A multi-platform approach for the comprehensive analysis of per-and polyfluoroalkyl substances (PFAS) and fluorine mass balance in commercial ski wax products
Science
21 May 2024 | Analytica Chimica Acta
The fluorine content of ski waxes was tested, finding that while traditional analytical methods identified only a small fraction of fluorine as extractable organic fluorine, the majority remained unidentified, suggesting the presence of other PFAS not detected by standard techniques, which highlights the need for more comprehensive analysis methods in assessing PFAS exposure risks in consumer products.

Occurrence and Fate of Per-and Polyfluoroalkyl Substances (PFAS) in Atmosphere: Size-Dependent Gas-Particle Partitioning, Precipitation Scavenging, and Amplification
Science
16 May 2024 | Environ. Sci. Technol.
Researchers in Shijiazhuang, China examined the distribution of PFAS in the atmosphere, finding that FCAs were the most prevalent, with their concentrations linked to the organic matter fraction across various particle sizes. Temperature influenced gas-particle partitioning and precipitation played a key role in removing PFAS from the atmosphere, despite temporary increases during rainfall events.
