  ATSDR - ToxFAQs™: DDT, DDE, and DDD
DDT (dichlorodiphenyltrichloroethane) is a pesticide once widely used to control insects in agriculture and insects that carry diseases such as malaria.
DDT entered the environment when it was used as a pesticide; it still enters the environment due to current use in other countries.
DDT, DDE, and DDD in air are rapidly broken down by sunlight.

  DDT (professional wrestling) - Wikipedia, the free encyclopedia
The classic DDT is performed by putting the opponent in a front facelock and falling backwards so that the opponent is forced to dive forward onto his or her head.
Many think the term DDT was appropriated because the chemical DDT is something "bad" that is buried in the ground and causes extreme danger when there; similarly, a DDT is bad in that it buries an opponent's head into the mat, causing extreme danger to the brain and spinal cord.
Implant DDT refers to variations of the DDT where the opponent is driven to the mat face first, as in a faceplant, and not on to their heads.

 DDT (PIM 127)
DDT and some of the breakdown products of DDT, principally DDE, are highly persistent in soil, sediment and biota as they are relatively resistant to breakdown by the enzymes and higher organisms found in the soil (WHO, 1979).
DDT and its metabolites are highly toxic to fish and, besides their lethal effects, they affect development, behaviour and biochemical processes.
DDT is relatively non volatile and, although inhalation of spray drift may occur during occupational use, respiratory exposure is a less significant route.

 DDT
DDT the first of the chlorinated organic insecticides, was originally prepared in 1873, but it was not until 1939 that Paul Muller of Geigy Pharmaceutical in Switzerland discovered the effectiveness of DDT as an insecticide he was awarded the Nobel Prize in medicine and physiology in 1948 for this discovery).
DDT seemed to be the ideal insecticideit is cheap and of relatively low toxicity to mammals (oral LD50 is 300 to 500 mg/kg).
The buildup of DDT in natural waters is a reverisble process: the EPA reported a 90% reduction of DDT in Lake Michigan fish by 1978 as a result of the ban.

 NRDC: The Story of Silent Spring
Thirteen years later, in 1958, Carson's interest in writing about the dangers of DDT was rekindled when she received a letter from a friend in Massachusetts bemoaning the large bird kills which had occured on Cape Cod as the result of DDT sprayings.
The use of DDT had proliferated greatly since 1945 and Carson again tried, unsuccessfully, to interest a magazine in assigning her the story of its less desirable effects.
By 1958 Carson was a best-selling author, and the fact that she could not obtain a magazine assignment to write about DDT is indicative of how heretical and controversial her views on the subject must have seemed.

 WHO | WHO gives indoor use of DDT a clean bill of health for controlling malaria
WHO actively promoted indoor residual spraying for malaria control until the early 1980s when increased health and environmental concerns surrounding DDT caused the organization to stop promoting its use and to focus instead on other means of prevention.
In the past, India was able to use DDT effectively in indoor residual spraying to cut dramatically the number of malaria cases and fatalities.
South Africa has again re-introduced DDT for indoor residual spraying to keep malaria case and fatality numbers at all-time low levels and move towards malaria elimination.

 WWF - DetoX campaign glossary
DDT - An obsolete organo-chlorine insecticide, classified as a persistent organic polllutant (POP).

 DDT > Toxics > Sierra Club
DDT and its breakdown chemicals are synthetic, persistent global pollutants that have been found in residents of remote areas where DDT has never been used, including Inuit and other Arctic peoples.
Under closely controlled conditions and as part of a broader, integrated response, Sierra Club agrees that DDT should only be used in accordance with limiting provisions agreed to by more than 150 nations in the Stockholm Convention.
Sierra Club believes that DDT should be considered as the option of last resort only, when all feasible non-toxic and less toxic alternatives have been tried and proven ineffective.

 Documentation for Immediately Dangerous to Life or Health Concentrations (IDLHs) - 50293
TWA; NIOSH considers DDT to be a potential occupational carcinogen as defined by the OSHA carcinogen policy [29 CFR 1990].
AIHA [1959] reported that the concentration immediately hazardous to life is "probably unobtainable," and that DDT has a low order of acute toxicity by inhalation.
However, for some particulate substances for which no evidence of an IDLH exists, the determination of allowable respiratory protection based on protection factors may result in the assignment of respirators for concentrations that are not likely to be encountered in the occupational environment.
