| Volatilization | The Henry's Law constant for phenyl ethyl ketone is estimated as 1.3X10-4 atm-cu m/mole at 20 deg C(SRC) from its experimental values for vapor pressure, 0.15 mm Hg at 20 deg C(1), and water solubility, 2000 mg/l at 20 deg C(1). This value indicates that phenyl ethyl ketone will volatilize from water surfaces(3,SRC). 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) is estimated as approximately 11 hours(3,SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec) is estimated as approximately 7 days(2,SRC). Phenyl ethyl ketone's vapor pressure(1) and Henry's Law constant(1,2,SRC) indicate that volatilization from dry and moist soil may occur(SRC).

| Soil Adsorption | The Koc of phenyl ethyl ketone is estimated as approximately 370(SRC), using an experimental log Kow of 2.19(1) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that phenyl ethyl ketone has medium mobility in soil(SRC).
