  • Environmental Bioconcentration: An estimated BCF of 21 was calculated for 1-heptanol(SRC), using a log Kow of 2.62(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). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 74(SRC), determined from a water solubility of 1670 mg/L(2) and a regression-derived equation(3), indicates that 1-heptanol is expected to have high mobility in soil(SRC). Volatilization of 1-heptanol from moist soil surfaces is expected to be an important fate process(SRC) given a Henry's Law constant of 1.88X10-5 atm-cu m/mole(4). 1-Heptanol is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 0.216 mm Hg(5). 1-Heptanol has been demonstrated to be readily biodegradable in aerobic screening tests(6-10) and therefore should biodegrade in soil(SRC).

  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 74(SRC), determined from a water solubility of 1670 mg/L(2) and a regression-derived equation(3), indicates that 1-heptanol is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon a Henry's Law constant of 1.88X10-5 atm-cu m/mole(4). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 2.2 days and 20 days, respectively(SRC). According to a classification scheme(5), an estimated BCF of 21(SRC), from its log Kow of 2.62(6) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). 1-Heptanol has been demonstrated to be readily biodegradable in aerobic screening tests(8-12) and therefore should biodegrade in water(SRC). 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-heptanol, which has a vapor pressure of 0.216 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 1-heptanol 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 28 hours(SRC), calculated from its rate constant of 1.36X10-11 cu cm/molecule-sec at 25 °C(3).
