for a 20 kg child. Traditionally, gastric lavage or nasogastric aspiration of gastric contents are the most common methods employed in ethylene glycol poisoning. According to OSHA (Occupational Safety and Health Administration), Ethylene Oxide (ETO) is a human-made, highly toxic, colorless, flammable gas that, at room temperature, produces a sweet odor. The bittering agent is thought to stop ingestion as part of the human defense against ingestion of harmful substances is rejection of bitter tasting substances. Additionally, as a side effect of the first two steps of metabolism, an increase in the blood concentration of lactic acid occurs contributing to lactic acidosis. Initially it is metabolized by alcohol dehydro… [2] When broken down by the body it results in glycolic acid and oxalic acid which cause most of the toxicity. [22] Ethylene glycol is not well absorbed through skin meaning poisoning following dermal exposure is also uncommon. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. Ethylene glycol (C2H6O2) is a toxic alcohol that is found in various household and industrial agents. 2007 Sep;25(7):799-803. doi: 10.1016/j.ajem.2007.01.017. Ethylene glycol poisoning is poisoning caused by drinking ethylene glycol. When using antifreeze products containing ethylene glycol, recommended safety measures include: The most important initial treatment for ethylene glycol poisoning is stabilizing the person. 13). 1988 Jan;84(1):145-52. Ethylene glycol in biological fluids can be determined by gas chromatography. Ashurst JV, Nappe TM. If patients start off with a baseline osmolality on the lower end of normal, they could have a clinically significant ethylene glycol intoxication with a normal osmolal gap. 12). The antidotes for ethylene glycol poisoning are ethanol and fomepizole. [26][27], The increased osmolal gap is caused by the ethylene glycol itself. "[12] Since 1994, federal airports must comply with the Glycol Guidelines of the Canadian Environmental Protection Act, monitoring and reporting on concentrations of glycols in surface water. The formation of acid metabolites also causes inhibition of other metabolic pathways, such as oxidative phosphorylation. As ethylene glycol is rapidly absorbed, gastric decontamination is unlikely to be of benefit unless it is performed within 60 minutes of ingestion. Clin Toxicol (Phila) 2017 Dec;55(10):1072-1252. Trends in toxic alcohol exposures in the United States from 2000 to 2013: a focus on the use of antidotes and extracorporeal treatments. That corresponds to an osmolal shift of only 3 mOsm/L.  |  Ethylene glycol is chemically broken down in the body into toxic compounds. As it has a toxic effect and, in high doses, can cause seizures and even coma, it has not been authorised for use in the food industry in Europe since 1981. The toxic mechanism of ethylene glycol poisoning is mainly due to the metabolites of ethylene glycol. [78], CS1 maint: DOI inactive as of December 2020 (. This site needs JavaScript to work properly. The primary treatments are either ethanol or fomepizole and, occasionally, dialysis. That is roughly 16 mL of 50% ethylene glycol for an 80 kg adult and 4 mL for a 20 kg child. In cats, this stage occurs 12–24 hours after consuming antifreeze; in dogs, at 36–72 hours after consuming antifreeze. [77] Large new airports may be required to collect 60 percent of aircraft deicing fluid after deicing. Similar to ethanol, it causes intoxication, followed by drowsiness or coma. Post harvest handlers must do everything they can to maintain the best possible environmental conditions for those delicate parcels. In a fire, the following hazardous materials may be generated: very toxic carbon monoxide, carbon dioxide; flammable hydrogen; toxic, flammable aldehydes. [7] Seizures may occur due to a direct effect. [64][66][67] Three follow up studies targeting limited populations or suicidal persons to assess the efficacy of bittering agents in preventing toxicity or death have, however, shown limited benefit of bittering ethylene glycol preparations in these two populations. However, acidosis has a large number of differential diagnosis, including poisoning from methanol, salicylates, iron, isoniazid, paracetamol, theophylline, or from conditions such as uremia or diabetic and alcoholic ketoacidosis. [2] Other