The Henry's Law constant for heneicosane is estimated as 120 atm-cu m/mole(SRC), based upon its vapor pressure, 8.73X10-8 mm Hg(1), and water solubility, 2.9X10-8 mg/L(2). This Henry's Law constant indicates that heneicosane may 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 1.8 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 6.8 days(SRC). However, adsorption to soil is expected to attenuate volatilization(SRC). The estimated volatilization half-life from a model pond is greater than 2 years if adsorption is considered(4). Heneicosane is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure.

The Henry's Law constant for nonadecane is estimated as 68 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that nonadecane 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)(3) is estimated as 1.6 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)(3) is estimated as 6.5 days(SRC). However, adsorption to suspended solids and sediment is expected to attenuate volatilization(SRC). The estimated volatilization half-life from a model pond is greater than 2 years if adsorption is considered(4).

The Henry's Law constant for n-undecane is estimated as 6.1 atm-cu m/mole(SRC) derived from its vapor pressure, 0.412 mm Hg(1), and water solubility, 0.014 mg/L(2). This Henry's Law constant indicates that n-undecane 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 3.6 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)(3) is estimated as 5 days(SRC). However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column. The estimated volatilization half-life from a model pond is about 1 month if adsorption is considered(4). n-Undecane's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). n-Undecane is not expected to volatilize from dry soil surfaces based upon its vapor pressure(SRC).

The Henry's Law constant for hexadecane is estimated as 21 atm-cu m/mole(SRC) derived from its vapor pressure, 0.00149 mm Hg(1), and water solubility, 2.1X10-5 mg/L(2). This Henry's Law constant indicates that hexadecane 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 4 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 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 estimated volatilization half-life from a model pond is approximately 24 months if adsorption is considered(4). n-Hexadecane's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Hexadecane is not expected to volatilize from dry soil surfaces based upon its vapor pressure(SRC).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of hexadecane can be estimated to be 53,000(SRC). According to a classification scheme(2), this estimated Koc value suggests that hexadecane is expected to be immobile in soil(SRC). From the experimental value of Freundlich adsorption constants and organic carbon contents in three Canadian soils (Wendover 16.2% OC; Vaudreil 10.0% OC; Grimsby 1.0% OC)(3), Koc values can be estimated to be in the range of approximately 50-400(SRC). The experimental data of other investigators suggest that less than 20% of hexadecane from solution is adsorbed in soil, sludge and sediment(4-6). However, in all the adsorption experiments(3-6), the concentration of hexadecane solution used for the adsorption study far exceeded the aqueous solubility of hexadecane making the results questionable(SRC).

The Henry's Law constant for n-tetradecane is estimated as 11.9 atm-cu m/mole(SRC) derived from its vapor pressure, 0.015 mm Hg(1), and water solubility, 0.00033 mg/L(2). This Henry's Law constant indicates that n-tetradecane 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 4 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 5.6 days(SRC). However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column. The estimated volatilization half-life from a model pond is 28 months if adsorption is considered(4). n-Tetradecane's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). n-Tetradecane is not expected to volatilize from dry soil surfaces based upon its vapor pressure(SRC).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of n-tetradecane can be estimated to be 16,000(SRC). According to a classification scheme(2), this estimated Koc value suggests that n-tetradecane is expected to be immobile in soil. Laboratory soil column elution experiments showed that the percent of n-tetradecane adsorbed to three different native soil types ranged from 2.2-5.98%(3).

The Henry's Law constant for octadecane is estimated as 1.9X10-2 atm-cu m/mole(1) from its vapor pressure, 3.41X10-4 mm Hg(2), and water solubility, 6.0X10-3 mg/L(3). This Henry's Law constant indicates that octadecane is expected to volatilize rapidly from water surfaces(4). 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)(1) is estimated as 1.7 hours 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)(1) is estimated as 6.3 days(SRC). However, adsorption to suspended solids and sediment is expected to attenuate volatilization(SRC). The estimated volatilization half-life from a model pond is greater than 2 years if adsorption is considered(5). Octadecane has a vapor pressure of 3.41X10-4 mm Hg and exists as a liquid under environmental conditions; therefore, octadecane may volatilize from dry soil.
