The Henry's Law constant for n-octane is estimated as 3.2 atm-cu m/mole(SRC) derived from its vapor pressure, 14.1 mm Hg(1), and water solubility, 0.66 mg/L(2). This Henry's Law constant indicates that n-octane is expected to volatilize rapidly from water surfaces(3). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(3) is estimated as 3 hours(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(3) is estimated as 4.2 days(SRC). Volatilization from water surfaces may be attenuated by adsorption to suspended solids and sediment in the water column(SRC). The estimated volatilization half-life from a model pond is 11 months if adsorption is considered(4). However, in a study using a jet fuel mixture and sterile freshwater controls from the Escambia River (Florida), a 99% loss of n-octane was attributed to evaporation at 25 deg C(5). n-Octane's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). The disappearance of n-octane was rapid in soil/water mixture (concentration of soil, 25 g/150 mL)(6); an initial concentration of 0.177 ug/mL n-octane disappeared completely in 5 days using a sterile sandy loam soil with an organic matter content of 5.1%(6). The potential for volatilization of n-octane from dry soil surfaces may exist(SRC) based upon its vapor pressure(1).

The Koc of n-octane is estimated as 3.1X10+4(SRC), using a log Kow of 5.18(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that n-octane is expected to be immobile in soil. Freundlich absorption coefficients of log 4.04 and log 3.49 were measured in Oberlausitz lignite (11.1% moisture content; 53.5 wt% carbon content; 0.6 wt % nitrogen content) and Pahokee peat soil (10.2% moisture content; 46.1 wt% carbon content; 3.3 wt % nitrogen content), respectively(4). Gaseous transport of volatile n-octane in unsaturated porous media was shown to be influenced by air-water interfacial adsorption and water-partitioning(5). Sorption of n-octane from air to snow was measured, resulting in a sorption coefficient of log -4.41 cu m/sq m at -6.8 deg C(6).

The Henry's Law constant for n-decane is estimated as 5.15 atm-cu m/mole(SRC) derived from its vapor pressure, 1.43 mm Hg(1), and water solubility, 0.052 mg/L(2). This Henry's Law constant indicates that n-decane is expected to volatilize rapidly from water surfaces(3). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(3) is estimated as 3.5 hours(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(3) is estimated as 4.7 days(SRC). n-Decane's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). n-Decane is expected to volatilize from dry soil surfaces based upon its vapor pressure(SRC). Biodegradation studies in soil have observed volatilization to be a more important removal process than biodegradation for n-decane(4,5).

The Henry's Law constant for heptadecane is estimated as 3.1X10-2 atm-cu m/mole(SRC) derived from its vapor pressure, 2.28X10-4 mm Hg(1), and water solubility, 2.3X10-3 mg/L(2). This Henry's Law constant indicates that heptadecane is expected to volatilize from water surfaces(3). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(4) is estimated as 1.6 hours(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(4) is estimated as 6.2 days(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 greater than 2 years if adsorption is considered(5). Heptadecane's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Heptadecane is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(1).

The Henry's Law constant for hexadecane is estimated as 21 atm-cu m/mole(SRC) derived from its vapor pressure, 0.00149 mm Hg(1), and water solubility, 2.1X10-5 mg/L(2). This Henry's Law constant indicates that hexadecane is expected to volatilize rapidly from water surfaces(3). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(3) is estimated as 4 hours(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(3) is estimated as 6 days(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 approximately 24 months if adsorption is considered(4). n-Hexadecane's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Hexadecane is not expected to volatilize from dry soil surfaces based upon its vapor pressure(SRC).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of hexadecane can be estimated to be 53,000(SRC). According to a classification scheme(2), this estimated Koc value suggests that hexadecane is expected to be immobile in soil(SRC). From the experimental value of Freundlich adsorption constants and organic carbon contents in three Canadian soils (Wendover 16.2% OC; Vaudreil 10.0% OC; Grimsby 1.0% OC)(3), Koc values can be estimated to be in the range of approximately 50-400(SRC). The experimental data of other investigators suggest that less than 20% of hexadecane from solution is adsorbed in soil, sludge and sediment(4-6). However, in all the adsorption experiments(3-6), the concentration of hexadecane solution used for the adsorption study far exceeded the aqueous solubility of hexadecane making the results questionable(SRC).

