The Henry's Law constant for tetrahydrofuran is 7.05X10-5 atm-cu m/mole(1). This Henry's Law constant indicates that tetrahydrofuran 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 13 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 6.6 days(SRC). Tetrahydrofuran's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Tetrahydrofuran is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 162 mm Hg(3).

Koc values of 23 and 18 were determined for tetrahydrofuran using a zero headspace extractor vessel in Captina silt loam (pH = 4.97, organic carbon = 1.49%) and McLaurin sandy loam (pH = 4.43, organic carbon = 0.66%), respectively(1). According to a classification scheme(2), these measured Koc values suggest that tetrahydrofuran is expected to have very high mobility in soil(SRC). A retardation factor of 1.0 was measured for tetrahydrofuran in a ground water system in Indiana(3). A retardation factor of 2.2, based on plume length, was measured for tetrahydrofuran in an aquifer beneath a landfill in Ottawa, Ontario, Canada(4). A column packed with aquifer material was used to measure a retardation factor of 1.2 for tetrahydrofuran(5).

The Henry's Law constant for ethylene oxide is 1.48X10-4 atm-cu m/mole(1). This Henry's Law constant indicates that ethylene oxide 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 6 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 days(SRC). Ethylene oxide is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 1.31X10+3 mm Hg(3). Although no data on the volatilization of ethylene oxide from soil could be found, a study of the dissipation of ethylene oxide from fumigated commodities gave half-life values of 4 hr to 17.5 days(4).

Koc of ethylene oxide was reported to be 2.20(1). According to a classification scheme(2), this estimated Koc value suggests that ethylene oxide is expected to have very high mobility in soil(SRC).

The Henry's Law constant for safrole is estimated as 9.1X10-6 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that safrole 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 5.3 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 42 days(SRC). Safrole's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Safrole is not expected to volatilize from dry soil surfaces(SRC) based upon an extrapolated vapor pressure of 0.0706 mm Hg(3).

Using a structure estimation method based on molecular connectivity indices(1), the Koc for safrole can be estimated to be 300(SRC). According to a classification scheme(2), this estimated Koc value suggests that safrole is expected to have moderate mobility in soil.
