本研究主要分析台灣西南沿海沉積物中多環芳香烴濃度分佈與推估來源。台灣西南沿海著重工業，沿岸有數十個工業區、加工出口區、煉鋼廠、煉油廠、造船廠、興達遠洋漁港、興達火力發電廠、高雄國際港等。數十年來經濟成長快速、工業發達帶來繁榮與進步，但污染卻日趨嚴重，使得廢水經過河川或放流管進入海洋中，或是大氣沉降入海，使海洋直接或間接承受相當大的污染量。
本研究探討台灣西南沿海沉積物中多環芳香烴的含量結果發現其總量介於197.3~2498.9（ng /g -dw）間，平均值為912.0（ng /g -dw）。以測站總濃度來看，測站A3在高雄第一港口航道上，有最高值，船舶廢污水對其影響甚大，濃度次高為測站C2在A3外側，有空間上分佈意義。測站A7（林邊溪口）、A5（高屏溪河口）總濃度也非常高。
本研究總有機碳與平均粒徑間有良好的線性相關（r =0.792），然而總有機碳與各測站多環芳香烴總濃度間之相關性顯示無相關性（r =0.095），這可能係因為本研究區域範圍較大，污染源不只一個導致多環芳香烴濃度跳脫與總有機碳間關係。
主成分分析將多環芳香烴濃度高低在空間上分佈十分相似的歸為一組，影響此區的三個主成份為高分子量4~6環多環芳香烴主成份、3~4環多環芳香烴主成份及2~5環多環芳香烴主成份，共可以解釋78.89 %的變異程度。本研究並利用集群分析來加以判斷污染物分析結果的關聯性，共分三大群（Group1、Group2及Group3），依緯度高低有良好分群關係，並搭配化學指紋鑑定判斷污染物來源。
化學指紋鑑定分析此區可能污染來源，Group1（北）以石化熱裂解污染為主；Group2（中）成分最複雜，混合性來源為主；Group3（南）以石油污染為主。在多環芳香烴化合物濃度對生物的影響方面，NOAA所制訂的ERL與ERM，在物種Acp、 Phe 部分有1/3測站超過標準，Fl與Pyr物種只有測站A3超過標準，1/4測站有2個以上物種濃度超過標準。

The objective of this study is to quantify the polycyclic aromatic hydrocarbons (PAHs) of the sediments along the coast of south-western Taiwan and to investigate possible sources. The south-western coastal area is full of heavy industries. There are tens of industrial parks along with export processing zone, steel-making plant, oil refinery, shipbuilding plant, Hsin-ta pelagic fishing port, Hsin-ta thermal power plant and Kaohsiung international port. It is reasonable that the wastewater went into rivers or pipes and eventually enters coast area.
Concentrations of total polycyclic aromatic hydrocarbons (PAHs) in the sediments of south-western Taiwan were between 197.3~2498.9 (ng/g –dw) with the average of 912.0 (ng/g – dw). Among all stations sampled in this study, A3, located at the waterway of Kaohsiung, has the highest value. The wastewater ejected by ships might be the major factor. The second highest value we got is from C2, which located at the area farer from shoreline than A3. Total organic carbon (TOC) versus median particle size has linear relationship, however, total organic carbon (TOC) versus concentrations of polycyclic aromatic hydrocarbons (PAHs) showed no linear relationship. This is probably due to the wide sampling area of this study and sources of polycyclic aromatic hydrocarbons (PAHs) were not the same.
Principal component analysis shows three principal components were extracted and up to 78.79% of total variance can be explained. As indicated on rotated loadings, the three major components were characterized by 4-6 rings PAH compounds, 3-4 rings PAH compounds and 2-5 rings PAHs compounds, respectively. Results of Hierachical cluster analysis also show three major groups (Group 1, 2 and 3) can be geographically related. In addition, according to isomer ratios of PAH compounds, pollution sources of each group can be specified. Group 1, stations located northern bound, has mainly pyrogenic pollution sources, while Group2, stations located at central area of this study, has pyrogenic/petrogenic sources. For Group 3, stations located southern bound, was mainly polluted by petroleum. In regards to the sediment quality guidelines, ERL and ERM, there are one third of stations exceed ERL regarding to Acp and Phe, but only station A3 exceeds ERL regarding to F1 and Pyr.
