Toxicity Criteria

What are the toxicokinetic extrapolations (considerations of species and gender differences; approaches for animal-human extrapolation and dose response modeling considerations) we should be using in the development of the toxicity basis for criteria?

Uncertainty

How do we validate exposure and uptake? How do we consider sensitivity and uncertainty in exposure and effects assessment and how they affect the differences in jurisdictional criteria?

Measuring versus Modeling

How can we can include consideration of relationship between external exposure (e.g., concentration in drinking water or other media) and internal dose (e.g., blood serum level) of PFAS in risk characterization? Should we rely on [...]
