Increasing marine traffic, over 55,000 ships visit per year, through the Turkish Straits System and the Sea of Marmara, produces a yearly average of 12 illegal oil discharges. This paper documents the comparison of chemical fingerprints of spilled oil with suspected sources of oils for identifying the source of illegal pollution in Turkey's seas. Fingerprinting is initiated by comparison of the synchronous fluorescence spectra (Δ=20 or 15 nm) of fugitive and suspected source oils. Potential matches of the spectra/chromatogram are confirmed or rejected by subsequent comparison of Fourier transform infrared spectrometry (FTIR), high-pressure liquid chromatography (HPLC) and gas chromatography with a flame ionisation detector (GC-FID) analysis results. In this study, 39 clean sea waters, 41 polluted sea waters and 111 suspected samples were analysed. According to the comparison of the suspected source sample and polluted sea water sample spectra by using spectrofluorometric analysis, 76 suspected source samples were categorised as non-match whilst 35 suspected samples were classified as match or probable match. Then, match and probable match samples were analysed by using further selected chromatographic methods. Finally, 28 suspected source samples were confirmed as a match, enabling legal proceedings to be initiated.
每年有超过55000艘船只通过土耳其海峡系统和马尔马拉海，海上交通日益繁忙，每年平均发生12起非法排油事件。本文记录了溢油化学指纹与可疑油源的比较，以确定土耳其海域非法污染的来源。指纹识别首先通过比较逃逸油和可疑源油的同步荧光光谱（Δ=20或15纳米）来启动。光谱/色谱图的潜在匹配通过随后比较傅里叶变换红外光谱（FTIR）、高压液相色谱（HPLC）和带有火焰离子化检测器的气相色谱（GC-FID）分析结果来确认或排除。在本研究中，分析了39个清洁海水样本、41个污染海水样本和111个可疑样本。根据荧光光谱分析对可疑源样本和污染海水样本光谱的比较，76个可疑源样本被归类为不匹配，而35个可疑样本被归类为匹配或可能匹配。然后，使用进一步选择的色谱方法对匹配和可能匹配的样本进行分析。最后，28个可疑源样本被确认为匹配，从而能够启动法律程序。
