DDE is a primary metabolite of which pesticide?

DDE is a primary metabolite of which pesticide?

• A. Carbaryl
• B. Glyphosate
• C. DDT
• D. Atrazine

Answer: (C)

DDE forms when DDT is metabolized in organisms and the environment. DDT undergoes dehydrochlorination to become DDE, a stable, highly lipophilic metabolite that persists in fatty tissues and in the environment. Among the pesticides listed, the one that yields DDE as its primary metabolite is DDT, whereas the others break down into different compounds (carbaryl to naphthol derivatives, glyphosate to AMPA, atrazine to deisopropyl/desethyl atrazine). That linkage makes DDT the correct association.
