Many health experts and advocates say breastfeeding is the best choice for babies but the threat of passing on contamination from PFAS is prompting new questions. Maryann Jacobs’ heart was pounding as she opened her letterbox one snowy morning last year in Hoosick Falls, a town in upstate New York bordering Vermont and Massachusetts. Inside that envelope was devastating news that her baby son Oliver’s results were worse than she had feared. More:

Many Americans fill up a glass of water from their faucet without worrying whether it might be dangerous. But the crisis of lead-tainted water in Flint, Mich., showed that safe, potable tap water is not a given in this country. Now a study from the Environmental Working Group (EWG), a nonprofit advocacy organization, reveals a widespread problem: the drinking water of a majority of Americans likely contains “forever chemicals.” More:

For the last two decades, the European Union has played a leadership role in tackling the risks hazardous chemicals pose to our health and environment. It has now proposed a new vision for a "toxic-free environment" and published a strategy for moving the EU towards that goal. Just as its current policies have inspired imitation, it’s likely that these new policies will drive significant changes in the U.S. and elsewhere. More:

Shredded carpet waste is increasingly used in equestrian riding centers. This waste is used along with polyflakes (a residual product from the textile industry) and geopad (shredded geotextile fabric). Crushed used car tires are applied to sports fields and playgrounds; this is what makes up the so-called rubber granulate. More:

The chemicals in our environments, while sometimes useful, can also hurt us. Materials like asbestos fibers can move through the air and into the lungs in the form of tiny particles, causing long-term damage to human tissues. But free-floating, harmful chemicals are also emitted from the furniture, wallpaper, flooring, and household items around us. And these chemicals are entering our bodies, damaging them in many different ways. More:

A Michigan-based environmental group has found many nonstick pans are coated with a chemical from the PFAS family. The group tested 14 cooking pans and 10 baking pans from different retailers in different price ranges. It found 77% of the cooking pans were coated with PTFE, polytetrafluoroethylene. 20% of the baking pans had PTFE. More:
