Abstract: Total 125 surface sediment samples were taken from NE Aegean Sea (82 samples), Çanakkale (Dardanelles)Strait (23 samples), Junction of the Marmara Sea with the Dardanelles Strait (DSMJ) (20 samples). Grain size andheavy metals (Fe, Mn, Zn, Ni, Pb, Cu, Co, Cr) the samples were determined by standard methods.N E Aegean Sea, Çanakkale (Dardanelles) Strait, DSMJ surface samples mean mud percentage were found 34.3%,74.1%, 79.9% by mass. The highest mean metal value was calculated in the DSMJ sediment. In the Çanakkale(Dardanelles) Strait sediments some heavy metals concentrations reach same data with DSMJ. Outside Pb all heavymetals show positive correlation with mud in the DSMJ. Heavy metals-mud correlation show positive correlation inthe Dardanelles Strait. But, other parameters for example antropogenic and land-particulate effect to deposition of heavv metal in the DS sediment. In the NE Aegean Sea sediment Ni, Cr, Zn, show high correlation cofficient with mudaccording to Pb, Mn, Fe, Co, Cu. General distribution of Pb, Mn, Co, and Fe decent on different parameters besidesmud size. Cu, Cr, Zn, Ni have high correlation with mud in the studying areas.