treatments may include sodium bicarbonate, thiamine, and magnesium. According to OSHA (Occupational Safety and Health Administration), Ethylene Oxide (ETO) is a human-made, highly toxic, colorless, flammable gas that, at room temperature, produces a sweet odor. [12] It is also used in manufacturing polyester products. [1] It may be drunk accidentally or intentionally in a suicide attempt. [73] The process of biodegrading of glycols also increases the risk to organisms, as oxygen levels become depleted in surface waters (p. Most ethylene glycol poisonings occur due to the ingestion of antifreeze. In vitro percutaneous absorption of [14C] ethylene glycol. The impact of bittering agents on pediatric ingestions of antifreeze. -, Gummin DD, Mowry JB, Spyker DA, Brooks DE, Fraser MO, Banner W. 2016 Annual Report of the American Association of Poison Control Centers' National Poison Data System (NPDS): 34th Annual Report. Toxic Exposure to Ethylene Oxide Results in Lawsuits. Ng PCY, Long BJ, Davis WT, Sessions DJ, Koyfman A. Intern Emerg Med. Ethylene glycol binds with water, so it can be rinsed and diluted. Ethylene glycol exposures can cause varying degrees of toxicity and management generally requires supportive care, close laboratory monitoring and antidotal therapy. As activated charcoal does not adsorb glycols, it is not recommended as it will not be effective at preventing absorption. Ethylene oxide (EO) is an environmental pollutant and is toxic to humans. Hemodialysis is usually indicated in people with severe metabolic acidosis (blood pH less than 7.3), kidney failure, severe electrolyte imbalance, or if the person's condition is deteriorating despite treatment. In this situation stabilization of the person including airway management with intubation should be performed in preference to gastrointestinal decontamination. Disposing of used antifreeze only by taking to a service station. Although a naturally occurring plant hormone, ethylene can be dangerous, especially when handled incorrectly. [7] Urine microscopy can reveal needle or envelope-shaped calcium oxalate crystals in the urine which can suggest poisoning; although these crystals may not be present until the late stages of poisoning. Both these acids accumulate causing acidosis, which can lead to kidney problems and the formation of calcium oxalate (kidney stones). Ethylene oxide gas is toxic, carcinogenic, and very explosive. NLM [23], As many of the clinical signs and symptoms of ethylene glycol poisoning are nonspecific and occur in many poisonings the diagnosis is often difficult. Poison control centers often use more than a lick or taste in a child or more than a mouthful in an adult as a dose requiring hospital assessment. Following ingestion of antifreeze products containing ethylene glycol and fluorescein, a Wood's lamp may reveal fluorescence of a person's mouth area, clothing, vomitus, or urine which can help to diagnose poisoning. Keeping pets and small children away from the area when draining the car radiator. [7], Other laboratory abnormalities may suggest poisoning, especially the presence of a metabolic acidosis, particularly if it is characterized by a large anion gap. Ethylene Oxide a highly toxic, flammable chemical utilized in the manufacturing of ethylene glycol. The glycolic acid is then metabolized to glyoxylic acid and finally to oxalic acid. [6][43] Cats must be treated within 3 hours of ingesting of antifreeze to be effective, while dogs must be treated within 8–12 hours of ingestion. At room temperature, ethylene oxide is a flammable colorless gas with a sweet odor. If hypocalcemia occurs it can be treated with calcium replacement although calcium supplementation can increase the precipitation of calcium oxalate crystals leading to tissue damage. Congress classified it as a “hazardous air pollutant,” according to the … Toxic alcohol diagnosis and management: an emergency medicine review. [1][4] The diagnosis may be suspected when calcium oxalate crystals are seen in the urine or when acidosis or an increased osmol gap is present in the blood. The safe transportation of perishable products, whether fruits, vegetables or fresh cut flowers from the field to the consumer is tricky business. Ethylene glycol monobutyl ether (EGBE) (2-Butoxyethanol) - removed from the list of hazardous air pollutants (glycol ethers category) in November 2004 - Federal Register - November 29, 2004 (69 FR 69320). It has been shown to be highly effective in the removal of ethylene glycol and its metabolites from the blood. 