February 2021 Edible nutrient-amended sorbents can reduce bioavailability and toxicity of per- and polyfluoroalkyl substances (PFAS) ingested via contaminated water and food, found NIEHS grantees. Clay-based sorbents bind toxins in the stomach and intestine, thereby reducing exposure. Here, the researchers tested whether adding the common nutrients carnitine and choline to a clay-based sorbent would enhance PFAS adsorption. [Full Text]
