‘Forever Chemicals’ Ban Could Impact Millions of Americans
News
10 Jul 2024 | Newsweek
The proposed Pennsylvania House Bill 2238, which has not yet been passed, hopes to outlaw the use of PFAS chemicals in cleaning products, carpets, cookware, cosmetics, dental floss, food packaging, infant and children's products, menstrual products, and textiles, among others, by 2027.

Combining Advanced Analytical Methodologies to Uncover Suspect PFAS and Fluorinated Pharmaceutical Contributions to Extractable Organic Fluorine in Human Serum (Tromsø Study).
Science
10 Jul 2024 | Environ. Sci. Technol.
Traditional PFAS monitoring cannot fully account for extractable organic fluorine (EOF) levels in human blood, but recent screening of human serum in Norway revealed that fluorinated pharmaceuticals significantly contribute to EOF, closing the mass balance for some but not all samples.

Lithium-ion battery components are at the nexus of sustainable energy and environmental release of per- and polyfluoroalkyl substances
Science
8 Jul 2024 | Nature
A cradle to grave evaluation of PFAS in lithium ion batteries found contamination near manufacturing sites from PFAS with similar ecotoxicity and treatability to PFOA, a highly toxic legacy PFAS. This work underscores the importance of lifecycle impacts when evaluating low-carbon energy technologies.

Impacts of rapidly urbanizing watershed comprehensive management on per-and polyfluoroalkyl substances pollution: based on PFAS “diversity” assessment
Science
8 Jul 2024 | Water Research
In rapidly urbanizing Shenzhen, China, watershed comprehensive management failed to reduce overall PFAS pollution and diversity, often exacerbating contamination through river sediment dredging, though it improved point source pollution and revealed new high-risk PFAS, highlighting the need for better regulatory measures.

Combining Freshwater Irrigation with Vegetable Selection to Mitigate the Occurrence of Per-and Polyfluoroalkyl Substances in Edible Vegetable Parts in a Semiarid Farmland in Northwestern China
Science
2 Jul 2024 | ACS ES&T Water
Reclaimed-water irrigation can introduce PFAS into farmlands, but switching to freshwater irrigation reduces PFAS levels in vegetables, with carrots and potatoes accumulating fewer contaminants than cabbage and pak choi, highlighting the importance of cleaner irrigation water for growing nonleafy vegetables.
