Dieldrin is an organochloride originally produced in 1948 as an insecticide. Dieldrin is closely related to aldrin, which reacts further to form dieldrin. Aldrin is not toxic to insects; it is oxidized in the insect to form dieldrin which is the active compound. Formerly used as an insecticide; product of oxidized aldrin (former insecticide). All uses except termite control banned in US in 1974; all uses banned in US in 1987. | Regenesis. Accessed 13 October 2020 | Link |
Dieldrin (a product containing 85% of 1,2,3,4,10,10-hexachloro-6,7-epoxy-1,4,4a,5,6,7,8,8a-octahydro-exo-1,4-endo-5,8- dimethanonaphthalene, HEOD) resulted from an attempt to make aldrin less volatile. Because of its lower volatility, dieldrin was used on crops and their foliage, in addition to soil and seed dressing applications, both at considerably lower rates than those of DDT. Dieldrin was also very effective against ectoparasites of cattle and sheep, as well as for mothproofing fabrics. In Britain the extensive use of aldrin and dieldrin started in 1956. By the early 1960s, mortalities of birds associated with seeds treated with aldrin or dieldrin were observed and confirmed in laboratory experiments. In addition, dieldrin was detected in human tissues. As a result of these observations and of the potential carcinogenicity of dieldrin, concerns were raised about the safety of aldrin and dieldrin, and their use was gradually limited. | Zitko. 2002.

Aldrin and dieldrin (a metabolite of aldrin and a marketed pesticide) are the common names of two chemically related insecticides that were widely used from the 1950s to the early 1970s. Aldrin was used as an insecticide in soil to control invertebrates, such as worms, beetles, and termites, and has been widely used to protect crops such as corn and potatoes, and was effective for protecting wooden structures from termites. Aldrin is readily metabolized to dieldrin in both animals and plants, and therefore, aldrin residues are rarely detected in animals and if so only in small amounts. Residues of dieldrin exist in the environment and in human tissues, but levels have been declining during the last 30 years. Aldrin and dieldrin have comparable toxicity and have more than one mechanism of toxicity. | Berntssen et al., 2012. Contamination of finfish with persistent organic pollutants and metals | Link |
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 1987, dieldrin was banned for all uses, and the manufacturer voluntarily canceled the registration for use in controlling termites. | Honeycutt and Shirley. 2014. Dieldrin | Link |
Dieldrin is an organochloride originally produced in 1948 by J. Hyman & Co, Denver, as an insecticide. Dieldrin is closely related to aldrin, which reacts further to form dieldrin. Aldrin is not toxic to insects; it is oxidized 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 to form aldrin from a mixture of norbornadiene and hexachlorocyclopentadiene. | Wikipedia.
