The study is focused on the spatial distribution of lanthanide into different plant tissues of the model plant in the aquatic environment compared to lanthanide salts. Commonly used toxicology endpoints, such as root growth or total length of the root system were used to evaluate the toxicity effect. Cross-sections from different plant tissues were prepared for monitoring of depth distribution of UPCNs. The spatial distribution of selected lanthanides was established by Laser-Induced Breakdown Spectroscopy (LIBS) with tens of micrometer scale which is a suitable resolution for first monitoring study. The study provides information about the underlying mechanism of water-soluble UPCNs, dispersed in aqueous medium, uptakes by model plants. We also discussed possible risk assessment and toxicity of UPCNs.
