- Environmental Bioconcentration: An estimated BCF of 31 was calculated in fish for methyl jasmonate(SRC), using an estimated log Kow of 2.76(1) 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 150(SRC), determined from a structure estimation method(2), indicates that methyl jasmonate is expected to have high mobility in soil(SRC). Volatilization of methyl jasmonate from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 1.4X10-8 atm-cu m/mole(SRC), using a fragment constant estimation method(3). Methyl jasmonate is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 3.4X10-4 mm Hg at 25 °C(SRC), determined from a fragment constant method(2). Biodegradation data in soil were not available(SRC, 2013). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 150(SRC), determined from a structure estimation method(2), indicates that methyl jasmonate is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(3) based upon an estimated Henry's Law constant of 1.4X10-8 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). According to a classification scheme(5), an estimated BCF of 31(SRC), from an estimated log Kow of 2.76(6) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is moderate(SRC). Hydrolysis is not expected to be an important environmental fate process based on estimated hydrolysis half-lives of 12.3, 1,2 years and 44 days at pH values of 7,8 and 9, respectively(7). Biodegradation data in water were not available(SRC, 2013). 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 jasmonate, which has an estimated vapor pressure of 3.4X10-4 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase methyl jasmonate is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-lives for these reactions in air are estimated to be 2.1 and 3.1 hours for the cis- and trans-isomers, respectively(SRC), calculated from its rate constant of 7.4X10-12 (cis-) and 8.2X10-12 (trans-isomer) cu cm/molecule-sec at 25 °C(SRC) that were derived using a structure estimation method(3). The rate constant for the vapor-phase reaction of methyl jasmonate with ozone has been estimated as 1.3X10-16 (cis-isomer) and 2.0X10-16 (trans-isomer) cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(1). This corresponds to atmospheric half-lives of about 2.1 and 1.3 hrs, for the cis- and trans-isomers, respectively, at an atmospheric concentration of 7X10+11 ozone molecules per cu cm(4).
