PFAS River Export Analysis Highlights the Urgent Need for Catchment-Scale Mass Loading Data
Science
19 Feb 2024 | ES&T Letters
A study of a European river system found that wastewater treatment works contribute significantly to the total PFAS levels exported from the river, but that additional PFAS sources must also be eliminated in order to meet water quality improvement goals.

On the fluoropolymers and ultra-short PFAS topic: Aqueous Leaching of Ultrashort-Chain PFAS from (Fluoro)polymers: Targeted and Nontargeted Analysis
Science
19 Feb 2024 | ES&T Letters
All tested fluoropolymers, as well as non-fluorinated alternatives like PEEK, were found to leach C2-C4 PFCAs, likely related to their production such as processing aids, residuals, and inhibitors. This indicates that fluoropolymers and other plastics can emit short chain PFAS into the environment.

EPA Proposes New Set of Rules to Regulate PFAS Under RCRA
Policy
15 Feb 2024
The U.S. EPA proposed two regulations that would add nine PFAS to the list of Resource Conservation and Recovery Act "hazardous constituents" and broaden the definition of "hazardous waste" applicable to corrective action at waste facilities, which taken together, would significantly enhance EPA's authority to regulate PFAS.

Development of a method using QuEChERS and LC–MS/MS for analysis of per-and polyfluoroalkyl substances in rice matrix
Science
10 Feb 2024 | Food Chemistry
To ensure food safety, a method combining QuEChERS extraction and LC-MS/MS was developed to detect 35 PFAS in rice, finding that instant rice microwaved in its packaging had lower PFAS levels compared to instant rice boiled in its packaging.
