Dieldrin was produced as an insecticide from the 1950s to 1970, and was widely used as pesticide for corn, cotton, and citrus crops. Dieldrin was also used for mothproofing clothes and carpets. In 1970, the US Department of Agriculture canceled all uses of dieldrin. However, the US Environmental Protection Agency (USEPA) approved the use of.

Originally developed in the 1940s as an alternative to DDT, dieldrin proved to be a highly effective insecticide and was very widely used during the 1950s to early 1970s. Endrin is a stereoisomer of dieldrin. However, it is an extremely persistent organic pollutant; it does not easily break down

Dieldrin is a organochlorine pesticide that is now banned in most of the world. It is a white powder with a mild chemical odor. Between the 1950s and 1970, dieldrin was used widely for crops like corn and cotton in the United States. It was banned by the U.S. EPA in 1974 for all uses except termite control. In 1987, the EPA banned all uses. Another pesticide, aldrin, is similar to dieldr Dieldrin, chlorine-containing organic compound used as an insecticide; se

dieldrin (Davis and Fitzhugh, 1962). Ten ppm dieldrin was administered orally to 218 male and female C3HeB/Fe mice for 2 years. The study was compromised by the poor survival rate, lack of detailed pathology, loss of a large percentage of the animals to the study, and failure to treat the data for males and females separately Dieldrin can then be directly oxidized by cytochrome oxidases, which forms 9-hydroxydieldrin. An alternative for oxidation involves the opening of the epoxied ring by epoxied hydrases, which forms the product 6,7-trans-dihydroxydihydroaldrin Dieldrin ist der Haupt metabolit und aktive Wirkstoff von Aldrin. Dieldrin ist praktisch unlöslich in Wasser. Es haftet an Bodenpartikel und kann durch Ausschwemmung von Böden in Gewässer gelangen. In der Atmosphäre kann es an Staubpartikel gebunden über weite Entfernungen transportiert werden. Dieldrin ist toxisch für Tiere und Menschen The Dieldrin Contamination Issue Until 1987, the organochlorine, dieldrin was used by potato farmers in several areas of southern Victoria to control insect pests such as wire worm (Gonocephalum pterohelaeus) and white fringed weevil (Graphognathus leucoloma). The traditional management system for these farmers is to rotate paddocks between potato cropping and sown grass/clover pasture.

Dieldrin released into the soil persists for an extremely long time (more than seven years). However, it is lost from the soil very rapidly in tropical areas, with up to 90 percent disappearing within one month.

In vivo studies on absorption following inhalation exposure of animals to aldrin/dieldrin were not located. In an in vitro study using isolated perfused rabbit lungs, aldrin (0.25, 0.50, 1.0, 1.5, 2.0, 2.5, and 3.0 μmol) was taken up by simple diffusion and then metabolized at a slower rate to dieldrin in the lung. Dieldrin was detected 3 minutes after initiation of the experiment San Diego Air and Space Museum's Library and Archives.

Dieldrin (T3D0017) Dieldrin is a chlorinated hydrocarbon used as an insecticide, either by itself or as a component of the closely related insectide aldrin. As dieldrin is neurotoxin and tends to bioaccumulate, its use is now banned in most parts of the world. ( 5) Dieldrin is a chlorinated hydrocarbon originally produced in 1948 by J. Hyman. Cattle, and other stock (including free-range pigs, poultry and ratites), can accumulate dieldrin and DDT residues in their body fat, mainly through ingestion of soil as they graze on affected land. These chemicals are absorbed from the gastrointestinal tract and accumulate in body fat of cattle or other grazing stock, as well as in eggs in free-ranging poultry

Dieldrin is closely related to aldrin which itself breaks down to form dieldrin. Aldrin is not toxic to insects, it is oxidised in the insect to form dieldrin which is the active compound. Both dieldrin and aldrin are named after the Diels-Alder reaction which is used for form aldrin from a mixture of cyclopentadiene and hexachlorocyclopentadiene The inclusion of acid-processed clays resulted in the highest reduction of dieldrin toxicity (70%) in the hydra. Further work indicated that both CM and APM can significantly reduce the bioavailability of dieldrin from soil (p ≤ 0.01)
Das Dieldrin wird in der Leber zu einer hydrophilen Verbindung weiter oxidiert, die nach Glucuronidierung mit dem Urin ausgeschieden werden kann. Allerdings geht die Umwandlung des Dieldrin nur langsam voran, es reichert sich im Fettgewebe an. Die Halbwertszeit zur Elimination von Dieldrin beim Menschen wurde auf etwa ein Jahr geschätzt Dieldrin altered proteins associated with cancer, apoptosis, transcription and development. Wnt-2b was reduced 3-fold and immunolocalized to Leydig and Sertoli cells.
