DDT exposure can occur by eating, breathing, or touching products contaminated with DDT. DDT can convert into DDE, and both persist in body and environment. In the body, DDT converts into several breakdown products called metabolites, including the metabolite dichlorodiphenyldichloroethene (DDE).
What did the old mosquito trucks spray? Waging war against mosquitoes with DDT In the late 1940s, and into the 1950s and 1960s, trucks would drive through the streets spraying the pesticide, leaving a thick fog behind.

Why did they stop spraying kids with DDT? In 1972, EPA issued a cancellation order for DDT based on its adverse environmental effects, such as those to wildlife, as well as its potential human health risks. Since then, studies have continued, and a relationship between DDT exposure and reproductive effects in humans is suspected, based on studies in animals.
How does DDT enter the human body? – Related Questions
Did they spray DDT on people?
