| Volatilization | 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). Nonadecane is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 4.9X10-5 mm Hg(5).

| Soil Adsorption | The Koc of nonadecane is estimated as 3.2X10+5(SRC), using an estimated log Kow of 9.67(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that nonadecane is expected to be immobile in soil.
