What is ddt meaning?

DDT (Dichlorodiphenyltrichloroethane) is a synthetic insecticide widely used during the 1940s to the 1970s to control malaria, typhus, and other insect-borne diseases. However, due to its harmful effects on the environment and human health, DDT was banned in several countries including the USA in 1972. DDT is persistent in the environment and can travel long distances through air and water. It accumulates in the food chain, causing damage to birds, animals, and humans by disrupting their hormonal balance, immune system, and neurological function. While DDT is still used in some countries to control malaria, its use is controversial and limited due to its adverse effects.
