... The relationship between the structures of cyclodiene type insecticides & the interaction with ... picrotoxinin receptor /have been investigated/. It was ... found that their competitive binding abilities to the picrotoxinin receptor of the brain of the American cockroach are well related to their insecticidal properties. ... The most active cmpd were kepone, gamma-BHC, photodieldrin, oxychlordane, & toxaphene. ... In summary, the ... evidence indicates that cyclodiene-type insecticides owe their neuroexicitatory actions to their abilities to interact with picrotoxinin receptor in nervous system. ... The end result of the interaction is the inhibition of Cl- uptake by the neurons & perhaps by muscles, which results in an uncontrolled excitation in those cells that are normally supplied with gamma-aminobutyric acid.
There are two kinds of gamma-aminobutyric acid (GABA) receptors: GABAA is the major inhibitory receptor of vertebrate brain and the one that operates a Cl- channel, and the GABAB receptor, which is proposed to regulate cAMP production. ... It is suggested that the GABAA receptor is the primary target for the action of toxaphene and cyclodiene insecticides.
In vivo effect of toxaphene on calcium pump activity in rat brain P2 fraction was studied. Male Sprague-Dawley rats (200-250 g) were dosed with toxaphene at 0, 25, 50, and 100 mg/kg/day for 3 days and sacrificed 24 hr after last dose. Ca2+-ATPase activity and (45)Ca2+ uptake were determined in brain P2 fraction. Toxaphene decreased both Ca2+-ATPase activity and (45)Ca2+ uptake, and the reduction was dose dependent. Both substrate and Ca2+ activation kinetics of Ca2+-ATPase indicated noncompetitive type of inhibition, as evidence by decreased catalytic velocity but not enzyme-substrate affinity. The decreased Ca2+-ATPase activity and (45)Ca2+ uptake were restored to normal level by exogenously added calmodulin, which increased both velocity and affinity. The inhibition of Ca2+-ATPase activity and (45)Ca2+ uptake and restoration by calmodulin suggests that toxaphene may impair active calcium transport mechanisms by decreasing levels of calmodulin.
The toxicity to mice of intraperitoneally administered polychlorocycloalkane (PCCA) insecticides is generally correlated with their potency as in vitro inhibitors of the brain specific (35)S t-butylbicyclophosphorothionate binding site with correction for metabolic activation and detoxification. ... Radioligand binding assays involved brain P2 membranes washed three times with 1 mM EDTA to remove endogenous gamma-aminobutyric acid (GABA) or other modulator(s) which otherwise serves as a noncompetitive inhibitor of (35)S t-butylbicyclophosphorothionate binding at the gamma-aminobutyric acid regulated chloride ionophore. Examination of technical toxaphene, toxaphene toxicant A, revealed 62 + or - 4% binding site inhibition 30 min after their LD50 doses with 32 + or - 3% inhibition at one-half and 6 + or - 3% inhibition at one-quarter of their LD50 doses. The correlation between binding site inhibition and convulsant action is also evident in dose and time dependency studies with endosulfan sulfate. The brain P2 membranes of treated mice contain the parent compound with each of the polychlorocycloalkane plus activation products of some of the cyclodienes, ie endosulfan sulfate from alpha- and beta-endosulfan and 12-ketoendrin from isodrin and endrin. The finding that the brains of treated mice contain sufficient polychlorocycloalkane or its activation products to achieve a magnitude of (35)S t-butylbicyclophosphorothiate binding site inhibition correlated with the severity of the poisoning signs supports the hypothesis that the acute toxicity of polychlorocyloalkane insecticides to mammals is due to disruption of the gamma-aminobutyric acid regulated chloride ionophore.

Toxaphene was one of the most heavily used pesticides in the United States in the 1970s and early 1980s. It was used primarily to control insect pests on cotton and other crops in the southern United States. Other uses included controlling insect pests on livestock and killing unwanted fish in lakes. Toxaphene was banned for all registered uses by 1990. Toxaphene is made by reacting chlorine gas with a substance called camphene. The resulting product (toxaphene) is a mixture of hundreds of different chlorinated camphenes and related chemicals.
Toxaphene was a widely used pesticide on cotton, other crops, and in livestock and poultry. In 1982, most of its uses were cancelled and in 1990, all uses were cancelled in the United States. The major effect of toxaphene is central nervous system (CNS) stimulation, which results in convulsive seizures. No studies are available on acute (short-term) inhalation exposure to toxaphene in humans or animals. Chronic (long- term) inhalation exposure to toxaphene in humans results in reversible respiratory toxicity, while chronic, oral exposure in animals has resulted in effects on the liver, kidney, spleen, adrenal and thyroid glands, CNS, and the immune system. Animal studies have reported an increased incidence of thyroid gland tumors and liver tumors via ingestion. EPA has classified toxaphene as a Group B2, probable human carcinogen.
In the past, fatal poisoning after ingestion was reported. Only a few cases of poisoning from occupational exposure were reported. [ACGIH]

