The concentrations of 16 polycyclic aromatic hydrocarbons (PAHs) in surface sediments collected from 44 sites of the Ä°kizcetepeler Dam Lake, in BalÄ±kesir province of Northwestern Turkey are determined. The soxhlet extraction procedures had been optimised and validated by using gas chromatography-Mass detector (GC_Mass). Recovery was in between 56-124%. Relative standard deviation was less than 1% and limit of detection changed from 0.0010 to 0.028 µg/g. The accuracy of the method was verified by analyzing National Institute of Standards and Technology, Standard Reference Material 1597 (NIST SRM 1597). The selectivity, accuracy and precision were quite adequate for the determination of PAHs in sediment samples. The sum PAH concentrations was 0.19 ± 0.07 mg/kg. The Factor Analysis (FA) and diagnostic analysis results indicated that pyrogenic and petrogenic sources are the important sources of PAHs. Further analysis showed that contributions of Factor 1 (mixed) and Factor 2 (pyrogenic) are 37.9% and 26.9% respectively. Factor 3 (explains 15.4 of the total variance), represents petrogenic (spills of oil products) source.
