DDT

noun \ˌdē-(ˌ)dē-ˈtē\   (Medical Dictionary)

DDT

noun    (Concise Encyclopedia)

Synthetic insecticide belonging to the family of organic halogens. In 1939 its toxicity to a wide variety of insects was discovered (by Paul Hermann Müller, who was awarded a Nobel Prize for his work) and effectively used against many disease vectors. By the 1960s, many species of insects had developed populations resistant to DDT; meanwhile, this highly stable compound was accumulating along the food chain and having toxic effects on various birds and fishes. During the 1960s it and similar chemicals were found to have severely reduced the populations of certain birds, including the bald eagle.
