Determinants of serum concentrations of perfluoroalkyl acids (PFAAs) in school children and the contribution of low-level PFAA-contaminated drinking water
18 Feb 2020 | Environ Sci Process Impacts
The drinking water variable was found to be 16% (PFOA) to 78% (PFHxS) of the variation in serum PFAA concentrations, suggesting that low-level-contaminated drinking water is a significant source of exposure for children in Sweden.
