Forever Chemicals

I livelli di Pfas nelle uova di @@northern gannet@@ in Canada sono diminuiti fino al 74% in un periodo di studio di 55 anni. I livelli di alcuni dei composti Pfas più pericolosi sono scesi drasticamente nelle uova di uccelli marini canadesi, il che, secondo gli autori di un nuovo studio sottoposto a peer-review, illustra l'efficacia delle normative. I ricercatori hanno analizzato i livelli di Pfas nelle uova di @@northern gannets@@ nel bacino della @@St Lawrence Seaway@@ in un arco di 55 anni. I livelli di Pfas sono impennati dagli anni '60 fino al picco di utilizzo di queste sostanze chimiche tra la fine degli anni '90 e i primi anni 2000, per poi diminuire. Continua a leggere...

• Common PFAS 'forever chemicals' exposure linked to reduced bone density in children, potentially causing lifelong skeletal weakness. • Peer-reviewed study from The Endocrine Society shows early-life contamination disrupts bone development before adulthood. • Prevalent in U.S. water supplies and consumer products, PFAS affect 99% of Americans, raising public health alarms per CDC data.

• A new study finds that exposure to PFAS (per- and polyfluoroalkyl substances)—chemicals used in non-stick coatings and water-resistant products—is linked to low bone density in teenagers. • The research, announced by the Endocrine Society, involved collaboration between the CDC, University of Cincinnati College of Medicine, University of Pennsylvania, Simon Fraser University, and George Washington University. • The finding adds to growing evidence that PFAS contamination poses significant health risks, particularly during critical periods of skeletal development in adolescence.

US test of 120 umbilical blood cord samples identified 42 Pfas compounds, which do not naturally break downSign up for the Breaking News US email to get newsletter alerts in your inboxNew peer-reviewed research shows fetuses likely have much higher levels of Pfas “forever chemicals” in their blood than previously thought.Testing of umbilical cord blood typically looks for a small number of common Pfas compounds, like Pfoa and Pfos. However, thousands of Pfas exist, and a new Mount Sinai study tested 120 umbilical blood cord samples that were previously found to contain up to four compounds. Continue reading...
