Long-term leaching of PFAS from contaminated agricultural soils in Germany
Science
19 Apr 2021 | J. Contam. Hydrol.
Analysis of field data over a time period of 12 years revealed no or slowly decreasing trends as well as seasonal fluctuations, likely due to the ongoing transformation of precursors and a seasonal influence on production rates of mobile PFAS.

Fluorine-Specific Detection Using ICP-MS Helps to Identify PFAS Degradation Products in Nontargeted Analysis
Science
19 Apr 2021 | Anal Chem
The feasibility of the detection of PFAS metabolites using a fluorine-specific detection was demonstrated using a model compound and can thus be applied to new experiments and unknown organofluorine-containing samples in the future.

For PFAS, is environmental persistence on its own enough to trigger regulation?
News
18 Apr 2021 | C&EN
California regulators intend to deem carpets and rugs treated with PFAS-based stain-resistant coatings as having “a hazard trait that can harm people or the environment.” That hazardous trait is persistence. Industry is pushing back against this rationale.
