It is one of the clearest examples we have of how a single toxic exposure can echo through a lifetime. The culprit wasn’t the orange barrels. It was the dioxin inside them — TCDD — a chemical now classified as a known human carcinogen by every major scientific body that studies cancer. Dioxin doesn’t rush. It lingers.
