- Environmental Bioconcentration: An estimated BCF of 3.2 was calculated in fish for ferulic acid, using a measured log Kow of 1.51 (1) and a regression-derived equation (2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organism is low(SRC), provided the compound is not metabolized by the organism(SRC). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 57(SRC), determined from a log Kow of 1.51(2) and a regression-derived equation(3), indicates that ferulic acid is expected to have high mobility in soil(SRC). The pKa of ferulic acid is 4.58(4), indicating that this compound will almost entirely exist in the anion form. In the environment, anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5). Volatilization of ferulic acid from moist soil surfaces is not expected to be an important fate process(SRC) given the anionic nature of ferulic acid in the environment. Ferulic acid is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 2.7X10-6 mm Hg(SRC), determined from a fragment constant method(6). Under neutral and acidic conditions in soil, ferulic acid is expected to undergo rapid aerobic biodegradation(7)(8). Under alkaline conditions in soil, ferulic acid is not expected to undergo rapid aerobic biodegradation(8). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 57(SRC), determined from a log Kow of 1.51(2) and a regression-derived equation(3), indicates that ferulic acid is not expected to adsorb to suspended solids and sediment(SRC). A pKa of 4.58(4) indicates ferulic acid will exist almost entirely in the anion form at pH values of 5 to 9, and therefore volatilization from water surfaces/moist soil is not expected to be an important fate process(5). According to a classification scheme(6), an estimated BCF of 3.2(SRC), from its log Kow of 1.51(2) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Ferulic acid is expected to biodegrade rapidly in water under anaerobic conditions(8). 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), ferulic acid, which has a an estimated vapor pressure of 2.7X10-6 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), will exist in both the vapor and particulate phases. Vapor-phase ferulic acid 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 8 hours(SRC), calculated from its rate constant of 4.8X10-11 cu cm/molecule-sec at 25 °C(SRC), derived using a structure estimation method(3). Particulate-phase ferulic acid may be removed from the air by wet or dry deposition(SRC). Ferulic acid contains a chromophore that absorbs light at wavelengths >290 nm(4) and therefore may be susceptible to direct photolysis by sunlight(SRC). Source: Hazardous Substances Data Bank (HSDB)
