Curium in plants

Published information on the occurrence and distribution of curium in plants is surveyed. Results from field studies are limited and the majority of the relevant data derive from glasshouse experiments in which (nominally) root uptake was the only means of entry of curium into the plant. Often, experiments designed to investigate the effect of a particular factor on the uptake of curium by plants (e.g. a soil chemical property, species of plant) have, due to analytical difficulties, yielded inconclusive results. Occurrence in plants; soil-plant relationships; species-dependence of its concentration ratios; root uptake; and the distribution within plants are considered. (Auth./G.J.P.)
