Forever Chemicals

• Niveaus van PFAS in eieren van noordse jan-van-masten in Canada zijn met maximaal 74% gedaald gedurende een onderzoeksperiode van 55 jaar • De concentraties van enkele van de gevaarlijkste PFAS-verbindingen zijn drastisch gedaald in Canadese zeevogel-eieren, wat volgens de auteurs van een nieuwe peer-reviewed studie illustreert hoe effectief regelgeving is. • Onderzoekers bekeken de PFAS-niveaus in de eieren van noordse jan-van-masten in het St Lawrence Seaway-bekken over een periode van 55 jaar. PFAS-niveaus schoten omhoog vanaf de jaren 60 tot aan de piek van het gebruik van de chemicaliën eind jaren 90 en begin jaren 2000, om daarna te dalen. Lees verder...

• 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...
