    Abstract:
    Polycyclic aromatic and aliphatic hydrocarbons were analyzed in red mullet and annular sea bream from the Izmir Bay. These fishes were selected because of their multitude, wide distribution and common use in the Turkish diet; they were sampled and analyzed in 2000-2001 and 2004-2005 periods at five locations by trawling. Red mullet showed higher PAHs and aliphatics than annular sea bream. PAH levels for red mullet and annular sea bream ranged from 202 to 556 and 78.7 to 415; aliphatics ranged from 834 to 2,420 and 436 to 1,724 ng/g dw, respectively. Molecular ratios showed pyrolitic inputs for PAHs, biogenic and anthropogenic inputs for aliphatics. The carcinogenic PAH, benzo(a)pyrene, was detected in most fish samples in levels ranged between 22.2 and 64.1 ng/g dw. The average PAH contamination level was within the "moderate" category in fish from Izmir Bay. Results indicate the needing of a systematic monitoring program in order to provide accurately assessment and management of risks for the regional population.
