Abstract

Relationships between the concentrations of 13 trace elements and δN were identified to investigate the trophic-level-dependent accumulation of elements in biota from Suruga Bay, Japan. The results showed biomagnification for Hg, As and Se (very weak for As and Se), biodilution for Cd, Cu, Mn, Ni, Pb, Sb and Zn, and nontrophic relationships for Co, Cs and Mo. It is likely that the biomagnification of Hg does not differ significantly with the location, whereas some trace elements, such as As, Se and Zn, show a characteristic trophic transfer in each location, depending on the food web structure and environmental factors.
