Abstract EN
The aquatic plant Lemna gibba L.
was used to investigate and compare the toxicity induced by 30 nm nickel oxide nanoparticles (NiO-NPs) and nickel(II) oxide as bulk (NiO-Bulk).
Plants were exposed during 24 h to 0–1000 mg/L of NiO-NPs or NiO-Bulk.
Analysis of physicochemical characteristics of nanoparticles in solution indicated agglomerations of NiO-NPs in culture medium and a wide size distribution was observed.
Both NiO-NPs and NiO-Bulk caused a strong increase in reactive oxygen species (ROS) formation, especially at high concentration (1000 mg/L).
These results showed a strong evidence of a cellular oxidative stress induction caused by the exposure to NiO.
Under this condition, NiO-NPs and NiO-Bulk induced a strong inhibitory effect on the PSII quantum yield, indicating an alteration of the photosynthetic electron transport performance.
Under the experimental conditions used, it is clear that the observed toxicity impact was mainly due to NiO particles effect.
Therefore, results of this study permitted determining the use of ROS production as an early biomarker of NiO exposure on the aquatic plant model L.