2018 Apr;13(3):375-383. doi: 10.1007/s11739-018-1799-9. [3] Those affected are often adults and male. However, it is very useful as a chemical and can be found in many household items such as detergents, cosmetics, etc. [7] In this situation a helpful test to diagnose poisoning is the measurement of the osmolal gap. Copyright © 2020, StatPearls Publishing LLC. This antidotal treatment forms the mainstay of management of ethylene glycol poisoning. The toxicity of ethylene glycol comes from its metabolism to glycolic acid and oxalic acid. [28] Additionally, the presence of other alcohols such as ethanol, isopropanol, or methanol or conditions such as alcoholic or diabetic ketoacidosis, lactic acidosis, or kidney failure may also produce an elevated osmolal gap leading to a false diagnosis. [14] Accumulation of glycolic acid in the body is mainly responsible for toxicity. Ethylene glycol has a sweet taste and is often accidentally or intentionally ingested. The primary danger is its sweet taste, so children and animals can eat it, and it is toxic. I-3).  |  He continued his work with the compound and eventually … [68] Similarly, White found that adding bittering agents did not decrease the frequency or severity of antifreeze poisonings in children under the age of 5. Ethylene is used as an anesthetic, a refrigerant, and to make other chemicals as polymers and plastics. The presence of a large osmolal gap supports a diagnosis of ethylene glycol poisoning. [12], The three main systems affected by ethylene glycol poisoning are the central nervous system, metabolic processes, and the kidneys. Ethylene | CH2=CH2 or (C2H4)n or C2H4 | CID 6325 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more. Even a small amount of this liquid can be harmful. Seizures may occur due to a direct effect. [citation needed], Ethylene glycol has a low vapor pressure; it does not evaporate readily at normal temperatures and therefore high concentrations in air or intoxication are unlikely to occur following inhalational exposures. [69] Additionally, another study by White found that suicidal persons are not deterred by the bittered taste of antifreeze in their attempts to kill themselves. [36], Following decontamination and the institution of supportive measures, the next priority is inhibition of further ethylene glycol metabolism using antidotes. [2], Signs of ethylene glycol poisoning depend upon the time after ingestion. Ethylene Oxide gases are hazardous substances utilized in the production of ethylene glycol used in numerous products, including pharmaceuticals, polyurethane foam, adhesives, detergents, textiles, … [76] Considering factors such as the "seasonal nature of releases, ambient temperatures, metabolic rates and duration of exposure", Environment Canada stated in 2014 that "it is proposed that ethylene glycol is not entering the environment in a quantity or concentration or under conditions that have or may have an immediate or long-term harmful effect on the environment or its biological diversity". In smaller amounts, ethylene oxide is used as a pesticide and a sterilizing agent. A similar result was found in Michigan when the state analyzed the population near a … Ethylene glycol exposure can be extremely dangerous, with significant morbidity and mortality if … [42], Treatment for antifreeze poisoning needs to be started as soon after ingestion as possible to be effective; the earlier treatment is started, the greater the chance of survival. ETHYLENE page 2 of 6 This Fact Sheet is a summary source of information of all potential and most severe health hazards that may result from exposure. HHS Ethylene is not toxic, but is a simple asphyxiant. [26] People receiving ethanol therapy also require frequent blood ethanol concentration measurements and dosage adjustments to maintain a therapeutic ethanol concentration. [7][8], The most common source of ethylene glycol is automotive antifreeze or radiator coolant, where concentrations are high. https://en.wikipedia.org/w/index.php?title=Ethylene_glycol_poisoning&oldid=996426608, Toxic effects of substances chiefly nonmedicinal