1 rich Libsyn https://www.libsyn.com 90 600 Part 4 of the Forever Chemicals Detox 101 series We’ve all heard the principle that “the dose makes the poison.” But when it comes to some environmental exposures, the relationship between dose and biological effect can be more complicated than that phrase suggests. In this episode, I explore what researchers have learned about low-dose exposures to chemicals such as PFAS and endocrine-disrupting chemicals—and why timing, susceptibility, and mixtures can matter alongside dose. We look especially at endocrine disruptors, which can interfere with hormone signaling at very low concentrations, and at why scientists continue to debate how conventional assumptions about toxicology apply to chemicals that interact with our hormonal systems. In this episode: Why “the dose makes the poison” doesn’t tell the whole story What scientists mean by low-dose effects Why periods such as pregnancy, infancy, puberty, and other sensitive windows of development can matter How exposure to multiple chemicals at once complicates risk assessment Why reducing everyday exposures can still be worthwhile even when science can’t tell us exactly how much individual reductions will change our health The goal isn’t to fear every small exposure. It’s to understand why “a little” doesn’t automatically mean “irrelevant”—and where practical reductions may make sense. This is Part 4 of my Forever Chemicals Detox 101 series.
