Prenatal Per- and Polyfluoroalkyl Substance Exposures and Longitudinal Blood Pressure Measurements in Children Aged 3 to 18 Years: Findings From a Racially and Ethnically Diverse US Birth Cohort
Science

Scientists’ statement on the chemical definition of PFASs
Science
10 Jun 2025 | Environ. Sci. Technol. Lett.
The authors raise concerns about ongoing efforts to redefine PFAS and potentially exclude certain PFASs included under the 2021 OECD definition of PFAS chemicals. As there is no evidence to indicate that the OECD definition is flawed or problematic or ambiguous, there is no need for a new chemical definition.

Decorative cosmetics and skin care products contribute significantly to short-chain perfluoroalkyl carboxylates exposure
Science
5 Jun 2025 | J Hazard Mater
Tests on 3-D human skin models show that decorative cosmetics and skin-care products permit short-chain PFAS, such as by PFBA, to pass through skin efficiently, pushing daily intakes up to about 0.8 ng per kilogram of body weight and making dermal contact responsible for roughly 40 % of total PFOA exposure among regular users, findings that strengthen the case for tighter limits on PFAS in personal-care items.
