identify the EPA guidelines for ethylene glycol in drinking water. Measurement of serum ethylene glycol levels can confirm poisoning. An elevated serum level of ethylene glycol confirms ethylene glycol poisoning. Initial symptoms of ethylene glycol intoxication (0.5 to 12 hours after ingestion) are due to the direct toxicity of ethylene glycol. Wezorek C, Hodgman M, Dean B, Krenzelok E. Inadvertent ethylene glycol inhalation resulting in a toxic level. Numerous studies have documented that renal damage occurs after ethylene glycol ingestion without deposition of calcium oxalate crystals in the kidney (Vale 1979; Hall AH 1992). D. elevated serum ethylene glycol level. (Concise international chemical assessment document ; 45) 1.Ethylene glycol - toxicity 2.Ethylene glycol - adverse effects 3.Risk assessment 4.Environmental exposure 5.No-observed-adverse-effect level I.International Programme on Chemical Safety II.Series ISBN 92 4 153045 6 (NLM Classification: QD 305.A4) TIME COURSE: After ingestion, ethylene glycol is rapidly absorbed (within 1 to 4 hours) through the stomach.Following absorption, 80% or more of ethylene glycol is chemically converted by the body into toxic compounds. Most intoxications are associated with ingestion of antifreeze, which is typically 95% EG. CE Renewal Date: October 3, 2010 list three measurements that can assist with diagnosis of ethylene glycol poisoning. Only four significant conditions will cause metabolic acidosis and elevate both the anion and osmolal gaps. Several deaths are recorded annually in the U.S. alone. In such cases, the patient may initially develop an osmolal gap but will not immediately develop acidosis or an anion gap. Ethylene glycol is produced from ethylene (ethene), via the intermediate ethylene oxide.Ethylene oxide reacts with water to produce ethylene glycol according to the chemical … However, when large quantities of ethanol and ethylene glycol are ingested concurrently, metabolic acidosis may be inhibited or delayed. In one case report, a patient with an initial ethylene glycol level of 700 mg/dL was treated aggressively with fomepizole and was able to avoid dialysis. On admission, his blood ethylene glycol level was 1889 mg/dL, a potentially fatal level. Rosano et al. Ethylene glycol levels peak within 1-4 hours after consumption. Wills JH, Coulston F, Harris ES, McChesney EW, Russell JC, Serrone DM. Ethylene glycol is a type of alcohol found in automotive and household products. The presence of metabolic acidosis with both anion and osmolal gaps is an important clue to the diagnosis (Friedman, Greenberg et al. A. That corresponds to an osmolal shift of only 3 mOsm/L. The fate, effects, and potential environmental risks of ethylene glycol (EG) in the environment were examined. Ethylene glycol (C 2 H 4 (OH) 2) is a common household organic solvent and a main constituent of ‘antifreeze’ for car engines and hydraulic brake fluid.It is a colourless and odourless alcohol with a bittersweet taste and is second to ethanol as a cause of inadvertent lethal poisoning in the USA. A measured osmolality by the freezing point depression method is needed to detect an osmolal gap. Introduction. Ethylene glycol (EG) was orally administered to 27 cats at dose levels of 4, 6, or 8 ml/kg of body weight. In air, EG reacts with photo-chemically produced hydroxyl … Toxicity level is one of the primary differences between propylene glycol and ethylene glycol antifreeze. Note: Javascript is disabled or is not supported by your browser. The Alcohols/Ethylene Glycol Blood Level calculator provides antidote dosing for single, acute ingestions of ethanol, methanol, ethylene glycol, and isopropyl alcohol. C. The test confirms that the metabolic acidosis was due to ethylene glycol poisoning rather than another cause. Most laboratories routinely screen for unchanged ethylene glycol in suspected poisonings. While this should not be relief upon for ruling in or out the presence of ethylene glycol toxicity… J Med Toxicol. It is poisonous if swallowed. 1 Toxicity occurs after the ingestion of as little as 100 mL in an adult. CE Renewal Date: October 3, 2010 The Food and Drug Administration (FDA) has approved ethylene glycol as an indirect food additive, for use only as a component of adhesives used in packaging. OVERVIEW >1 mL/kg or a mouthful in a child is potentially lethal ethylene glycol itself is relatively non-toxic -> metabolites extremely toxic (glycolate) rate limiting step = alcohol dehydrogenase activity accumulation of glycolate -> direct cellular toxicity CLINICAL FEATURES drunk: automotive antifreeze, solvent, polish, paints, cosmetics, brake fluid, car wash fluid. Propylene glycol has a very low toxicity, which is why it is also found in cosmetics and personal care products, whereas ethylene glycol is poisonous and must be handled with caution to restrict any human or animal exposure. 