Özet
This study aims to evaluate the relationship between organic and inorganic substances in the recently observed pollution in the Sea of Marmara. The heavy metal analysis results of the sediments taken from the sea were interpreted by quality assessment methods. Polluted spots are the sea areas adjacent to the Gemlik and Bandirma locations and the areas where wastewater is discharged into the sea. Organic matter and elemental analyses of marine waters taken from streams (Nilufer cayi and Gonen cayi) which are thought to carry pollution loads into the sea and from the points where they are poured into the sea revealed that their concentrations are very high. Analysis results of drilling and gravity core samples taken from the study area show that organic materials accumulate more in the sediments of the current period than in the old periods. In the current period, the primary sources of pollution in the Sea of Marmara are domestic and industrial wastewater discharged directly or indirectly into the sea. Secondary sources are ship traffic and agricultural activities. In addition, we observed that the main causes of eutrophication and mucilage, which are observed frequently in the Marmara Sea, are organic matter and heavy metal pollution. Morphological changes are frequently observed in foraminifera members located in locations where heavy metals are concentrated.
