Volatilization | The Henry's Law constant for alpha,beta-thujone is estimated as 1.6X10-5 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that alpha,beta-thujone 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 3 days(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 26 days(SRC). alpha,beta-Thujone's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). alpha,beta-Thujone is expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 0.45 mm Hg(SRC), determined from a fragment constant method(3).

Soil Adsorption | Using a structure estimation method based on molecular connectivity indices(1), the Koc of alpha,beta-thujone can be estimated to be 390(SRC). According to a classification scheme(2), this estimated Koc value suggests that alpha,beta-thujone is expected to have very moderate mobility in soil.
