The black sea is an almost enclosed sea that opens only to the Mediterranean with the Çanakkale and the Istanbul Strait. There are many discharges affecting the pollution of coastal areas such as river, industrial, agricultural and domestic wastewater. It has been converted from an oligotrophic (less than 100 grams of organic carbon per meters squared per year [g C/m2/yr]) system prior to the 1970s (the pre-eutrophication phase) to a eutrophic (300 to 500 g C/m2/yr) system over the subsequent two decades (the eutrophication phase). There are many factors in reaching this level. The pollutant inputs of nutrients and alien species, overfishing and climate change are among the factors that affect the physical structure. In addition, chemical and microbiological pollutants, organic pollutants, heavy metals, petroleum pollution has caused a significant deterioration of the Black Sea in terms of aesthetic, recreational activities and water quality.

In order to determine the pollutants formed in the Black Sea,% water content, organic matter, total organic carbon (TOC), total nitrogen and phosphorus, chlorophyll-a were analyzed in sediment samples taken from five different sample points discharging to Black Sea coast of Turkey.

These analyzes in which the results are determined, it is aimed to determine the quality of the sediment and the trophic state of the mid-Black Sea coast of Turkey, according to the results of the analysis of sediment samples taken from the sampling points Dereköy, Canik, Terme, Koşuköy and Fenerköy. Comparing with the water sample analyzes, the land based pollution load of certain pollutants are going to be evaluated at sediment samples in order to determine the near past changes at the mid-Black Sea coast of Turkey.

Keywords: Black Sea, Land based pollution, sediment quality, trophic state.
