TCDD

In 1969, evidence linked a chemical in Agent Orange, 2,4,5-T, to birth defects and stillbirths in mice because it contained TCDD, a particularly harmful dioxin.

Boeing paid $25,750 for the elevated levels of TCDD, a potent cancer-causing dioxin.

Agent Orange contained TCDD, the world’s most toxic dioxin, which has since been linked to at least 17 illnesses and cancers.

Agent Orange contains a byproduct called dioxin TCDD, which can remain in the environment for decades or even centuries.

The most common and dangerous dioxin - TCDD, an ingredient in the Vietnam War-era defoliant Agent Orange - is linked to lung cancer and non-Hodgkin’s lymphoma.