TOXAPHENE /LEVEL/ IN HUMAN MILK HAS BEEN INSIGNIFICANT.
The concn of toxaphene in Finnish human adipose tissues was estimated to be on the level of 0.01-0.1 mg/kg, based on concns of toxaphene in Finnish human milk (at concns of 1 to 10 ppb). However, this estimate was strongly dependent on diet(1). Although toxaphene was used extensively during the 1960's in Alberta, Canada, analyses of human tissue from 50 autopsies at the University Hospital in Edmonton from 1967-68 did not reveal toxaphene(n=217)(1). These negative results could be due to a lack of selectivity and sensitivity of the method used for the analysis(1).
If the compound has been ingested, rapid gastric lavage should be performed using 5% sodium bicarbonate. For skin contact, the skin should be washed with soap and water. If the compound has entered the eyes, they should be washed with large quantities of isotonic saline or water. In serious cases, atropine and/or pralidoxime should be administered. Anti-cholinergic drugs work to counteract the effects of excess acetylcholine and reactivate AChE. Atropine can be used as an antidote in conjunction with pralidoxime or other pyridinium oximes (such as trimedoxime or obidoxime), though the use of '-oximes' has been found to be of no benefit, or possibly harmful, in at least two meta-analyses. Atropine is a muscarinic antagonist, and thus blocks the action of acetylcholine peripherally.

Acute exposure to cholinesterase inhibitors can cause a cholinergic crisis characterized by severe nausea/vomiting, salivation, sweating, bradycardia, hypotension, collapse, and convulsions. Increasing muscle weakness is a possibility and may result in death if respiratory muscles are involved. Accumulation of ACh at motor nerves causes overstimulation of nicotinic expression at the neuromuscular junction. When this occurs symptoms such as muscle weakness, fatigue, muscle cramps, fasciculation, and paralysis can be seen. When there is an accumulation of ACh at autonomic ganglia this causes overstimulation of nicotinic expression in the sympathetic system. Symptoms associated with this are hypertension, and hypoglycemia. Overstimulation of nicotinic acetylcholine receptors in the central nervous system, due to accumulation of ACh, results in anxiety, headache, convulsions, ataxia, depression of respiration and circulation, tremor, general weakness, and potentially coma. When there is expression of muscarinic overstimulation due to excess acetylcholine at muscarinic acetylcholine receptors symptoms of visual disturbances, tightness in chest, wheezing due to bronchoconstriction, increased bronchial secretions, increased salivation, lacrimation, sweating, peristalsis, and urination can occur. Certain reproductive effects in fertility, growth, and development for males and females have been linked specifically to organophosphate pesticide exposure. Most of the research on reproductive effects has been conducted on farmers working with pesticides and insecticdes in rural areas. In females menstrual cycle disturbances, longer pregnancies, spontaneous abortions, stillbirths, and some developmental effects in offspring have been linked to organophosphate pesticide exposure. Prenatal exposure has been linked to impaired fetal growth and development. Neurotoxic effects have also been linked to poisoning with OP pesticides causing four neurotoxic effects in humans: cholinergic syndrome, intermediate syndrome, organophosphate-induced delayed polyneuropathy (OPIDP), and chronic organophosphate-induced neuropsychiatric disorder (COPIND). These syndromes result after acute and chronic exposure to OP pesticides.

