[14][15][16] Most home uses of chlorpyrifos had already been banned in the U.S. and Canada since 2001. Other types of TCVP exposures, including residues on food, also pose worrisome health risks, particularly in combination with exposure from pet products, said Ms. Rotkin-Ellman. This includes ongoing observations on possible off-target harm to humans or ecosystems as well as the monitoring of resistance development.[4]. Methomyl is a carbamate insecticide introduced in 1966. [23] The chemical became widely used in residential settings, on golf course turf, as a structural termite control agent, and in agriculture. [26], The non-cancer health effects of chlordane compounds, which include diabetes, insulin resistance, migraines, respiratory infections, immune-system activation, anxiety, depression, blurry vision, confusion, intractable seizures as well as permanent neurological damage,[27] probably affects more people than cancer. It is applied to the skin as a cream or lotion. [24][25][9], In May 2003, the French Directorate-General of Food at the Ministry of Agriculture determined that a case of mass bee mortality observed in southern France was related to acute fipronil toxicity. [158] Their literature review concluded that there is no evidence for reproductive toxicity in rats, but that chlorpyrifos is potentially genotoxic. Cyclodiene derives its name from hexachlorocyclopentadiene, a precursor in its production. The molecule is similar to Chlorpyrifos ethyl, but with a O,O dimethyl chain. [98] A review of US studies, several European countries, Brazil and India found chlorpyrifos in nearly 15% of hive pollen samples and just over 20% of honey samples. [105] It was banned from residential use in South Africa as of 2010. [130], After years of research without a conclusion and cognizant of the court order to issue a final ruling, the EPA proposed to eliminate all tolerances for chlorpyrifos ("Because tolerances are the maximum residue of a pesticide that can be in or on food, this proposed rule revoking all chlorpyrifos tolerances means that if this approach is finalized, all agricultural uses of chlorpyrifos would cease. Among agricultural workers, chlorpyrifos has been associated with slightly increased risk of wheeze, a whistling sound while breathing due to obstruction of the airways. [56] Moreover, experiments with zebrafish showed significant detriments to survivability, reproductive processes, and motor function. The fight over a different organophosphate, chlorpyrifos, is another example of this. [50] They have also been shown to have a higher chance of developing autism, attention deficit problems, and developmental disorders. As a pesticide, chlorpyrifos is not regulated under the Toxic Substances Control Act (TSCA). A 2001 study by CSE had linked the aerial spraying of the pesticide with the growing health disorders in Kasaragode. ATSDR defines Minimal Risk Level as an estimate of daily human exposure to a dose of a chemical that is likely to be without an appreciable risk of adverse non-cancerous effects over a specific duration of exposure. PRINCIPLES OF SCHEDULING. This entry was posted [14] The US exported more than 140,000 lb of endosulfan from 2001 to 2003, mostly to Latin America,[92] but production and export has since stopped. The EPA also concluded, "[e]ndosulfan has relatively high potential to bioaccumulate in fish. Boric acid, more specifically orthoboric acid, is a compound of boron, oxygen, and hydrogen with formula B(OH) 3.It may also be called hydrogen borate or boracic acid. Endosulfan was the only pesticide applied to cashew plantations in the villages for 20 years, and had contaminated the village environment. Endosulfan is an off-patent organochlorine insecticide and acaricide that is being phased out globally. Another legal challenge was filed in 2019, aimed at forcing the agency to respond. Exposure during pregnancy may harm the mental development of children. [129][133] However, in a 2016 report, EPA scientists had not been able to find any level of exposure to the pesticide that was safe. Toxicity was linked to defective seed treatment, which generated dust. Under Trump", "Chlorpyrifos Revised Human Health Risk Assessment (2016)", "Children's Exposure to Chlorpyrifos and Parathion in an Agricultural Community in Central Washington State", "Dietary Intake and Its Contribution to Longitudinal Organophosphorus Pesticide Exposure in Urban/Suburban Children", "Exposures of 129 Preschool Children to Organochlorines, Organophosphates, Pyrethroids, and Acid Herbicides at Their Homes and Daycares in North Carolina", "Urinary biomarker, dermal, and air measurement results for 2,4-D and chlorpyrifos farm applicators in the Agricultural Health Study", "Urinary