Abstract
The spatial distribution pattern and transportation of heavy metals in sediments (up to 10 cm) were studied along Sinop
peninsula of the southern Black Sea. The influences of anthropogenic metals pollution in surface sediments of Sinop Peninsula in the
Black Sea were assayed by using I
geo
.
Metal contents were significantly correlated each other. Heavy metal concentrations showed a
significant relationship with Fe content, while most heavy metals were not enriched. The levels of most metals at all stations were
lower than the contents indicated by the sediment quality.

Introduction
Coastal ecosystems are amongst the veriest prolific and vigorous ecosystems on marine environment. The
development in seaside regions has rised the anthropogenic activities on the coastal ecosystems, with the inclusion
of the disruption of many water system owing to increased supplies of land-based nutrients and other chemicals
such as metals. Pollutants sustein to be entered into marine coastal ecosystem thanks to rivers, runoff and
land-based hot spots, and so, heavy metal contamination is one of the important issues in the Black Sea. When
heavy metals get into the sea environment eventually will settle into sediments withal organic matter (Bat and
Raffaelli, 1998), and may influence the health of the ecosystem.These sediment-bonded metals may also be let
into the water column again under variable conditions. Thus, the metal contents in sediment surface can emit the
pollution level of the coastal water and geochemical behavior of the metals. In recent years, increasing quantities
of heavy metals from rivers and anthropogenic activities have been discharged into the Black Sea, resulting in the
continual deterioration of the water quality (Bat and Baki, 2014).
The Black Sea is the largest naturally anoxic water in the world (Jessen et al., 2017), with many rivers flowing
into it. In the north-western side Dnieper, Southern Buh, Dniester, and Danube rivers are the main tributaries. The
rivers running into the northern side of the Black Sea transport excessive silt and form deltas, sandbars, and
lagoons throughout the usually low and sandy northern coast. In the southern side Sakarya, Kizilirmak and
Yesilirmak are the biggest rivers. The southern coast is steep and rocky. The Black Sea has two layers of water of
different densities. The very salty depth layer which originates in inflowing Mediterranean waters has very slow
movement and covers hydrogen sulfide; it has no eukaryotic vita. The suface layer, much lesser saline flows in a
counterclockwise direction around the sea.
The Black Sea coasts are impacted by anthropogenic pressures especially fast industrialization and development
in the coastal regions resulting in pollution of marine sediments by persistent chemicals such as heavy metals (Bat
and Özkan, 2015). Risk assessment of sediments was determined by these heavy metals, it is a highly effective
analytical tool. Land based pollution combined with population growth, originate increasing pressures into the
coastal environment of the Black Sea (Bakan and Büyükgüngör, 2000; Bat et al., 2009; Bat, 2014; Büyükgüngör
et al., 2014), involving the degradation of coastal ecosystem.