During a 5 study conducted from Oct 1981 to Sept 1986, 19,851 food samples were analyzed for a wide variety of pesticide residues. Toxaphene was detected in 14 food samples at an average concn level of 0.5 ppm (max 2 ppm)(1). Toxaphene was mostly detected in tomatoes at 0.1 ppm, in carrots, fresh bell peppers, potatoes, and cherry tomatoes at 0.5 ppm; in tomatillos at 1 ppm; in jalapeno peppers from 1 to 2 ppm; and in parsley at 2 ppm(1). Toxaphene was reported to be present in the total diet study conducted by the FDA in which they analyzed 14,492 samples of domestically produced and imported food from 79 countries. Toxaphene was not detected in more than 50% of the samples and when it was detected it was usually below tolerance levels(1). Less than 1% exceeded regulatory limits.
The average daily intake of toxaphene in the USA from 1971-76 was 0.003 ug/kg body weight/day(1). The percentage of composite samples testing positive for toxaphene and the daily intake in ug/kg body weight for each year was: 1971 - 0.3% (trace), 1972 - 0.2% (0.02), 1973 - not detected, 1974 - 0.8% (0.5), 1975 - 0.4% (0.5), 1976 - 0.4% (trace)(1); red meat - domestic 15200 samples, 0.2% pos, 0.007 ppm avg; poultry 11340 samples, 0.1% pos, 0 .005 ppm avg; leaf and stem vegetables - domestic 5319, 11.2% pos, 0.421 ppm avg; vine and ear vegetables - domestic 2954 samples, 2.2% pos, 0.012 ppm avg, imported 4117 samples, 1.3% pos, 0.004 ppm avg; beans - domestic 499 samples, 1.4% pos, 0.036 ppm avg, imported 365 samples, 1.3% pos, 0.007 ppm avg; root vegetables - domestic 3248 samples, 3.2% pos, 0.012 ppm avg; grains - domestic 947 samples, 2.6% pos, 0.025 ppm avg; processed vegetables - domestic 631 samples, 0.5% pos, 0.001 ppm avg; nuts - domestic 174 samples, 22.4% pos, 0.219 ppm avg; peanuts 148 samples, 31.1% pos, 0.587 ppm avg, max 3.78 ppm; soybeans 104 samples, 8.7% pos, 0.03 ppm avg, max 1.0 ppm(1). The percentage of composite samples testing positive for toxaphene and the daily intake in ug/kg body weight from 1963-69 was: 1964-65 - not detected, 1965-66 - 1.0% (2.0), 1966-67 - not detected, 1967-68 - 1.1% (2.0), 1968-69 - 3.6% (4.0)(2). In an adult total diet study conducted in the USA from Aug 1976-Sept 1977 of 300 composite food samples: 3.3% pos at 0.026-0.597 ppm(3); Oct 1977-Sept 1978, 240 food composites, 1.7% pos, 0.173-0.469 ppm(4).

D015; A solid waste containing toxaphene may or may not become characterized as a hazardous waste when subjected to the Toxicity Characteristic Leaching Procedure listed in 40 CFR 261.24, and if so characterized, must be managed as a hazardous waste.
P123; As stipulated in 40 CFR 261.33, when toxaphene, as a commercial chemical product or manufacturing chemical intermediate or an off-specification commercial chemical product or a manufacturing chemical intermediate, becomes a waste, it must be managed according to federal and/or state hazardous waste regulations. Also defined as a hazardous waste is any container or inner liner used to hold this waste or any residue, contaminated soil, water, or other debris resulting from the cleanup of a spill, into water or on dry land, of this waste. Generators of small quantities of this waste may qualify for partial exclusion from hazardous waste regulations (40 CFR 261.5(e)).
As the federal pesticide law FIFRA directs, EPA is conducting a comprehensive review of older pesticides to consider their health and environmental effects and make decisions about their future use. Under this pesticide reregistration program, EPA examines health and safety data for pesticide active ingredients initially registered before November 1, 1984, and determines whether they are eligible for reregistration. In addition, all pesticides must meet the new safety standard of the Food Quality Protection Act of 1996. Pesticides for which EPA had not issued Registration Standards prior to the effective date of FIFRA, as amended in 1988, were divided into three lists based upon their potential for human exposure and other factors, with List B containing pesticides of greater concern and List D pesticides of less concern. Toxaphene is found on List B. Case No: 2685; Pesticide type: insecticide; Case Status: No products containing the pesticide are actively registered ... The case /is characterized/ as "cancelled." Under FIFRA, pesticide producers may voluntarily cancel their registered products. EPA also may cancel pesticide registrations if registrants fail to pay required fees or make/meet certain reregistration commitments, or if EPA reaches findings of unreasonable adverse effects.; Active ingredient (AI): technical chlorinated camphene; AI Status: The active ingredient is no longer contained in any registered pesticide products ... "cancelled."
Listed as a hazardous air pollutant (HAP) generally known or suspected to cause serious health problems. The Clean Air Act, as amended in 1990, directs EPA to set standards requiring major sources to sharply reduce routine emissions of toxic pollutants. EPA is required to establish and phase in specific performance based standards for all air emission sources that emit one or more of the listed pollutants. Toxaphene is included on this list.