pesticide concentrations among children, mothers and fathers living in farm and non-farm households in Iowa", "Review of pesticide urinary biomarker measurements from selected US EPA children's observational exposure studies", "Community Exposures to Airborne Agricultural Pesticides in California: Ranking of Inhalation Risks", S Kegley et al., "Secondhand Pesticides", Pesticide Action Network North America, 2003, "Passive Sampling for Indoor and Outdoor Exposures to Chlorpyrifos, Azinphos-Methyl, and Oxygen Analogs in a Rural Agricultural Community", Air Monitoring for Chlorpyrifos in the Yakima Valley, Washington, April 2006, "Airborne Poisons: Pesticides in Our Air and in Our Bodies", "Heather Hansen, "Proper Pest Management Keeps Washington Fruit Crop Healthy", Seattle Post Intellegencer, Jan 19, 2007". [9] Exposure surpassing recommended levels has been linked to neurological effects, persistent developmental disorders, and autoimmune disorders. ToxFaqs: September, 1995. [48] A 2009 assessment concluded the endocrine disruption in rats occurs only at endosulfan doses that cause neurotoxicity. "There is a wealth of science demonstrating the detrimental effects of chlorpyrifos exposure to developing fetuses, infants, children and pregnant women. (Beyond Pesticides, October 19, 2022) Pet flea collars containing the insecticide tetrachlorvinphos (TCVP) are set to be banned by the U.S. Environmental Protection Agency, according to the agencys long overdue response to a petition from the Natural Resources Defense Council (NRDC). In the United States, chlordane was used for termite-treatment of approximately 30 million homes until it was banned in 1988. Endosulfan is subject to long-range atmospheric transport, i.e. "Douglas Fischer, "Toxins permeate Central Valley town", "Ban on domestic sale of insecticide welcomed by fisheries groups", "Domestic source 'likely' cause of Kennet pollution", "Pesticide Residues and Bees A Risk Assessment", "Four common pesticides, their mixtures and a formulation solvent in the hive environment have high oral toxicity to honey bee larvae", "Exposure to acetylcholinesterase inhibitors alters the physiology and motor function of honeybees", "Exposure to multiple cholinergic pesticides impairs olfactory learning and memory in honeybees", "UNEP/POPS/POPRC.17/5 Proposal to list chlorpyrifos in Annex A to the Stockholm Convention on Persistent Organic Pollutants", "Prohibition on the use of chlorpyrifos in Singapore", "Harmful pesticide banned in SA South Africa", "Changes to authorisations for products containing chlorpyrifos", "Concentrations and temporal trends in pesticide biomarkers in urine of Swedish adolescents, 20002017", "Summary of the Toxic Substances Control Act", "Chlorpyrifos; Receipt of Requests For End-Use Product Amendments and Cancellations", "E.P.A., Citing Risks to Children, Signs Accord to Limit Insecticide", "EPA Proposes Ending Use of Certain Pesticide on Foods, Citing Risk to Water", "Pesticide Action Network v.

Hydroxyfluorene can be converted to fluorenone by oxidation. [39], Chlorpyrifos poisoning was described by New Zealand scientists as the likely cause of death of several tourists in Chiang Mai, Thailand who developed myocarditis in 2011. [71][72][73] In at least one study, nicotine appeared to enhance chlorpyrifos detoxification. "[50] Increased incidences of cryptorchidism have been observed in other studies of endosulfan exposed populations. This prevents the opening of chloride ion channels normally encouraged by GABA, reducing the chloride ions' ability to lower a neuron's membrane potential. Ryan Jackson, Pruitt's chief of staff, said in an 8 March email that he had "scared" career staff into going along with the political decision to deny the ban, adding "[T]hey know where this is headed and they are documenting it well. However, chlorpyrifos applicators had a 15% lower cancer risk than the general public, which the study suggests indicates a link between chlorpyrifos application and lung cancer. In June, after several Freedom of Information Act requests, the EPA released a copy of Pruitt's March meeting schedule which showed that a meeting had been scheduled between Pruitt and Dow CEO Andrew Liveris at a hotel in Houston, Texas, on 9 March. The highly toxic pesticide has not been used on crops since 1987, yet was permitted for decades in flea collars where children could be intimately exposed to the chemical while petting and playing with the family pet. As a medication, it is used to treat scabies and lice. You can follow any responses to this entry through the RSS 2.0 feed. Toxicity in humans. [61], The Dow Chemical Company also developed Chlorpyrifos methyl in 1966, which had a lower acute toxicity (WHO class III), but this