En ny front har öppnats i den pågående tvisten om säkerheten hos kemikalier som används i non-stick-beläggningar. Konflikten kretsar nu kring reklampåståenden om PFAS-ämnen.
Striden om evighetskemikalier i köksutrustning involverar kändiskockar, stora tillverkare och delstatliga lagstiftande församlingar. Dessa grupper har redan drabbat samman på flera fronter gällande hälsoeffekterna av de ämnen som allmänt är kända som PFAS.

Researchers at Flinders University say they have developed an adsorbent material that removed more than 98% of short- and long-chain PFAS—including hard-to-capture short-chain variants—in laboratory flow-through tests using model tap water. The approach embeds nano-sized molecular cages into mesoporous silica and, in the experiments reported, could be regenerated while remaining effective over at least five reuse cycles.
The South Korean government established a joint task force with local industry officials on Wednesday to respond to the European Union's plan to phase out per- and polyfluoroalkyl substances (PFAS). The EU plans to publish a draft opinion on PFAS restrictions later this month, aiming for universal adoption by 2027.

The Trump administration announced plans to rescind restrictions on four types of PFAS in drinking water and extend compliance timelines for two others. Officials described the move as a realistic approach to protecting public health.
A study from the University of Bonn shows that kitchen sponges shed microplastics during regular use. Emissions vary by sponge type, but water consumption drives most of the environmental impact from hand dishwashing.

Researchers from the University of Colorado Boulder have detected medium-chain chlorinated paraffins (MCCPs) in the air over an agricultural region in Oklahoma, marking the first such finding in the Western Hemisphere. The toxic pollutants likely originated from biosolid fertilizers applied to nearby fields. The discovery came unexpectedly during a study on airborne particles.
