1,1,2,2-Tetrabromoethane's production and use as a solvent and metal separator, in microscopy(1), flotation agent(2), and as a mercury substitute in gauges and balances(3) may result in its release to the environment through various waste streams(SRC).

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 120(SRC), determined from a water solubility of 678 mg/l(3) and a regression-derived equation(4), indicates that 1,1,2,2-tetrabromoethane is expected to have high mobility in soil(SRC). Volatilization of 1,1,2,2-tetrabromoethane from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 1.34X10-5 atm-cu m/mole(SRC), derived from its vapor pressure, 0.02 mm Hg(2), and water solubility(3). The potential for volatilization of 1,1,2,2-tetrabromoethane from dry soil surfaces may exist(SRC) based upon its vapor pressure(2). 1,1,2,2-Tetrabromoethane, reached 29% of its theoretical BOD in 2 weeks using the Japanese MITI test(5), suggesting biodegradation in soil may be an important environmental fate process(SRC).|AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 120(SRC), determined from a water solubility of 678 mg/l(3) and a regression-derived equation(4), indicates that 1,1,2,2-tetrabromoethane is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(4) based upon an estimated Henry's Law constant of 1.34X10-5 atm-cu m/mole(SRC), derived from its vapor pressure, 0.02 mm Hg(2), and water solubility, 678 mg/l(3). Using this Henry's Law constant and an estimation method(4), volatilization half-lives for a model river and model lake are 5 and 43 days, respectively(SRC). However, hydrolysis half-lives of 20 and 2 hours at pH 7 and 8, respectively, have been calculated(5); therefore, under acidic or neutral conditions, hydrolysis will be the dominant removal process(SRC). According to a classification scheme(6), a BCF of <8.2(7), suggests that bioconcentration in aquatic organisms is low(SRC). A theoretical BOD of 29% was reported using an activated sludge inoculum at 30 mg/l and the Japanese MITI test over a 2 week test period(7), suggesting that biodegradation may occur in aquatic systems(SRC).|ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 1,1,2,2-tetrabromoethane, which has a vapor pressure of 0.02 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 1,1,2,2-tetrabromoethane 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 115 days(SRC), calculated from its rate constant of 1.4X10-13 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3).

The rate constant for the vapor-phase reaction of 1,1,2,2-tetrabromoethane with photochemically-produced hydroxyl radicals has been estimated as 1.4X10-13 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 115 days at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). Hydrolysis will be the dominant environmental fate process for 1,1,2,2-tetrabromoethane under neutral or basic conditions(3). A base-catalyzed second-order hydrolysis rate constant for this compound is 96.5 L/mole-sec(2); this corresponds to half-lives of 20 and 2 hours at pH values of 7 and 8, respectively(2).

5.50|BCF values of <8.2 and 0.5 to 7 were measured for 1,1,2,2-tetrabromoethane at compound concns of 1 ug/l and 10 ug/l, respectively(1). According to a classification scheme(2), these values BCF suggest that bioconcentration in aquatic organisms is low(SRC).

The Koc of 1,1,2,2-tetrabromoethane is estimated as 120(SRC), using a water solubility of 678 mg/l(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 1,1,2,2-tetrabromoethane is expected to have high mobility in soil(SRC).

The Henry's Law constant for 1,1,2,2-tetrabromoethane is estimated as 1.3X10-5 atm-cu m/mole(SRC) derived from its vapor pressure, 0.02 mm Hg(1), and water solubility, 678 mg/l(2). This Henry's Law constant indicates that 1,1,2,2-tetrabromoethane is expected to volatilize from water surfaces(3). 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)(3) is estimated as 5 days(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(3) is estimated as 43 days(SRC). 1,1,2,2-Tetrabromoethane's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of 1,1,2,2-tetrabromoethane from dry soil surfaces may exist(SRC) based upon its vapor pressure(1).

NIOSH (NOES Survey 1981-1983) has statistically estimated that 2,516 workers are potentially exposed to 1,1,2,2-tetrabromoethane in the US(1). Occupational exposure to 1,1,2,2-tetrabromoethane may occur through inhalation and dermal contact with this compound at workplaces where 1,1,2,2-tetrabromoethane is produced or used(SRC).

1,1,2,2-Tetrabromo[U-14C]ethane ([14C]TBE) was used to study the metabolism of TBE in rats. Three graded doses of TBE (1.17, 13.6, and 123 mg/kg; 1 microCi 14C/rat at each dose) were administered by gavage to three groups of four rats each. Excreta samples were collected at various time intervals up to 96 hr. Following euthanization, 14C activity was measured in the excreta, tissues, and carcass. The fraction of the dose exhaled as volatile metabolites of TBE, excluding 14CO2, was approximately 9-10% higher in rats given the high dose of TBE compared to that in rats given either the low or the medium dose. The fraction excreted in the urine decreased with increasing TBE dosage. 1,2-Dibromoethylene and tribromoethylene were identified as exhaled metabolites at the high dose. Three major urinary metabolites were identified: dibromoacetic acid, glyoxylic acid, and oxalic acid. The results of this study indicate that the metabolism of TBE was linear up to a dose of 13.6 mg/kg, but the contribution of various TBE metabolic pathways was different at a dose of 123 mg/kg.

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop. SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment. INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing. INGESTION: DO NOT INDUCE VOMITING. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. Be prepared to transport the victim to a hospital if advised by a physician. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital. (NTP, 1992)|(See procedures)