appears to be no longer in commercial use. Precise numbers of chlorpyrifos poisonings globally are not available. Well after their use as insecticides began, their chemical structures were determined by Hermann Staudinger and Lavoslav Ruika in 1924. The risk to infant and children's health and development is unambiguous. [18], The industrial synthesis of chlorpyrifos (3) is made by reacting 3,5,6-trichloro-2-pyridinol (TCPy) (1) with O,O-diethyl phosphorochloridothioate (2):[19], Chlorpyrifos was used in about 100 countries around the world to control insects in agricultural, residential, and commercial settings. it can travel long distances from where it is used. [2], The examples and perspective in this article, Brodan, Bolton insecticide, Chlorpyrifos-ethyl, Cobalt, Detmol UA, Dowco 179, Dursban, Empire, Eradex, Hatchet, Lorsban, Nufos, Paqeant, Piridane, Scout, Stipend, Tricel, Warhawk, others, InChI=1S/C9H11Cl3NO3PS/c1-3-14-17(18,15-4-2)16-9-7(11)5-6(10)8(12)13-9/h5H,3-4H2,1-2H3, InChI=1/C9H11Cl3NO3PS/c1-3-14-17(18,15-4-2)16-9-7(11)5-6(10)8(12)13-9/h5H,3-4H2,1-2H3, Except where otherwise noted, data are given for materials in their, The examples and perspective in this section. [101] Australia had, in 2008, announced endosulfan would not be banned. [5] The mixture that is composed of 147 components is called technical chlordane. 408. [59][60], Twelve people who had been exposed to chlorpyrifos were studied over periods of 1 to 4.5 years. [59], In 2009, the committee of scientific experts of the Stockholm Convention concluded, "endosulfan is likely, as a result of long range environmental transport, to lead to significant adverse human health and environmental effects such that global action is warranted.

[112][113], In 2007 Pesticide Action Network North America and Natural Resources Defense Council (collectively, PANNA) submitted an administrative petition requesting a chlorpyrifos ban. [137], In 2003, Dow agreed to pay $2million to New York state, in response to a lawsuit to end Dow's advertising of Dursban as "safe". [105], Brazil decreed total ban of the substance from July 31, 2013, being forbidden imports of the product from July 31, 2011, date in which national production and utilization begins to be phased out gradually. [70] In the lab, in rats and neural cells co-exposed to both nicotine and chlorpyrifos, nicotine appears to protect against chlorpyrifos acetylcholinesterase inhibition and reduce its effects on neurodevelopment. The EU and UK imposed a pesticide residue limit of 20 g/kg for apples and oranges. [31], 1,2,4,5,6,7,8,8-Octachloro-3a,4,7,7a-tetrahydro-4,7-methanoindane, Chlordan; Chlordano; Ortho; Octachloro-4,7-methanohydroindane, Except where otherwise noted, data are given for materials in their, The examples and perspective in this article, Origin, pathways of exposure, and processes of excretion, Toxicological Profile for Chlordane, U.S. Department Of Health and Human Services, Agency for Toxic Substances and Disease Registry. [51][52], A 2007 study by the California Department of Public Health found that women who lived near farm fields sprayed with endosulfan and the related organochloride pesticide dicofol during the first eight weeks of pregnancy are several times more likely to give birth to children with autism. Residual pesticides turn the infected cockroaches and their fluids into bait themselves. EPA also ignored the potential for a toddler to touch food or another object with pesticide-contaminated hands, and then place that food or object in their mouth. They also find it to enter through the digestive system, skin and membranes of the respiratory system. The extent of and mechanisms for these effects remain to be fully characterized. 2011: the Argentinian Service for Sanity and Agroalimentary Quality (SENASA) decided on August 8 that the import of endosulfan into the South American country will be banned from July 1, 2012 and its commercialization and use from July 1, 2013. [77], Children of agricultural workers are more likely to come into contact with chlorpyrifos. According to Dow, chlorpyrifos is registered for use in nearly 100 countries and is annually applied to approximately 8.5million crop acres. When it comes to protecting health and the environment, the agency drags its feet, strongly challenges criticism, and requires public interest groups to fight for years in the courts to implement critical protections. Carbofuran is a carbamate pesticide, widely used around the world to control insects on a wide variety of field crops, including potatoes, corn and soybeans.It is a systemic insecticide, which means that the plant absorbs it through the roots, and from there the plant distributes it throughout its organs where insecticidal