In plants and mosquito larvae DDT is converted to DDD.
Dichlorodiphenyltrichloroethane, commonly known as DDT, is a colorless, tasteless, and almost odorless crystalline chemical compound, an organochloride.
DDE and DDD form when DDT breaks down. These chemicals can evaporate into the air from water and moist soil and may then be carried to locations very far from the source. They can be removed from the air by rain and snow or be broken down by sunlight.
