A High-Throughput Toxicity Screen of 42 Per- and Polyfluoroalkyl Substances (PFAS) and Functional Assessment of Migration and Gene Expression in Human Placental Trophoblast Cells
Science
1 Jun 2022 | Front. Toxicol.
The placenta is potentially a direct target of PFAS exposure and indicate that trophoblast cell gene expression and function are disrupted at PFAS levels well below the predetermined cell mortality level.

Invited Perspective: The Promise of Fit-for-Purpose Systematic Evidence Maps for Supporting Regulatory Health Assessment
Science
17 May 2022 | EHP
A primary goal of systematic evidence maps (SEMs) in environmental health is to gather large amounts of data to support deeper scientific analyses and decision-making that protects public health and the environment. SEMs can be extremely useful for assessing large chemical classes, such as PFAS. However, a comparison of two different SEM approaches highlights that many available PFAS studies might not be considered in the U.S. EPA health assessments.

Fluorine Mass Balance Analysis and Per-and Polyfluoroalkyl Substances in the Atmosphere
Science
17 May 2022 | J. Hazard. Mater.
Ultra-short-chain PFAS were identified as the predominant components in outdoor air and organofluorine compounds were found to concentrate indoors in fine particles. A fluorine mass balance analysis revealed that up to 99% of PFAS in the atmosphere are unidentified.
