Polymer-coated electrode detects PFAS in water
News
25 Nov 2020 | C&EN
Instead of bringing water samples back to the lab for analysis, researchers would like to have a continuous field monitor. ”We knew that electrochemistry potentially would be sensitive and selective enough to detect PFAS, and it’s rather inexpensive,” Dick says.

Assessing Human Health Risks from Per- and Polyfluoroalkyl Substance (PFAS)-Impacted Vegetable Consumption: A Tiered Modeling Approach.
Science
25 Nov 2020 | Environ Sci Technol
A hazard analysis based on real-world PFAS-contaminated groundwater data found that water-to-crop transfer is an important exposure pathway for communities with PFAS-impacted irrigation water.

[Informational Webinar] EPA's Innovative Ways to Destroy PFAS Challenge
Events
23 Nov 2020
EPA is partnering with the other stakeholders, to co-sponsor a technical challenge regarding the destruction of PFAS. The challenge asks solvers to submit detailed plans for a non-thermal way of destroying PFAS in AFFF, while creating the least amount of potentially harmful byproducts with a $50,000 prize.

Suggestions for Improving the Characterisation of Risk from Exposures to Per and Polyfluorinated Alkyl Substances (PFAS)
Science
22 Nov 2020 | Environ Toxicol Chem
Here we propose methods that consider maximizing the use of disparate data streams, seeking patterns, and proposing biological-based approaches to evidence integration towards informed criteria development.

Comparison of extraction methods for per- and polyfluoroalkyl substances (PFAS) in human serum and placenta samples-insights into extractable organic fluorine (EOF)
Science
22 Nov 2020 | Anal Bioanal Chem
Results showed that performance, in terms of recovery, differed between the extraction methods for different PFAS; different extraction methods resulted in different EOF concentrations indicating that the choice of extraction method is important for target PFAS and EOF analysis.
