- Environmental Bioconcentration: An estimated BCF of 3 was calculated in fish for erucic acid(SRC), using an estimated log Kow of 9.69(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 135,000 for the free acid(SRC), determined from a structure estimation method(2), indicates that undissociated erucic acid is expected to be immobile in soil(SRC). The estimated pKa of erucic acid is 4.7(3), indicating that this compound will almost entirely exist in the anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4). Volatilization from moist soil is not an important environmental fate process as the acid is in the anion form and anions do not volatilize. Erucic acid is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 1.2X10-6 mm Hg(SRC), determined from a fragment constant method(5). A 4.2-11% of the theoretical BOD using an activated sludge inoculum and the Warburg test (6), suggests that biodegradation may be an important environmental fate process in soil(SRC).

- Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 135,000 for the free acid(SRC), determined from a structure estimation method(2), indicates that undissociated erucic acid is expected to adsorb to suspended solids and sediment(SRC). The estimated pKa of 4.7(3) indicates erucic acid will exist almost entirely in the anion form at pH values of 5 to 9 and therefore volatilization from water surfaces is not expected to be an important fate process(4). According to a classification scheme(5), an estimated BCF of 3(SRC), from an estimated log Kow of 9.69(6) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). A 4.2-11% of the theoretical BOD using an activated sludge inoculum and the Warburg test (8), suggests that biodegradation may be an important environmental fate process in water(SRC).

- Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), erucic acid, which has an estimated vapor pressure of 1.2X10-6 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 cis- and trans-erucic acid are degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-lives for these reactions in air are estimated to be 4.7 and 4.3 hours(SRC), calculated from rate constants of 8.1X10-11 and 8.9X10-11 cu cm/molecule-sec at 25 °C(SRC) that were derived using a structure estimation method(3). Vapor-phase erucic acid is also degraded in the atmosphere by reaction with ozone(SRC); the half-life for cis-erucic acid and trans-erucic acid reactions in air are estimated to be 2.1 and 1.4 hours(SRC), respectively, calculated from rate constants of 1.3X10-16 and 2.0X10-16 cu cm/molecule-sec at 25 °C(SRC) that were derived using a structure estimation method(3). Particulate-phase erucic acid may be removed from the air by wet or dry deposition(SRC). Erucic acid does not contain chromopho Source: Hazardous Substances Data Bank (HSDB)
