However, robust quantitative translation between administered experimental doses and plausible human internal burdens remains highly uncertain due to variability in exposure assessment assumptions, limited size-resolved data on internal PET burdens in humans (particularly for the nanoscale fraction), and methodological constraints in detecting and characterising sub-micrometre particles in complex biological matrices
