建立柴油污染同位素比値溯源技術

中文摘要 國內自加油站開放民營後,油品市場自由競爭激烈,加油站經營主體或使用油品供應源更換頻繁,往往造成油品洩漏污染事件發生時,責任歸屬難以釐清,產生許多爭議。因此如何鑑識油污染來源及釐清責任問題是當前急需解決的議題。目前油品鑑識技術主要以生物指標分析技術(Biomarker),但近年來國外仍發展許多新的分析技術。其中同位素比値法因同位素穩定性高且經研究指出不同之油源可能具其特徵性,故本計畫將針對此技術應用於柴油溯源進行探討。 參考文獻方法建立柴油中直鏈正烷類的碳及氫穩定同位素比值分析技術,完成中油與台塑油品合計24個市售柴油樣品GC/IRMS分析與資料整理。將24個市售柴油樣品的油品進行PCA群聚分析,結果顯示氫同位素比値分析法可將中油及台塑分為兩大群,但中油具有南北兩家煉油廠,不同煉油廠的柴油樣品其特徵相似,無明顯差別。而碳同位素比値分析法則無法有效區分中油及台塑兩大供應源。將24個市售柴油樣品進行生物指標分析法並將數據與同位素比値對照後,兩者皆可將中油及台塑柴油樣品區分,而生物指標分析法中,中油南北縣市之柴油樣品亦有分群,同位素比値分析法則無此現象。但本計畫顯示中油及台塑油品之氫同位素比値具有鑑別性。

Compound specific isotope analysis of diesel fuels in a forensic investigation

英文摘要 Based on the results accumulated in this project, we have achieved our goals to establish the protocols of the carbon and hydrogen stable isotope ratio technology for the oil spill identification. 24 commercialized diesel samples collected from the gas stations of both CPC Co., Taiwan, and Formosa Petroleum Corporation, were acquired for GC/IRMS analysis and subsequent data process. The information has been imported for the carbon and hydrogen stable isotope ratio database of the commercialized diesels. To gather 24 samples collected until now, we have further carried out the study of their principal component analysis-diagnostics ratios (PCA-DRs) and been evaluating the technology if it is valid for source identification of the commercialized diesel oils. Besides the carbon and hydrogen stable isotope ratio technology, 24 commercialized diesel samples were acquired for GC/MS analysis to obtain chemical fingerprinting database. We have further carried out the study of their principal component analysis-diagnostics ratios (PCA-DRs) and been verifying the compound specific isotope ratio analysis technology of diesel is indeed valid for source identification of the commercialized diesel oils.
