1,2-Dibromoethylene's production and use as a research chemical(1) may result in its release to the environment through various waste streams(SRC).

Atmospheric Fate: 1,2-Dibromoethylene does not absorb sunlight at the wavelengths available in the troposphere, so direct photolysis is not expected.|TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 29(SRC), determined from a water solubility of 8,910 mg/l(2) and a regression-derived equation(3), indicates that 1,2-dibromoethylene is expected to have very high mobility in soil(SRC). Volatilization of 1,2-dibromoethylene from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 8.5X10-4 atm-cu m/mole(SRC), derived from its vapor pressure, 31 mm Hg(4), and water solubility, 8,910 mg/l(2). The potential for volatilization of 1,2-dibromoethylene from dry soil surfaces may exist(SRC) based upon a vapor pressure of 31 mm Hg(4).|AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 29(SRC), determined from a water solubility of 8,910 mg/l(2) and a regression-derived equation(3), indicates that 1,2-dibromoethylene is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 8.5X10-4 atm-cu m/mole(SRC), derived from its vapor pressure, 31 mm Hg(4), and water solubility, 8,910 mg/l(2). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 2.3 and 140 hours, respectively(SRC). According to a classification scheme(5), an estimated BCF of 4(SRC), determined from a water solubility(2) and a regression-derived equation(3), suggests the potential for bioconcentration in aquatic organisms is low(SRC).|ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 1,2-dibromoethylene, which has a vapor pressure of 31 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 1,2-dibromoethylene is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals and ozone molecules(SRC). The half-life for the reaction in air with hydroxyl radicals is estimated to be to be 2.8 days for the cis-isomer and 2.5 days for the trans-isomer of 1,2-dibromoethylene(SRC), calculated from their rate constants of 3.8X10-12 and 4.3X10-12 cu cm/molecule-sec at 25 °C(SRC), respectively, determined using a structure estimation method(3). The half-life for the reaction in air with ozone molecules is estimated to be 670 days for the cis-isomer and 330 days for the trans-isomer of 1,2-dibromoethylene(SRC), calculated from their rate constants of 1.7X10-20 and 3.4X10-20 cu cm/molecule-sec at 25 °C(SRC), respectively, determined using a structure estimation method(3).

... In the troposphere, /1,2-dibromoethylene/ should react with hydroxyl radicals and ozone fairly rapidly. Thus, the rate of atmospheric decomposition will depend upon the concentrations of hydroxyl radicals and ozone.|The rate constants for the vapor-phase reaction of 1,2-dibromoethylene with photochemically-produced hydroxyl radicals have been estimated as 3.8X10-12 cu cm/molecule-sec for the cis-isomer and 4.3X10-12 cu cm/molecule-sec for the trans-isomer at 25 °C(SRC), using a structure estimation method(1). This corresponds to atmospheric half-lives of about 2.8 and 2.5 days at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1) for the cis- and trans-isomers, respectively. 1,2-Dibromoethylene is not expected to undergo hydrolysis in the environment due to the lack of hydrolyzable functional groups(2) nor to directly photolyze due to the lack of absorption in the environmental UV spectrum (>290 nm).

An estimated BCF of 4 was calculated for 1,2-dibromoethylene(SRC), using a water solubility(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

44.67 L/kg|The Koc of 1,2-dibromoethylene is estimated as 29(SRC), using a water solubility of 8,910 mg/l(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 1,2-dibromoethylene is expected to have very high mobility in soil.

The Henry's Law constant for 1,2-dibromoethylene is estimated as 8.5X10-4 atm-cu m/mole(SRC), derived from its vapor pressure, 31 mm Hg(1), and water solubility, 8,910 mg/l(2). This Henry's Law constant indicates that 1,2-dibromoethylene 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 2.3 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)(3) is estimated as 140 hours(SRC). 1,2-Dibromoethylene's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of 1,2-dibromoethylene from dry soil surfaces may exist(SRC) based upon a vapor pressure of 31 mm Hg(1).

Since 1,2-dibromoethylene is only used as a research chemical, occupational exposure to 1,2-dibromoethylene may occur through inhalation and dermal contact with this compound at chemical research facilities where 1,2-dibromoethylene is produced or used. (SRC)
