Uptake, distribution, and velocity of organically complexed plutonium in corn (Zea mays)

Potential of Vetiveria zizanoides L. Nash for phytoremediation of plutonium (239Pu): Chelate assisted uptake and translocation

“…Our results are an agreement with Thompson et al (2012) who reported similar findings with corn plants exposed to 239 Pu, which showed 98% of 239 Pu retained in the roots and remaining amount of Pu entered in the shoots. Adriano et al (2000) also reported accumulation of Pu in various root vegetables like carrot, red beet, and turnips from contaminated sites.…”

Differences in Copper Absorption and Accumulation between Copper-Exclusion and Copper-Enrichment Plants: A Comparison of Structure and Physiological Responses

“…Plants have developed complex mechanisms for transporting mineral nutrients to optimise their growth and reproductive success over a range of environmental conditions [ 3 ]. In general, metal ions are removed from the soil via a low-resistance apoplastic or symplastic pathway and transported to other parts of the plant through the xylem[ 4 , 5 ]. At the whole-plant level, long-distance transport is essential for the distribution of a variety of mineral nutrients [ 6 ].…”

The Rise of Magnetically Recyclable Nanocatalysts

“…This was attributed to the Pu IV ‐ and Fe III ‐DFOB complexes having similar shapes and charge‐to‐ionic‐radii ratios. Plutonium complexed with DFOB was observed to have a much higher uptake rate in corn plants compared with uncomplexed Pu 23. This was attributed to similarities of Pu to Fe as well as to the overall stability of the Pu‐DFOB complex.…”

“…Whereas previous studies have provided insight into the importance of soluble organic matter and siderophore complexation on Pu mobility and, in particular, the behavior of Pu‐DFOB complexes,23,16,22 little work has been done to specifically determine the structure of Pu‐DFOB complexes in environmentally relevant solution conditions. An understanding of the structure and morphology of such complexes is critical to explaining their functional behavior in the environment.…”
