- Environmental Bioconcentration: An estimated BCF of 100 was calculated in fish for n-nonane(SRC), using a log Kow of 5.65(1) and a regression-derived equation(1). According to a classification scheme(2), 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 8.0X10+4(SRC), determined from a log Kow of 5.65(2) and a regression-derived equation(3), indicates that n-nonane is expected to be immobile in soil(SRC). Volatilization of n-nonane from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 3.4 atm-cu m/mole(SRC), derived from its vapor pressure, 4.45 mm Hg(4), and water solubility, 22 mg/L)(5). n-Nonane is expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(4). Evaporation was considered to be the primary removal mechanism during a study where n-nonane was completely removed from both sterile and non-sterile soils after 5 days(6). Under conditions where volatilization is hindered, biodegradation of n-nonane is expected to be an important fate process based on 100% degradation after 5 and 25 days in screening tests using seawater sediment and activated sewage sludge inocula, respectively(7,8), suggesting 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 8.0X10+4(SRC), determined from a log Kow of 5.65(2) and a regression-derived equation(3), indicates that n-nonane is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(4) based upon an estimated Henry's Law constant of 3.4 atm-cu m/mole(SRC), derived from its vapor pressure, 4.45 mm Hg(5), and water solubility, 22 mg/L)(6). Using this Henry's Law constant and an estimation method(4), volatilization half-lives for a model river and model lake are 3.3 hours and 4.5 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 155 days if adsorption is considered(7). According to a classification scheme(8), an estimated BCF of 100(SRC), from its log Kow(2) and a regression-derived equation(3), suggests the potential for bioconcentration in aquatic organisms is moderate(SRC).

- Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), n-nonane, which has a vapor pressure of 4.45 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase n-nonane 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 1.7 days(SRC), calculated from its rate constant of 1.02X10-11 cu cm/molecule-sec at 25 °C(3). n-Nonane does not contain chromophores that absorb at wavelengths >290 nm(4) and, therefore, is not expected to be susceptible to direct photolysis by sunlight(SRC).