as to source, CS1 maint: DOI inactive as of December 2020, Articles with dead external links from September 2017, Articles with permanently dead external links, Short description is different from Wikidata, Articles with unsourced statements from July 2019, Articles lacking reliable references from October 2012, Wikipedia articles needing clarification from March 2012, Wikipedia medicine articles ready to translate, Creative Commons Attribution-ShareAlike License, Stage 1 (30 minutes to 12 hours) consists of. The goal of pharmacotherapy is to prevent the formation of these metabolites. Ethylene vinyl acetate is a type of plastic — a polymer with a wide variety of uses, both residential and industrial. 245). [44] Less commonly it has been used as a means of homicide. What is ethylene oxide? [5] An outbreak of deaths in 1937 due to a medication mixed in a similar compound, diethylene glycol, resulted in the Food, Drug, and Cosmetic Act of 1938 in the United States, which mandated evidence of safety before new medications could be sold. [12] A report prepared for the World Health Organization in 2000 stated that laboratory tests exposing aquatic organisms to stream water receiving runoff from airports have shown toxic effects and death (p. When considering the control of environmental conditions, dont overlook the destructive power of ethylene gas Mother Natures silent killer. [52] In Australia there were 17 cases reported to the Victorian poison center and 30 cases reported to the New South Wales poison center in 2007. [18][19][20] In the EU classification of dangerous substances it is 'harmful' (Xn) while more toxic substances are classified as 'toxic' (T) or 'very toxic' (T+). An ethylene glycol level >20 mg/dL is regarded as potentially toxic. -. [46][47][48][49] The most significant long-term complication is related to the kidneys. Jun 26, Methanol Toxicity. Get the latest public health information from CDC: https://www.coronavirus.gov, Get the latest research information from NIH: https://www.nih.gov/coronavirus, Find NCBI SARS-CoV-2 literature, sequence, and clinical content: https://www.ncbi.nlm.nih.gov/sars-cov-2/. People therefore must be monitored in an intensive care unit. In an effort to prevent poisoning, often a bittering agent called denatonium benzoate, known by the trade name Bitrex, is added to ethylene glycol preparations as an adversant to prevent accidental or intentional ingestion. The disadvantage of fomepizole is that it is expensive. Stage 3 (24 to 72 hours) kidney failure is the result of ethylene glycol poisoning. [9] Once kidney failure develops, the prognosis is poor. [25] Many hospital laboratories do not have the ability to perform this blood test and in the absence of this test the diagnosis must be made based on the presentation of the person. The U.S. Environmental Protection Agency generally puts substances which are lethal at more than 30 g to adults in Toxicity Class III. [60] In the United States there were 5816 cases reported to poison centers in 2002. [9] Some people put antifreeze into their cabin's toilet to prevent it from freezing during the winter, resulting in toxicities when animals drink from the toilet. It’s rare, but it’s real. [64][68][69] Specifically, Mullins finds that bittering of antifreeze does not reduce reported cases of poisoning of preschoolers in the US state of Oregon. Because ethanol has a much higher affinity for alcohol dehydrogenase, about a 100-times greater affinity, it successfully blocks the breakdown of ethylene glycol into glycolaldehyde, which prevents the further degradation. Explosions can be horrific in magnitude, and extreme care must be taken. [24], In addition to antidotes, an important treatment for poisoning is the use of hemodialysis. Ethylene glycol (C2H6O2) is a toxic alcohol that is found in various household and industrial agents. Treasure Island (FL): StatPearls Publishing; 2020 Jan. 2020 Jun 26. J.J. Mackenzie, "Prevent Antifreeze Poisoning", in Laurie Halse Anderson, elevated blood concentration of potassium, EU classification of dangerous substances, "College of Veterinary Medicine: Pet Health Topics: Antifreeze Poisoning", "Ethylene glycol: an estimate of tolerable levels of exposure based on a review of animal and human data", "Antifreeze Poisoning in Dogs & Cats (Ethylene