中文摘要 | 本研究採用化學質量平衡法釐清細微粒之主要污染來源,藉以探討高雄都會區空氣品質不良之原因。本研究於民國88年1月、2月及5月在高雄市前鎮空氣品質測站進行PM2.5密集採樣,並同步實施氣象量測。採樣後之濾紙則進行懸浮微粒化學成份分析,分析項目包括離子成份、金屬成份及碳成份等。本研究以主成份因子分析法進行污染源之定性分析,篩選出主要微粒污染源,再將其應用於化學質量平衡受體模式,藉以定量分析污染源之貢獻量。由主成份因子分析法定性分析結果得知,前鎮測地PM2.5主要污染來源為地殼元素物質為主之相關污染源(如:道路揚塵或營建工程逸散揚塵)、交通污染源、二次衍生性氣膠、燃煤電廠等。而由化學質量平衡受體模式之定量分析結果得知,大氣中PM2.5之主要來源為交通污染源與二次衍生性氣膠。 |
英文摘要 | Intensive seasonal sampling campaigns were undertaken at an urban location in Kaohsiung, Taiwan, in which ambient particulate matter was sampled by dichotomous samplers and mteorological conditions were monitored simultaneously as well. The dichotomous sampler enabled the collection of suspended particulate matter representative of fine (diameter<2.5 μm) and coarse sized (2.5μm~10μm) fractions. The samples have been analyzed for a wide range of metallic constituents, elemental carbon and organic carbon, and the soluble ions, such as Cl-, SO42-, NO-3, NH4+, CA2+, Na+, K+, etc. A receptor modeling study has been conducted using Principal component Factor Analysis (PCA) followed by Chemical Mass Balance model (CMB) in order to identify potential emission sources and the source apportionment of PM2.5 in metro Kaohsiung. The results from PCA demonstrate that geological material related sources, motor vehicle exhaust, secondary aerosols and coal-fired power plant are found to correspond closely to PM2.5. meanwhile, according to the results obtained from CMB, motor vehicle exhaust and secondary aerosols are shown to be the major contributors of PM2.5 in the Kaohsiung metropolitan area, although other sources such as metals processing, petroleum industry and coal-fired power plant also contribute. |
