Özet

In this study, organochlorine and toxic metal (Pb, Cd and Cr) analyses have been done in the surface sediments. Sediment samples have been collected from 7 parts of the Marmara Sea and the coast of Istanbul during 2009. Total Pb, Cd and Cr contents vary between 32 mu g g(-1) and 122 mu g g(-1); 0.19 mu g g(-1) and 1.16 mu g g(-1); 62 mu g g(-1) and 372 mu g g(-1), respectively. EF values of Pb and Cr are higher than 1.5 in all the stations. EF value of Cd is considerably high at Station MY1 (Tuzla Port). Total organochlorine residue contents range between 4.33 ng g(-1) and 22.2 ng g(-1) in the surface sediments. (C) 2012 Elsevier Ltd. All rights reserved.
