Ultra-Short-Chain PFASs in the Sources of German Drinking Water: Prevalent, Overlooked, Difficult to Remove, and Unregulated
Science
17 May 2022 | ES&T
Ultra-short-chain PFAS represent a major challenge in drinking water due to their high concentrations, greater mobility, and lack of remediation options, which shows that regulation through preventive measures is required to manage them.

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.
