ABSTRACT
As is well known, a powerful earthquake along the North Anatolian Fault struck the eastern part of the Marmara region on August 17, 1999. Izmit Bay, which is known as one of the most polluted sites of Turkey, was also affected by the quake and the subsequent refinery fire. The measurements performed just before and after the earthquake showed that T-PAH levels increased significantly after the event [Okay OS, Tolun L, Telli-Karakoç F, Tüfekçi V, Tüfekçi H, Morkoç E. Izmit Bay (Turkey) ecosystem after Marmara earthquake and subsequent refinery fire the long-term data. Marine Pollution Bulletin 2001;42361-9]. In the framework of ecotoxicological studies, the Bay ecosystem was continuously monitored for T-PAH levels in seawater, sediments and mussels (Mytilus galloprovincialis) to find out whether change occurred during the 2-year period following the earthquake. For that purpose, after the earthquake, the samples were collected six times between the period of September 1999 and March 2001 at coastal stations of the Bay situated away from the mouth of main discharges. The responses of the mussels were also measured by means of the lysosomal stability of the blood cells and feeding rate biomarker techniques at two different sites of the bay. Although the T-PAH levels in all matrices generally showed a decreasing trend, they were found to be still high especially at stations near the refinery. Both biomarker results showed that the health status of the mussels is very poor in the Bay ecosystem, based on the results obtained from the two sites monitored.
