Concentrations of V, Cr, Mn, Co, Cu, Zn, Se, Rb, Sr, Mo, Ag, Cd, Sb, Cs, Ba, Hg, T1 and Pb were determined in the livers, kidneys and muscles of Steller's sea eagle (Haliaeetus pelagicus) and white-tailed sea eagle (H. albicilla) from Hokkaido and golden eagle (Aquila chrysaetos) from Iwate. In general, V, Ag, Cs and Rb concentrations in the liver of raptors were found to be higher than those in other birds reported. Hg and Cd concentrations in the liver of all the raptors were low, but high Pb concentratios were detected in some raptors which remained the lead bullet in the gizzard. A significant positive correlation between Pb and Sb concentrations was observed in the liver of these raptors, indicating that Sb is a useful marker element to evaluate whether lead has been derived from bullet.
