Ethylene glycol is a colorless, odorless, sweet-tasting chemical. At room temperature, ethylene oxide is a flammable colorless gas with a sweet odor. This page was last edited on 26 December 2020, at 15:11. Am J Med. for a 20 kg child. Caprolactam – removed from the list of hazardous air pollutants in June 1996 - Federal Register - June 18, 1996 (61 FR 30816). [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. Ethylene glycol is toxic and, if ingested, can cause fatal poisoning. [51][52][53][54] Human poisoning often occurs in isolated cases, but may also occur in epidemics. [2], Signs of ethylene glycol poisoning depend upon the time after ingestion. Ethylene glycol exposure can be extremely dangerous, with significant morbidity and mortality if … The U.S. Environmental Protection Agency generally puts substances which are lethal at more than 30 g to adults in Toxicity Class III. 1988 Jan;84(1):145-52. [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. 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 is not harmful or toxic to humans; however, at extremely high concentrations it is combu… [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. Ethylene glycol has a sweet taste and is often accidentally or intentionally ingested. It is the simplest alkene (a hydrocarbon with carbon-carbon double bonds).. Keeping pets and small children away from the area when draining the car radiator. [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. Treasure Island (FL): StatPearls Publishing; 2020 Jan. 2020 Jun 26. [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. [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. The diagnosis of ethylene glycol poisoning should be considered in any people with a severe acidosis. [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. [78], CS1 maint: DOI inactive as of December 2020 (. The presence of a large osmolal gap supports a diagnosis of ethylene glycol poisoning. [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. Epub 2014 Apr 9. If antifreeze is placed in toilets, ensuring the lid is down and the door closed. Repeated or prolonged exposure to the substance can produce targe t organs This depression appears similar to ethanol intoxication, but without the characteristic odor of alcohol. [24], In addition to antidotes, an important treatment for poisoning is the use of hemodialysis. [15], Ethylene glycol has been shown to be toxic to humans[16] and is also toxic to domestic pets such as cats and dogs. 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. Both these acids accumulate causing acidosis, which can lead to kidney problems and the formation of calcium oxalate (kidney stones). 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. In: StatPearls [Internet]. People therefore must be monitored in an intensive care unit. [50][51], Ethylene glycol poisoning is a relatively common occurrence worldwide. Trends in toxic alcohol exposures in the United States from 2000 to 2013: a focus on the use of antidotes and extracorporeal treatments. 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. The alleged exposure may be erroneous. 12). Ingestion of this liquid can lead to shock or even death. Even a small amount of this liquid can be harmful. The first to form is glycolic acid which is further oxidised to oxalic acid. [9] Other sources of ethylene glycol include windshield deicing agents, brake fluid, motor oil, developing solutions for hobby photographers, wood stains, solvents, and paints. 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. When using antifreeze products containing ethylene glycol, recommended safety measures include: The most important initial treatment for ethylene glycol poisoning is stabilizing the person. Because hemodialysis will also remove the antidotes from the blood, doses of antidotes need to be increased to compensate.
