Legacy Pesticides

Legacy pesticides (including DDT and chlordane) are chemicals that were once used in the US but are now canceled or banned because of health risks to humans, animals, or the environment. The legacy these pesticides leave behind is their long-lived persistence in the environment. Once released, they may take many years to degrade.

Several of these pesticides have been found to accumulate in the tissue of people and animals. Some breakdown products of these pesticides may be more persistent or toxic than the original.
