  • NFPA Health Rating: 1 - Materials that, under emergency conditions, can cause significant irritation. Source: Hazardous Substances Data Bank (HSDB)
  • NFPA Fire Rating: 3 - Liquids and solids that can be ignited under almost all ambient temperature conditions. Materials produce hazardous atmospheres with air under almost all ambient temperatures or, though unaffected by ambient temperatures, are readily ignited under almost all conditions. Source: Hazardous Substances Data Bank (HSDB)
  • NFPA Instability Rating: 0 - Materials that in themselves are normally stable, even under fire conditions. Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Bioconcentration: An estimated BCF of 660 was calculated for 1-octene(SRC), using a log Kow of 4.57(1) 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 507(SRC), determined from a structure estimation method(2), indicates that 1-octene should have low to moderate mobility in soil(SRC). Volatilization of 1-octene from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 0.627 atm-cu m/mole(SRC) from its vapor pressure, 17.4 mm Hg(3), and water solubility, 4.1 mg/l(4). The potential for volatilization of 1-octene from dry soil surfaces may exist(SRC) based upon a vapor pressure of 17.4 mm Hg(3). However, adsorption to soil is expected to attenuate volatilization(SRC). Based on pure culture studies, 1-octene has the potential to biodegrade under aerobic conditions in soil(5,6). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 510(SRC), determined from an estimation method(2), indicates that 1-octene should 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 0.627 atm-cu m/mole(SRC) from its vapor pressure, 17.4 mm Hg(4), and water solubility, 4.1 mg/l(5). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 3.1 hours and 4.2 days, respectively(SRC). The volatilization half-life from a model pond 2 m deep is estimated to be 37 hrs ignoring adsorption; when considering maximum adsorption, the volatilization half-life increases to 95 hrs(6). According to a classification scheme(7), a BCF of 660(SRC) estimated from its log Kow of 4.57(8) and a regression-derived equation(9), suggests the potential for bioconcentration in aquatic organisms is high. Based on pure culture studies, 1-octene has the potential to biodegrade under aerobic conditions in water(10,11). 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-octene, which has a vapor pressure of 17.4 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 1-octene 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 3.9 hrs(SRC), calculated from its rate constant of 3.X10-11 cu cm/molecule-sec at 25 °C(3) determined using a structure estimation method(3). Vapor-phase 1-octene is also degraded in the atmosphere by reaction with ozone molecules(SRC); the half-life for this reaction in air is estimated to be 23 hrs(SRC), calculated from its rate constant of 1.2X10-17 cu cm/molecule-sec at 25 °C(3) determined using a structure estimation method(3).