2002). Course: WB 1103 CE Original Date: October 3, 2007 CE Renewal Date: October … A small osmolal gap may, however, represent a significant alcohol level. The serum anion gap (AG) is determined from serum electrolytes measured in mEq/L and may be defined by the formula: The serum osmolal gap (OG) is most commonly approximated by the formula: + [BAT (ethanol) divided by 4.6 (if present)]. 4. This is most accurate if the ethylene glycol level is between 50 to 100 mg/dL: Estimated ethylene glycol level = OG × 6.2. An elevated serum level of ethylene glycol confirms ethylene glycol poisoning; significant toxicity is associated with levels greater than 50 mg/dL. Often times we are left to make the decision to begin dialysis or therapy based upon a high degree of suspicion from the available laboratory data and patient circumstances. A. an elevated anion gap and an increased osmolal gap 1962; Parry and Wallach 1974; Szerlip 1999). An approximate lethal ethylene glycol dose in adults is approximately 100 cc (or) 1.4 mL/kg or 1.56g/kg. In applications where toxicity is NOT a concern, ethylene glycol is often the heat transfer fluid of choice. Wezorek C, Hodgman M, Dean B, Krenzelok E. Inadvertent ethylene glycol inhalation resulting in a toxic level. Some degree of altered mental status is usually the first sign of ethylene glycol intoxication. All animals are susceptible to ethylene glycol (EG) toxicity, but it is most common in dogs and cats. The Occupational Safety and Health Administration (OSHA) has not set a permissible exposure limit (PEL) for ethylene glycol 2 , OSHA did enact a ceiling limit of 125 mg/m 3 (50 ppm) in 1989, but that level, along with 375 others, was vacated for procedural reasons by the 11th Circuit Federal Court in 1993. C. calcium oxalate or hippurate crystalluria Ethylene glycol is poisonous. The government has developed regulations and guidelines for ethylene glycol. Upon ingestion, ethylene glycol is oxidized to glycolic acid, which is, in turn, oxidized to oxalic acid, which is toxic. Most ethylene glycol poisonings occur due to the ingestion of antifreeze. While this should not be relief upon for ruling in or out the presence of ethylene glycol toxicity, antifreeze contains fluorescein which can be easily seen under a Wood's lamp in present in vomit or the urine. D. None of the above. Wiley FH, Hueper WC, von Oettingen WF.The toxicity and potential dangers of ethylene glycol.J 3. An elevated serum level of ethylene glycol confirms ethylene glycol poisoning. J Tm'cd clin Tm-cot 1995;33:553. 2001; Wallace, Suchard et al. (1,4,5) Ethylene glycol is odorless. How do I view different file formats (PDF, DOC, PPT, MPEG) on this site? Massive ethylene glycol ingestion treated with fomepizole alone-a viable therapeutic option. CE Expiration Date: October 3, 2012 The Occupational Safety and Health Administration (OSHA) has not set a permissible exposure limit (PEL) for ethylene glycol 2 , OSHA did enact a ceiling limit of 125 mg/m, ACGIH recommends a ceiling exposure limit of 100 mg/m. It tastes sweet. Despite ingesting a lethal amount of ethylene glycol, the patient survived due to prompt medical attention and aggressive treatment using hemodialysis [30]. CE Original Date: October 3, 2007 D. None of the above. It does not have color or odor. Ethylene glycol intoxication is uncommon, but can result in life-threatening metabolic acidosis, kidney failure, and death. Conversely, failure to find an osmolal gap may lead to the erroneous assumption that no exogenous substances are present. In addition, by providing a MADL, this regulatory proposal may encourage businesses to lower the amount of the listed chemical in their products to a level that does not require a warning. Measuring glycolic acid in ethylene glycol poisonings has certain advantages, Yao and Porter (1996) were the first to develop a procedure for simultaneously determining ethylene glycol and its major toxic metabolite, glycolic acid. Diagnosing such poisoning can be problematic in the absence of a clear history of ingestion, especially in patients who present with altered mental status or those who deny such consumption. This value was The presence of calcium oxalate or hippurate crystals in the urine, together with an elevated anion gap or osmolal gap, strongly suggests ethylene glycol poisoning (Albertson 1999). A blood ethanol level will establish whether initial CNS symptoms may be due to ethanol. 20 mg/L (20 ppm) B. They also recommend that adults be exposed to no more than a daily total of 7 mg/L (7 ppm) for a lifetime. In suspected ethylene glycol toxicity time is of the essence. To review relevant content, see Glycolic Acid Analysis in this section. Ethylene glycol is a colorless, odorless, sweet-tasting chemical. Waiting 3-4 hours or more for the ethylene glycol level to come back can be deleterious to the patient. This test measures the level of ethylene glycol in the blood. Overview of Ethylene Glycol Toxicity. 