CHEMICAL STRUCTURE OF DDT


DDT (from its trivial name, dichlorodiphenyltrichloroethane) is one of the most well-known synthetic pesticides. It is a chemical with a long, unique, and controversial . 1962, American biologist Rachel Carson wrote Silent Spring. The book cataloged the environmental impacts of indiscriminate DDT use in the US and questioned the logic of releasing large amounts of chemicals into the environment without fully understanding their effects on the environment or human health. The book suggested that DDT and other pesticides cause cancer and that their agricultural use was a threat to wildlife, particularly birds. Its publication was a signature event in the birth of the environmental movement. It produced a large public outcry that led to a 1972 ban in the US. DDT was subsequently banned for agricultural use worldwide under the Stockholm Convention, but limited, controversial use in disease vector control continues.
