What is "dichlorodiphenyldichloroethylene"

n. (context organic chemistry English) A metabolite of DDT.

Dichlorodiphenyldichloroethylene (DDE) is a chemical compound formed by the loss of hydrogen chloride ( dehydrohalogenation) from DDT, of which it is one of the more common breakdown products. Due to DDT’s massive prevalence in society and agriculture during the mid 20th century, DDT and DDE are still widely seen in animal tissue samples. DDE is particularly dangerous because it is fat-soluble like other organochlorines, thus it is rarely excreted from the body and concentrations tend to increase throughout life. The major exception is the excretion of DDE in breast milk, which delivers a substantial portion of the mother's DDE burden to the young animal or child. Along with accumulation over an organism's life, this stability leads to bioaccumulation in the environment which amplifies DDE’s negative effects.
