Uranium accumulation in the lichen Cladonia rangiferina. Part I. Uptake of cationic, neutral, and anionic forms of the uranyl ion

Evidence from published work is first reviewed to show that cationic, neutral, and anionic complexes of the uranyl ion are available to plants growing in uranium-enriched environments. The results of a study on the uptake of uranyl ions by the lichen Cladonia rangiferina L. Wigg. are then presented. Uptake was examined from three different uranyl solutions each predominantly containing a single species: namely, the cation [Formula: see text] …
