摘要: Concentrations of 18 trace elements (V, Cr, Mn, Co, Cu, Zn, Se, Rb, Sr, Zr, Mo, Ag, Cd, Sb, Cs, Hg, Tl and Pb) were determined in liver, kidney, muscle hair Baikal seals, Caspian seals northern fur seals. All the three species showed highest concentrations V, Se Ag Co Cs among soft tissues examined. The burdens Rb observed muscle, Mo Sb Pb all species. non-essential elements, significant positive correlations kidney whereas correlation coefficients for essential Zn between generally low species, suggesting that homeostasis controls but not these animals. Significant age-dependent increase was found liver Hg Hair with levels Furthermore, regression analysis using data present study literature hair, various pinnipeds. These results indicate possibility samples monitoring
