[75] Detailed mitigation plans include storage and handling issues (p. 27), spill response procedures, and measures taken to reduce volumes of fluid (p. 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. [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.  |  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. 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. Ethylene Glycol is a common component of engine coolant, or antifreeze. 13). [9] Other sources of ethylene glycol include windshield deicing agents, brake fluid, motor oil, developing solutions for hobby photographers, wood stains, solvents, and paints. It and its toxic byproducts first affect the central nervous system (CNS), then the heart, and finally the … 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. In: StatPearls [Internet]. [55][56][57] Many cases of poisoning are the result of using ethylene glycol as a cheap substitute for alcohol or intentional ingestions in suicide attempts. [46][47][48][49] The most significant long-term complication is related to the kidneys. Treasure Island (FL): StatPearls Publishing; 2020 Jan–. [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. [10][24] Often both antidotal treatment and hemodialysis are used together in the treatment of poisoning. 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. Even a small amount of this liquid can be harmful. [22] Ethylene glycol is not well absorbed through skin meaning poisoning following dermal exposure is also uncommon. Ethylene is produced in petrochemical processes, as steam cracking where hydrocarbons and steam are heated to 750–950 °C. Ethylene glycol is toxic and, if ingested, can cause fatal poisoning. The presence of a large osmolal gap supports a diagnosis of ethylene glycol poisoning. The glycolic acid is then metabolized to glyoxylic acid and finally to oxalic acid. It has been shown to be highly effective in the removal of ethylene glycol and its metabolites from the blood. [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. [7] Sodium bicarbonate should be used cautiously as it can worsen hypocalcemia by increasing the plasma protein binding of calcium. 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. [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). [71], Ethylene glycol was once thought innocuous; in 1931 it was suggested as being suitable for use as a vehicle or solvent for injectable pharmaceutical preparations. Ingestion of this liquid can lead to shock or even death. The primary treatments are either ethanol or fomepizole and, occasionally, dialysis. The antidotes for ethylene glycol poisoning are ethanol and fomepizole. What are the stability and reactivity hazards of ethylene … [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. NIH [44] Less commonly it has been used as a means of homicide. When considering the control of environmental conditions, dont overlook the destructive power of ethylene gas Mother Natures silent killer. 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. [24], In addition to antidotes, an important treatment for poisoning is the use of hemodialysis. Ethylene glycol in biological fluids can be determined by gas chromatography. [32][unreliable source?]. Poisoning of a raccoon was diagnosed in 2002 in Prince Edward Island, Canada. It’s rare, but it’s real. [50][51], Ethylene glycol poisoning is a relatively common occurrence worldwide. -. 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. 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". [9] Once kidney failure develops, the prognosis is poor. Ethylene is Explosive! Without oxalic acid formation, the nephrotoxic effects can be avoided, but the ethylene glycol is still present in the body. [7] The rate-limiting step in this cascade is the conversion of glycolic to glyoxylic acid. [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. The toxic mechanism of ethylene glycol poisoning is mainly due to the metabolites of ethylene glycol. Colorless, odorless, flammable, toxic gaseous cyclic ether with a sweet ether-like smell. Toxic Inhalation of Ethylene Glycol: A Pharmacological Improbability To the Editor: Poison center specialists and medical toxicologists are often confronted with unusual exposures or exposure histories. [36], Following decontamination and the institution of supportive measures, the next priority is inhibition of further ethylene glycol metabolism using antidotes. [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. In vitro percutaneous absorption of [14C] ethylene glycol. ANTIFREEZE POISONING… VODKA AS AN ANTIDOTE? [24][36][37] Fomepizole has been shown to be highly effective as an antidote for ethylene glycol poisoning. Ethylene oxide gas is toxic, carcinogenic, and very explosive. Disposing of used antifreeze only by taking to a service station. Ethylene is not harmful or toxic to humans; however, at extremely high concentrations it is combu… As the metabolism of ethylene glycol progresses there will be less ethylene glycol and this will decrease the blood ethylene glycol concentration and the osmolal gap making this test less useful. If you’re a fruit ripener, then you are aware of the flammable properties of one of our routine tools: ethylene.
