The Henry's Law constant for eugenol is estimated as 1.92X10-6 atm-cum/mole(SRC) derived from its extrapolated vapor pressure, 0.0221 mm Hg at 25deg C(1), and water solubility, 2460 mg/L at 25 deg C(2). This Henry's Law constant indicates that eugenol is expected to volatilize slowly 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 25 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 183 days(SRC). Eugenol's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). A theoretical model of soil volatilization predicts that 4-33% of eugenol applied to a soil surface will volatilize during the first 10 days(4); the fastest volatilization rates occur with lowest soil organic content and moisture content(4). Although eugenol's vapor pressure might suggest that volatilization from dry soil will not occur, the compound is used in fragrance and odorant applications that result in inhalation exposure(SRC); therefore, volatilization from dry soil is expected to occur(SRC).

The Koc of eugenol is estimated as 340(SRC), using a log Kow of 2.49(1) and a regression-derived equation(2). According to a classification scheme(3), these estimated Koc values suggest that eugenol is expected to have moderate to lowmobility 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 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-phenylethanol estimated from its vapor pressure, 0.0868 mm Hg at 25 deg C(1), and water solubility, 16,000 mg/L(2), is 1.5X10-7 atm-cu m/mol(SRC). Using this value for the Henry's Law constant, one can estimate a volatilization half-life of 2-phenylethanol in a model river 1 m deep flowing at 1 m/s with a wind speed of 3 m/s is 46.5 days(3,SRC). 2-Phenylethanol's relatively low Henry's Law constant and vapor pressure suggest that volatilization from moist and dry soil surfaces will be minimal(SRC).

Using an estimation method based on molecular connectivity indices(1), the Koc for 2-phenylethanol is estimated to be 29(SRC). According to a suggested classification scheme(2), this Koc value suggests that 2-phenylethanol will have very high mobility in soil(SRC).

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.
