The Henry's Law constant for tetracosane is estimated as 280 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that tetracosane 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 1.9 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)(3) is estimated as 7.3 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). Tetracosane is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 4.07X10-6 mm Hg(5).

The Koc of tetracosane is estimated as 6.5X10+6(SRC), using an estimated log Kow of 12.13(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that tetracosane is expected to be immobile in soil.
