Concentrations of trace elements (Mn, Fe, Co, Ni, Cu, Zn, Cd and Sr) in twenty four species of shellfishes were measured by means of inductively coupled plasma-optical emission spectroscopy (ICP-OES) and atomic absorption spectrometry (AAS). The calibration curves of ICP-OES for all elements were almost linear in the concentration range from 0.02 to 20μg/ml in standard solution, but their slopes tended to vary with the quantity of matrix elements. The results of the analysis by ICP-OES were in good agreement with those by AAS. The relative standard deviation of ICP-OES calculated for five time measurements of the same sample was less than two percent for the elements other than Co. The diversity of concentration was insignificant among the twenty four species for Co, Ni and Sr. On the other hand, Mn, Fe, Cu, Zn and Cd showed a wide difference in concentration among species as well as samples of the same species.
