In 1976, thousands of inhabitants of Seveso, Italy were exposed to TCDD after an accidental release of several kilograms of TCDD from a pressure tank.
The Poison That Fell From the Sky (1977) is about dioxin poisoning following a chemical plant disaster in Seveso, Italy.
Subsequent research on the effects of dioxin on humans and other mammals has led some experts to question whether the evacuation of the town was necessary, sometimes citing the example of Seveso, Italy, the site of a disaster in 1976 that exposed residents to larger levels of dioxin than those of Times Beach and whose subsequent cleanup allowed the city to continue to exist.
It is also known as the Seveso II Directive, after the Seveso disaster.
