Trophic Mobility and Distinct Organ-Specific Toxicity of Rare Earth Oxide (REO) Nanoparticles in a Freshwater Food Chain

Key Points

• The aim is to assess the trophic mobility and organ-specific toxicity of rare earth oxide nanoparticles in freshwater ecosystems.
• Assessment of lanthanum oxide and cerium oxide nanoparticles in a freshwater food chain.
• Measurement of their toxicity across different organs in aquatic organisms.
• REO nanoparticles showed varying levels of toxicity in specific organs.
• Significant toxic effects were observed in certain aquatic species indicating potential ecological risks.