2. It does not have color or odor. Numerous toxic substances are associated with an elevated anion gap (Table 2) (Goldfrank LR 1990). … Acetone causes an osmolal gap. Ethylene glycol exposure can be extremely dangerous, with significant morbidity and mortality if left untreated. Urinary crystals result from. The term “toxic alcohols” is a collective term that includes methanol, ethylene glycol, and isopropyl alcohol. EPA recommends that children be exposed to no more than 20 mg/L (20 ppm) ethylene glycol in drinking water for 1 day, or 6 mg/L (6 ppm) per day over 10 days. Waiting 3-4 hours or more for the ethylene glycol level to come back can be deleterious to the patient. A. EPA recommends that children be exposed to no more than 20 mg/L (20 ppm) ethylene glycol in drinking water for 1 day, or 6 mg/L (6 ppm) per day over 10 days. The presence of ethanol will also have a substantial impact on metabolism and therapy. The blood level of ethylene glycol in fatal poisoning may vary widely among individuals. 2001; Fraser 2002). As ethylene glycol is metabolized the osmol gap will decrease, but the anion gap will increase (unless fomepizole is used). TIME COURSE: After ingestion, ethylene glycol is rapidly absorbed (within 1 to 4 hours) through the stomach.Following absorption, 80% or more of ethylene glycol is chemically converted by the body into toxic compounds. D. Glycolic acid analysis is routinely performed in most laboratories. Serum lactate and betahydroxybutyrate levels may be indicated for an alcoholic patient, if alcoholic ketoacidosis is suspected (Meditext 2004). To review relevant content, see Environment in this section. It normally takes 3-6 hours to be excreted via urine, if the kidneys are not damaged by the toxicity caused by ethylene glycol. A normal osmolar gap can range from -14 to +10, and potentially toxic ethylene glycol ingestions can be hidden within an apparently normal osmolar … Letter to the Editor 111 REFERENCES 1. (Yao and Porter 1996; Porter, Rutter et al. It and its toxic byproducts first affect the central nervous system, then the heart, and finally the kidneys. Ethylene glycol is rapidly absorbed through the gastrointestinal tract after ingestion with serum concentrations peaking very soon after ingestion. (4) Ethylene glycol occurs as a clear, slightly viscous liquid that is completely miscible with water. They estimate the amount of ethylene glycol present in positive cases even though toxicity from ethylene glycol exposure is primarily caused by one metabolite—glycolic acid. To review relevant content, see Introduction in this section. Do not use ethylene glycol if there is the possibility of ingestion or … High-dose bolus exposure of rats to ethylene glycol (EG) causes developmental toxicity mediated by a metabolite, glycolic acid (GA), whose levels increase disproportionately when its metabolism is saturated. An elevated osmolal gap suggests the presence of a low-molecular weight substance. 15. 2010 Jun;6(2):131-4 full-text Boyer EW, Mejia M, Woolf A, Shannon M. Severe ethylene glycol ingestion treated without hemodialysis. Workplace. How do I view different file formats (PDF, DOC, PPT, MPEG) on this site? Findings correlate better with ethylene glycol toxicity than ethylene glycol levels. After a delay of 4 to 12 hours, metabolic acidosis gradually develops. The course of ethylene glycol toxicity … 2004; Purssell, Lynd et al. Because some antifreeze products contain fluorescein, the urine may fluoresce under a Wood's lamp (Winter, Ellis et al. Course: WB 1103 B. normochloremic metabolic acidosis However, because of the cost of fomepizole and the safety of hemodialysis, the threshold for this approach should be carefully considered on the basis of the clinical setting. Ethylene glycol toxicity is a type of toxic leukoencephalopathy. An ethylene glycol level (in mg/dL) may be estimated from the osmolal gap (OG) if it is the only osmotically active poison present and levels are taken early in the course. Letter to the Editor 111 REFERENCES 1. ... the acidosis has resolved and there are no signs of systemic toxicity or until the ethylene glycol level is undetectable. These are designed to protect the public from potential adverse health effects. 1990). 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. B. As ethylene glycol is metabolized the osmol gap will decrease, but the anion gap will increase (unless fomepizole is used). 2004). 