Removal of poly- and perfluoroalkyl substances (PFAS) from water by adsorption: Role of PFAS chain length, effect of organic matter and challenges in adsorbent regeneration
Science
16 Jan 2020 | Water Res.
Short-chain PFAS found to absorb to organic material less efficiently making it harder to remediate from water.

Accumulation and phytotoxicity of perfluorooctanoic acid and 2,3,3,3-tetrafluoro-2-(heptafluoropropoxy)propanoate in Arabidopsis thaliana and Nicotiana benthamiana
Science
16 Jan 2020 | Environ. Pollut.
GenX was found to be bioaccumulative, and that accumulation likely inhibits plant growth and photosynthesis.

The emerging PFOS alternative OBS exposure induced gut microbiota dysbiosis and hepatic metabolism disorder in adult zebrafish
Science
16 Jan 2020 | Comp. Biochem. Physiol. C Toxicol. Pharmacol.
The PFAS alternative, sodium ρ-perfluorous nonenoxybenzene sulfonate, was found to change gut bacteria levels and negatively impact metabolism.

Association between serum concentrations of perfluoroalkyl substances (PFAS) and expression of serum microRNAs in a cohort highly exposed to PFAS from drinking water
Science
15 Jan 2020 | Environ. Intern.
Epigenetic mechanisms were proposed as a mode of action of PFAS toxicity in drinking water.

Highly fluorinated chemicals in functional textiles can be replaced by re-evaluating liquid repellency and end-user requirements
Science
15 Jan 2020 | J. Cleaner Prod.
The best non-fluorinated DWRs have water repellency as good as fluorinated polymers in textiles.

Groups calling to have PFAS listed as hazardous chemicals by the EPA
News
15 Jan 2020 | KTUU-TV
Listing under RCRA will subject the chemicals to strict storage, transfer, and disposal requirements. It would also result in the automatic designation of these chemicals as hazardous substances under the federal Superfund law, unlocking clean-up dollars to address contaminated sites.

As more PFAS contamination is found, federal action becomes more urgent
News
15 Jan 2020 | BDN
As we’ve learned from the containment and removal of other hazardous substances, costs only grow as action is delayed.
