Mersin Bay is under the effects of pollution, resulted from urbanization, agriculture and industrial processes. Trace metals is an important source of this pollution. The aim of this study is to determine the levels of concentrations of Cd, Pb and Cr in two Patellla species and seawater collected from Mersin Bay. Sampling of P. caerulea, P. rustica and surface water was carried out in Kazanli{dotless}, Karaduvar, Mersin Port and Mezitli region which was mainly affected from pollution. From each species, 25 individuals were collected from each sampling point. P. rustica was not observed in Kazanli{dotless} and Mersin Port. The shell indices of P. caerulea and P. rustica was calculated as mean 1.91 and 2.36, respectively. Cr concentrations in P. caerulea collected from Kazanli{dotless} and Karaduvar was higher than other sampling points. Whilst the Mersin Port was characterized by higher Cd concantrations. Kazanli{dotless} was characterized by high levels of Pb concentrations. Higher trace metal concentrations were found in P. rustica collected from Karaduvar compared to Mezitli although there was no significant difference between these sampling points. When the trace metal concentration of two species were compared, it was observed that P. rustica contaminated higher amount of Cd and Cr concentrations.