Glycol Poisoning)", "Severe ethylene glycol intoxication with multisystem failure", "Government of Canada: Environment Canada: Ethylene Glycol (Final Content)", "Cerebral computed tomography of ethylene glycol intoxication", "Ethylene glycol poisoning: toxicokinetic and analytical factors affecting laboratory diagnosis", "Fomepizole in the treatment of ethylene glycol poisoning", "Oklahoma Veterinary Medical Association: ASPCA answers questions about antifreeze poisoning", "Ethylene glycol ingestion treated only with fomepizole", "[Fatal chronic oxalosis after sublethal ethylene glycol poisoning]", "Experiences of the Czech toxicological information centre with ethylene glycol poisoning", "Ethylene glycol toxicosis in a free-ranging raccoon (Procyon lotor) from Prince Edward Island", "The Merck Veterinary Manual: Overview of Ethylene Glycol Toxicity", "General properties, irritant and toxic actions of ethylene glycol", "Concise International Chemical Assessment Document 22: Ethylene Glycol: Environmental Aspects", "Preliminary Data Summary: Airport Deicing Operations (Revised)", "Glycol Mitigation Strategies: The Canadian Approach". [58][59] Children or animals may be exposed by accidental ingestion; children and animals often consume large amounts due to ethylene glycol having a sweet taste. [7], Fomepizole is a potent inhibitor of alcohol dehydrogenase; similar to ethanol, it acts to block the formation of the toxic metabolites. [7] If hemodialysis is not available, then peritoneal dialysis also removes ethylene glycol, although less efficiently. [4] Deaths from ethylene glycol have been reported as early as 1930. [7], The kidney toxicity of ethylene glycol occurs 24 to 72 hours post ingestion and is caused by a direct cytotoxic effect of glycolic acid. [1], Ethylene glycol is a colorless, odorless, sweet liquid, commonly found in antifreeze. COVID-19 is an emerging, rapidly evolving situation. Cases of permanent kidney damage, often requiring chronic dialysis or kidney transplantation, have been reported after severe poisoning. Ethylene glycol is metabolised by oxidation forming 2 major toxic metabolites. [24] Intubation and respiratory support may be required in severely intoxicated people; people with hypotension require treatment with intravenous fluids and possibly vasopressors. A toxic dose requiring medical treatment varies but is considered more than 0.1 mL per kg body weight (mL/kg) of pure substance. [17], The orally lethal dose in humans has been reported as approximately 1.4 mL/kg of pure ethylene glycol. [75] Detailed mitigation plans include storage and handling issues (p. 27), spill response procedures, and measures taken to reduce volumes of fluid (p. of 50% ethylene glycol for an 80 kg adult and 56 mL (2 oz.) [7] The increase in metabolites may cause encephalopathy or cerebral edema. 12). The first to form is glycolic acid which is further oxidised to oxalic acid. Am J Emerg Med. Effects from short-term exposure to high levels of ethylene oxide in humans can include central nervous system depression and irritation of the eyes and mucous membranes. [72] Numerous cases of poisoning have been reported since then, and it has been shown to be toxic to humans. The term “toxic alcohols” is a collective term that includes methanol, ethylene glycol, and isopropyl alcohol. NIH [73] Field studies in the vicinity of an airport have reported toxic signs consistent with ethylene glycol poisoning, fish kills, and reduced biodiversity, although those effects could not definitively be ascribed to ethylene glycol (p. [24][36][37] Fomepizole has been shown to be highly effective as an antidote for ethylene glycol poisoning. It and its toxic byproducts first affect the central nervous system (CNS), then the heart, and finally the … Ethylene oxide is used especially in the synthesis of ethylene glycol and as a sterilizing agent for medical supplies and foods, as a fumigant and as an insecticide. [7] The rate-limiting step in this cascade is the conversion of glycolic to glyoxylic acid. Without oxalic acid formation, the nephrotoxic effects can be avoided, but the ethylene glycol is still present in the body. [24] It is most reliably diagnosed by the measurement of the blood ethylene glycol concentration. The substance may be toxic to kidneys, liver, centr al nervous system (CNS). Those who have either worked at plants where ethylene oxide is found or residents that live near plants that emit ethylene oxide have filed lawsuits against various companies who they say are responsible … [9] Small amounts of ethylene glycol may be contained in holiday ornaments such as snow globes. "[74], In Canada, Environment Canada reports that "in recent years, management practices at Canada’s major airports have improved with the installation of new ethylene glycol application and mitigation facilities or improvements to existing ones. Am J Med. In: StatPearls [Internet]. [77] Airports that discharge the collected aircraft deicing fluid directly to waters of the U.S. must also meet numeric discharge requirements for chemical oxygen demand. These toxic substances also affect the cardiopulmonary system and can cause renal failure. In: StatPearls [Internet]. [64] These studies did not focus on poisoning of domestic pets or livestock, for example, or inadvertent exposure to bittered antifreeze among a large population (of non-preschool age children). [10] The toxic mechanism of ethylene glycol poisoning is mainly due to the metabolites of ethylene glycol. Ethylene is not harmful or toxic to humans; however, at extremely high concentrations it is combu… It is used primarily to produce other chemicals, including antifreeze. If antifreeze is placed in toilets, ensuring the lid is down and the door closed. Hemodialysis is used to enhance the removal of unmetabolized ethylene glycol, as well as its metabolites from the body. In fact, one comprehensive lifetime exposure study of workers in ethylene oxide production facilities found no statistically significant excess cancer risk due to ethylene oxide exposure. [2] Hemodialysis may also be used in those where there is organ damage or a high degree of acidosis. [1] Long term outcomes may include kidney failure and brain damage. Stage 2 (12 to 36 hours) where signs of "alcohol" poisoning appear to resolve, underlying severe internal damage is still occurring. [17] Additionally, ethylene glycol was the most common chemical responsible for deaths reported by US poison centers in 2003. [7] The usefulness of gastric lavage has, however, been questioned, and it is now no longer used routinely in poisoning situations. [74], Once kidney failure has developed in dogs and cats, the outcome is poor. 28). [7] The most significant effect is accumulation of calcium oxalate crystals in the kidneys which causes kidney damage leading to oliguric or anuric acute kidney failure. CNS depression begins soon after exposure, lasting for up to 12 hours after ingestion. USA.gov. Ethanol is readily available in most hospitals, is inexpensive, and can be administered orally as well as intravenously. 2010;53(1):19-23. [17] People who develop severe central nervous system manifestations or stroke who survive may have long term neurologic dysfunction; in some cases they may recover, although convalescence may be prolonged. Ethylene glycol is toxic and, if ingested, can cause fatal poisoning. [30][31], Antifreeze products for automotive use containing propylene glycol in place of ethylene glycol are available, and are generally considered safer to use, as it possesses an unpleasant taste in contrast to the perceived "sweet" taste of toxic ethylene glycol-based coolants, and only produces lactic acid in an animal's body, as their muscles do when exercised. Oxalic acid binds with calcium to form calcium oxalate crystals which may deposit and cause damage to many areas of the body including the brain, heart, kidneys, and lungs. 1993 Jul-Sep;3(3):277-84. [44] People who present early to medical facilities and have prompt medical treatment typically will have a favorable outcome. [26] People with significant poisoning often present in a critical condition. Duration of … Ingestion of this liquid can lead to shock or even death. [61][62] However, these numbers may underestimate actual numbers because not all cases attributable to ethylene glycol are reported to poison control centers. [7] Sodium bicarbonate should be used cautiously as it can worsen hypocalcemia by increasing the plasma protein binding of calcium. Clipboard, Search History, and several other advanced features are temporarily unavailable. Ethylene glycol exposure can be extremely dangerous, with