營建工地周界PM10之排放特性及其管理上應用之研究
Characteristics of PM10 Emitted from Construction Sites and Applied to Management
摘要
本研究目的在探討不同營建工程類別工地周界懸浮微粒PM10的污染排放量特性分析，研擬相關管制規範及訂定合乎現況減量目標之標準。進行之營建工程周界粒狀污染物之採樣分析，依工程類別分類，選擇6處不同典型營建工地作為檢測目標，各類至少選取三個代表工地，每一工地至少進行4次懸浮微粒之PM10採樣分析，以檢測比對逸散污染排放情形，檢測結果得知管線工程為155.3-361.3µg/Nm3，橋樑工程為72.5-311.6µg/Nm3，其他工程類則為63.7-259.3 µg/Nm3，區域開發工程37.5-202.4µg/Nm3，道路工程為28.4-121.9µg/Nm3，建築工程之濃度為20.3-79.2µg/Nm3。 研究結果顯示，風速會增加塵土顆粒動量改變土質中坋土負荷量之外擴，易導致部分工程類別的污染排放濃度變大，而六種工程類型之檢測排放量大小與受開挖裸露面是否有防塵措施及車輛揚塵等影響因素有關，且與工地內已作好防塵措施準備及早因應有明顯差異效果。 根據本研究實驗排放特性分析，初擬『營建工地周界PM10標準』研訂兩種方案：甲方案：以工地周界最高值與最低值之差值超過125μg/Nm3為標準。乙方案：以工地周界至少四點之日平均值超過125μg/Nm3為標準，可適用於土木營建業等行業。對於工程規模太小或部分空品涵容量較高地區得免予管制。

The purposes of the research are to discuss different construction sites of Suspended Particulates (PM10) emission characteristics and strategies for emission control. Three represented building site each in six different building types, or 18 buildings totally, are chosen to measure PM10 analysis at least 4 times to analyze the emission characteristics. PM10 for the pipeline are 155.3-361.3µg/Nm3, for the bridge construction are 72.5-311.6 µg/Nm3, for other constructions are 63.7-259.3 µg/Nm3, for regional developed project are 37.5-202.4 µg/Nm3, for the road engineering are 28.4-121.9µg/Nm3, and for the under-constructed building are 20.3-79.2 µg/Nm3. The result of study shows increase of wind speed can increase the fugitive dust, resulting in significant changes of working procedures. An appropriate dustproof measures are capable of prevent fugitive dust for these six different building types caused by the wind. Two standard procedures are proposed: first of all, the differences between highest and lowest values cannot exceed 125 µg/Nm3. Secondly, the average results for the 4 data in a site cannot exceed 125 µg/Nm3. These standards are suitable for any construction industry except for the small constriction site.
