• 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.
