Oil accumulation in mussels was investigated after the Nassia oil tanker accident on the Istanbul Strait by applying UVF and GC/MS analysis methods. Pristane and phytane ratio was used to distinguish the sources of pollution. Amounts of oil varied from 5 to 250 µg/g in three surveys. The analysis results revealed that contamination originated from the oil spilts from the tanker involved in the accident.
