Estimated serum levels of perfluorooctanoic acid (PFOA) in a woman exposed in utero, via breastfeeding for 12 months and subsequently via food intake for 49 years to 0.187 ng/kg bw per day

• The level peaks at 9 months of breastfeeding around 9.1 ng/mL, decreases and then increases to 2.0 ng/mL at 35 years and a steady state level at 50 years around 2.1 ng/mL.
