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. Dieldrin is an organochlorine pesticide (OCP) that was used extensively in agriculture throughout the United States until a ban on its use in 1987. Pogell, B. M., Krisman, C. R.: Enzymic hydrolysis of uridine diphosphate glucuronate in rat skin. OCPs, including dieldrin, are highly resistant to degradation in the environment, extremely bio-accumulative in agricultural and food products, and persist in … Effect of dieldrin on auditory detection behavior and central auditory mechanisms in sheep Dennis Dean Elsberry Iowa State University Follow this and additional works at: ... effects upon other aspects of the environment which are not directly related to food production. It is a white powder with a "mild chemical odor." Because of concerns about damage to the environment and potentially to human health, the US Environmental Protection Agency (EPA) banned all uses of dieldrin in 1974, except to control termites. Aldrin and dieldrin were mainly used as insecticides. Sustained induction of microsomal enzymes with absence of liver damage on feeding phenobarbitone or butylated hydroxytoluene. However, the extent of induction was less pronounced than that caused by dieldrin. Research concerning the effects of chronic, low-dose dieldrin is still being conducted (Sava et al., 2007). This substance may be hazardous to the environment. 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. Beitr. This chemical is known to be a potential carcinogen and suspected endocrine disruptor that can increase the risk of Parkinson’s disease and cause organochlorine compound poisoning. A., Wooder, M. F.: Studies on the interactions of dieldrin with mammalian liver cells at the subcellular level. Environ. Some animals maintained on semi-synthetic diet and filterpaper bedding also developed nodular liver lesions, which suggests the presence of a pre-existing oncogenic factor or susceptibility in this strain of mouse. ), p. 788–792.

Long-term oral toxicity studies in mice. Ferguson, H. C: The effect of red chedar chip bedding on hexobarbital and pentobarbital sleeping time. Based on its chemical properties, it is not expected to leach to groundwater. Toxicol. Cancer Res. Dieldrin is part of the "drin" group of pesticides and therefore has similar properties to other members of the group such as Endrin, Aldrin and Isodrin. Cite as. In contrast to the effects of dieldrin, conventional diet and sawdust bedding did not cause any significant induction of secondary drug metabolising enzyme systems, e.g. J. Bergmeyer, H. H. Because aldrin and dieldrin last for a long time in the environment, the chemicals are still in the environment from when they were used as insecticides for crops and to kill termites before 1987. Abstract. Cancer Inst. Dieldrin is highly toxic to aquatic organisms and many other forms of wildlife and can accumulate in the environment, particularly in the fat of animals. Dieldrin is a organochlorine pesticide that is now banned in most of the world. For more information about the effects of dieldrin on the environment and human health contact the EPA on 1300 372 842. From the 1950s until 1970, dieldrin was used widely on corn and cotton. Dieldrin is a UK Red List pollutant because of concern about its harmful impacts on the environment and human health. The insecticide, dieldrin, is known to have pleiotropic toxic effects in animals, inhibited gap junctional communication. Cancer Inst. The substance identifiers displayed in the InfoCard are the best available substance name, EC number, CAS number and/or the … J. Natl. European Directives regulating levels of Dieldrin include that concerned with the marketing and use of certain dangerous chemicals (79/117/EEC) and that concerned with pollution of the aquatic environment (76/464/EEC). Gann, Nagasaki, H., Tomii, S., Mega, T., Marugami, M., Ito, N.: Carcinogenicity of benzenehexachloride (BHC). Their report showed that the lethal oral dose for aldrin and dieldrin for all species was in the range of 20-70 mg/kg body weight. Its use is now banned in the EU. It was banned by the U.S. EPA in 1974 for all uses except termite control. Page 1 MICHIGAN DEPARTMENT OF NATURAL RESOURCES Research and Development Report No. View PDF version here. Pharmacol. 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. However, exposure to dieldrin at normal background levels is unlikely to have any adverse effect on human health. Tomatis, L., Turusov, V., Charles, R.

R., Day, N.: The effects of long-term feeding of DDT to BALB/C mice. Vessell, E. S.: Induction of drug-metabolising enzymes in liver microsomes of mice and rats by softwood bedding. The effects of conventional diet and softwood bedding on hepatocellular pathways for the metabolism of xenobiotics and also upon the incidence of liver tumours in dieldrin-treated and non-dieldrin-treated mice were studied using animals maintained on semi-synthetic diet and filterpaper bedding as controls. Both benign and malignant liver tumours were found in these animals; the latter type of lesion showing evidence of lung metastasis. Chemical inhibition of gap junctional communication could be a possible mechanism explain their tumor promoting and neurotoxic effects. phenobarbitone, Tomatis, L., Turusov, V., Day, N., Charles, R. T.: The effects of long-term exposure to DDT on CF1-mice. Dieldrin is classed as a "persistent organic pollutant" (POP). Davis, L. J., Fitzhugh, O. G.: Tumourigenic potential of aldrin and dieldrin for mice. Dieldrin is stored in fatty tissues such as breast tissue. Schulte-Hermann, R.: Induction of liver growth by xenobiotic compounds and other stimuli. Studies of endrin, aldrin, and dieldrin are limited, but the immunologic effects reported for these chemicals in laboratory studies appear to involve macrophage processing of antigen. J. Miami, Florida, 1973. Dieldrin is also listed as a candidate substance under the OSPAR Convention which protects the marine environment of the north-east Atlantic Ocean. It is concluded that dieldrin acts by facilitating the expression of pre-existing oncogenic potential in mouse liver, probably by inducing hyperplasia in this organ. The lowest exposure level having biological effects was with rhesus monkeys where feeding 5 parts per million (ppm) dieldrin for 1 year resulted in death. Organochlorine pesticides (OCPs) including dieldrin and lindane remain ubiquitous in the environment and food supply due to their resistance to degradation and bioaccumulation along the food chain. Dieldrin evaporates easily. There are not thought to be any natural sources of Dieldrin to the environment.
