Influence of Cerium Oxide Nanoparticles on Two Terrestrial Wild Plant Species
Most current studies on the relationships between plans and engineered nanomaterials (ENMs) are focused on food crops, while the effects on spontaneous plants have been neglected so far. However, from an ecological perspective, the ENMs impacts on the wild plants could have dire consequences on food...

Most current studies on the relationships between plans and engineered nanomaterials (ENMs) are focused on food crops, while the effects on spontaneous plants have been neglected so far. However, from an ecological perspective, the ENMs impacts on the wild plants could have dire consequences on food webs and ecosystem services. Therefore, they should not be considered less critical. A pot trial was carried out in greenhouse conditions to evaluate the growth of <i>Holcus lanatus</i> L. (monocot) and <i>Diplotaxis tenuifolia</i> L. DC. (dicot) exposed to cerium oxide nanoparticles (<i>n</i>CeO<sub>2</sub>). Plants were grown for their entire cycle in a substrate amended with 200 mg kg<sup>−1</sup><i>n</i>CeO<sub>2</sub> having the size of 25 nm and 50 nm, respectively. <i>n</i>CeO<sub>2</sub> were taken up by plant roots and then translocated towards leaf tissues of both species.
