m3) with the highest concentration. PM2.5 composition analyses showed that Houli and Wuqi stations had higher concentrations of sulfate (SO42-), while Xitun and Dali’s stations had highest concentrations of organic carbon (OC). Results of PM2.5 monitor of in-stack showed: concentrations of emissions from Taichung Power Plant coal-fired boilers were FPM 1.42mg/Nm3, CPM 13.9mg/Nm3; concentrations of emissions from Dragon Steel Plant blast furnace gas boilers were FPM 0.28mg/Nm3, CPM 5.07mg/Nm3; concentrations of emissions from Hon Chuan Enterprise Plant oil boilers were FPM 34.2mg/Nm3, CPM 78.9mg/Nm3. Analysis of historical monitored results showed that oil-fueled boilers with no control equipment had higher concentrations of FPM and CPM emissions. Results of monitoring hazardous air pollutants in Central Taiwan Science Park showed that concentrations of controlled pollutants were much lower than regulatory standards. Concentrations of volatile organic compound at the Taichung site were 87.1μg/m3, and 71.5μg/m3 at the Houli site; acetone, toluene and methanol pollutants had higher concentrations; concentrations of inorganic acids at the Taichung site were 18.01 μg/m3, and 17.73μg/m3 at the Houli site. This study recommends that priority should be given to the improvement of PM2.5 emissions from oil-fuel boilers. During high PM2.5 pollution periods, reducing traffic emissions in each area is most effective in reducing pollutant emissions. For control of stationary emissions, emission reduction for coal-fired boilers and electric arc furnaces should be required. For fugitive emissions, it is recommended to implement regulation of burning of agricultural waste in the spring season, as well as strict control of construction, management of fugitive emissions from exposed sites complemented with street sprinkling in the autumn season. | ||