concentrations are attained. Fipronil is highly toxic for crustaceans, insects (including bees and termites) and zooplankton, as well as rabbits, the fringe-toed lizard, and certain groups of gallinaceous birds. Poisons are not scheduled on the basis of a universal scale of toxicity. [104] Citing New Zealand's ban, the Australian Greens called for "zero tolerance" of endosulfan residue on food. [104] Chlorpyrifos is restricted from termite control in Singapore as of 2009. [128][129] These tolerances limit the amount of chlorpyrifos that can be applied to crops. [45][46] Chlorpyrifos has been suggested to have negative impacts on cognitive functions in the developing brain. Endosulfan: Request for Additional Information on Usage and Availability of Alternatives, PETITION TO BAN ENDOSULFAN AND REVOKE ALL TOLERANCES AND COMMENTS ON THE ENDOSULFAN UPDATED RISK ASSESSMENT (OPP-2002-0262-0067) BY THE NATURAL RESOURCES DEFENSE COUNCIL, "Open letter to Stephen Johnson, Administrator, U.S. Environmental Protection Agency: ban endosulfan", "Group sues to ban DDT-related pesticide", POPRC-4 Summary and Analysis, 20 October 2008, "Endosulfan and other chemicals being assessed for listing under the Stockholm Convention", "UN chemical body recommends elimination of the toxic pesticide endosulfan", "Australia finally bans endosulfan. Fipronil's specificity towards insects is believed to be due to its greater binding affinity to the GABAA receptors of insects, than to those of mammals, and to its action on GluCl channels, which do not exist in mammals. Poisons are not scheduled on the basis of a universal scale of toxicity. [38] A subsequent double-blind RCT, that treated patients who self-poisoned, found no benefit of pralidoxime, including specifically in chlorpyrifos patients. "[60] In May 2011, the Stockholm Convention committee approved the recommendation for elimination of production and use of endosulfan and its isomers worldwide. However, atropine does not affect acetylcholine at nicotinic receptors and thus is a partial treatment. A shipment of about 10 tonnes of endosulfan was illegally stowed on the ill-fated MV Princess of the Stars, a ferry that sank off the waters of Romblon (Sibuyan Island), Philippines, during a storm in June 2008. [132], The EPA has not updated the approximately 112 tolerances pertaining to food products and supplies since 2006. In finally forcing EPAs hand on chlorpyrifos, a federal court ruling took the agency to task, asserting, The EPA has had nearly 14 years to publish a legally sufficient response to the 2007 Petition [filed by environmental and farmworker groups]. In doing so, the agency noted label precautions it said would protect pet owners, including not allowing children to play with TVCP collars, keeping TCVP out of the reach of children, and washing hands after handling. [80] Certain other populations with higher likely exposure to chlorpyrifos, such as people who apply pesticides, work on farms, or live in agricultural communities, have been measured in the US to excrete TCPy in their urine at levels that are 5 to 10 times greater than levels in the general population. Between 1987 and 1996, fipronil was evaluated on more than 250 insect pests on 60 crops worldwide, and crop protection accounted for about 39% of total fipronil production in 1997. EPAs characteristic response to nonprofit groups critiquing their science stands in stark contrast to how it responds to industry groups doing the same. This page was last edited on 13 October 2022, at 20:08. It has been found by the Minutes-Association for Technical Coordination Fund in France that even at very low nonlethal doses for bees, the pesticide still impairs their ability to locate their hive, resulting in large numbers of forager bees lost with every pollen-finding expedition. [79][80], The Supreme Court passed interim order on May 13, 2011, in a Writ Petition filed by Democratic Youth Federation of India, (DYFI), a youth wing of Communist Party of India (Marxist) in the backdrop of the incidents reported in Kasargode, Kerala, and banned the production, distribution and use of endosulfan in India because the pesticide has debilitating effects on humans and the environment. In November 2016, the EPA reassessed its ban proposal after taking into consideration recommendations made by the agency's Science Advisory Panel which had rejected the EPA's methodology in quantifying the risk posed by chlorpyrifos. [52] Exposure to organophosphate pesticides in general has been increasingly associated with changes in children's cognitive, behavioral and motor performance. To remove chlordane from indoor air requires either ventilation (Heat Exchange Ventilation) or activated carbon filtration. [71], In 2011, EPA estimated