Amendment to Section 25805, Maximum Allowable Dose Level (Oral) for Ethylene Glycol (Ingested) Notice of Proposed Rulemaking, Amendment to Section 25805, Specific Regulatory Levels: Chemicals Causing Reproductive Toxicity - Ethylene Glycol (Ingested) binding of oxalic acid and thus result in hypocalcemia. Ethylene glycol (C2H6O2 Ethylene glycol is an odorless, colorless, sweet-tasting syrupy substance with a molecular weight of 62.07, freezing point of -13°C and a boiling point of 197.6°C. These releases of ethylene glycol are expected to end up in surface water or groundwater. mL. evaluation of poisoning. People sometimes drink ethylene glycol by mistake or on purpose as a substitute for drinking alcohol. It is colorless, odorless, but has a sweet taste. industrial humectant, and hydraulic brake fluids, and as a glycerin substitute It tastes sweet. Immediate steps should be taken to limit its spread to the environment. It is also used in the manufacture of polyethylene terephthalate (PET) and in oil and gas processing. Death has been reported with ingestion of as little as 30 An internal standard solution was prepared with normal saline to contain 5 mg/dL (0.56 mmol/L) 1,2-butanediol. It does not have color or odor. Ethylene glycol levels peak within 1-4 hours after consumption. An approximate lethal ethylene glycol dose in adults is For enquiries, contact us. Early on in ethylene glycol ingestion the serum osmolality Summary Propylene glycol is a synthetic, colorless, odorless, tasteless liquid … Church AS et al. Ethylene glycol is a key ingredient in automotive antifreeze and coolant, to help keep a car’s engine from overheating and from freezing in the winter. Ethylene glycol is highly toxic to humans and is not used in food products. Ethylene glycol is a colorless, odorless, sweet-tasting chemical. The primary hazard is the threat to the environment. Ethylene glycol is a clear, colorless syrupy liquid. present with inebriation (intoxication). approximately 100 cc (or) 1.4 mL/kg or 1.56g/kg. Ethylene glycol is a type of alcohol found in automotive and household products. (2) Rats chronically exposed to ethylene glycol in their diet exhibited signs of kidney toxicity and liver effects. This is most accurate if the ethylene glycol level is between 50 to 100 mg/dL: Estimated ethylene glycol level = OG × 6.2. No hemodialysis: Less than 3 mmol/L then no further analysis necessary. One vital part is the use of Mono Ethylene Glycol (MEG). The Alcohols/Ethylene Glycol Blood Level calculator provides antidote dosing for single, acute ingestions of ethanol, methanol, ethylene glycol, and isopropyl alcohol. Comprehensive Point-of-Care Guide for Over 600 Lab Tests. Results of the final assessment indicate that ethylene glycol is not expected to remain in the environment for a long time or accumulate in organisms. The level of exposure depends upon the dose, duration, and work being done. However, Canadians are reminded when using any product, to carefully follow any safety warnings and directions. Laboratory testing in ethanol, methanol, Furthermore, the quantity of ethylene glycol that may be released to the environment is below the level expected to cause harm to organisms. The hydroxyl groups on glycols undergo the usual alcohol chemistry, giving a wide variety of possible derivatives. Blood levels of ethylene glycol are usually measured by head space gas chromatography either singly or in combination with other volatile compounds such as methanol, acetone, and isopropyl alcohol. This liquid is injected into the gas system at selected source points to prevent hydrate formation in the pipelines. Treatment of ethylene glycol and methanol toxicity is similar and is based on symptoms and serum level. Upon ingestion ethylene glycol (EG, monoethylene glycol) is rapidly absorbed from the gastrointestinal tract, and depending on the severity of exposure signs of toxicity may progress through three stages. PDR Lab Advisor. This chemistry permits ethylene glycol to act as an intermediate in a wide range of reactions. Canadians may be exposed to low levels of ethylene glycol through the use of consumer products containing ethylene glycol. This assessment addresses the potential for harm to the general population in Canada (not including workplace exposures). TCCs Ethylene Glycol (MEG) is a toxic, colorless, practically odorless, low-volatility, low-viscosity, hygroscopic liquid. The only effects were noted in a study of individuals exposed to low levels of ethylene glycol by inhalation for about a month were throat and upper respiratory tract irritation. conversion of the parent compound to toxic metabolites (glycoaldehyde, The Government of Canada has also concluded that ethylene glycol is not harmful to the health of the general population at current levels of exposure. J Emerg Med 1997;15:687-92. Ethylene Glycol Level, Toxic Alcohol Level. Cadent Gas has 82,000 miles of gas pipe to keep operational throughout the UK with 11 million homes and businesses connected. While Ethylene glycol is poisonous. The physical and chemical properties of ethylene glycol, also known as monoethylene glycol and 1,2-ethanediol, are presented in Table 1.Ethylene glycol is a clear, colourless, odourless, relatively non-volatile, viscous liquid (Nielsen et al. to 60 mL; however, survival has been reported with ingestion of more than 3,000 Death has been reported with ingestion of as little as 30 In December 2000, the assessment of ethylene glycol was temporarily suspended to allow government