| Volatilization | The Henry's Law constant for 1-decene is estimated as 2.68 atm-cu m/mole(SRC) from its vapor pressure, 1.67 mm Hg(1), and water solubility, 0.115 mg/l(2). This Henry's Law constant indicates that 1-decene 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 1.2 hrs(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, the volatilization half-life does not take into account the effects of adsorption. This is apparent from the results of two EXAMS model runs, one in which the effect of adsorption was considered, yielding an estimated half-life of 11 days in a model pond 2 m deep, and one in which the effect of adsorption was ignored, yielding an estimated half-life of 56 hours in a model pond 2 m deep(4). 1-Decene's Henry's Law constant(1,2) indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of 1-decene from dry soil surfaces may exist(SRC) based upon a vapor pressure of 1.67 mm Hg(1).

| Soil Adsorption | Using a structure estimation method based on molecular connectivity indices(1), the Koc for 1-decene can be estimated to be about 1720(SRC). According to a classification scheme(2), this estimated Koc value suggests that 1-decene is expected to have low mobility in soil.
