• 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.

• Getting control of PMT and vPvM substances under REACH

  Events

  25 Mar 2021

  This workshop will feature case studies of selected, emerging PMT/vPvM substances that are attracting increasing attention (e.g. ChemSEC's SIN List).

• Hydrolysis of FTOH precursors, a simple method to account for some of the unknown PFAS

  Science

  3 Mar 2021 | Chemosphere

  Analysis of extracts of textile samples with preliminary hydrolysis and without it showed up to 1300-fold higher level of “hidden” FTOHs.

• Regulating PFAS as a Chemical Class under the California Safer Consumer Products Program

  Science

  22 Feb 2021 | Environ Health Perspect

  In this commentary, we present the rationale adopted by the State of California's DTSC for regulating PFAS as a class in certain consumer products.

• Response to “Comment on Scientific Basis for Managing PFAS as a Chemical Class

  Science

  1 Feb 2021 | Environ. Sci. Technol

  Here we are responding to the comment by Singh and Papanastasiou who disagree with a class-based approach to PFAS and build their argument around hydrochlorofluorocarbons.

• Comparison of currently available PFAS remediation technologies in water: A review

  Science

  28 Jan 2021 | J Environ Manage

  In this review, extra consideration is given to novel advanced techniques for PFAS including short chain PFAS removal, and compare their efficiencies, effectiveness, energy use, sustainability, cost, and simplicity in laboratory scale to field applications.

• Suspect and Nontarget Screening Revealed Class-Specific Temporal Trends (2000-2017) of Poly- and Perfluoroalkyl Substances in St. Lawrence Beluga Whales

  Science

  20 Jan 2021 | Environ Sci Technol

  Short-chain PFAS were found in beluga whales which indicates that the continuous emissions of unregulated PFAS into the environment.

• Atmospheric particulate represents a source of C8–C12 perfluoroalkyl carboxylates and 10:2 fluorotelomer alcohol in tree bark

  Science

  18 Jan 2021 | Environ. Poll.

  Overall, this study provides the first evidence that atmospheric particulate is an obvious source of C8–C12 PFCAs and 10:2 FTOH in tree bark.

• [Blog] How many of us are drinking toxic forever chemicals?

  News

  12 Jan 2021 | BioMed Central

  A recent study found that nearly 100 million people in 16 out of 66 cities investigated in China are likely using drinking water that exceeds 20 ppt for the sum of five PFAS (PFOA, PFOS, PFHxS, PFHpA, and PFNA), new maximum contaminant level set by the U.S. state of Vermont.

• Deterministic risk assessment of firefighting water additives to terrestrial organisms

  Science

  12 Jan 2021 | Environ Sci Pollut Res Int

  A number of PFAS-free firefighting water additives were found to pose a hazard to terrestrial organisms based on a worst-case exposure scenario of direct application at the greatest recommended application rate for a class A fire (e.g., wood, paper).

• Solvent-free fabrication of tough self-crosslinkable short-fluorinated copolymer nanocoatings for ultradurable superhydrophobic fabrics

  Science

  23 Dec 2020 | Chem. Eng. J

  A short-chain PFAS nanocoating was engineered as an eco-friendly durable water-resistant fabric.

• The new generation PFAS C6O4 does not produce adverse effects on thyroid cells in vitro

  Science

  22 Dec 2020 | J Endocrinol Invest

  PFAS C6O4 was found to not significantly impair thyroid cells in a non-systemic study.

• Investigation targets discharges of next-generation 'forever chemicals' from 3M's Cottage Grove plant

  News

  18 Dec 2020 | Star Tribune

  State and federal pollution regulators are investigating 3M Co.'s reporting on next-generation "forever chemicals" discharged from its Cottage Grove plant into the Mississippi River, even as Minnesota struggles to address ever-growing contamination from the original versions the manufacturer no longer makes.