16. It tastes sweet. A. For more information about this message, please visit this page: Agency for Toxic Substances & Disease Registry, Environmental Health and Medicine Education, Ethylene Glycol and Propylene Glycol Toxicity, Download Printer-Friendly version [PDF - 496 KB], Agency for Toxic Substances and Disease Registry, Renal failure, calcium oxalate and hippurate crystals, CNS depression, tachycardia, and tachypnea, Hemorrhagic tracheobronchitis and gastritis, identify the abnormal laboratory findings associated with ethylene glycol poisoning and. Patients who have both anion and osmolal gap should also have blood methanol tests. However, low-level exposures that do not saturate GA metabolism have a … Significant toxicity is often associated with levels greater than 25 milligrams per deciliter (mg/dL) (Hall AH 1992; Goldfrank LR 1998). The major danger is due to its sweet taste, which can attract children and animals. Abstract. Recent studies have demonstrated usefulness of glycolic acid analysis in ethylene glycol poisoning cases (Fraser 1998; Porter, Rutter et al. Caution must be used when interpreting the osmolal gap. *In this formula, osmolality (measured) is obtained by the freezing-point–depression method and expressed in milliosmoles per liter (mOsm/L); Na+ in mEq/L; BUN and glucose in mg/dL; blood alcohol test (BAT) in mg/dL. C. 200 mg/m3 Increased osmolal gap with a detectable serum ethylene glycol level … The ethylene glycol level was found to be 1889 mg/dL. Ethylene glycol is a type of alcohol found in automotive and household products. CNS effects predominate and include inebriation (without the alcohol odor on the breath), slurred speech, drowsiness, somnolence, hypotonia, hyporeflexia, ataxia, myoclonic jerks, and gastrointestinal upset. Ethylene Glycol (Anti-freeze) Toxicity • Ethylene glycol is a clear, odorless, sweet to the taste, highly hygroscopic synthetic • Liquid found commonly in automotive fluids – antifreeze, coolants, and brake … J Tm'cd clin Tm-cot 1995;33:553. The course of ethylene glycol toxicity is classically divided into three broad overlapping categories of adverse health effects. Lactic acidosis or propylene glycol intoxication also is capable of causing metabolic acidosis with osmolal gap. 2001; Sharma, O'Shaughnessy et al. The chemical formula for ethylene glycol is C 2 H 6 O 2, and its molecular weight is 62.07 g/mol. They also recommend that adults be exposed to no more than a daily total of 7 mg/L (7 ppm) for a lifetime (FSTRAC 1990). People sometimes drink ethylene glycol … CE Original Date: October 3, 2007 2. (3) The vapor pressure for ethylene glycol … Treatment was initiated 4 or 8 hours later and consisted of giving (intraperitoneal injection, IP) 5 ml of 20% ethanol in isotonic saline solution and 6 ml of 5% sodium bicarbonate in isotonic saline solution per kilogram of body weight. Ingestion of sufficient amounts is fatal if untreated. 5. EG undergoes rapid biodegradation in aerobic and anaerobic environments (approximately 100% removal of EG within 24 h to 28 days). Ethylene glycol may be swallowed accidentally, or it may be taken deliberately in a suicide attempt or as a substitute for drinking alcohol (ethanol). Wiley FH, Hueper WC, von Oettingen WF.The toxicity and potential dangers of ethylene glycol… The volume of distribution is about 0.7 L.kg. Findings determine how much ethylene glycol has metabolized to glycol acid. Symptoms of ethylene glycol toxicity include confusion, ataxia, hallucinations, … Reproductive Toxicity for Ethylene Glycol Monomethyl Ether June, 2004 Office of Environmental Health Hazard Assessment Reproductive and Cancer Hazard Assessment Section Summary The maximum allowable dose level (MADL) for ethylene glycol monomethyl ether (EGME) is 63 micrograms/day (µg/day) for the oral route of exposure. For this reason, some items on this page will be unavailable. Ethylene glycol, best known as a component of antifreeze, has been ingested both deliberately and accidentally, resulting in neurotoxicity and renal failure. Note: Javascript is disabled or is not supported by your browser. Buchanan JA, Alhelail M, Cetaruk EW, et al. Ethylene Glycol and Propylene Glycol Toxicity What Are the U.S. Standards for Ethylene Glycol Exposure Levels? Porter and colleagues published a modification of the method a few years later. These 95% commercial antifreeze preparations are diluted ~50% with water when used in vehicle cooling systems. If there simultaneously exists a blood ethyl alcohol level greater than 50-100 mg/dL, no metabolic acidosis will occur until the EtOH level falls. Previous studies have indicated that ethylene glycol (EG) is a developmental toxicant in rats and mice primarily when ingested. Select the Substance Ingested from the drop-down menu, and enter the Patient Weight, Amount Ingested , and Percent Solutions . For this reason, some items on this page will be unavailable. B. ACGIH recommends a ceiling exposure limit for ethylene glycol of Course: WB 1103 (Gastritis some times occurs early, as