The concentrations of Cd, Hg and Pb in the whole parts of the worm Nereis diversicolor collected from the Turkish Black Sea coast have been measured by ICP-MS (Inductively Coupled Plasma -Mass Spectrometer) for monitoring metal pollution in 2015. Seasonal differences in the amounts of Cd, Hg and Pb in the sediment were not significant. The amounts of Pb were found to be higher in sediment than those of N. diversicolor. On the other hand Cd and Hg amounts in the worms were higher than the sediment. However, there were significant differences in toxic metal levels between sizes of N. diversicolor. Larger specimen accumulated less toxic metal. Cd had the highest CF mean followed by Hg and Pb showed the lowest CF value. It is concluded that the worm N. diversicolor are suitable biomonitors to assess changes in metal pollution in this coastal area of the Black Sea.
