- Environmental Bioconcentration: An estimated BCF value of 2.8X10+4 was calculated for 1-octadecanol(SRC), using an experimental water solubility of 1.1X10-3 mg/L at 25 °C(1) and a recommended regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is very high(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 1.8X10+5(SRC), determined from a water solubility of 1.1X10-3 mg/L(2) and a regression-derived equation(3), indicates that 1-octadecanol is expected to be immobile in soil(SRC). Volatilization of 1-octadecanol from moist soil surfaces may be expected to be an important fate process(SRC) given an estimated Henry's Law constant of 8.41X10-4 atm-cu m/mole(SRC), derived from a vapor pressure of 2.7X10-6 mm Hg at 25 °C(4), and its water solubility(2). However, adsorption to soil is expected to attenuate volatilization(SRC). 1-Octadecanol is not expected to volatilize from dry soil surfaces(SRC) based upon it's vapor pressure(4). Biodegradation of 1-octadecanol may be an important fate process in soil based on a mixed shake flask culture study(5). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 1.8X10+5(SRC), determined from a water solubility of 1.1X10-3 mg/L(2) and a regression-derived equation(3), indicates that 1-octadecanol is expected to adsorb to suspended solids and sediments(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 8.4X10-4 atm-cu m/mole(SRC), calculated from its water solubility(2) and vapor pressure, 2.7X10-6 mm Hg(4), values. Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 2.8 hours and 7 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 140 days if adsorption is considered (5). According to a classification scheme(6), an estimated BCF value of 2.8X10+4(3), from its water solubility(2), suggests the potential for bioconcentration in aquatic organisms is very high(SRC). A percent theoretical oxygen demand value of 0.3 in 24 hrs using a Warburg test(7) suggests that biodegradat 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-octadecanol, which has a vapor pressure of 2.7X10-6 mm Hg at 25 °C(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase 1-octadecanol 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 about 14 hours(3), calculated from its rate constant of 2.67X10-11 cu cm/molecule-sec at 25 °C(SRC), that was derived using a structure estimation method(3). Particulate-phase 1-octadecanol may be removed from the air by wet or dry deposition(SRC). Source: Hazardous Substances Data Bank (HSDB)
