Occurrence, profiles, and ecotoxicity of poly- and perfluoroalkyl substances and their alternatives in global apex predators: A critical review
Science
11 May 2021 | J of Env Sci
PFOS was the dominant PFAS found in the top predators, followed by PFUnDA, and the proportions of odd C-chain length PFCAs were higher than adjacent even C-chain length PFCAs.

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.

Exploring Unknown Per- and Polyfluoroalkyl Substances in the German Environment – the Total Oxidizable Precursor Assay as Helpful Tool in Research and Regulation
Science
7 Apr 2021 | Sci. Total Environ.
Time trend analysis showed decreasing trends for most detected PFAS since 2005 with the results demonstrating that target analysis detects only a minor fraction of the PFAS burdens in environmental samples.
