Overview
- Lund University researchers reported Thursday that children with very high prenatal exposure to PFAS in Ronneby, Sweden, had a higher rate of clinically diagnosed asthma.
- A Michigan State University study found adults with higher PFAS in their blood produced fewer COVID-19 antibodies after vaccination, which signals a weaker immune response.
- In Westminster, Massachusetts, companies ordered to extend water lines after extreme PFAS contamination have missed key deadlines, leaving many homes reliant on filters and bottled water.
- A University of Wisconsin review of highly visited PFAS websites found most failed to give clear, upfront steps to reduce exposure and often buried essential details behind links.
- PFAS are long‑lasting chemicals used in products and firefighting foams that build up in water and people, and the EPA in 2024 set a 4‑parts‑per‑trillion drinking water limit for PFOA and PFOS while many households add reverse osmosis units that can cut these compounds by about 98 to 99 percent.
