Elucidating the Role of Dissolution in CeO2 Nanoparticle Plant Uptake by Smart Radiolabeling

Elucidating the Role of Dissolution in CeO2 Nanoparticle Plant Uptake by Smart Radiolabeling
Heike Hildebrand, Stefan Schymura, Thomas Fricke, Karsten Franke
The identification of major uptake pathways in plants is an important factor when evaluating the fate of manufactured nanoparticles in the environment and the associated risks. Using different radiolabeling techniques we were able to show a predominantly particulate uptake for CeO2 nanoparticles in contrast to a possible uptake in the form of ionic cerium. Ce-ing and doing: Two radiolabeling techniques for CeO2 nanoparticles were developed which produce radiolabeled [139Ce]CeO2 nanoparticles with different activity release kinetics upon dissolution. Using these showed a predominantly particular uptake and translocation route of CeO2 along the water current in plants, with a slow dissolution inside the plant.
