Figure 1. Overview of the PFAS TK model processes for predicting population serum PFAS concentrations ([PFAS]) from drinking water PFAS. Population distributions of chemical-specific parameters and exposure factors, some of which change with age, are combined using Monte Carlo simulation to predict the distribution of serum [PFAS] in a specified population. PFAS: Per- and polyfluoroalkyl substances; TK: toxicokinetic.
