- Environmental Bioconcentration: An estimated BCF of 86 was calculated for 1-undecanol(SRC), using a log Kow of 4.72(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), 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 8,800(SRC), determined from a log Kow of 4.72(2) and a regression-derived equation(3), indicates that 1-undecanol is expected to be immobile in soil(SRC). Volatilization of 1-undecanol from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 7.3X10-5 atm-cu m/mole(SRC), using a fragment constant estimation method(4). However, adsorption to soil is expected to attenuate volatilization(SRC). 1-Undecanol is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 2.97X10-3 mm Hg(5). The theoretical BOD for 1-undecanol was 27.6% after 5-day incubation in sewage(6), indicating that biodegradation may be an important environmental fate process in soil(SRC). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 8,800(SRC), determined from a log Kow of 4.72(2) and a regression-derived equation(3), indicates that 1-undecanol is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 7.3X10-5 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 20 hours and 10 days, respectively(SRC). However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column. The estimated volatilization half-life from a model pond is 9 months if adsorption is considered(5). According to a classification scheme(6), an estimated BCF of 86(SRC), from its log Kow(2) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is moderate(SRC). The theoretical BOD for 1-undecanol was 27.6% after 5-day incubation in sewage(8), indicating that biodegradation may be an important environment 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), 1-undecanol, which has a vapor pressure of 2.97X10-3 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 1-undecanol 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 23 hours(SRC), calculated from its rate constant of 1.7X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3).
