Analysis
This paper develops a toxicokinetic model to understand nanoplastic bioaccumulation, bridging animal experiments and human exposure. It highlights the importance of dietary intake and lipid content in determining organ-specific concentrations, particularly in the brain. The model's predictive power and the identification of dietary intake as the dominant pathway are significant contributions.
Key Takeaways
- •A unified toxicokinetic model is developed to predict nanoplastic bioaccumulation.
- •Dietary intake is identified as the dominant pathway for human exposure.
- •Brain emerges as a dominant sink due to lipid-mediated enrichment.
- •The model bridges short-term animal experiments and chronic human bioaccumulation.
Reference
“At steady state, human organ concentrations follow a robust cubic scaling with tissue lipid fraction, yielding blood-to-brain enrichment factors of order $10^{3}$--$10^{4}$.”
