DIOXIN IN THE USA
• The USA has had several TCDD scares.
• Times Beach, Missouri (1971) : a waste
contractor mixed waste sludge from a
2,4,5-T factory with waste oil and sprayed
it onto roads, horse tracks, yards to control
dust. The sludge contained 30kg of dioxin.
The town was abandoned.
• Love Canal, Niagara (1978) : a housing
estate was built on a chemical waste dump
containing 60kg of dioxin. Evacuations were carried out as this is enough TCDD to kill 760 million people.
