The Henry's Law constant for 1,3,5-trimethylbenzene was measured as 8.77X10-3 atm-cu m/mole(1). This Henry's Law constant indicates that 1,3,5-trimethylbenzene 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 1.2 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 4.4 days(SRC). 1,3,5-Trimethylbenzene's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). 1,3,5-Trimethylbenzene is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 2.48 mm Hg(3). Residence times (with respect to volatilization) for 1,3,5-trimethylbenzene were calculated as 220 hours for both winter and summer conditions in Narragansett Bay(4). Complete removal of 1,3,5-trimethylbenzene (at 0.035 ug/ml soil extract) from sandy loam soil samples contaminated with jet fuel was reported within 5 days; sterile samples with 1,3,5-trimethylbenzene at 0.035 ug/ml soil extract also showed complete removal of this compound within 5 days, probably by evaporation(5).

The Koc of 1,3,5-trimethylbenzene has been measured at a range of 501-1,445(1-4). According to a classification scheme(5), this Koc range suggests that 1,3,5-trimethylbenzene is expected to have low mobility in soil. 1,3,5-Trimethylbenzene was detected in soil leachate samples following the addition of crude oil to the surface of a soil trough filled with sand(6).
