The Henry's Law constant for 1-heptene is estimated as 0.421 atm-cu m/mole(SRC) from its vapor pressure of 59.3 mm Hg(1) and water solubility of 18.2 mg/l at 25 deg C(2). This Henry's Law constant indicates that 1-heptene 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)(2) is estimated as 3 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 94 hours(SRC). 1-Heptene's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of 1-heptene from dry soil surfaces may exist(SRC) based upon the vapor pressure of this compound(1).

The Koc of 1-heptene is estimated as 3,500(SRC), using a log Kow of 3.99(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 1-heptene is expected to have slight mobility in soil(SRC).
