The Henry's Law constant for alpha-methylstyrene is estimated as 2.6X10-3 atm-cu m/mole(SRC) derived from its vapor pressure, 1.9 mm Hg(1), and water solubility, 116 mg/l(2). This Henry's Law constant indicates that alpha-methylstyrene 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 4 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 4 days(SRC). alpha- Methylstyrene's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of alpha-methylstyrene from dry soil surfaces may exist(SRC) based upon a vapor pressure of 1.9 mm Hg(1).

The Koc of alpha-methylstyrene is estimated as 1,900(SRC), using a log Kow of 3.48(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that alpha-methylstyrene is expected to have low mobility in soil(SRC).
