Try to pronounce "per- and polyfluoroalkyl substances" in a hurry, and you soon understand why the usual tag for them is simply PFAS (pee-fass).
They are chemicals found in many chemicals, from polishes to teflon cookware to food wraps. And they are a source of concern, because they last a long time in the environment and in the human body.
So bring on the zebrafish. The Tanguay Lab at Oregon State University just got a major grant to study the toxicity of PFAS.
Robert Tanguay and Jennifer Field at the lab explain their testing procedures, and how zebrafish are involved.
