PFAS on Atmospheric Aerosol Particles: A Review
Science
12 Apr 2022 | Environ Sci Process Impacts
Long-term monitoring of PFAS on the particulate matter should be expanded to include under-sampled regions of the world and further non-targeted analysis is needed to identify novel PFAS structures as PFAS manufacturing and regulations continue to evolve.

Effect of Plasma and Blood Donations on Levels of Perfluoroalkyl and Polyfluoroalkyl Substances in Firefighters in Australia: A Randomized Clinical Trial
Science
12 Apr 2022 | JAMA Netw Open
Regular blood or plasma donations result in a significant reduction in serum PFAS levels for participant firefighters with a baseline PFOS level of 5 ng/mL or more; plasma donations reduced levels more quickly than blood donations.

Perfluorinated alkyl substances in Canadian human milk as part of the Maternal-Infant Research on Environmental Chemicals (MIREC) study
Science
12 Apr 2022 | Sci Total Environ
Primiparous women had elevated PFAS concentrations in milk relative to women who had children previously, and the region of material birth did not influence PFAS concentrations.

Perfluorooctanoate and perfluorooctane sulfonate in umbilical cord blood and child cognitive development: Hamamatsu Birth Cohort for Mothers and Children (HBC Study)
Science
6 Apr 2022 | Environ Int
Measurements of PFOA and PFOS in the cord blood of nearly 600 mother-infant pairs found mixed associations between PFAS concentrations and cognitive development.

Temporal Trends of Organochlorine- and Perfluorinated Contaminants in a Terrestrial Raptor in Northern Europe over 34 Years (1986-2019)
Science
31 Mar 2022 | Environ Toxicol Chem
Most legacy organochlorines and PFOS have not reached lower, stable background levels, and voluntary elimination of PFCAs still have not resulted in declining levels in tawny owls in central Norway.

Years after flags, Wolverine Worldwide plant caught in PFAS probe
News
30 Mar 2022 | MLive
Investigators have finally made their way to a Wolverine Worldwide facility where the company manufactured shoe parts near the Rogue River, five years after the initial discovery of widespread toxic ‘forever chemical’ pollution in the northern Kent County suburbs.

Per- and polyfluoroalkyl substances (PFASs) in the blood of police and Beagle dogs from Harbin, China: Concentrations and associations with hematological parameters
Science
28 Mar 2022 | Chemosphere
Dominant PFAS in the blood of dogs were found to be PFOA, PFBA, and PFOS, and PFAS exposure was linked to many changes in biochemical blood parameters like cholesterol.

Perfluoroalkyl Substances and Incident Natural Menopause in Midlife Women: The Mediating Role of Sex Hormones
Science
22 Mar 2022 | Am. J. Epidemiol.
Participants with higher PFAS concentrations had a shorter time to natural menopause, and the effect of PFAS may be partially explained by variations in hormone concentrations.

Understanding Public Perceptions of Per- and Polyfluoroalkyl Substances: Infodemiology Study of Social Media
Science
21 Mar 2022 | J Med Internet Res
Government agencies can use social media research to understand the community sentiment on PFAS and then use social media to dispel misinformation, communicate scientific findings, and provide resources for relevant public health services.

[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.
