Trace elements in organs and tissues of striped dolphins(Stenella coeruleoalba) from the Mediterranean sea(Southern Italy)

摘要

The distribution of metals (Cd, Cu, Zn, Fe, Cr, Pb and Sn) were investigated in various tissues and organs obtained from striped dolphins(Stenella coeruleoalba) stranded along the Apulian coasts(Southern Italy) during April-July 1991. Metals were determined by atomic absorption spectrophotometry. Metal concentrations were generally high in the liver, and low in brain and melon. Some metals showed organ-specific accumulations: copper, tin and zinc exhibited high concentrations in liver, the highest cadmium concentration was observed in kidney.