The Henry's Law constant for n-heptane is estimated as 1.8 atm-cu m/mole(SRC) derived from its vapor pressure, 46 mm Hg(1), and water solubility, 3.4 mg/L(2). This Henry's Law constant indicates that n-heptane is expected to volatilize rapidly from water surfaces(3). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(3) is estimated as 2.9 hours(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(3) is estimated as 4.0 days(SRC). n-Heptane's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of n-heptane from dry soil surfaces may exist(SRC) based upon a vapor pressure of 46 mm Hg(1).

Literature: #In a study quantifying the passive volatilization of a synthetic gasoline and its individual components in three air-dried soils over a period of up to 16 days, n-heptane had a volatilization half-life of approximately 10 hours in a loamy sand at a depth of 50 mm(1). Using different soil types, n-heptane, at a depth of 50 mm, volatilized first from sand, followed by a loamy sand and finally a silt loam, showing that as the particle size of the soil decreased and the clay and organic content matter increased, the volatilization rate decreased(1). Complete volatilization of n-heptane from a tray containing a gasoline pool thickness of 7 mm at a temperature of 18.5 deg C occurred after approximately 5.6 hours(1). In a study in which a jet fuel mixture was incubated in freshwater from the Escambia River, FL at 25 deg C, a 99% loss of n-heptane in the controls was attributed to evaporation(2). n-Heptane as a component of missile fuel was also lost to volatilization within 5 hours when incubated with water from the Range Point salt marsh, FL(3). n-Heptane degradation was observed in active and sterile sandy loam treated with JP-4 jet fuel (10 uL per gram of soil)(4). The concentration of n-heptane at 0 time was 0.277 ug/mL in the active soil and 0.235 ug/mL in the sterile soil while the concentrations in both soils were 0 ug/mL when they were tested a second time after 5 days; evaporation was considered to be the primary removal process(4).

The Henry's Law constant for dodecane is estimated as 8.2 atm-cu m/mole(SRC) derived from its vapor pressure, 0.135 mm Hg(1), and water solubility, 3.7X10-3 mg/L(2). This Henry's Law constant indicates that dodecane is expected to volatilize rapidly from water surfaces(3). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(3) is estimated as 4 hours(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(3) is estimated as 5 days(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 32 days if adsorption is considered(4). Dodecane's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Dodecane is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(1).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of dodecane can be estimated to be 4800(SRC). According to a classification scheme(2), this estimated Koc value suggests that dodecane is expected to have slight mobility in soil. In a study conducted to mimic a spill of 1.27 L/sq m, dodecane (present in JP-4 jet fuel) was transported to a depth of 10 cm; at the end of the study (134 days), it was no longer detected(3). In another study, it was determined that dodecane is slowly intercalated into well dried montmorillonite clay(4).

The Henry's Law constant for n-nonane is estimated as 3.4 atm-cu m/mole(SRC) derived from its vapor pressure, 4.45 mm Hg(1), and water solubility, 22 mg/L)(2). This Henry's Law constant indicates that n-nonane is expected to volatilize rapidly from water surfaces(3). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(3) is estimated as 3.3 hours(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(3) is estimated as 4.5 days(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(4). n-Nonane's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of n-nonane from dry soil surfaces may exist(SRC) based upon the vapor pressure(1).

The Koc of n-nonane is estimated as 8.0X10+4(SRC), using a log Kow of 5.65(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that n-nonane is expected to be immobile in soil. Freundlich absorption coefficients of log 4.50 and log 4.01 were measured in Oberlausitz lignite (11.1% moisture content; 53.5 wt% carbon content; 0.6 wt % nitrogen content) and Pahokee peat soil (10.2% moisture content; 46.1 wt% carbon content; 3.3 wt % nitrogen content), respectively(4).