that, in the general US population, people consume 0.009 micrograms of chlorpyrifos per kilogram of their body weight per day directly from food residue. These products were sold in the United States from 1948 to 1988. Overall, this will lead to its elimination from the global markets. A study by Embrandiri et al was also examined. Depending on the site of home treatment, the indoor air levels of chlordane can still exceed the Minimal Risks Levels (MRLs) for both cancer and chronic disease by orders of magnitude. The photodegradate MB46513 or desulfinylfipronil, appears to have a higher acute toxicity to mammals than fipronil itself by a factor of about 10. This results in an overabundance of neurons reaching action potential and likewise CNS toxicity via overstimulation. [47] It is not known whether endosulfan is a human teratogen (an agent that causes birth defects), though it has significant teratogenic effects in laboratory rats. day) for adults and children, respectively. [110] It may also be sold in ant and roach baits with childproof packaging. Minister for Energy, and Food and Civil Supplies Shobha Karandlaje, who has been spearheading a movement seeking a ban on endosulfan, said, "I am grateful to Chief Minister B.S. [109], Chlorpyrifos is sold in restricted-use products for certified pesticide applicators to use in agriculture and other settings, such as golf courses or for mosquito control. Poisons are not scheduled on the basis of a universal scale of toxicity. Specifically, the agency assumed that toddlers only interacted with one treated pet per day, for no more than one hour a day. [17], Two Frontline TopSpot products were determined by the New York State Department of Environmental Conservation to pose no significant exposure risks to workers applying the product. It is highly toxic to humans, livestock, pets, and wildlife. NRDC again challenged this decision, noting that EPAs analysis of the new test on the release of TCVP from pet collars was miscalculated and significantly underestimated exposure risks. Fipronil is classed as a WHO Class II moderately hazardous pesticide, and has a rat acute oral LD50 of 97mg/kg. This page was last edited on 23 August 2022, at 18:02. Available at URL: Center for Disease Control and Prevention (CDC). The metabolite MB 46136 is more toxic than the parent to freshwater fish (6.3 times more toxic to rainbow trout and 3.3 times more toxic to bluegill sunfish). [138] Manufacturers rejected the request. National Report on Human Exposure to Environmental Chemicals: Chemical Information: Chlordane. "[76], The [food only] exposures for chlorpyrifos are of risk concern for all population subgroups analyzed. [77] Indian Union Minister of Agriculture Sharad Pawar has ruled out implementing a similar ban at the national level despite the fact that endosulfan has banned in 63 countries, including the European Union, Australia, and New Zealand. [32], Children are more likely to experience muscle weakness rather than twitching; excessive saliva rather than sweat or tears; seizures; and sleepiness or coma. [54] Evidence of carcinogenicity in animals is mixed.[18]. [74] Children are estimated to consume a greater quantity of chlorpyrifos per unit of body weight from food residue, with toddlers the highest at 0.025 micrograms of chlorpyrifos per kilogram of their body weight per day. [42] [67] Some evidence indicates that children born to women with low PON1 may be particularly susceptible to chlorpyrifos exposure. The implications of this for other wildlife and ecology of the habitat remain unknown, but appear unlikely to be severe. [citation needed], Chlorpyrifos may affect other neurotransmitters, enzymes and cell signaling pathways, potentially at doses below those that substantially inhibit acetylcholinesterase. A review of that data resulted in minimal mitigation measures, and ultimately, the agency denied the petition. On 10 August 2015, the Ninth Circuit Court of Appeals in PANNA v. EPA ordered the EPA to respond to PANNA's petition by "revok[ing] all tolerances for the insecticide chlorpyrifos", den[ying] the Petition or [issuing] a "proposed or final tolerance revocation" no later than 31 October 2015. EPA must act swiftly to prohibit other dangerous uses of this toxic pesticide. Persistent health effects follow acute poisoning or from long-term exposure to low doses, and developmental effects appear in fetuses and children even at very small doses. Fipronil is also used in Brazil and studies on the stingless bee Scaptotrigona postica have shown adverse reactions to the pesticide, including seizures, paralysis, and death with a lethal dose of .54ng a.i./bee and a lethal concentration of .24ng a.i./l diet. Search, rescue, and salvage efforts were suspended when the endosulfan shipment was discovered, and blood samples from divers at the scene were sent to Malaysia for analysis. As of August 18, 2021, the U.S. Environmental Protection Agency (EPA) announced a ban on the use of chlorpyrifos on food crops in the United States. 