scientists more time to address the data gaps, identified during the assessment period, that were related to the human health effects of ethylene glycol and how Canadians are exposed to this chemical. Hemodialysis is the most effective form of treatment for an acidotic patient/victim and may be used when the blood ethylene glycol level is greater than 50 mg/dL, with severe metabolic or fluid abnormalities despite other therapeutic interventions, or in cases of kidney failure. Most releases of ethylene glycol to the environment are expected to occur from aircraft de-icing/anti-icing operations. in commercial products such as paints, lacquers, detergents, and cosmetics. You will not receive a reply. Typically a 50 per cent concentration of glycol will give you freeze protection down to -30F/-34C. Ethylene glycol is used in many industries. under a Wood's lamp in present in vomit or the urine. Long term outcomes may include kidney failure and brain damage. plasma or draw serum blood sample. For example, water is 80, ethylene glycol 37, and ethanol 24.3. All glycol manufacturers provide charts (see Figure 1), which show the percentage of glycol required to provide a certain level of protection against freezing or burst protection. converted to glycolic acid, glyoxylic acid, and oxalic acid and cause an Toxic metabolites of EG cause severe metabolic acidosis and renal tubular epithelial damage. It is most commonly encountered as automotive antifreeze.Diethylene glycol behaves similarly to ethylene glycol in an overdose. Ethylene glycol is not presently a concern for the environment or human health at current levels of exposure. Public Notices Related to this Chemical. Ethylene glycol level may be undetectable due to Ethylene glycol enzyme reaction reagents were obtained from Catachem. An estimated lethal oral ethylene glycol dose is 1.4 mL/kg Lethal Concentration: An approximate lethal ethylene glycol dose in adults is approximately 100 cc; however, individuals reportedly have survived much higher doses. Canadians who handle this substance in the workplace should consult with their occupational health and safety representative about safe handling practices, applicable laws and requirements under the. Overview. It is completely miscible with water and many organic liquids. Ethylene glycol is moderately toxic, with an oral LDLo = 786 mg/kg for humans. Ethylene A the osmolar gap and multiple by 6.2. The Government of Canada has therefore concluded that ethylene glycol is not entering the environment in a quantity or under conditions that constitute a danger to the environment. Based on handling practices currently in place, such releases should be low. Several deaths are recorded annually in the U.S. alone. First ed. Ethylene glycol is manufactured in and imported into Canada. An ethylene glycol level >20 mg/dL is regarded as potentially toxic. The essential information needed to complete the assessment was identified and acquired during subsequent years, and has been incorporated into the final updated assessment report. Since it is a liquid it can easily penetrate the soil and contaminate groundwater and nearby streams. Workers may be harmed from exposure to ethylene glycol. The mainstay of treatment is inhibition of the alcohol dehydrogenase enzyme, to minimize the formation of toxic metabolites, while the relatively nontoxic parent alcohol is eliminated renally. 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). Ethylene glycol poisoning is poisoning caused by drinking ethylene glycol. and osmolar gap will be high, but will decrease as the ethylene glycol gets Toxicity and death may occur after drinking even a small amount. This test measures the level of ethylene glycol in the blood. It normally takes 3-6 hours to be excreted via urine, if the kidneys are not damaged by the toxicity caused by ethylene glycol. 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 … Releases of ethylene glycol to outdoor and indoor air may also occur from manufacturing and processing facilities and from use of consumer products. Upon ingestion, ethylene glycol is oxidized to glycolic acid, which is, in turn, oxidized to oxalic acid, which is toxic. Measurement of ethylene glycol in serum or plasma for the An estimated lethal oral ethylene glycol dose is 1.4 mL/kg or 1.56g/kg. made while waiting on the official level to come back from the lab by taking Dip the strip in the test substance to indicate the boiling point, freezing point and PH. [31] reviewed 12 medical examiners’ cases in which fatality was due to ethylene glycol poisoning and observed that the ethylene glycol concentrations ranged widely from 5.8 to … In addition, there are some enzymatic methods available for rapid determination of blood ethylene glycol levels using an automated analyzer in the clinical laboratory. Ingestion of sufficient amounts is fatal if untreated. It can also be used in a variety of other products such as floor and wall adhesives, brake fluid, automotive wax/polish and floor wax/polish, in caulks and grout, concrete sealers and shoe polish. Ethylene Glycol Market Country Level … Chemical substances fact sheets and frequently asked questions, State of the Science Report for Ethylene Glycol, Workplace Hazardous Materials Information System. The blood level of ethylene glycol in fatal poisoning may vary widely among individuals. Ethylene glycol may be swallowed accidentally, or it may be taken deliberately in a suicide attempt or as a substitute for drinking alcohol (ethanol). The major danger is due to its sweet taste, which can attract children and animals. Ethylene glycol is present as a slow-evaporating solvent and/or freeze-thaw stabilizer in latex paints. An approximate lethal ethylene glycol dose in adults is The symptoms of toxicity appear, if more than 250 mg/L is ingested, and 100 mL is enough to kill an adult. approximately 100 cc; however, individuals reportedly have survived much higher Approximately 50% of ingested EG is excreted unchanged by the kidneys; however, a series of oxidation reactions in the liver and kidneys metabolize the remaining EG. Ethylene glycol is used as a solvent, in antifreeze, increase in the anion gap as well as metabolic acidosis. 