  • Environmental Bioconcentration: An estimated BCF of 310 was calculated for 1-dodecene(SRC), using an estimated log Kow of 6.10(1,SRC) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is high. Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 5900(SRC), determined from a structure estimation method(2), indicates that 1-dodecene is expected to be immobile in soil. Volatilization of 1-dodecene from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 4.25 atm-cu m/mole(SRC), using a fragment constant estimation method(3). 1-Dodecene is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 0.0159 mm Hg(4). However, adsorption to soil is expected to attenuate volatilization. Pure culture studies indicate that 1-dodecene has the potential to biodegrade under aerobic conditions in soil(5-7), but the rate of biodegradation in soil is unknown(SRC).

  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 5900(SRC), determined from an estimation method(2), indicates that 1-dodecene is expected to adsorb to suspended solids and sediment in water(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 4.25 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 1.3 hr and 120 hr, respectively, but these rates are expected to be attenuated by adsorption(SRC). The half-life for volatilization from a model pond, which takes into account adsorptive processes, is 17 months(8,SRC). According to a classification scheme(5), an estimated BCF of 310(SRC), from an estimated log Kow of 6.10(6) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is high. Pure culture studies indicate that 1-dodecene has the potential to biodegrade under aerobic conditions in water(9-11), but the rate of biodegradation is unknown. 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), 1-dodecene, which has a vapor pressure of 0.0159 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 1-dodecene 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 9.961 hr(SRC), calculated from its rate constant of 39X10-12 cu cm/molecule-sec at 25 °C(3) determined using a structure estimation method(3).
