The Henry's Law constant for benzaldehyde is 2.67X10-5 atm-cu m/mole(1). This Henry's Law constant indicates that benzaldehyde 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 1.5 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 14 days(SRC). Benzaldehyde's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Benzaldehyde is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 1.27 mm Hg at 25 deg C(3).
Literature: (1) Betterton EA, Hoffmann MR; Environ Sci Technol 22: 1415-8 (1988) (2) Lyman WJ et al; Handbook of Chemical Property Estimation Methods. Washington, DC: Amer Chem Soc pp. 15-1 to 15-29 (1990) (3) Ambrose D et al; J Chem Therm 7: 1143-57 (1975)

Using a structure estimation method based on molecular connectivity indices(1), the Koc of benzaldehyde can be estimated to be 11(SRC). According to a classification scheme(2), this estimated Koc value suggests that benzaldehyde 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 methyl mercaptan is estimated as 0.0031 atm-cu m/mole(SRC) derived from its vapor pressure, 1,510 mm Hg(1), and water solubility, 15,400 mg/L(2). This Henry's Law constant indicates that methyl mercaptan 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 0.8 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 2.8 days(SRC). Methyl mercaptan's Henry's Law constant indicates that volatilization from moist soil surfaces is expected to occur(SRC). Methyl mercaptan is expected to volatilize rapidly from dry soil surfaces based upon its vapor pressure and because it is a gas a temperatures above 6 deg C(SRC). However, gaseous methyl mercaptan gas has been found to strongly adsorb to moist and dry soil surfaces suggesting that adsorption might be an environmental sink for methyl mercaptan(4). Therefore, the importance of volatilization from soil surfaces may be attenuated by adsorption(SRC).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of methyl mercaptan can be estimated to be 13(SRC). According to a classification scheme(2), this estimated Koc value suggests that methyl mercaptan is expected to have very high mobility in soil. Gaseous methyl mercaptan has been observed to partition to soils(3). For example, when gaseous methyl mercaptan was passed over six air-dried and moist (50% field capacity) soils, 2.4-32.1 mg/g and 2.2-21.4 mg/g of methyl mercaptan rapidly adsorbed to the dry and moist soils, respectively(3). Neither the capacity or rate of sorption was correlated to soil pH, organic matter content, or clay content; sterile controls ruled out the involvement of microorganisms(3); it was suggested that adsorption to soil surfaces might be an environmental sink for gaseous methyl mercaptan(3).
