Distribution of the results for concentrations of lower-bound sum of 4 and of 14 perfluoroalkyl substances (LB ∑4 PFAS and LB ∑14 PFAS), perfluorooctanesulfonic acid (PFOS), perfluorooctanoic acid (PFOA) and perfluorononanoic acid (PFNA)

Relationship to the tolerable weekly intake (TWI) of dietary intake with a statistically average weekly portion and recommended weekly portion of milk based on lower- and upper-bound mean and 95th percentile concentrations related to the TWI
