[Invited Perspective] Current Breast Milk PFAS Levels in the United States and Canada Indicate Need for Additional Monitoring and Actions to Reduce Maternal Exposures
Science
28 Feb 2022
Addressing the higher breast milk concentrations from maternal exposure to PFAS in drinking water will require identifying contaminated drinking water sources and establishing health-protective PFAS drinking water guidelines that consider both exposures and risks to breastfed infants.

Current Breast Milk PFAS Levels in the United States and Canada: After All This Time, Why Don't We Know More?
Science
28 Feb 2022 | Environ Health Perspect
The authors emphasize the need to study PFAS in breast milk and found that all average estimated and measured breast milk PFOA and PFOS concentrations exceeded drinking water screening values for children, sometimes by more than two orders of magnitude.
