Title: Trace elements and their significance in the postnatal development of seasonal generations of the bank vole
Abstract: Examination was made of concentrations of 10 trace elements (Fe, Zn, Co, Se, Sb, Eu, Cr, Hg, Sc and Ce) in the liver, kidneys and heart of the bank vole, Clethrionomys glareolus (Schreber, 1780), in indyviduals of the spring and autumn generations, during the postnatal development of these animals (1-60 days). Two types of elements were distinguished, differing in respect of contents in the dry mass of organs from voles of the generations compared, but the same age.
