中文摘要 | 本研究於屏東市區選取三處工地及一個內埔地區鄉村測站,共設置四個懸浮微粒採樣站,分別為道路挖埋管線、校園綠化整地、鄰近道路之大樓建築施工及靠近內埔工業區附近之鄉村測站。於工程施工期間以高量採樣器及粒徑分析儀(MOUDI),分別使用玻璃纖維和石英濾紙採集附近空氣,並進行粒徑分佈及成份分析,以探討各工程施工對空氣品質影響之程度。 調查結果發現,各工程施工階段,懸浮微粒粒徑分佈呈三峰或雙峰分佈,最高峰值介於氣重粒徑5.6~10μm,偏向於粗顆粒。而道路挖埋管線施工時,對空氣品質影響最大。 本研究選取各測站空氣樣本,以ICP-AES儀器進行重金屬成份分析,結果顯示,各測站TSP中重金屬成份以Fe、Zn、Pb、Mn濃度較高,而Ni、Cr、Cd濃度較低,故可知道路及營建施工產生之灰塵對重金屬Fe貢獻量最大。 |
英文摘要 | In this study, four sites were selected, three building sites and one in Ne-Pu country. Each of the samples were taken during construction. The Ne-Pu country samples were taken for reference, because it has less air pollution. Both samples were taken with a high volume air sampler and with a MOUDI sampler that has eight cascade impact stages, it was used to collect the suspended particulate matter in the ambient air. These samples were collected for particle size and heavy metal content analysis, in order to investigate the relationship between building construction and air pollution. According to the statistical results of the particle size distribution, the maximum aerodynamic particle size (5.6~10μm) were dominate by coarse particle fraction. All TSP samples were analyzed by ICP-AES. Seven elements were studied, among these Fe, Zn, Pb, Mn concentrations were higher while Ni, Cr, Cd were much lower in contents. High concentrations of iron and manganese contributed by building sites or road sites were found by many articles as “target elements” from soils. |
