Marine organic pollutants of the Eastern Aegean: aliphatic and polycyclic aromatic hydrocarbons in Candarli Gulf surficial sediments.
Aliphatics and PAHs were determined in sediments from the Candarli Gulf in 2009. Aliphatics ranged from 3.88 to 24.7 μg g(-1) while aromatics varied between <4.15 and 405 ng g(-1) (dw). PAHs ranged from a relatively low to a moderate PAHs pollution compared to other urbanized coastal areas worldwide. 3-ring PAHs were most abundant in the sampling area. Both pyrolytic and petrogenic PAHs were present in most samples, although petroleum derived PAHs were dominant at the stations situated near the refinery and petrochemical, metal industry and pyrolytic sources were mainly prevalent in the estuary of Bakircay River. The ratio of UCM to n-alkanes and CPI values in station 6 indicate that the main contribution to petroleum hydrocarbon contamination is via oil and its products. PAH levels at all sites were below the ERL and ERM except fluorene. The results indicated that the sediments should have no potential biological impact except stations 6 and 14.
