Sažetak
Mediterranean Blue Mussel (Mytilus galloprovincialis) has been widely used to monitor accumulation of metals, especially bivalent metals, and lipophilic organic compounds. They are primary accumulated in the soft tissue of mussels ; therefore, the most of investigations are focused on bioaccumulation of metals in flesh. Some results suggest that M. galloprovincialis could be efficient indicator for lead, zinc and cadmium. The metal content in shell was rarely studied, despite the fact that could provide a great amount of useful information in biomineralization process. It is already known that the shell of Mytilus species is consisted of rhombohedra calcite in the outer layer, and orthorhombic aragonite in the inner layer. Different mineralogical structure of shell layers implies incorporation of metals with different ionic radius into calcite or aragonite layer. For example, Fe, Mn, Cu and Zn ion with smaller radius than Ca can easily be incorporated into calcite structure, and Cd, Ba and Pb ion with greater radius can be incorporated into aragonite structure. Metal content in the shell is influenced by environmental conditions ; metals are accumulated through biomineralization process, precipitation or adsorption from water. Majority of the data published through Mediterranean Mussel Watch Project described impact of metals on mussels’ soft tissue and there are only a minor number of studies concerning shell analysis. Mussel samples used in our study were collected at several locations along the east coast of the Adriatic Sea, especially near the hot-spots of possible anthropogenic impact on the marine environment and analysed by inductively coupled plasma atomic emission spectrometry (ICP-AES). It is shown that ICP-AES analysis of shell provides reliable data which could be used in determination of current environmental status and also in the estimation of possible anthropogenic influences on marine ecosystem
