Impact/Purpose:
This report is primarily meant to serve as a learning tool for EPA scientists and risk assessors who may be less familiar with the field. In addition, this report can be informative to PBPK modelers within and outside the Agency, as it provides an assessment of the types of data and models that the EPA requires for consideration of a model for use in risk assessment.
Description:
This draft report of Approaches for the Application of Physiologically Based Pharmacokinetic (PBPK) Models and Supporting Data in Risk Assessment addresses the application and evaluation of PBPK models for risk assessment purposes. These models represent an important class of dosimetry models that are useful for predicting internal dose at target organs for risk assessment applications.
Topics covered include:
- the types of data required use of PBPK models in risk assessment,
- evaluation of PBPK models for use in risk assessment, and
- the application of these models to address uncertainties resulting from extrapolations (e.g. interspecies extrapolation) often used in risk assessment.
- a compilation of chemical partition coefficients and rate constants,
- algorithms for estimating chemical-specific parameters, and
- a list of publications relating to PBPK modeling.
