- Summary: Under the conditions of these 2-year feed studies, there was no evidence of carcinogenic activity of ethylene glycol in male B6C3F1 mice receiving 6, 250, 12,500, or 25,000 ppm, or in female B6C3F1 mice receiving 12,500, 25,000, or 50,000 ppm. Administration of ethylene glycol resulted in hepatocellular hyaline degeneration in male mice fed diets containing 12,500 or 25,000 ppm and in female mice fed diets containing 50,000 ppm. An increased incidence of medial hyperplasia of small pulmonary arteries and arterioles occurred in female mice fed diets containing 12,500, 25,000, or 50,000 ppm ethylene glycol.

- Health Effects: Health effects of ethylene glycol poisoning include tachycardia, hypertension, hyperventilation, and metabolic acidosis.

- Toxicity Summary: IDENTIFICATION: Ethylene glycol is a colorless, odorless, sweet tasting, relatively non-volatile liquid and is completely soluble in water. This chemical has numerous uses, in manufacturing of polyethylene terephthalate, in natural gas processing, and as an antifreeze agent. HUMAN EXPOSURE: In humans ethylene glycol has induced only minimal dermal irritation, Nasal and or throat irritation were reported in a small number of subjects inhaling ethylene glycol, while higher concentrations caused eye irritation. Available data from acute poisoning cases indicate that the kidney is the critical organ for the toxicity of ethylene glycol. Available data are inadequate to assess the potential adverse neurological or immunological effects associated with long term exposure to ethylene glycol, although neurobehavioral and neurological disorders have been reported in cases of acute ethylene glycol poisonings in humans. In the limited number of investigations examined, neurological effects have not been observed at doses below those that have induced renal toxicity. ANIMAL STUDIES: Ethylene glycol has low acute toxicity in experimental animals following oral, inhalation and dermal exposure. Et Source: Hazardous Substances Data Bank (HSDB)
- Toxicity Summary: Ethylene glycol is metabolized by alcohol dehydrogenase to glycoaldehyde, which is then metabolized to glycolic, glyoxylic, and oxalic acids. These acids, along with excess lactic acid are responsible for the anion gap metabolic acidosis. Oxalic acid readily precipitates with calcium to form insoluble calcium oxalate crystals. Tissue injury is caused by widespread deposition of oxalate crystals and the toxic effects of glycolic and glyoxylic acids. Ethylene glycol produces central nervous system depression. The glycol probably causes the initial CNS depression; oxalate and the other intermediates seem to be responsible for nephrotoxicity. Glycoaldehyde and glyoxylate may be the principal metabolites responsible for EG nephrotoxicity and do so by causing ATP depletion and phospholipid and enzyme destruction. Glycine and acidosis, by-products of EG metabolism, can attenuate glyoxylate-mediated injury. This suggests that naturally occurring but incomplete protective pathways may be operative during the evolution of EG cytotoxicity. (A612, A613, A310) Source: Toxin and Toxin Target Database (T3DB)
- Environmental Bioconcentration: A BCF of 10 was reported for fish, Golden ide (Leuciscus idus melanotus), after 3 days of exposure(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC). A BCF of 190 after 1 day exposure was reported for algae (Chlorella fusca)(1). Crawfish were exposed to ethylene glycol at three concentrations (50 ug/mL, 200 ug/mL, and 1000 ug/mL) for 61 days and then transferred to clean water for 67 days; BCF values of 0.21 to 0.61 were recorded(3). Crawfish were able to completely eliminate the accumulated ethylene glycol within 5 days for animals exposed to 50 ug/mL and 6 days for those exposed to 200 and 1000 ug/mL ethylene glycol(3). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 0.2(SRC), determined from a structure estimation method(2), indicates that ethylene glycol is expected to have very high mobility in soil(SRC). Percent adsorption to 4 soils (two clay and two sandy clay soils) ranged from 0-0.5%(7). Volatilization of ethylene glycol from moist soil surfaces is not expected to be an important fate process(SRC) given a Henry's Law constant of 6.00X10-8 atm-cu m/mole(3). Ethylene glycol is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 0.0878 mm Hg at 25 °C(4). Ethylene glycol (100 ppm) added to Texas soil (sandy silt loam) was biodegraded 100% in 2 days; Mississippi soil (sandy loam) containing 100 ppm ethylene glycol showed 90, 95, and 97% biodegradation in 3, 4, and 12 days, respectively(5). Ethylene glycol at 100 ppm and 1000 ppm required 6 and 8 days, respectively, for complete biodegradation using a Mississippi soil inoculum(5). Biodegradation of aircraft deicing fluid components, containing ethylene glycol, was studied at 8 °C using a sandy loam soil collected from the side of an airport runway; corrected biodegradation rates Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 0.2(SRC), determined from a structure estimation method(2), indicates that ethylene glycol is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(3) based upon a Henry's Law constant of 6.00X10-8 atm-cu m/mole(4) According to a classification scheme(5), a BCF of 10 reported in fish (Golden ide (Leuciscus idus melanotus)) after 3 days exposure to ethylene glycol(6), suggests the potential for bioconcentration in aquatic organisms is low(SRC). In a river die-away test, degradation was complete within 3 days at 20 °C and 5-14 days at 8 °C(7), indicating that biodegradation in water is expected to be an important environmental fate process(SRC). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), ethylene glycol, which has a vapor pressure of 0.0878 mm Hg at 25 °C,(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase ethylene glycol is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 50 hours(SRC), calculated from its rate constant of 7.7X10-12 cu cm/molecule-sec at 25 °C(3). Ethylene glycol is not expected to be susceptible to direct photolysis by sunlight, since it does not contain functional groups that are expected to absorb light with wavelengths >290 nm(SRC).

Ethylene glycol has a sweet taste and is often ingested by accident or on purpose. Ethylene glycol breaks down into toxic compounds in the body. Ethylene glycol and its toxic byproducts first affect the central nervous system (CNS), then the heart, and finally the kidneys. Ingesting enough can cause death. Ethylene glycol is odorless.

- Uses: The major use of ethylene glycol is as a coolant or antifreeze in, for example, automobiles and personal computers. Ethylene glycol has become increasingly important in the plastics industry for the manufacture of polyester fibers and resins, including polyethylene terephthalate, which is used to make plastic bottles for soft drinks.