significant morbidity and mortality if left untreated. [16], Ethylene glycol involved in aircraft de-icing and anti-icing operations is released onto land and eventually to waterways. Pharmaceutical grade ethanol is usually given intravenously as a 5 or 10% solution in 5% dextrose, but it is also sometimes given orally in the form of a strong spirit such as whisky, vodka, or gin. [1] Later symptoms may include a decreased level of consciousness, headache, and seizures. [7] The use of these agents is based on theoretical observations and there is limited evidence to support their use in treatment; they may be of particular benefit in people who could be deficient in these vitamins such as those who are malnourished or alcoholic. When an individual consumes ethylene glycol, it will be metabolized by the body in the similar way that it metabolizes ethyl alcohol. [45] Alternatively, people presenting late with signs and symptoms of coma, hyperkalemia, seizures, or severe acidosis have a poor prognosis. [7] The central nervous system is affected early in the course of poisoning as the result of a direct action of ethylene glycol. [9], The most significant source of ethylene glycol is from aircraft de-icing and anti-icing operations, where it is released onto land and eventually to waterways near airports experiencing cold winter climates. Large anion gap acidosis is usually present during the initial stage of poisoning. Although survival with medical treatment has occurred with doses much higher than this, death has occurred with 30 mL of the concentrate in an adult. Ethylene is Explosive! [5] Antifreeze products sometimes have a substance to make it bitter added to discourage drinking by children and other animals but this has not been found to be effective. [12] In 2006, approximately 1540 kilotonnes of ethylene glycol were manufactured in Canada by three companies in Alberta, with most of the production destined for export. [2] Treatment consists of stabilizing the person, followed by the use of an antidote. [7] People presenting with metabolic acidosis or seizures require treatment with sodium bicarbonate and anticonvulsives such as a benzodiazepine respectively. [9], Generally, if the person is treated and survives then a full recovery is expected. French chemist Charles-Adolphe Wurtz first synthesized ethylene glycol in 1859 from potassium hydroxide using a saponification process similar to that used to produce commercial soaps. [14][41] Hemodialysis also has the added benefit of correcting other metabolic derangements or supporting deteriorating kidney function. The toxic metabolic by-products of ethylene glycol metabolism cause a build-up of acid in the blood (metabolic acidosis). Ethylene glycol, hazardous substance in the household. [50][51], Ethylene glycol poisoning is a relatively common occurrence worldwide. [1], Early treatment increases the chance of a good outcome. EO sterilization cycles must be designed to avoid conditions or parameters that may be explosive. 245). [70] An online veterinary manual provides information on lethal doses of ethylene glycol for chicken, cattle, as well as cats and dogs, adding that younger animals may be more susceptible. [32][unreliable source?]. [12], In the U.S., airports are required to obtain stormwater discharge permits and ensure that wastes from deicing operations are properly collected and treated. Poisoning of a raccoon was diagnosed in 2002 in Prince Edward Island, Canada. Ethylene glycol is a colorless, odorless, sweet-tasting chemical. [1] Diagnosis may be confirmed by measuring ethylene glycol levels in the blood; however, many hospitals do not have the ability to perform this test. [1] Toxicity and death may occur after drinking even a small amount. Ethylene glycol in itself is not The central nervous system is affected early in the course of poisoning as the result of a direct action of ethylene glycol. It is eventually excreted in the urine, but supportive therapy for the CNS depression and metabolic acidosis will be required until the ethylene glycol concentrations fall below toxic limits. , close laboratory monitoring and antidotal therapy ; treasure Island ( FL:..., ethylene glycol is still present in a critical condition of correcting other metabolic derangements or supporting deteriorating kidney..
