Ethylene glycol is present as a slow-evaporating solvent and/or freeze-thaw stabilizer in latex paints. Neurological effects characterize the first step consisting of central nervous depression (intoxication, lethargy, seizures, and coma). The Government of Canada has conducted an evaluation of ethylene glycol, and published the results in a final assessment report. ethylene glycol, and isopropanol toxicities. An internal standard solution was prepared with normal saline to contain 5 mg/dL (0.56 mmol/L) 1,2-butanediol. 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. Laboratory testing in ethanol, methanol, The hydroxyl groups on glycols undergo the usual alcohol chemistry, giving a wide variety of possible derivatives. Ethylene glycol is a clear, colorless syrupy liquid. Ethylene glycol is moderately toxic, with an oral LDLo = 786 mg/kg for humans. Ingestion of sufficient amounts is fatal if untreated. Most releases of ethylene glycol to the environment are expected to occur from aircraft de-icing/anti-icing operations. glycol toxicity, antifreeze contains fluorescein, which can be easily seen 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. 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. mL. 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 … This test measures the level of ethylene glycol in the blood. Ethylene glycol poisoning is poisoning caused by drinking ethylene glycol. The final assessment report was published on April 17, 2010. Both the U.S. military and the U.S. postal service have used … This liquid is injected into the gas system at selected source points to prevent hydrate formation in the pipelines. 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. Long term outcomes may include kidney failure and brain damage. 1993).It has a sweet taste and imparts a warming sensation to the tongue when swallowed (Beasley and Buck 1980). to 60 mL; however, survival has been reported with ingestion of more than 3,000 Measurement of ethylene glycol in serum or plasma for the 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. Furthermore, the quantity of ethylene glycol that may be released to the environment is below the level expected to cause harm to organisms. It is completely miscible with water and many organic liquids. That corresponds to an osmolal shift of only 3 mOsm/L. For example, water is 80, ethylene glycol 37, and ethanol 24.3. Early on in ethylene glycol ingestion the serum osmolality Comprehensive Point-of-Care Guide for Over 600 Lab Tests. doses. This chemistry permits ethylene glycol to act as an intermediate in a wide range of reactions. Ethylene Glycol Market Country Level … 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. TCCs Ethylene Glycol (MEG) is a toxic, colorless, practically odorless, low-volatility, low-viscosity, hygroscopic liquid. People sometimes drink ethylene glycol by mistake or on purpose as a substitute for drinking alcohol. The symptoms of toxicity appear, if more than 250 mg/L is ingested, and 100 mL is enough to kill an adult. This assessment addresses the potential for harm to the general population in Canada (not including workplace exposures). binding of oxalic acid and thus result in hypocalcemia. Several deaths are recorded annually in the U.S. alone. An estimated lethal oral ethylene glycol dose is 1.4 mL/kg or 1.56g/kg. Toxicity and death may occur after drinking even a small amount. 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. This is most accurate if the ethylene glycol level is between 50 to 100 mg/dL: Estimated ethylene glycol level = OG × 6.2. An estimation of the ethylene glycol concentration can be under a Wood's lamp in present in vomit or the urine. Ethylene glycol level may be undetectable due to conversion of the parent compound to toxic metabolites (glycoaldehyde, plasma or draw serum blood sample. Treatment of ethylene glycol and methanol toxicity is similar and is based on symptoms and serum level. An approximate lethal ethylene glycol dose in adults is present with inebriation (intoxication). glycol can interact with the assays that measure lactic acid, thereby causing It is colorless, odorless, but has a sweet taste. higher lactic acid levels than actually present. Ethylene evaluation of poisoning. 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. Summary Propylene glycol is a synthetic, colorless, odorless, tasteless liquid … the osmolar gap and multiple by 6.2. 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. Mono Ethylene Glycol (MEG) Level Monitoring.
