Elucidating the role of dissolution in CeO2 nanoparticle plant uptake by smart radiolabeling

The identification of major uptake pathways in plants is an important factor when evaluation 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 (NPs) in contrast to a possible uptake in the form of ionic cerium.
