Nitrogen and nitrogen isotope data for wheat and barley exposed to CeO2 nanoparticles
The effects of cerium oxide nanoparticles (CeO2-NPs) on 15N/14N ratio (δ15N) in wheat and barley were investigated.  Seedlings were exposed to 0 and 500 mg CeO2-NPs/L (Ce-0 and Ce-500, respectively) in hydroponic suspension supplied with NH4NO3, NH4+, or NO3-.  N uptake and δ15N discrimination (i.e. differences in …
