Figure 8 is a line graph, plotting cumulative density, ranging from 0.0 to 1.0 in increments of 0.2 (y-axis) across log to the base 10 sum Perlfuorooctanoic acid equivalent concentration in serum (nanogram per milliliter), ranging from 0.0 to 2.5 in increments of 0.5 (x-axis). — Cumulative density plot of the sum PFOA Equivalent (PEQ) concentration in serum (ng/mL) from the 2017–2018 National Health and Nutrition Examination Survey (NHANES) study population, ages 12 and older ( $lowercase italic n equals 1929$ ).⁸² Note: The black line represents the sum PEQ of all PFAS [perfluorohexanoic acid (PFHxA), perfluorooctanoic acid (PFOA), perfluorononanoic acid (PFNA), perfluorohexane sulfonic acid (PFHxS), perfluoroocane sulfonic acid (PFOS), hexafluoropropylene oxide-dimer acid (HFPO-DA)] of which internal relative potency factors were derived.