Toxaphene (polychlorinated camphenes) is an insecticidal mixture of >670 chemicals, which was widely used until the mid 1980s. Due to their lipophilic and volatile nature, these chemicals accumulate in animal and human tissues and continue to be a major contaminant in marine and freshwater biota. Cytotoxic and genotoxic effects in mammalian test systems suggest that toxaphene is a carcinogen and reports support the hypothesis that toxaphene could have tumor-promoting potential in human breast tissue. In order to examine the potential of toxaphene as an environmental endocrine disrupter, we investigated its effect on the estrogen receptor (ER) function in human breast cancer MCF-7 cells. Using transient gene expression experiments, we observed approximately 60% and 80% inhibition of the constitutive and 17beta-estradiol induced ER-dependent transactivation, respectively. The involvement of the ER in the ability of toxaphene to block the estrogen action was verified by cotransfection studies in ER-negative DMA-MB-231 cells. The interference of toxaphene with the ER mediated responses was supported by a significant suppression of endogenously expressed pS2 RNA and decreased levels of secreted pS2 protein. These reproducible results indicate that toxaphene can disturb hormonal signals mediated by the ER and suggest that these environmental chemicals have potential endocrine disrupting activities which may affect the reproductive health and increase the risk of carcinogenesis.

In part toxaphene is also metabolized by reduced nicotinamide adenine dinucleotide dependent mixed function oxidase in rat hepatic microsomal enzyme preparations. ...
In vitro studies were conducted with rat liver microsomal preparations. Metabolism of toxaphene was increased by addition of reduced glutathione & nicotinamide-adenine dinucleotide phosphate. In addition to dechlorination, some oxidation to hydroxyl and acidic cmpd occurred. Further study showed that aglycones were released by action of beta-glucuronidase and beta-sulfatase, indicating the presence of water releasing conjugates in vitro.
The metabolism of toxaphene in perfused bovine liver was studied. Two beef cows and one dairy calf had blood collected from the jugular vein and the liver was then removed. The blood was defibrinated and filtered; 100 milligrams oxytetracycline was added and then used as perfusate. The liver was cleaned and drained, then attached to the arterial side of a perfusion chamber. An ethanolic solution of toxaphene was added to give a concentration of 20 micrograms per gram in the blood. Samples of the perfusate were taken every 15 minutes until the end of the experiment when the liver was weighed and a sample taken. Recovery of toxaphene and the effect of blood on toxaphene were determined by circulating dosed blood without the liver. Blood samples were analyzed for toxaphene and dechlorinated metabolites were analyzed by gas liquid chromatography. By 15 minutes after dosing, approximately 75% of the toxaphene was taken up by the liver; 105 minutes after dosing, an additional 15% was taken up. The half-life of early rapid rate of decline and later rate of decline of toxaphene from the perfusate was 7 minutes and 86 minutes, respectively. The gas chromatographs showed that toxaphene components produced partially dechlorinated derivatives that degraded further with time. The response ratio between perfusate with liver and circulating blood without liver showed that toxaphene metabolism by the liver occurred by 15 minutes after dosing.

Toxaphene is absorbed through the intestines and lungs, then distributed mainly to fat tissues. Due to the complex composition of toxaphene, it requires various metabolic pathways to degrade, which involve dechlorination, dehydrodechlorination, and oxidation. Metabolism occurs primarily by hepatic mixed-function oxidases, and metabolites are excreted in the urine and faeces. (L107)

VerwendenToxaphene is an insecticide that contains over 200–700 chemicals and can exist as an yellow to amber solid or gas. Heavily used in the United States until 1982, its use was completely banned in 1990. Toxaphene was used primarily to control insects on cotton crops in the southern United States; it has also been used to control pests on livestock and to control unwanted fish in aquatic environments. Reports have indicated that fish are low metabolizers of toxaphene, whereas other aquatic life such as snails can be extensive metabolizers, thus reducing the toxicity of toxaphene to aquatic life other than fish (Isensee et al., 1979).
