The higher concentration of both PFOA and PFOS in infants and young children for our population, exposed to PFOA mainly via drinking water, might be explained by a number of factors, including in utero exposure, high uptake by the child during breast-feeding, a relatively higher bioconcentration by the infant perhaps related to lower excretion, and a higher rate of water consumption relative to body size for children than for mothers.