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. Neurological effects characterize the first step consisting of central nervous depression (intoxication, lethargy, seizures, and coma). Select the Substance Ingested from the drop-down menu, and enter the Patient Weight, Amount Ingested , and Percent Solutions . 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. Ethylene Glycol and Methanol CH30-002A01 Rev 1.00 Page 1 of 2 GTS Proven Ethylene Glycol (EG) Ingestion (Refer to Appendix 1) The following protocol assumes that one initial EG level has been performed. Both the U.S. military and the U.S. postal service have used … LaGow B et al., eds. On the basis of type, the ethylene glycol market is segmented into Monoethylene Glycol (MEG), Di-Ethylene Glycol (DEG) and Tri-Ethylene Glycol (TEG). The Government of Canada has conducted an evaluation of ethylene glycol, and published the results in a final assessment report. Step 1 Use CoolTrak coolant test strips (kimdon.com) to test a sample of ethylene or propylene glycol based coolants. EG is rapidly absorbed from the GI tract; in dogs, blood concentrations of EG peak within 3 hr of ingestion. Ethylene glycol can cause death if swallowed. Ethylene glycol is a solvent found in products ranging from antifreeze fluid and de-icing solutions to carpet and fabric cleaners. Later symptoms may include a decreased level of consciousness, headache, and seizures. Ethylene glycol is more polar than ethanol - a rough measure of polarity is given by the dielectric constant. mL/kg body weight) can result in a toxic concentration. doses. Montvale, NJ: Thomson PDR; 2007. An estimation of the ethylene glycol concentration can be The final assessment report was published on April 17, 2010. Early symptoms include intoxication, vomiting and abdominal pain. It and its toxic byproducts first affect the central nervous system, then the heart, and finally the kidneys. higher lactic acid levels than actually present. 1,2-dihydroxyethane, 1,2-ethanediol, 1,2ethanediol, 2-hydroxyethanol, ethane-1,2-diol, ethylene glycol, and glycol Cancer Cancer: Ingredients linked to cancer in government, industry or academic studies or … ethylene glycol, and isopropanol toxicities. Ethylene glycol, propylene glycol, and 1,2-butanediol (internal standard for the GC-FID assay) were purchased from Sigma Aldrich (St Louis, MO). Mono Ethylene Glycol (MEG) Level Monitoring. glycol can interact with the assays that measure lactic acid, thereby causing to 60 mL; however, survival has been reported with ingestion of more than 3,000 1993).It has a sweet taste and imparts a warming sensation to the tongue when swallowed (Beasley and Buck 1980). Collect Based on the conclusion of the final assessment, no further action will be taken on ethylene glycol at this time. Especially significant is resin formation, including the condensation with dimethyl terephthalate or terephthalic acid resulting in … The health risks associated with a chemical depend on the hazard (its potential to cause health effects) and the dose (the amount of chemical to which you are exposed). Ethylene glycol is a major component of deicing solutions used in a variety of transportation applications, including cars, boats and aircraft, as well as on airport runways during the cold winter months. Suspected ethylene glycol poisoning. Similar to alcohol (ethyl alcohol) ingestion, patients can Ingestion of ethylene glycol (120 mg/kg body weight or 0.1 Based on application, the market is segmented into polyester fiber and films, PET, antifreeze and coolant and others. It can also be used in a variety of other products such as floor and wall adhesives, brake fluid, automotive wax/polish and floor wax/polish, in caulks and grout, concrete sealers and shoe polish. glycol toxicity, antifreeze contains fluorescein, which can be easily seen Most ethylene glycol poisonings occur due to the ingestion of antifreeze. Don't forget to monitor for calcium levels as it can decrease due to Rosano et al . or 1.56g/kg. Ethylene glycol is primarily used as a component of de-icer and anti-icer/anti-freeze fluid used in aircraft de-icing and anti-icing operations, and as an anti-freeze component in motor vehicles. mL. It is poisonous if swallowed. Ethylene glycol is an industrial chemical. Ethylene glycol has an elimination half-life of 3-9 hours but if alcohol dehydrogenase is interrupted either by fomepizole or ethanol (level 11-22 mmol/L or 50-100 mg/dL) thereby inhibiting the conversion of ethylene glycol to glycoaldehyde the elimination half … That corresponds to an osmolal shift of only 3 mOsm/L. this should not be relief upon for ruling in or out the presence of ethylene In addition to blood levels of ethylene glycol, hypocalcemia, elevated anion gap, metabolic acidosis, and osmolal gap elevation are observed.
