臺灣博碩士論文加值系統

本論文主要目的是研究季節與傳輸路徑，對大氣中微粒化學特徵的影響及東亞沙塵暴大氣微粒金屬指標。前段部分，探討台灣西部海岸地區PM2.5與PM2.5-10微粒上金屬季節性變化與傳輸路徑之化學特徵。微粒採樣從2009年3月到2010年2月，以ICP及ICP-MS分析PM2.5及PM2.5-10中16個金屬元素。多種方法、逆軌跡分析、富集因子與主成分分析用來鑑定微粒上金屬元素可能來源。PM2.5與PM2.5-10年平均質量濃度分別是34.9±20.6及20.8±11.3 μg m-3。PM2.5及PM2.5-10微量金屬最高值濃度出現在冬季，PM2.5-10上主要金屬元素最高值則出現在秋季。富集因子結果顯示PM2.5及PM2.5-10上的銅、砷、鋅、鉛、鎘及硒為人為來源。主成分分析結果顯示，來自當地及鄰近地區的交通、煤及重油燃燒為研究地區主要的人為來源。逆軌跡分析顯示來自大陸的東北季風 (冬季) 展現與來自東南亞地區的西南季風 (夏季) 有不同的化學特徵。值得注意，即時在相同季節，不同的長程傳輸路徑，會影響微粒上金屬濃度及與金屬相關的總過量致癌風險。
2010年2月至3月東亞沙塵暴期間，在台灣南部研究大氣中粒狀物及18種金屬元素，在四種顆粒相的變異性。PM2.5、PM2.5-10、PM10及TSP四種顆粒相平均質量濃度變化，在亞洲沙塵暴期間以PM2.5-10為主，非沙塵暴期間則以PM2.5 為主。地殼元素 (鐵、鎂、鍶、鈷、鋇及錳)於亞洲沙塵暴及非沙塵暴期間展現明顯的差異，故這些元素可用來當作沙塵暴入侵指標；除了鈣及鋁元素外。在微粒質量及金屬濃度變化，PM2.5-10顆粒相可以清楚區分出亞洲沙塵暴及非沙塵暴。富集因子顯示大部分人為金屬元素，在沙塵暴期間明顯低於非沙塵暴期間。此外，粗顆粒相的人為金屬元素富集因子也可做為沙塵暴入侵指標。除了傳輸路徑外，沙塵暴對受體影響的程度和滯留時間也有相關。

The main goal of this dissertation was to investigate the effect of seasonality and transport route on chemical characteristics and marks of East Asian dust storms in ambient particulate matter. In first part, this study investigated seasonal variations and transport route in PM2.5 and PM2.5-10 associated metallic elements in the western coastal area of southern Taiwan. Particle sampling was conducted from March 2009 to February 2010. Sixteen metallic elements in PM2.5 and PM2.5-10 were determined by ICP and ICP-MS. Multiple approaches, backward trajectory analysis, enrichment factor (EFc), and principal component analysis (PCA), were used to identify the potential sources of the metallic elements. The annual mean concentrations of PM2.5 and PM2.5-10 were 34.9±20.6 and 20.8±11.3 μg m-3, respectively. Analysis of the temporal distribution revealed seasonal peaks for most of the trace elements in PM2.5 and PM2.5-10 during winter season and the major elements in PM2.5-10 during the autumn season. EFc results confirmed that the main contributors of Cu, As, Zn, Pb, Cd, and Se were anthropogenic sources in PM2.5 and PM2.5-10. PCA identified traffic emissions, coal, and heavy oil combustion from both local and neighboring areas, as the major anthropogenic sourcesin the sampling site. With backward trajectory analysis, northeast monsoon (winter) originated from China demonstrated different chemical characteristics from those of southwest monsoon (summer) from the Southeast Asian countries. It is noted that even in the same season, route-dependent effects of long-range transport in metallic concentrations and total excess cancer risk (ECR) of health-related metals were observed.
In the mark study of East Asian dust storms, the variationsin particulate matter (PM) and in eighteen metallic elements in four different particle sizes in the air of southern Taiwan were investigated from February to March 2010. The variation inmean mass concentrations of PM2.5, PM2.5-10, PM10, and TSP between Asian dust storm (ADS) and non-dust storm (NDS) periods suggested that the dominant fractions were PM2.5-10 and PM2.5, respectively. The obvious differences in metallic element concentrations between ADS and NDS periods suggested that crustal elements (Fe, Mg, Sr, Co, Ba and Mn) can be used as dust storm indicators, in addition to Ca and Al. Both mass fractions and metallic concentration ratios indicated that the PM2.5-10 fraction can distinguish between ADS and NDS periods. An enrichment factor (EFc) demonstrated that most anthropogenic elements were significantly lower in ADS periods than in NDS periods. The EFc values for anthropogenic elements in coarse particles may be used as indicators of dust storm invasion as well. An association was found between the extent of dust storm effects on receptors and the residence time (duration) of the event, in addition to the transport pathway.
