| Summary: | 碩士 === 國立聯合大學 === 環境與安全衛生工程學系碩士班 === 97 === Petroleum is a complex mixture of a variety of organic compounds and primarily contains alkanes, aromatic hydrocarbon compounds, and smaller amounts of nitrogen, sulfur, oxygen, etc. Over the years chemical fingerprinting techniques have been developed for the purpose of assessment of the oil contaminants. Also, once oil spilled, it will undergo the so called weathering process that will change oil compositions and make it more difficult to characterize and determine the source. As biomarkers like steranes and terpanes are source specific and are resistant to the weathering effects and not easily be biodegraded. Therefore biomarkers analytical technologies are widely used in oil spill identification. It is the most effective method for identification of the source by comparison of the diagnostic ratios of biomarker compounds and related chemical fingerprinting. This study established the oil sample pre-treatment process and the operating conditions of GC/MS and GC/FID instrumental analysis. Weathering primarily the vaporization process was conducted both on the single oil pollutant and the mixture of two oil pollutants with different ratios. The effects and phenomena of the mixing and weathering processed are observed and assessed. The various diagnostic ratios of the target biomarker compounds are calculated and compared.
