- Abstract
Metal dioxide nanoparticles (NPs) are produced in ever-increasing amounts and widely used in industrial, medical and consumer products. They may pose potential risks to the environment. In this study we quantitatively evaluated the phytoavailability of CeO2NPs, ZrO2NPs and SiO2NPs to wheat (Triticum aestivum L.). Metal dioxide NPs showed distinct differences in uptake, with uptake rate constants of 90.2 ± 9.9, 12.2 ± 2.5, 0.4 ± 0.02 and 0.9 ± 0.1 L kg−1 h−1 for ZrO2NPs, CeO2NPs, SiO2NPs (13 nm) and SiO2NPs (25 nm), respectively. However, such difference cannot be generalized by single factor of NP characteristics and/or root damage. This study provides fundamental information for NP uptake by crop plants.
