DDT (structural model)

1,1,1-trichloro-2,2-bis (p-chlorophenyl) ethane is the designation of the pure form of p,p′-DDT. The commercial pesticide commonly known as DDT is really a mixture of isomers, including p,p′-DDT, o,p-DDT and a meta form of DDT; however, the general metabolic pathways DDT follows through living systems eventually lead to DDE and it is DDE that is the environmental toxicant which has become a global concern because of its persistence, biomagnification through trophic chains and food webs and its unintended effects on non-target organisms.
