This ScienceHub entry contains a zip file with the pharmacokinetic modeling code used for the linked publication, "Challenges for extrapolation of risk from ingestion to inhalation exposure for per- and polyfluorinated alkyl acids and their precursors." The model code is written in R with a .model file written in the MCSim language. The inhalation pharmacokinetic model builds on a previous publication of Bernstein et al., "A Model Template Approach for Rapid Evaluation and Application of Physiologically Based Pharmacokinetic Models for Use in Human Health Risk Assessments: A Case Study on Per- and Polyfluoroalkyl Substances" https://doi.org/10.1093/toxsci/kfab063
