摘要：
Samples of wild growing ectomycorrhizal and terrestrial saprobic macrofungi (mushrooms) were collected from unpolluted areas and analyzed for their iron, cobalt, zinc and selenium content. Trace elements were determined using long-term instrumental neutron activation analysis. In total, 217 samples, including 87 species of ectomycorrhizal fungi and 43 species of terrestrial saprobes, were examined. Distribution of trace element contents in ectomycorrhizal and saprobic macrofungi was investigated; results are thoroughly compared with previously published data. Doubtful literature data and ability of macrofungi to accumulate/concentrate investigated elements are discussed. Hygrophoropsis aurantiaca was found to concentrate Fe and Russula atropurpurea was confirmed as an effective Zn-accumulating species. Distribution of Se in ectomycorrhizal species was obviously different from that in saprobic species; selenium contents were higher in saprobic species (mostly above 2 ppm).
