- Environmental Bioconcentration: An estimated BCF of 72 was calculated for methyl n-octanoate(SRC), using an estimated log Kow of 3.32(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 moderate(SRC). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 1,500(SRC), determined from an estimated log Kow of 3.32(2,SRC) and a regression-derived equation(3), indicates that methyl n-octanoate is expected to have low mobility in soil(SRC). Volatilization of methyl n-octanoate from moist soil surfaces is expected to be an important fate process(SRC) given a Henry's Law constant of 7.83X10-4 atm-cu m/mole(4). Volatilization from dry soil surfaces is not expected to be an important fate process(SRC) based upon a vapor pressure of 0.54 mm Hg(5). Methyl n-octanoate was rapidly oxidized with an activated sludge inoculum(6), suggesting this compound will biodegrade in soil surfaces(SRC). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 1,500(SRC), determined from an estimated log Kow of 3.32(2,SRC) and a regression-derived equation(3), indicates that methyl n-octanoate is expected to adsorb to suspended solids and sediment in water(SRC). Volatilization from water surfaces is expected(3) based upon a Henry's Law constant of 7.83X10-4 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 hours and 5 days, respectively(SRC). A base-catalyzed second-order hydrolysis rate constant of 0.063 L/mole-sec(SRC) was estimated using a structure estimation method(5); this corresponds to half-lives of 3.3 years and 121 days at pH values of 7 and 8, respectively(5). Methyl n-octanoate was rapidly oxidized with an activated sludge inoculum(6), suggesting this compound will biodegrade in water surfaces(SRC). According to a classification scheme(7), an estimated BCF of 72(SRC), from its log Kow(2) and a regression-derived equation(8), suggests the potential for bioconcentration in aquatic organisms is moderate(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), methyl n-octanoate, which has a vapor pressure of 0.54 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase methyl n-octanoate 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 estimated rate constant of 7.1X10-12 cu cm/molecule-sec at 25 °C(3). Methyl n-octanoate may also undergo direct photolysis in the environment since this compound contains a functional group that can absorb UV light greater than 290 nm(4).
