War Against Weeds: S11 E2 - Toxicology 101 In this episode Alyssa Essman and Sarah Lancaster sit down with Washington State University toxicologist Dr. Allan Felsot for a crash course in Toxicology 101. Dr. Felsot breaks down how the EPA evaluates pesticide safety, explains the difference between hazard and risk, and clarifies common misconceptions about chemical exposure, tolerance, and persistence. The conversation also touches on glyphosate, PFAS-related concerns, and why effective science communication—and early education—matter for helping the public understand pesticide technology.

In this episode, Alyssa Essman and Sarah Lancaster talk with Washington State University toxicologist Dr. Allan Felsot for a Toxicology 101 crash course.
