The Henry's Law constant for phenyl ethyl ketone is estimated as 1.3X10-4 atm-cu m/mole at 20 deg C(SRC) from its experimental values for vapor pressure, 0.15 mm Hg at 20 deg C(1), and water solubility, 2000 mg/l at 20 deg C(1). This value indicates that phenyl ethyl ketone 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 11 hours(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 7 days(2,SRC). Phenyl ethyl ketone's vapor pressure(1) and Henry's Law constant(1,2,SRC) indicate that volatilization from dry and moist soil may occur(SRC).

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 Henry's Law constant for furfural is estimated as 3.8X10-6 atm-cu m/mole(SRC) derived from its vapor pressure, 2.21 mm Hg(1), and water solubility, 7.41X10+4 mg/L(2). This Henry's Law constant indicates that furfural 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)(3) is estimated as 9.6 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 73 days(SRC). Furfural's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of furfural from dry soil surfaces may exist(SRC) based upon its vapor pressure(1).

The Koc of furfural is estimated as 40(SRC), using a log Kow of 0.41(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that furfural is expected to have very high mobility in soil.

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 phenyl 2-propanone is estimated as 4.0X10-6 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that phenyl 2-propanone 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 7 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 80 days(SRC). Phenyl 2-propanone's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Phenyl 2-propanone has an estimated vapor pressure of 0.16 mm Hg(SRC), determined from a fragment constant method(3) and exists as a liquid under environmental conditions; therefore, phenyl 2-propanone may volatilize from dry soil.

The Koc of phenyl 2-propanone is estimated as 80(SRC), using a log Kow of 1.44(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that phenyl 2-propanone is expected to have high mobility in soil.

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).
