Body Burden： Ethylbenzene was detected, not quantified, in 8 of 8 samples of mother's milk from 4 US urban areas(1). 16.5% of 387 expired air samples taken from 54 normal, healthy, urban volunteers were positive for ethylbenzene concentration with an average of 1.8 ng/L expired air(2). Whole blood samples from 250 subjects ranged in ethylbenzene concentrations from not detected to 59 ppb, with an average of 1.0 ppb(3). Blood samples from 251 humans in the US, collected as part of the 1999-2000 National Health and Nutrition Examination Survey, contained mean, median, minimum and maxium ethylbenzene concentrations of 0.073, 0.042, 0.010 and 0.949 ng/mL(4).

Fire Hazards： Highly flammable. Vapour/air mixtures are explosive.

Interactions： A study of workers exposed occupationally to solvent mixtures that include ethylbenzene (mean exposure level 1.8 ppm) showed a 58% incidence of hearing loss compared to 36% in the reference (unexposed) group. The role of ethylbenzene in the observed losses cannot be ascertained from this study given that ethylbenzene was only one of several solvents, most of which were present at mean concentrations 1.5- 3.5 times higher than ethylbenzene. Consistent with the outcome of occupational studies showing hearing loss, significant and persistent adverse auditory effects have been shown in animals after acute- and intermediate-duration inhalation exposures to ethylbenzene and after acute-duration oral exposures.

Safe Storage： Fireproof. Separated from strong oxidants. Provision to contain effluent from fire extinguishing. Store in an area without drain or sewer access.

Fire Fighting： Use dry powder, foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

Eye Prevention： Wear safety goggles.

Fire Potential： A very dangerous fire ... hazard when exposed to heat or flame ...

Health Effects： Chronic exposure to etylbenzene can lead to an increase in the mean number of lymphocytes and a decrease in hemoglobin levels. Acute duration and intermediate duration studies suggest that the auditory system is a sensitive target of ethylbenzene toxicity. Exposure ethylbenzene can lead to functional and organic disturbances (nervous system disturbances, toxic hepatitis and upper respiratory tract complaints). Metabolites of ethylbenzene have been shown to produce oxidative damage to DNA. (L311, T52)

Health Hazards： ERG2024, Guide 130 (Ethylbenzene): · Runoff from fire control or dilution water may cause environmental contamination.

Toxicity Summary： Changes in the integrity of the cell membrane after partitioning of ethylbenzene into the lipid bilayer may subsequently affect the function of membrane, particularly as a barrier and in energy transduction, and in the formation of a matrix for proteins and enzymes. Ethybenzene inhibits the activity of the astrocytic membrane ATPases, which helps regulate adequate intercellular levels of ions, nutrients, metabolic intermediates and precursors in the central nervous system. Thus, this may disturb the ability of the cells to maintain homeostasis. (L311, A186)

Soil Adsorption/Mobility： Measured ethylbenzene Koc values of 224(1), 240(2) and 257(3) have been reported. According to a classification scheme(4), these Koc values suggest that ethylbenzene is expected to have moderate mobility in soil. Sorption and desorption experiments demonstrated that the sorption process of ethylbenzene on marine sediments is reversible and that the sorption is even lower than expected from the log Kow data and the organic carbon content of the sediment(5); it was concluded that the marine sediment compartment is not an important sink for ethylbenzene(5). A soil leaching column study estimated an ethylbenzene Koc of 240 using a chromatographic methodology(6).

Environmental Biodegradation： ANAEROBIC: Anaerobic ethylbenzene transformation in Seal Beach Naval Weapons Station sediments in Southern California appeared to be strictly associated with nitrate-reducing processes(1). Ethylbenzene was completely degraded in microcosms inoculated with the sediment material from a refinery pond or activated sludge from the refinery treatment facility under nitrate-reducing conditions(2). At Sleeping Bear Dunes National Lakeshore in Michigan, ethylbenzene was degraded at slow rates via anaerobic degradation under ambient subsurface conditions using ferric iron, sulfate and/or carbon dioxide as the terminal electron acceptors(3). Ethylbenzene showed complete anaerobic oxidation in sediment-free iron-reducing enrichment cultures(4).

Volatilization from Water/Soil： The Henry's Law constant for ethylbenzene is 7.88X10-3 atm-cu m/mole(1). This Henry's Law constant indicates that ethylbenzene is expected to volatilize rapidly from water surfaces(2). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(2) is estimated as 3.1 hours(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(2) is estimated as 4.1 days(SRC). Ethylbenzene's Henry's Law constant(1) indicates that volatilization from moist soil surfaces may occur(SRC). Ethylbenzene is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 9.6 mm Hg(3).

Federal Drinking Water Guidelines： EPA 700 ug/L

Probable Routes of Human Exposure： NIOSH (NOES Survey 1981-1983) has statistically estimated that 201,833 workers (34,405 of these are female) are potentially exposed to ethylbenzene in the US(1). Occupational exposure to ethylbenzene may occur through inhalation and dermal contact with this compound at workplaces where ethylbenzene is produced or used. Monitoring data indicate that the general population may be exposed to ethylbenzene via inhalation of ambient air, ingestion of food and drinking water, and dermal contact with consumer products containing ethylbenzene(SRC). The general population can be exposed to ethylbenzene via inhalation especially in cities near many factories and heavily traveled highways and from air from burning gas, oil and coal(2). Ethylbenzene is infrequently detected in private and public gro...

Environmental Water Concentrations： RAIN/SNOW: Rain water collected in West Los Angeles, CA in March 1982 contained an ethylbenzene concentration of 9 ng/L(1). Ethylbenzene concentrations dissolved in rain from Portland, OR (collected between Feb-April 1984, 7 rain events) were 100% positive at 6.9-72 ng/L with a 34 ng/L avgerage(2). Snow and ice samples collected directly in cloud in 2005 and 2006 at Jungfraujoch, Germany contained mean ethylbenzene levels ranging from 74-285 ng/L(3).

Occupational Exposure Limits (OEL)： MAK (Maximale Arbeitsplatz Konzentration): 88 mg/m

Other Environmental Concentrations： Ethylbenzene has been detected in tobacco smoke, tobacco substitute smoke and in tobacco(1). The mean ethylbenzene concentration at premises in Spain allowing smoking, not-allowing smoking and general outdoor air was 2.3, 1.1 and 0.6 ug/cu m respectively(2). Mainstream cigarette smoke was found to contain an average ethylbenzene level of 4.4 ug/cigarette(3). Smoke from burning incense contained average ethylbenzene levels of 41.69-381.90 ug/cu m(4). Exposure assessment showed that the exposure to ethylbenzene from permanent pens ranged from 0 to 3.11 mg/kg/d (men) and 0 to 3.75 mg/kg/d (women)(5). Ethylbenzene was detected in the volatiles emitted from corn, alfalfa and cereal silage at concentrations of 0.02-0.13 ng/L(6).

Environmental Fate/Exposure Summary： Ethylbenzene's production and use as an intermediate for the manufacture of styrene and other chemicals, use as a resin solvent and use as a component of automotive and aviation fuels may result in its release to the environment through various waste streams. Ethylbenzene is emitted to air in exhaust from internal combustion engines and in tobacco smoke. It is a product of biomass combustion and a component of crude oil. If released to air, a vapor pressure of 9.6 mm Hg at 25 °C indicates ethylbenzene will exist solely as a vapor in the ambient atmosphere. Vapor-phase ethylbenzene will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals and nitrate radicals; the half-lives for these reactions in air is estimated to be 2.3 and 56 days, respectively....
