In this study the 279 samples of sea water, 6 mussel, 1 alg and GOTIA fuel oil were analysed by UVF and 287 samples by GC/MS and 200 samples by fingerprinting technique. The oil contamination was spread out at Istinye, northern part of Bosphorus at Golden Horn and at Yenikapi (near south end of Bosphorus). The maximum oil levels found after the accident were 813.5 mg/L in Bosphorus is 7.3 mg/L in Golden Horn and 27.4 mg/L at Yenikapi.
