Utilization of analytical instrumental methods in phytotoxicity testing of nanoparticles
Original language description
In this work, we focused on several analytical instrumental methods utilization and the benefits of their outcomes in phytotoxicity assessment. Two model plants - Allium cepa L. and Lemna minor L. were used to test five types of cadmium Quantum Dots (QDs). In the first study, L. minor was used to test cadmium telluride QDs capped with two coating ligands: glutathione (GSH) or 3-mercaptopropionic acid (MPA). Macroscopic toxicity endpoints number of fronds and fresh weight of L. minor were determined after 168-hour exposure and growth rate inhibition and final biomass inhibition were evaluated. The next objective was to determine total content of Cd in plants using Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES). Laser-Induced Breakdown Spectroscopy (LIBS) with 200 µm lateral resolution was employed to obtain two-dimensional maps of Cd spatial distribution in L. minor fronds. Finally, L. minor fronds were subjected to transmission electron microscopy (TEM) to examine QDs ability to pe
