Popis: It was demonstrated that rhizospheric processes involving mycorrhizal fungi can influence root uptake of radiocaesium. The ability of both ectomycorrhizal and endomycorrhizal fungi to limit radiocaesium availability to their host plants was considered. The ectomycorrhizal fungi grown in forest ecosystems were suggested to immobilize between 10 and 100 % of the total 137Cs activity. Radiocaesium was found to be accumulated in mycelium and fruit bodies of ectomycorrhizal fungi by simple diffusion and facilitated transport. Ectomycorrhizal fungi was considered to be efficient indicators of cumulative biogeochemical fluxes of radiocaesium in terrestrial ecosystems and thus to be appropriate candidates for phytoremediation technique.
