Tackling PFAS, From Wastewater to Tap Water

Credit: USEPA

Tackling “forever chemicals” in tap water (start time: 6:11): In this week’s science show we discuss the scientific findings and societal implications of a new study showing of dangerous PFAS (per- and polyfluoroalkyl substances) in treated wastewater that ends up in the drinking water of more than 20 million Americans. We also explore the public health risks of these  cancer-causing and otherwise toxic compounds–found in so many consumer products, including water-resistant clothing–and what’s being done on the national, state and local fronts to protect source water and our health. Listen to host Susan Moran’s interview with Kate Dunlap, the drinking water quality manager for the City of Boulder; and Bridger Ruyle, a research assistant professor of environmental engineering at New York University and lead author of the new PFAS study.

Move Your Body!

On today’s show Beth plays portions of a chat (full version here; actual talk starts at 1 minute in) she had with Katy Bowman who is a nationally-known biomechanist, author, and movement educator. They spoke at the Boulder Bookstore, where Katy discussed her new book, My Perfect Movement Plan. Bowman combines big-picture lessons on biomechanics, kinesiology, physiology, and natural human movement with simple and practical solutions and exercises to get all your body parts moving better. Her ‘Movement is Nutrition’ approach addresses the need of our bodies for a wide variety of daily movements in order to work well. Building off the idea that movement is more than exercise, Katy wants to us to create a movement diet that will provide both macro- and micronutrients that the body needs in order to stay well and work well.

Plastic Pollution: Sources, Impacts, Solutions

Credit: Monterey Bay Aquarium

Tackling Plastic Pollution (start time: 3:50) In this week’s show, host Susan Moran interviews science journalists Fionna Samuels, an assistant editor at Chemical & Engineering News, a publication  of the American Chemical Society; and Priyanka Runwal, an associate editor at C&EN. Along with  other colleagues, they wrote cover articles in the November 28th issue of C&EN on the sources and impacts of plastic pollution. Indeed, plastics, mostly made from fossil fuels, are wreaking havoc on our environment and potentially our bodies. Although it’s still unclear precisely how much our bodies are accumulating tiny plastic particles, and to what effect, scientists are warning that nanoplastics could be altering our brains, our reproductive system, and our metabolism. Recently, representatives from many nations, including the United States, met to reach a first-of-its-kind United Nations global treaty to tackle plastic pollution. They failed. But outside the realm of treaties, a lot is being done, and far more can be done, to reduce the production, use, and waste of plastic.
