Evaluating Neutral PFAS for Potential Dermal Absorption from the Gas Phase

14 Mar 2023 | Environ Sci Technol

11 occupationally-relevant PFAS were estimated to be absorbed into the body more efficiently through dermal absorption than inhalation, suggesting that PFAS dermal absorption from the gas phase may need to be included in PFAS exposure guidelines.

Current per- and polyfluoroalkyl substance (PFAS) research points to a growing threat in animals

13 Mar 2023 | J Am Vet Med Assoc

The author states that health-based guidance values are needed for infant PFAS exposures for the myriad of legacy and emerging PFAS—not just the four drinking water screening values used in the U.S.

Emerging and Legacy Perfluoroalkyl Substances in Breastfed Chinese Infants: Renal Clearance, Body Burden, and Implications

2 Mar 2023 | Environ Health Perspect

Legacy and novel short-chain PFAS were found widespread in human breast milk, with 6:2 Cl-PFESA displaying a median half-life of 49 years in infants.

Per-and Polyfluoroalkyl Substances in Toilet Paper and the Impact on Wastewater Systems

1 Mar 2023 | ACS

Six PFAS were detected in toilet paper samples, and the most prevalent one, 6:2 diPAP, was estimated to contribute between 4% – 89% of 6:2 diPAP concentrations in sludge.

28 Feb 2023 | Environ Sci Technol

Exposure to the newer PFAS F-53B and OBS resulted in lower rates of activity as well as induced physiological changes within a human model species.

Association between polyfluoroalkyl substances exposure and sex steroids in adolescents: The mediating role of serum albumin

27 Feb 2023 | Ecotoxicol Environ Saf

Mixed exposure to PFAS was associated with endocrine disruption in developing adolescents, especially in girls, and serum albumin was found to play a possible mediating role in this association.
