During the last decades, the Black Sea has experienced severe environmental degradation in terms of
its biodiversity, habitats, recreational value and water quality. The environmental crisis is a
direct consequence of the increasing human activities along the sea shores since the Black Sea is
a regional sea and it is of great economic importance for the countries situated around its
coasts. The Black Sea is experiencing severe environmental problems such as eutrophication, chemical,
oil and bacterial pollution, as well as biological pollution through the accidental introduction of
The main aim of this study was to investigate the marine water quality at the mid-Black Sea coast
(Sinop, Samsun, Ordu) of Turkey. In addition, the research was carried out in order to investigate
the seasonal and spatial variations in surface water quality at the mid-Black Sea coast of Turkey.
Marine water samples were collected from 13 stations at 3 miles and 20 miles distance from the
coast during the winter, spring, autumn and summer seasons between 2013 and 2014.
In this study, water quality data of several physical and chemical parameters for samples of shore
stations along the mid-Black sea coast of Turkey were analyzed. At each sampling station, water
temperature, pH, temperature, dissolved oxygen (DO), redox potential (Eh), total dissolved solids
(TDS), electrical conductivity (EC) and salinity were measured in the field using a field
multiprobe (Consort C535). Phenol (Ph), methylene blue active substances (MBAS) and ammonium
(NH4+-N) concentrations of the samples were measured with proper analytical kits using a PG-T70
According to the results of the measurements, the mid-black Sea part of Turkey is evaluated in terms
of marine water general quality criteria given in the water pollution control regulations of
Turkey, it is seen that phenol concentration exceeds 0.001 mg/L limit value.
