Abstract
Estimation of level contamination of marine ecosystems with heavy metals is important task in the field of MSFD. Total zooplankton samples were collected using a standard zooplankton net (mesh size = 112 µm, mouth diameter = 50 cm) from Sinop coast of the Black Sea, Turkey in 2011 and 2012. Concentrations of Al, As, Cu, Zn, Hg, Fe, Cd and Pb were determined in the total zooplankton samples. The average concentration of heavy metals followed order: Fe > Al > Zn > Pb > Cu > As > Cd > Hg. Of all the heavy metals estimated Hg was below the detection limit in all the samples. Fe was the most common heavy metal in total zooplankton samples present in all, Al was the other heavy metal commonly present in the samples. Pb showed high value (210 mg·kg-1) in total zooplankton. Similar to Pb, a high average concentration of As (40 mg·kg-1) was observed in total zooplankton. Cd was 1.1 mg·kg-1.
