The Henry's Law constant for 2-ethylphenol is estimated as 4.6X10-6 atm-cu m/mole(SRC) from its experimental values for vapor pressure, 0.153 mm Hg at 25 deg C(1), and water solubility, 5340 mg/L at 25 deg C(2). This value indicates that 2-ethylphenol will volatilize from water surfaces(3,SRC). 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) is estimated as approximately 9 days(3,SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec) is estimated as approximately 68 days(3,SRC). 2-Ethylphenol's values for vapor pressure(1) and estimated Henry's Law constant(1,2,SRC) indicate that volatilization from dry and moist soil surfaces is possible, but is not likely to be a major fate process for this compound(SRC).

The Koc of 2-ethylphenol is estimated as approximately 530(SRC), using a measured log Kow of 2.47(1) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that 2-ethylphenol has moderate to low mobility in soil(SRC).

The Henry's Law constant for 2,6-di-t-butyl-p-cresol is estimated as 2.5X10-3 atm-cu m/mole(SRC) using a fragment constant estimation method(1). 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 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)(2) 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 volatilization half-life from a model pond is about 120 days when adsorption is considered(3). 2,6-Di-t-butyl-p-cresol's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). 2,6-Di-t-butyl-p-cresol is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 5.16X10-3 mm Hg(4).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of 2,6-di-t-butyl-p-cresol can be estimated to be 1.5X10+4(SRC). According to a classification scheme(2), this estimated Koc value suggests that 2,6-di-t-butyl-p-cresol is expected to be immobile in soil.

The Henry's Law constant for 4-xylene is measured as 6.90X10-3 atm-cu m/mole(1). This Henry's Law constant indicates that 4-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). 4-Xylene's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). 4-Xylene is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 8.84 mm Hg(3).

Koc values of 246 and 540 have been measured for 4-xylene in silt and sandy loam soils respectively(1). A Koc value of 204 was measured for 4-xylene using sandy aquifer materials(2). A median experimental Koc value of 295 has also been reported(3). According to a classification scheme(4), these Koc values suggest that 4-xylene is expected to have moderate to low mobility in soil. A soil leaching column study estimated a 4-xylene Koc of 331 using a chromatographic methodology(5). Another soil column leaching study estimated a Koc range of 118-298 based on HPLC measurement(6).

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).

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.

Based on an estimated Henry's Law constant of 8.48 atm-cu m/mole at 25 deg C(1,SRC), 1-tetradecene is expected to rapidly volatilize from water and moist soil to the atmosphere. The estimated half-life for volatilization from a model river 1 m deep flowing at 1 m/sec with a wind speed of 3 m/sec is 4.1 hrs(2,SRC). Its expected strong adsorption to soil and sediment may attenuate the rate of this process(SRC). The estimated half-life for volatilization from a model pond, which takes into account adsorptive processes, is 7.3 months(3,SRC). The vapor pressure of 1-tetradecene, 1.5X10-2 mm Hg at 25 deg C(4) indicates that volatilization from dry soil will not be an important fate process(SRC).
Literature: (1) Meylan WM, Howard PH; Environ Toxicol Chem 10: 1283-93 (1991) (2) Lyman WJ et al; Handbook of Chemical Property Estimation Methods NY: McGraw-Hill Chapt 15 (1982) (3) USEPA; EXAMS II (1987) (4) Daubert TE, Danner RP; Physical & Thermodynamic Properties of Pure Chemicals NY, NY: Hemisphere Pub Corp (1989)

Estimated soil adsorption coefficients ranging from 19,700 to 32,300 can be calculated for 1-tetradecene using appropriate regression equations(1) and its estimated water solubility, 4.0X10-4 mg/L at 25 deg C(1,SRC) obtained from a vapor pressure of 1.5X10-2 mm Hg at 25 deg C(2) and estimated Henry's Law constant of 8.48 atm-cu m/mole at 25 deg C(3,SRC), and its estimated octanol/water partition coefficient, 7.3(1,SRC), obtained from its estimated water solubility. These soil adsorption coefficients indicate that 1-tetradecene will be essentially immobile in soil(4).
