The Henry's Law constant for pyrrole is 1.8X10-5 atm-cu m/mole(1). This Henry's Law constant indicates that pyrrole 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 approximately 42 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 approximately 368 hours(SRC). Pyrrole's Henry's Law constant(1) indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of pyrrole from dry soil surfaces may exist(SRC) based upon a vapor pressure of 8.35 mm Hg(3).

The Koc of pyrrole is estimated as approximately 61(SRC), using a log Kow of 0.75(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that pyrrole is expected to have high mobility in soil.

The Henry's Law constant for furan is estimated as 5.4X10-3 atm-cu m/mole(SRC) derived from its vapor pressure, 600 mm Hg(1), and water solubility, 10,000 mg/L(2). This Henry's Law constant indicates that furan 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 2.5 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 3.3 days(SRC). Furan's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of furan from dry soil surfaces may exist(SRC) based upon its vapor pressure(1).

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.

The Henry's Law constant for ethylbenzene is 7.88X10-3 atm-cu m/mole(1). This Henry's Law constant indicates that ethylbenzene 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). Ethylbenzene's Henry's Law constant(1) indicates that volatilization from moist soil surfaces may occur(SRC). Ethylbenzene is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 9.6 mm Hg(3).

Measured ethylbenzene Koc values of 224(1), 240(2) and 257(3) have been reported. According to a classification scheme(4), these Koc values suggest that ethylbenzene is expected to have moderate mobility in soil. Sorption and desorption experiments demonstrated that the sorption process of ethylbenzene on marine sediments is reversible and that the sorption is even lower than expected from the log Kow data and the organic carbon content of the sediment(5); it was concluded that the marine sediment compartment is not an important sink for ethylbenzene(5). A soil leaching column study estimated an ethylbenzene Koc of 240 using a chromatographic methodology(6).

TRANS-CINNAMALDEHYDE (CONSTITUENT OF CINNAMOMUM CASSIA BARK) [DSC]

The Henry's Law constant for cinnamaldehyde is estimated as 3.5X10-6 atm-cu m/mole(SRC) derived from its vapor pressure, 2.89X10-2 mm Hg(1), and water solubility, 1,420 mg/L(2). This Henry's Law constant indicates that cinnamaldehyde 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 290 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 91 days(SRC). Cinnamaldehyde's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Cinnamaldehyde is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(1).

The Koc of cinnamaldehyde is estimated as 37(SRC), using a log Kow of 1.9(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that cinnamaldehyde is expected to have very high mobility in soil.

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).
