About the report
A review of the literature on U uptake by plants has shown there to be a paucity of data, especially for hydrophytes. In many instances, data are comprised by a lack of quality assurance protocols to determine the level of contamination of shoots and roots by soil and/or dust. In addition, there is poor understanding of U absorption by plants, response, translocation and storage. Where U is labile and present in relatively high concentrations in a substrate, plants are capable of translocating U to the shoot but with higher concentrations generally found in the root.
