[Elektronische Daten] [Jan Borovička, Jaroslava Kubrová, Jan Rohovec, Zdeněk Řanda, Colin Dunn] Concentrations of uranium, thorium and rare earth elements (REE) in 36 species of ectomycorrhizal (26 samples) and saprobic (25 samples) macrofungi from unpolluted sites with differing bedrock geochemistry were analyzed by inductively coupled plasma mass spectrometry (ICP-MS). Analytical results are supported by use of certified reference materials (BCR-670, BCR-667, NIST-1575a) and the reliability of the determination of uranium was verified by epithermal neutron activation analysis (ENAA). It appears that data recently published on these elements are erroneous, in part because of use of an inappropriate analytical method; and in part because of apparent contamination by soil particles resulting in elevated levels of thorium and REE. Macrofungi from unpolluted areas, in general, did not accumulate high levels of the investigated metals. Concentrations of uranium and thorium were generally below 30 and 125μgkg−1 (dry weight), respectively. Concentrations of REE in macrofungi did not exceed 360μgkg−1 (dry weight) and their distribution more or less followed the trend observed in post-Archean shales and loess.
