Abstract:

This work presents aspects regarding some heavy metals (Cd, Pb, Cu and Zn) concentration in shells of different mollusks (Mytilus galloprovincialis, Rapana thomasiana, Mya arenaria, Scapharca) collected from the Romanian Black Sea Coast (Mamaia zone), in August 2007. The heavy metals were analyzed using atomic absorption spectrometry. We used atomic absorption spectrometry to establish the concentration of heavy metals: Cd (? = 228.8 nm), Cu (? = 324.7 nm), Zn (? = 213.9 nm) and Pb (? = 217 nm). We observed a high concentration of Zn in the Mytilus [22.99 ?g•g-1] and Rapana [16.82 ?g•g-1] samples comparing to the other samples. In the Rapana samples we have detected the lower concentration in Cu [5.88 ?g•g-1]. In the shells samples of Rapana we have detected the highest concentration in Cd [0.94 ?g•g-1]. The shells of Scapharca have presented the lower concentration in Pb [3.11 ?g•g-1]. In Mya arenaria samples it has been detected the highest concentration in Pb [9.93 ?g•g-1].
