The Henry's Law constant for 1,2,4-trimethylbenzene was measured as 6.16X10-3 atm-cu m/mol(1). This value indicates that 1,2,4-trimethylbenzene will volatilize from moist soil and water surfaces(2). Based on this Henry's Law constant, the estimated volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(2) is approximately 3 hours(SRC). The estimated volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(2) is approximately 4 days(SRC). Volatilization of 1,2,4-trimethylbenzene from dry soil surfaces is expected(SRC) based upon its vapor pressure of 2.1 mm Hg(3).

Literature: #Complete removal of 1,2,4-trimethylbenzene (at 0.068 ug/mL soil extract) from sandy loam soil samples contaminated with jet fuel was reported within 5 days; sterile samples with 1,2,4-trimethylbenzene at 0.057 ug/mL soil extract also showed complete removal of this compound within 5 days, probably through evaporation(1). Jet fuel added to water (and then stirred) had an average volatilization ratio (volatilization rate constant of the compound/oxygen reaeration rate constant) of 0.59 for JP-4 fuel and a ratio of 0.45 for JP-8 fuel for the 1,2,4-trimethylbenzene component, indicating high volatility of this compound from water(2).

A Koc value of 537 was measured for 1,2,4-trimethylbenzene in a German soil (80.5% sand 12.3% silt, 7.2% clay, 2.48% organic carbon). According to a suggested classification scheme(2), this Koc value suggests that 1,2,4-trimethylbenzene will have low mobility in soil(SRC).

The Henry's Law constant for benzyl alcohol is 3.37X10-7 atm cu m/mole(1). This Henry's Law constant indicates that benzyl alcohol is expected to be essentially nonvolatile from water and moist soil surfaces(2). 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)(2) is estimated as 113 days(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(2) is estimated as 825 days(SRC). Benzyl alcohol's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Benzyl alcohol is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 9.4X10-2 mm Hg(3).

Experimental Koc values for benzyl alcohol were <5 for three different soils; Apison (0.11% organic carbon), Fullerton (0.06% organic carbon), and Dormont (1.2% organic carbon)(1). An experimental Koc of 15 was determined for benzyl alcohol on a red-brown Australian soil (1.09% organic carbon)(2,3). A log Koc of 1.43 has also been reported(4). According to a classification scheme(5), these Koc values suggest that benzyl alcohol is expected to have very high mobility in soil.

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-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).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of n-heptane can be estimated to be 240(SRC). According to a classification scheme(2), this estimated Koc value suggests that n-heptane is expected to have moderate mobility in soil.

The Henry's Law constant for 3-methylpentane is estimated as 1.7 atm-cu m/mole(SRC) derived from its vapor pressure, 190 mm Hg(1), and water solubility, 17.9 mg/L(2). This Henry's Law constant indicates that 3-methylpentane 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 57 minutes(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 3.7 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 11 days if adsorption is considered(4). 3-Methylpentane's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of 3-methylpentane from dry soil surfaces may exist(SRC) based upon its vapor pressure(1).

The Koc of 3-methylpentane is estimated as 2,200(SRC), using a log Kow of 3.60(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 3-methylpentane is expected to have slight mobility in soil.
