| Summary: | The concentration of some heavy metals in sediment from the Sinop coasts of the Black Sea were measured to
monitor metal pollution in 2013. The distribution of the heavy metals in sediments of the Black Sea shows a variable
pattern. The objectives of the present study were to elucidate the distribution of heavy metals such as Cu, Pb, Zn,
Ni, Mn, Fe, As, Cd, Cr, Hg and Co in sediment from Sinop coast of the Black Sea. In order to determine. The quality
of sediment in the Black Sea, pollution levels of the metals were evaluated using the enrichment factor technique
(EF). The lowest EF values were between 0-5 in Cu, Fe, Zn, Ni, Cd, Pb, Mn and Co. These values did not have
statistically significant differences. As, Cr and Hg concentrations were estimated relatively higher enrichment
values than other the metals. The results indicated that contamination of surface sediments in Sinop Coast is
dominated by As (10.2-7.4 mg.kg^-1), Cr (67-374 mg.kg^-1) and Hg (0.07-0.03 mg.kg^-1) and to a lesser extent Cu (7.24-
5.09 mg.kg^-1), Fe (1.76-1.12%), Zn (19.3-13.8 mg.kg^-1), Ni (16.2-12.5 mg.kg^-1), Cd (0.06-0.04 mg.kg^-1), Pb (7.12-6.32
mg.kg^-1), Mn (470-227 mg.kg^-1), Co (9.5-5.9 mg.kg^-1). Also, the requirement of age determination is of great
importance to assess the extent of the anthropogenic contribution in pollution |
