What is what does ddt stand for?

DDT stands for dichlorodiphenyltrichloroethane, which is a colorless, odorless, and tasteless insecticide that was widely used in the 20th century to control various pests, including mosquitoes that carry malaria, typhus, and other diseases. However, it was found to have harmful effects on the environment and animals, particularly birds, and has been banned in many countries since the 1970s.
