New research from UNC Gillings explores how dietary choices may influence the amount of #PFAS that accumulate in our bodies. ‘Forever chemicals’ sneak into the kitchen via nonstick pans — but also through processed foods and tap water.

We have reached 1.4 degrees celsius #globalheating according to NASA data (smooth black trend line). Breaching 1.5 is now inevitable. From now on the fight is to keep overshoot as small and short as possible.

I'm bowled over by how beautifully NewsHour distilled the story of the community I had the privilege of following for my book. A heartfelt thanks to William Brangham and his crew for lifting up the voices of residents and spreading awareness about the scourge of #PFAS.

"They had never really taken much interest in [] environmental issues. They spent their lives believing that there were systems in place to protect them, & now that trust had been completely shattered."

Great. "It’s one of a new class of herbicides designed to help farmers kill weeds that have developed resistance to popular chemicals like glyphosate"
Woohoo. 😒 😒 Looks like the EPA is going to approve another PFAS-laden pesticide called epyrifenacil. This is the 5th PFAS pesticide the EPA has approved in the past several months.
EPA Proposes Approving Fifth ‘Forever Chemical’ Pesticide
The agency also created a new website dedicated to explaining and defending its approval of farm chemicals that meet a commonly used definition of PFAS.

Hold My Beer: The Linkage between Municipal Water and Brewing Location on PFAS in Popular Beverages
Beer has been a popular beverage for millennia. As water is a main component of beer and the brewing process, we surmised that the polyfluoroalkyl substances (PFAS) presence and spatial variability in drinking water systems are a PFAS source in beers. This is the first study to adapt EPA Method 533 to measure PFAS in beer from various regions, brewery types, and water sources. Statistical analyses were conducted to correlate PFAS in state-reported drinking water, and beers were analyzed by brewing location. PFAS were detected in most beers, particularly from smaller scale breweries located near drinking water sources with known PFAS. Perfluorosulfonic acids, particularly PFOS, were frequently detected, with PFOA or PFOS above U.S. EPA’s Maximum Contaminant Limits in some beers. There was also a county–level correlation between the total PFAS, PFOA, and PFBS concentrations in drinking water and beers. Given that approximately 18% of U.S. breweries are located within zip codes with detectable PFAS in municipal drinking water, our findings, which link PFAS in beer to the brewery water source, are intended to help inform data-driven policies on PFAS in beverages for governmental agencies, provide insights for brewers and water utilities on treatment needs, and support informed decision-making for consumers.
