Description and Uses

DDT is a polychlorinated persistent chemical that exists as a solid under normal conditions.Even though DDT seemed to be a cheap and effective pesticide, enough was known in its early development to raise concerns. DDT is a persistent chemical that lasts a long time in the environment. DDT is fat-soluble and not readily metabolized by higher organisms. Th is meant that DDT accumulated in the fat tissues of higher organisms.

The primary use of DDT is as a vector control for eradication of malaria-bearing mosquitoes. Less persistent insecticides have replaced DDT for control of insects on crops and in forests.
