- Environmental Bioconcentration: An estimated BCF of 2 was calculated for methyl palmitate (SRC) using a log Kow of 7.38(1) and a regression-derived equation developed for hydrophobic chemicals(2). According to a classification scheme(3), the estimated BCF suggests the potential for bioconcentration in aquatic organisms is low. Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 18,000(SRC), determined from a structure estimation method(2), indicates that methyl palmitate is expected to be immobile in soil(SRC). Volatilization of methyl palmitate from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 0.009 atm-cu m/mole(SRC), using a fragment constant estimation method(3). However, adsorption to soil is expected to attenuate volatilization(SRC). Methyl palmitate is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 0.00006 mm Hg(4). Methyl palmitate is expected to rapidly biodegrade in aerobic soils based on the results of screening studies(5). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 18,000(SRC), determined from an estimation method(2), indicates that methyl palmitate 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 0.009 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). Volatilization half-lives for a model river and model lake are 5 and 160 hours, respectively(SRC), using an estimation method(3). However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column(SRC). The volatilization half-life from a model pond is estimated to be about 60 hours ignoring adsorption; when considering maximum adsorption the volatilization half-life increases to 150 days(5). According to a classification scheme(6), an estimated BCF of 620(SRC) from a log Kow of 7.38(10) regression-derived equation(7) suggests the potential for bioconcentration in aquatic organisms is high. Methyl palmitate is expected to rapidly biodegrade in aerobic waters(8). An estimated base-catalyzed second-order 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 palmitate, which has a vapor pressure of 0.00006 mm Hg at 25 °C(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase methyl palmitate 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 20 hours(SRC) from its estimated rate constant of 1.9X10-11 cu cm/molecule-sec at 25 °C(3). Particulate-phase methyl palmitate may be removed from the air by wet and dry deposition(SRC). Source: Hazardous Substances Data Bank (HSDB)
