Abstract

The concentration of heavy metals (Zn, Cu, Ni, Cr, Cd, and Hg) in sea water was determined along the Turkish Straits (Dardanelles and Bosphorus) and in the Marmara Sea. The concentrations are ranging between 13.26-144.9 ng/L for Zn, 0.23-0.77 jig/L for Cu, 0.41- 5.42 ng/L for Ni, 0.26-2.56 ng/L for Cr, 0.67-12.67 ng/L for Cd and 2.0-5.3 ng/L for Hg. By utilizing the average metal concentrations and annual average water fluxes between Aegean-Marmara-Black Seas the metal fluxes in the region were determined. 1. INTRODUCTION Turkish Straits system are shown in Figure 1. The hydrography and the water circulation of the system is extensively studied and published by Unluata et al.and Be§iktepe et al. Ozsoy^ and can be summarized as follows: The Marmara Sea is a small inter-continental basin. It connected to Aegean and Medi