would symptoms caused by other substances in the case of a mixed ingestion). EPA recommends that, for a life-time ethylene glycol exposure of an adult, the limit should be no more than a daily total of Ethylene glycol is poisonous. Ethylene glycol : human health aspects. Significant toxicity is often associated with levels greater than 25 milligrams per deciliter (mg/dL) (Hall AH 1992; Goldfrank LR 1998). urinalysis (with special attention to crystalluria), the precipitation of calcium by the oxalic acid metabolite of ethylene glycol, the reaction of the glycine metabolite with benzoic acid, which forms hippuric acid, needles (most commonly) (Jacobsen, Hewlett, 2,3-butanediol, often found in the plasma of alcoholics, can be mistakenly identified as ethylene glycol when the analysis is performed by gas chromatography (Jones, Nilsson, Propylene glycol can also interfere with some ethylene glycol assays (Robinson, Scott, An inherited metabolic disorder can present as ethylene glycol intoxication from laboratory results (Pien, van Vlem, findings correlate better with ethylene glycol toxicity than ethylene glycol levels, findings determine how much ethylene glycol has metabolized to glycolic acid, the presence of glycolic acid objectively indicates toxicity, the test confirms that the metabolic acidosis was due to ethylene glycol poisoning rather than another cause (Fraser 2002), Ethylene glycol poisoning is strongly suggested by. For more information about this message, please visit this page: Agency for Toxic Substances & Disease Registry, Environmental Health and Medicine Education, Ethylene Glycol and Propylene Glycol Toxicity, Download Printer-Friendly version [PDF - 496 KB], Agency for Toxic Substances and Disease Registry, identify the ACGIH ceiling exposure limit for ethylene glycol, and. CE Expiration Date: October 3, 2012 Recent reviews argued that the use of the osmolal gap as a screening tool for ethylene glycol has significant limitations and remains hypothetical (Glaser 1996; Koga, Purssell et al. Ingestion of ethylene glycol (120 mg/kg body weight or 0.1 mL/kg body weight) can result in a toxic concentration. This study was designed to establish no-observed-effect levels (NOELs) for developmental toxicity of EG administered by gavage in both rodent species. The classic laboratory profile of ethylene glycol ingestion is an early osmolar gap (the ethylene glycol serves as an unmeasured osmole) that disappears as an anion gap metabolic acidosis develops (as the ethylene glycol is converted into its acidic derivatives). 1999). 50 mg/m3 Download Printer-Friendly version [PDF - 496 KB], After completing this section, you will be able to. This test measures the level of ethylene glycol in the blood. 100 mg/m3 Its toxicity is marked by psychological effects, such as altered mental status, and difficulty breathing Ethylene glycol produces CNS depression similar to that of ethanol. C. 7 mg/L (7 ppm) This in turn may reduce exposures to ethylene glycol and reduce resident, worker and environmental exposures to chemicals that cause reproductive toxicity. Ethylene glycol (C2H6O2) is a toxic alcohol that is found in various household and industrial agents. The main difference between propylene glycol and ethylene is the level of toxicity. Often times we are left to … Which of the following is the most reliable diagnostic index for suspected ethylene glycol ingestion? Results of these laboratory tests will confirm the presence and degree of metabolic acidosis and allow calculation of the anion and osmolal gaps (Figure 2). To review relevant content, see Key Points in this section. An ethylene glycol level >20 mg/dL is regarded as potentially toxic. People sometimes drink ethylene glycol by mistake or on purpose as a substitute for drinking alcohol. Communication with the laboratory is critical in poisoning cases for several reasons. Ethylene glycol is moderately toxic, with an oral LDLo = 786 mg/kg for humans. Absence of urinary crystals, however, does not rule out poisoning. Production Industrial routes. However, recent studies argued if Wood's lamp determination of urine fluorescence could be a reliable diagnostic test (Casavant, Shah et al. Download Printer-Friendly version [PDF - 496 KB], Upon completion of this section, you should be able to, All patients with known or suspected ethylene glycol ingestion require the following tests, Other helpful laboratory tests may include. In suspected ethylene glycol toxicity time is of the essence. Glycolic acid analysis has all of the following advantages EXCEPT Although an osmolal gap is often cited as indirect evidence of the presence of an exogenous alcohol or glycol, other substances or conditions may be causative. 6 mg/L (6 ppm) Approximately 100 cc ( or ) 1.4 mL/kg or 1.56g/kg measurements that can assist diagnosis!
