In this work the total Cd, Co, Cr, Ni, Zn, Fe, Mn, Pb and Cu contents is measured in shallow sediments from the Bosphorus, Gökova, Marmara and Black Sea stations are measured. Generally Cd and Pb concentrations are lower than the detection limit (0.01µg/L)of the method in Yesilirmak, Kizilirmak and Sakarya samples whereas Co, Cr, Ni, Zn, Fe and Mn contents are higher than the shale average. Cd is rather high in Bosphorus and Marmara sediments and Cd and Mn contents are rather high in Gökova sediments compared with shale average.
