Abstract

Samples were collected from an oil slick in Tuzla Bay released from two ships. The origin of the oil was identified by GC/MS and FTIR analyses. The aliphatic and aromatic group compounds were detected by GC/MS analysis. Similar FTIR spectra were obtained from the sea water and bilge water of ships. Both analysis methods support each other and they can be used for oil spillage identification. In addition to the Pr/Ph ratio, nor- Pr/Ph and nor – Pr/Ph ratios were used for the first time in the identification of oil spillage.
