The Dardanelles (Canakkale Strait) is a water transport channel connecting between the Black Sea (via the Marmara Sea) and the Mediterranean (via the Aegean Sea). The average depth of the Strait is approximately 60 m; the deepest point reaches more than 106 in. The interaction of coastal and submarine morphology with the hydrodynamic regimes exerts a control on coastal dynamic processes depends on NE/SW stretch is flowed by deep and surface water. Mn, Fe, Ni, Cu, Zn, Pb and Al concentrations have been measured from surface sediments collected around 7city coastal locations around. Sediments analysis was conducted on sediment samples and Atomic Absorption Spectrophotometry was used in the analyses of sediment heavy metal concentrations. Elevated concentrations of Mn (927-355.90 ppm), Fe (1.40-2.46 ppm), Ni (30.10-50.90 ppm) and Cu (8.70-23.30 ppm), Zn (34.5076.20ppm), Pb (10.60-21.20 ppm), Al (3.20-4.50 ppm) are present in the tailings. Trace element concentrations in shallow marine sediments of the Dardanelles district of some city are affected by submarine disposal of natural costal mine tailings and unregulated dumping of tailings and wastewater from small-scale. The results showed that metals concentrations in sediments can be considered near the background levels. Metal concentrations were probably caused by decreased rates of marine water flow erosion.

Abstract


The Dardanelles (Canakkale Strait) is a water transport channel connecting between the Black Sea (via the Marmara Sea) and the Mediterranean (via the Aegean Sea). The average depth of the Strait is approximately 60 m; the deepest point reaches more than 106 in. The interaction of coastal and submarine morphology with the hydrodynamic regimes exerts a control on coastal dynamic processes depends on NE/SW stretch is flowed by deep and surface water. Mn, Fe, Ni, Cu, Zn, Pb and Al concentrations have been measured from surface sediments collected around 7city coastal locations around. Sediments analysis was conducted on sediment samples and Atomic Absorption Spectrophotometry was used in the analyses of sediment heavy metal concentrations. Elevated concentrations of Mn (927-355.90 ppm), Fe (1.40-2.46 ppm), Ni (30.10-50.90 ppm) and Cu (8.70-23.30 ppm), Zn (34.5076.20ppm), Pb (10.60-21.20 ppm), Al (3.20-4.50 ppm) are present in the tailings. Trace element concentrations in shallow marine sediments of the Dardanelles district of some city are affected by submarine disposal of natural costal mine tailings and unregulated dumping of tailings and wastewater from small-scale. The results showed that metals concentrations in sediments can be considered near the background levels. Metal concentrations were probably caused by decreased rates of marine water flow erosion.
