計畫中文摘要	過去十年間如美國及加拿大等相關單位提出“底泥品質準則” (SQGs, Sediment Quality Guidelines)以瞭解並保護水生生物免於化學性之污染。然我 國直至 100 年才有正式相關之底泥標準法規，但此種法規對目前台灣污染狀 況之規範仍明顯不足，所以必頇再依研究結果作為類似法規之研擬基礎。然 而不論國、內外相關底泥監測污染物均以常見之 PAHs (Polycyclic Aromatic Hydrocarbons 多環芳香族碳氫化合物)與重金屬為主，對於能鑑定污染物種 之生物指標(biomarker)而且追溯至確切污染源之環境法醫鑑定程序方式並 未建制並列入相關底泥法規，所以未來我國應該著重於此類研究。基於我國 區域特性與東部海岸特有而且僅存、寶貴之環境品質，在整個環境改變之前 必頇儘速建置相關之環境基本資料庫以規劃未來趨勢。 因此，本研究目的為建構相關污染物之篩選機制，本計畫擬延續過往之 長年監測研究，擬於東部二個最大且為代表性之二港口亦即花蓮縣花蓮漁港 與台東縣成功漁港(或稱新港)進行港口底泥採樣並檢測出成功港與花蓮港底 泥，要確切釐清污染源鑑識工作需在相對區域進行現況調查，在二個港口底 泥中均發現到生物指標化合物 BSs、terpanes、steranes，而 terpanes、steranes 因化學結構穩定，不易受風化作用影響，在油品的化學指紋鑑定上，是最為 廣泛使用的生物指標之一。依據本研究分析結果，鑑識港口底泥受油品污染 其可能主要污染來源為 R68 及 CF 潤滑油，此兩種油品因用途廣泛及價格便 宜，普遍被大眾使用，而因潤滑油生物指標有不同標準化之區別，可利用其 期標準化之差異性辨識不同污染來源，作為污染源鑑識有效依據之一。本研 究目的為建構環境法醫程序鑑定相關污染物之三類主要生物指標化合物類 (BSs, bicyclic sesquiterpanes, C14 到 C16 雙環倍半萜; terpanes, C18到 C36 萜烷; steranes, C28 到 C30 甾烷)與美國環保署公告之 16 種代表性 PAHs 污染現況以 利爾後相關港口底泥之污染物鑑定應用，期能以本研究生物指標研究結果提 供國內其它漁港進行污染源鑑識上及提供未來我國底泥於政策規劃品質項 目或進行風險評估之參考。
計畫英文摘要	In the past decades, several Sediment Quality Guidelines (SQGs) were popular adopted in the US and Canada to protect aquatic organisms. Basic concepts of “SQGs” are applying certain kinds of toxicology tests to evaluate the adverse effects to certain kinds of aquatic organisms. Before year 2011, Taiwan did not have the related sediment regulations. However, a more comprehensive laws and regulations are certainly needed for those high polluted area of Taiwan. Thus, basic researches are necessary to investigate and improve the polluted situations and being adopted into new regulations in the near future. However, PAHs (Polycyclic Aromatic Hydrocarbons) and heavy metals are the only two major listed compounds in these SQGs or sediment regulations. Environmental forensics should be take part into these regulations and especially the investigation of biomarkers among sources of pollution, polluters and polluted sites. Unlike the western coast of Taiwan, harbors that are located in the eastern part are normally less polluted environment. Thus, establishing of biomarkers’ environmental forensics technology is necessary for the future generation. Therefore, our research objectives are focus on the investigating the biomarkers and establish a proper environmental forensics technology for the two major harbors in this area. Two fishing harbors in the eastern coast were investigated and environmental forensics technologies were applied. The biomarker compounds in the related oil products and in the sediments were studied. The studied biomarker compounds are bicyclic sesquiterpanes (BSs), terpanes, steranes and the listed major 16 PAHs by the USEPA. A serious of environmental forensics procedures were conducted and the possible biomarkers in the samples were identified and quantified. The results of normalization and application of diagnostic ratios show that there are close statistic relations among studied lubricant oils and sediment samples and confirm the sources of pollution.
