Figure 2.

Line graph plotting serum PFOA in nanograms per milliliter (y-axis) across time in years (x-axis), where serum prediction is 9.67. Starting serum PFOA concentration is 2.08 nanograms per milliliter. Water PFOA concentration is 70 parts per trillion. Serum PFOA concentration from other ongoing exposures is 2.08 nanograms per milliliter. Half-life of PFOA in serum is 2.3 years. Steady-state ratio for serum is to water concentrations is 114. Predicted steady-state serum PFOA concentration is 10.06 nanograms per milliliter.
