DDT

DDT (dichlorodiphenyltrichloroethane) is a colorless, crystalline, tasteless and almost odorless organochlorine known for its insecticidal properties and environmental impacts. DDT has been formulated in multiple forms, including solutions in xylene or petroleum distillates, emulsifiable concentrates, water- wettable powders, granules, aerosols, smoke candles and charges for vaporizers and lotions.

First synthesized in 1874, DDT's insecticidal action was discovered by the Swiss chemist Paul Hermann Müller in 1939. It was used in the second half of World War II to control malaria and typhus among civilians and troops. After the war, DDT was also used as an agricultural insecticide and its production and use duly increased. Müller was awarded the Nobel Prize in Physiology or Medicine "for his discovery of the high efficiency of DDT as a contact poison against several arthropods" in 1948.

In 1962, Rachel Carson's book Silent Spring was published. It cataloged the environmental impacts of widespread DDT spraying in the United States and questioned the logic of releasing large amounts of potentially dangerous chemicals into the environment without understanding their effects on the environment or human health. The book claimed that DDT and other pesticides had been shown to cause cancer and that their agricultural use was a threat to wildlife, particularly birds. Its publication was a seminal event for the environmental movement and resulted in a large public outcry that eventually led, in 1972, to a ban on DDT's agricultural use in the United States. A worldwide ban on agricultural use was formalized under the Stockholm Convention on Persistent Organic Pollutants, but its limited and still-controversial use in disease vector control continues, because of its effectiveness in reducing malarial infections, balanced by environmental and other health concerns.

Along with the passage of the Endangered Species Act, the United States ban on DDT is cited by scientists as a major factor in the comeback of the bald eagle (the national bird of the United States) and the peregrine falcon from near-extinction in the contiguous United States.

DDT (band)

DDT (or ДДТ in Cyrillic) is a popular Russian rock band founded by its lead singer and the only remaining original member, Yuri Shevchuk (Юрий Шевчук), in Ufa ( Bashkir ASSR, RSFSR) in 1980. Named after the pesticide DDT, they are one of the better known and most prolific Russian bands of the late 20th and early 21st centuries.

DDT (disambiguation)

DDT may refer to:

DDT (professional wrestling)

In professional wrestling a DDT is any move in which the wrestler has the opponent in a front facelock/inverted headlock, and falls down or backwards to drive the opponent's head into the mat. 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. Although widely credited as an invention of Jake Roberts, who gave the DDT its famous name, the earliest known practitioner of the move was Mexican wrestler Black Gordman, who frequently performed it during the 1970s. Rumors abound as to what the letters DDT supposedly stood for, including Drape Drop Takedown, Drop Dead Twice, Demonic Death Trap, Drop Down Town, Death Drop Technique and Damien's Dinner Time or Damien's Death Touch (the latter two named after Jake's pet python Damien). When asked what DDT meant, Jake once famously replied "The End." The abbreviation itself originally came from the chemical dichloro-diphenyl-trichloroethane, a notorious pesticide, as stated during shoot interviews and Jake's Pick Your Poison DVD. Many think that the term DDT was applied because the chemical DDT is a hazardous chemical buried in the ground which potentially causes brain damage.

DDT (gene)

D-dopachrome decarboxylase is an enzyme that in humans is encoded by the DDT gene.

D-dopachrome tautomerase converts D-dopachrome into 5,6-dihydroxyindole. The DDT gene is related to the macrophage migration inhibitory factor (MIF) in terms of sequence, enzyme activity, and gene structure. DDT and MIF are closely linked on chromosome 22.

DDT (zine)

DDT (sometimes published as Dada Tennis, or Da-da Tennis) was a magazine of bizarre free-surrealist writings and graphics, which were chiefly created by its editor, Bill Paulauskas, who died in 2006. It was published by Paulauskas' Dream State Press, which he operated in New York City.

Its publication history is long and complex; it first grew out of freewheeling interactions on a computer bulletin-board site ( BBS) called The Enterprise, in the late 1980s, then moved to Paulauskas' own Dreamworld BBS, before starting to appear in print form.

The magazine continued to exist in print form, on an erratic schedule; it also (for a few years in the early 1990s) was a multimedia computer disc designed for use in the Amiga computer. During its computer-disc phase the magazine was sometimes co-edited by the novelists James Chapman and Randie Lipkin, who were also contributors. Some of the work done at this time was later adapted theatrically by the DADAnewyork theatre troupe founded by the late John W. Wilson (an original Joffrey Ballet member and Dada scholar); these pieces were performed internationally to considerable confusion.

Along with text and graphics, Paulauskas also created an audio adjunct to his zine, Krelltone Records, a project of his Lost in Wallpaper Collective, which featured recordings of Paulauskas' strange poetry and found sounds from throughout all recorded history, collaged together to hilarious and disturbing effect. He was also a filmmaker, and the final issue of DDT (published in 2005) appeared on DVD.
