Identification
Common NameP,P'-DDE
ClassSmall Molecule
DescriptionDDE, P,P'- is an isomer of dichlorodiphenyldichloroethylene, an organochlorine insecticide. It is one of the components of commercial mixtures of DDT. DDT was once a widely used pesticide, but today its agricultural use has been banned worldwide due to its toxicity and tendency to bioaccumulate. However, it still has limited use in disease vector control. (1)

Toxicity Profile
Route of ExposureOral (2)
Mechanism of ToxicityDDE toxicity occurs via at least four mechanisms, possibly all functioning simultaneously. DDE reduces potassium transport across the membrane. DDE inhibits the inactivation of voltaged-gated sodium channels. The channels activate (open) normally but are inactivated (closed) slowly, thus interfering with the active transport of sodium out of the nerve axon during repolarization and resulting in a state of hyperexcitability. DDE inhibits neuronal adenosine triphosphatases (ATPases), particularly Na+K+-ATPase, and Ca2+-ATPase which play vital roles in neuronal repolarization. DDE also inhibits the ability of calmodulin, a calcium mediator in nerves, to transport calcium ions that are essential for the release of neurotransmitters. All these inhibited functions reduce the rate of depolarization and increase the sensitivity of neurons to small stimuli that would not elicit a response in a fully depolarized neuron. DDE is also believed to adversely affect the reproductive system by mimicking endogenous hormones and binding to the estrogen and adrogen receptors. (6, 2)
MetabolismDDE is absorbed in the stomach and intestine, after which it enters the lymphatic system and is carried throughout the body and incorporated into fatty tissues. Metabolism of DDE occurs mainly via cytochrome P-450 enzymes in the liver and kidney. Its metabolites, mainly DDA (bis(p-chlorophenyl) acetic acid), are excreted in the urine. (2)
Toxicity ValuesNot Available
Lethal DoseNot Available
Carcinogenicity (IARC Classification)Not directly listed by IARC, but carcinogenicity studies of this DDT metabolite are discussed in connection with DDT (5).
Uses/SourcesDDE is found in DDT, which is used as a pesticide and in disease vector control. (1)
Minimum Risk LevelNot Available
Health EffectsExposure to DDT causes loss of weight and anorexia. DDT poisoning affects CNS function in humans, but pathologic changes are observed in the liver and reproductive organs. Hypertrophy of hepatocytes and subcellular organelles such as mitochondria, proliferation of smooth endoplasmic reticulum, centrolobular necrosis after exposure to high concentrations, and an increase in the incidence of hepatic tumors have been noted. (6)
SymptomsAcute signs of DDT poisoning include paresthesia after oral ingestion. Studies have shown that a mammal poisoned with DDT-type agents displays periodic persistent tremoring and/or convulsive seizures that are suggestive of repetitive discharges in neurons. These repetitive tremors and seizures can be initiated by tactile and auditory stimuli. (6)
TreatmentTreatment of DDT exposure should be primarily directed towards decontamination and supportive care, as there is no specific antidote. The use of gastric lavage and activated charcoal for large ingestions may be effective. (4)
