  • Environmental Bioconcentration: An estimated BCF of 6 was calculated in fish for 3-heptanone(SRC), using a water solubility of 4,300 mg/L(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 44(SRC), determined from a water solubility of 4,300 mg/L(2) and a regression-derived equation(3), indicates that 3-heptanone is expected to have very high mobility in soil(SRC). Volatilization of 3-heptanone from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 9.1X10-5 atm-cu m/mole(SRC), derived from its vapor pressure, 2.6 mm Hg(4) and its water solubility(2). 3-Heptanone is expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(4). Biodegradation of 3-heptanone may be expected based upon screeening aqueous biodegradation tests(5). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 44(SRC), determined from a water solubility of 4,300 mg/L(2) and a regression-derived equation(3), indicates that 3-heptanone 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 9.1X10-5 atm-cu m/mole(SRC), derived from its vapor pressure, 2.6 mm Hg(4) and its water solubility(2). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 13 hours and 7.4 days, respectively(SRC). According to a classification scheme(5), an estimated BCF of 6(SRC), from its water solubility(2) and a regression-derived equation(3), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Biodegradation of 3-heptanone may be expected based upon screeening aqueous biodegradation tests(6). 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), 3-heptanone, which has a vapor pressure of 2.6 mm Hg at 20 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 3-heptanone 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 2 days(SRC), calculated from its rate constant of 7.9X10-12 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). 3-Heptanone contains chromophores that absorb at wavelengths >290 nm and therefore may be susceptible to direct photolysis by sunlight(4).
