The Henry's Law constant for terpinolene is 2.62X10-2 atm-cu m/mole(1). This Henry's Law constant indicates that terpinolene 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). However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column. The estimated volatilization half-life from a model pond is 48 days if adsorption is considered(3). Terpinolene is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure of 7.43X10-1 mm Hg(4).

The Koc of terpinolene is estimated as 7,600(SRC), using a log Kow of 4.47(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that terpinolene is expected to be immobile in soil.