13 Oct 2010. In a November 2016 press release, DOW argued that chlorpyrifos was "a critical tool for growers of more than 50 different types of crops in the United States" with limited or no viable alternatives. Yeddyurappa and members of the Cabinet for approving the ban. Related to enactment of the National COVID-19 Preparedness Plan, EPA issued guidance on Like other chlorinated cyclodiene insecticides, chlordane is classified as an organic pollutant hazardous for human health. [81][82][83], As of 2016, chlorpyrifos was the most used conventional insecticide in the US and was used in over 40 states; the top five states (in total pounds applied) are California, North Dakota, Minnesota, Iowa, and Texas. However, the rule was remanded by the U.S. "[116] The Environment News Service quoted the Dow AgroSciences' statement disagreeing with the EPA findings.[117]. [34][35][36][37], In mammals (including humans) fipronil overdose is characterized by vomiting, agitation, and seizures. Chlorpyrifos was patented in 1966 by Dow Chemical Company. PRINCIPLES OF SCHEDULING. One may ask: How many veterinarians prescribed these dangerous flea collars to pet owners, assuming that EPA has properly assessed exposure risks to their human owners? [131], The Dow Chemical Company is actively opposed to tolerance restrictions on chlorpyrifos and is currently lobbying the White House to, among other goals, pressure EPA to reverse its proposal to revoke chlorpyrifos food residue tolerances. In Australia, it is marketed under numerous trade names, including Combat Ant-Rid, Anthem, Clearout (used together with Pyriproxyfen in the Clearout PLUS version as an aerosol spray to control ants, cockroach and flies), Fipforce, Radiate and Termidor, and as generic fipronil. Farmers were given 270 days to destroy their stock, while a 90-day deadline was also given to farmers to return the chemicals for destruction, as their possession is considered illegal by the Department of Agriculture. This genus is defined as aerobic, Gram It is suggested that adolescents differ from adults in the metabolism of these compounds due to the maturation of organs in adolescents. [123] Both men were featured speakers at an energy conference. The dermal LD50 in rats is greater than 2000mg/kg and 1000 to 2000mg/kg in rabbits. [23] In 2001, chlorpyrifos ranked 15th among pesticides used in the United States, with an estimated 8 to 11 million pounds applied. [30] The functional basis for this toxic effect is now understood: the synergy between fipronil and the pathogenic fungus induces changes in male bee physiology leading to infertility. [107], Chlorpyrifos has not been permitted for agricultural use in Sweden at all[108], In the United States, several laws directly or indirectly regulate the use of pesticides. This corroborates the lack of residues in worker-exposure studies. These values are highly toxic in Scaptotrigona postica and bees in general. [137], In 2009, to protect threatened salmon and steelhead under CWA and ESA, EPA and National Marine Fisheries Service (NMFS) recommended limits on the use of chlorpyrifos in California, Idaho, Oregon and Washington and requested that manufacturers voluntarily add buffer zones, application limits and fish toxicity to the standard labeling requirements for all chlorpyrifos-based products. EPA Bans Pesticide Found on Cucumbers, Zucchini, Green Beans and Other Vegetables. To Ban Chlorpyrifos, Pesticide Tied to Children's Health Problems", "EPA sets limits on the amount of pesticides that may remain in foods", "US Environmental Protection Agency Office of Pesticide Programs Reregistration Eligibility Decision for Chlorpyrifos", "Compliance Policy Guides CPG Sec. [45] There are several studies observed in animals that show that chlorpyrifos alters the expression of essential genes that assist in the development of the brain. [32][45] By irreversibly inhibiting acetylcholinesterase, chlorpyrifos leads to a build-up of acetylcholine between neurons and a stronger, longer-lasting signal to the next neuron. Briefing presspersons after the State Cabinet meeting, Minister for Higher Education V.S. Lindane, also known as gamma-hexachlorocyclohexane (-HCH), gammaxene, Gammallin and benzene hexachloride (BHC), is an organochlorine chemical and an isomer of hexachlorocyclohexane that has been used both as an agricultural insecticide and as a pharmaceutical treatment for lice and scabies.. Lindane is a neurotoxin that interferes with
