Volatilization | The Henry's Law constant for beta-pinene is estimated as 0.16 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that beta-pinene is expected to volatilize rapidly 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 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 5 days(SRC). beta-Pinene's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column. The volatilization half-life from a model pond is about 340 days when adsorption is considered(3). beta-Pinene is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 2.93 mm Hg(4).

Soil Adsorption | The Koc of beta-pinene is estimated as 4,400(SRC), using a log Kow of 4.16(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that beta-pinene is expected to have slight mobility in soil.
