The Henry's Law constant for beta-ionone is estimated as 8.1X10-5 atm-cu m/mole(SRC) derived from its vapor pressure, 0.054 mm Hg(1), and water solubility, 169 mg/L(1). This Henry's Law constant indicates that beta-ionone is expected to volatilize 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)(2) is estimated as 19 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 10 days(SRC). beta-Ionone's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Even though the vapor pressure is low environmentally at standard temperature and pressure, there is a detectable odor; therefore, beta-ionone may volatilize from dry soil(SRC).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of beta-ionone can be estimated to be 670(SRC). According to a classification scheme(2), this estimated Koc value suggests that beta-ionone is expected to have low mobility in soil.
