The train derailment in East Palestine, OH, created a state of uncertainty over how severe the contamination is and the risks posed by acute and chronic exposure to the chemicals that spilled and combusted. At the same time, we’re living through a period of scientific and industrial history that seems to drown us in information about what is and isn’t toxic. And it feels like all of us, not just residents of eastern Ohio, ought to have a clear sense of which products and pollutants pose real risks to us. How long can we expect the residents of East Palestine to remain exposed to toxic air and water? Even if government officials say the air and water is safe, can Ohioans rest easy? And generally, how can any of us process the deluge of information we receive about the risks of various substances and foods that we encounter or ingest all the time? Are microplastics actually killing us?! Is beef highly carcinogenic?! Or is it essential for good health?! Or neither?! It all becomes pretty overwhelming, and it’s easy to feel unsettled by, but also a bit numb to, so many dire warnings in the news, on social media, and elsewhere. Tufts Medical School Professor Dr. Jeffrey Griffiths joins host Brian Beutler to discuss how we can live happy lives without being anxious all the time, but with enough awareness and knowledge to protect ourselves from real dangers.
