The concentrations of copper, zinc, lead and cadmium in the soft parts of Mediterranean mussel Mytilus
galloprovincialis caught from the Sinop coasts of the Black Sea have been measured by an atomic absorption
spectrophotometer for monitoring metal pollution level in the coastal water seasonally in 2010. In the present study, a
statistically significant difference in the concentrations of all metals investigated was observed. The results were
compared with previous studies and discussed. It is concluded that the mussels M. galloprovincialis are suitable
biomonitors to assess changes in metal pollution in this coastal area of the Black Sea.
