Total and methyl-mercury content in bivalves, myilus galloprovincialis Lamarck and Ostrea eulis Linnaeus: Relationship of biochemical composition and body size

The relationship between total and methyl-mercury content and body mass in mussels and oyters collected in Limski kanal, northern Adriatic Sea, in the winter and spring seasons were investigated. the results indicate that oysters are more effective bioaccumulators than mussels before the spawning season. In both species, total and methyl-mercury content increased in correlation with dry weight. greater mthyl-mercury changes were measured in the larger mussels during the reproductive period, but in oysters no such effect was noted. In both species the mercury content was influenced by the events of reproductive cycles.
