The Black Sea which is connected to the Azov Sea in the north and to the Mediterranean in the
South, is called the largest anoxic sea in the world because 90% of its structure is anoxic. in the
Black Sea, which has undergone ecological changes for many years and nowadays, marine activities,
excessive nutrient input, increase in foreign species, wastes from the regions where agricultural
production is carried out, domestic and industrial pollution sources lead to degradations.
in this study, it was aimed to determine the degree of domestic and industrial pollution in water
and sediment by DGT (Diffusion and Gradient in Thin Films) method in the Black Sea. Five different
sampling points were selected, including Akkiraz Stream, Şabanoğlu Stream, Organized lndustrial
Zone Channel, Hıdırellez Stream and Selyeri Stream. The organic matter content, % water content and
partide size analysis were performed for these sediments. Standard analyzes such as pH,
conductivity, temperature, TOC, TN, TP were applied to the water samples. in addition, heavy metal
accumulation along the depth was observed in the sediment column with the DGT used in the
determination of the elements and compounds in the aquatic environment including natural sediments
and soils.
As a result, the organic matter content of the sediment samples was between 5.88% and 9.96%, and the
water content 14.66% and 32.79%. in the analysis of water samples, pH values were between 0.6-0.9,
dissolved oxygen values 4-12 mg / L and chemical oxygen requirement 32-192 mg / L. Analysis results
were evaluated according to the Aboveground Water Quality Regulation and international Sediment
Quality Criteria.
