UGW

The Henry's Law constant for 2,4-di-tert-butylphenol is estimated as 3.7X10-5 atm-cu m/mole(SRC) derived from its vapor pressure, 4.77X10-3(1) and water solubilty, 35 mg/L(2). This Henry's Law constant indicates that 2,4-di-tert-butylphenol 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)(3) is estimated as 1.6 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)(3) is estimated as 16 days(SRC). 2,4-Di-tert-butylphenol's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(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 120 months if adsorption is considered(4). 2,4-Di-tert-butylphenol is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure(1).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of 2,4-di-tert-butylphenol can be estimated to be 9000(SRC). According to a classification scheme(2), this estimated Koc value suggests that 2,4-di-tert-butylphenol is expected to be immobile in soil(SRC).

The Henry's Law constant for phenol is 3.33X10-7 atm-cu m/mol at 25 deg C(1). This Henry's Law constant indicates that phenol is expected to be essentially nonvolatile from water surfaces(2). Phenols's Henry's Law constant indicates that volatilization from moist soil surfaces in not expected to occur(SRC). Phenol is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 0.35 mm Hg(3).
Literature: (1) Gaffney JS et al; Environ Sci Technol 21: 519-23 (1987))(2) Lyman WJ et al; Handbook of Chemical Property Estimation Methods. Washington, DC: Amer Chem Soc pp. 15-1 to 15-29 (1990) (3) Bingham E et al, eds; Patty's Toxicology. 5th ed. NY, NY: John Wiley & Sons Inc. 4: 383 (2001)

Phenol is reported to have low adsorptivity to clay soils and silt loam(1) and no adsorption to aquifer material(3) and montmorillonite and kaolinite clays(8). The Koc for phenol to a Batcombe silt loam soil (pH 6.7, organic carbon 2.51%) was 30(6). It was 16 for a Brookstone clay loam (pH 5.7, organic matter 5.1%) and varied with pH and iron content of the soil(7). The Freundlich K and (1/N) for phenol in Captina (pH 5.7, 1.1 % organic matter) and Palouse silt loam (pH 5.7, 3.6% organic matter) soils were 0.58 (1.15) and 0.81 (1.00)(2); the Koc values for these soils are 91 and 39(SRC). Based on the reported Koc values, phenol would be expected to generally exhibit very high mobility in soil, based on a classification scheme(4). In a study of the adsorption of phenol onto siltstone associated with a Wyoming coal deposit suitable for in situ gasification, the pH of the solution was the major controlling factor with adsorption occurring at pH's below the pKa of phenol and no adsorption occurring at pH's above the pKa(5). The log of the Freundlich K value was approximately -4(5). Therefore, phenol may be transported by groundwater near in situ coal gasification sites due to the elevated pH's at these sites after gasification(5). The pKa of phenol is 9.99(9), indicating that it will be partially dissociated at the upper end of environmental pH range and its mobility may be pH dependent(SRC). In general, anions generally do not adsorb to organic carbon and clay as strongly as their neutral counterparts(10).

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 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).

The Henry's Law constant for 2-xylene has been measured as 5.18X10-3 atm-cu m/mole(1). This Henry's Law constant indicates that 2-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 3.2 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 4.1 days(SRC). 2-Xylene's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). 2-Xylene is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 6.65 mm Hg at 25 deg C(3).

Koc values measured for 2-xylene in various soils (% organic matter) were 24 in Wendover silty clay (16.2%), 26 in Vaudreil sand loam (10.0%), 68 in St. Thomas sand (3.1%), and 138 in Grimsby silt loam (1.0%)(1). Batch adsorption tests, using three solid sandy aquifer materials gave a Koc of 129(2). The Koc for 2-xylene in surface sediments collected from the central Tamar estuary in the UK was 25.4(3). The Koc values for 2-xylene in two river sediments (% organic matter 6.5-16.9 wt%) was 209 and 251, respectively(4). According to a classification scheme(5), these measured Koc values suggests that 2-xylene is expected to have very high to moderate mobility in soil. Using OECD Guideline 121 (estimating Koc via HPLC), the Koc of 2-xylene was estimated to be 537(6). Concentration enhancement has been observed for 2-xylene in a dune-infiltration project on the Rhine River(7); however, no 2-xylene reached groundwater under a rapid infiltration site(8). The log Koc for 2-xylene in coal sediment (% organic matter 52 wt%) was 2.40(4).
