The Henry's Law constant for toluene is 6.64X10-3 atm-cu m/mole(1). This Henry's Law constant indicates that toluene is expected to volatilize from water 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 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)(2) is estimated as 3.8 days(SRC). Toluene's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Toluene is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 28.4 mm Hg(3). The air-water interface equilibrium partitioning coefficient for toluene, at a concentration of 0.47 mg/L, has been reported to be 0.223, 0.226, 0.273, and 0.336 at 26.9, 31.9, 36.9, and 41.9 deg C, respectively(4). A first-order volatilization rate calculated for toluene from water using an inverse reactive simulation was reported as 6.62X10-6/sec(5). The volatilization half-life of toluene from a water column of one meter depth was estimated to be 5.18 hours(6). Toluene was reported to have a disappearance half-life of <2 days due to volatilization in two different soil types, a Captina silt loam and a McLaurin sandy loam(7).

The Koc of toluene was reported as 178 in a sandy soil(1) and as 37 (Wendover silty loam), 160 (Grimsby silt loam), 160 (Vaudreil sandy loam) and 46 (sandy soil)(2). The Koc of toluene in lake sediment was measured as 166(3). According to a classification scheme(4), these measured Koc values suggest that toluene is expected to have high to moderate mobility in soil.

The Henry's Law constant for p-cymene is estimated as 0.011 atm-cu m/mole(SRC), derived from its vapor pressure, 1.5 mm Hg(1), and water solubility, 23.4 mg/L(2). This Henry's Law constant indicates that p-cymene 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 if adsorption is neglected(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 4.6 days if adsorption is neglected(SRC). The volatilization half-life from a model pond is about 30 days if adsorption is considered(4). p-Cymene's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). p-Cymene is 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 p-cymene can be estimated to be 1120(SRC). According to a classification scheme(2), this estimated Koc value suggests that p-cymene is expected to have low mobility in soil.

The Henry's Law constant for m-cymene is estimated as 7.15X10-3 atm-cu m/mole(SRC) derived from its vapor pressure, 1.72 mm Hg(1), and water solubility, 42.5 mg/L(2). This Henry's Law constant indicates that m-cymene 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 4.6 days(SRC). m-Cymene's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of m-cymene from dry soil surfaces may exist based upon its vapor pressure(1).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of m-cymene can be estimated to be 1120(SRC). According to a classification scheme(2), this estimated Koc value suggests that m-cymene is expected to have low mobility in soil.

The Henry's Law constant for 1,2,3-trimethylbenzene is 4.36X10-3 atm-cu m/mole(1). This Henry's Law constant indicates that 1,2,3-trimethylbenzene is expected to volatilize from water 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 3.4 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)(2) is estimated as 4.4 days(SRC). 1,2,3-Trimethylbenzene's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). 1,2,3-Trimethylbenzene is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 1.69 mm Hg(3).

The Henry's Law constant for 1,3,5-trimethylbenzene was measured as 8.77X10-3 atm-cu m/mole(1). This Henry's Law constant indicates that 1,3,5-trimethylbenzene is expected to volatilize rapidly from water 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 1.2 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)(2) is estimated as 4.4 days(SRC). 1,3,5-Trimethylbenzene's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). 1,3,5-Trimethylbenzene is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 2.48 mm Hg(3). Residence times (with respect to volatilization) for 1,3,5-trimethylbenzene were calculated as 220 hours for both winter and summer conditions in Narragansett Bay(4). Complete removal of 1,3,5-trimethylbenzene (at 0.035 ug/ml soil extract) from sandy loam soil samples contaminated with jet fuel was reported within 5 days; sterile samples with 1,3,5-trimethylbenzene at 0.035 ug/ml soil extract also showed complete removal of this compound within 5 days, probably by evaporation(5).

The Koc of 1,3,5-trimethylbenzene has been measured at a range of 501-1,445(1-4). According to a classification scheme(5), this Koc range suggests that 1,3,5-trimethylbenzene is expected to have low mobility in soil. 1,3,5-Trimethylbenzene was detected in soil leachate samples following the addition of crude oil to the surface of a soil trough filled with sand(6).

The Henry's Law constant for 3-xylene is measured as 7.18X10-3 atm-cu m/mole(1). This Henry's Law constant indicates that 3-xylene is expected to volatilize rapidly from water 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 3.1 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)(2) is estimated as 4.1 days(SRC). 3-Xylene's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). 3-Xylene is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 8.29 mm Hg at 25 deg C(3).

A Koc value of 166 was measured for 3-xylene using sandy aquifer materials with an foc ranging from 0.0002 to 0.0225(1). Measured Koc values in soil have been reported to be 182(2), 166 and 275(3). According to a classification scheme(3), these Koc values suggest that 3-xylene is expected to have moderate mobility in soil. A Kp value (equilibrium-sorption coefficient) of 0.049 was measured for 3-xylene using a Borden soil column (98% sand, 0.29% organic carbon)(5). Benzene/toluene/xylene mixtures containing 3-xylene, were added to soil columns using aquifer material from the Cohansey aquifer (90% sand; 4.4% organic matter; pH-3.8); a partition coefficient of 8.74 was measured for 3-xylene(6). Adsorption coefficient values of 0.25, 0.23, and 0.02 were measured for 3-xylene, present in a benzene/toluene/ethylbenzene/xylene mixture, on montmorillonite, illite, and kaolinite (all with low to no organic carbon present), respectively, using a batch equilibrium technique(7). More 3-xylene vapor was sorbed by air-dry than oven-dry soil (Evesham clay; air-dry soil contained 37 g organic C, 350 g clay, and 60 g water/kg oven-dry soil) at relative vapor pressures of 3-xylene exceeding 0.6; this suggests that the planar 3-xylene molecule is either readily adsorbed by interlayer sites in the air-dry soil (more sites potentially available than in oven-dry soil) or, as it is a fairly soluble molecule, that some will dissolve in the water film in air-dry soil(8). 3-Xylene has been observed to pass through soil unchanged in concentration at a dune-infiltration site on the Rhine River(9). A soil leaching column study estimated a 3-xylene Koc of 282 using a chromatographic methodology(10).
