The Henry's Law constant for 1,2,3-trimethylbenzene is 4.36X10-3 atm-cu m/mole(1). This Henry's Law constant indicates that 1,2,3-trimethylbenzene 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 3.4 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). 1,2,3-Trimethylbenzene's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). 1,2,3-Trimethylbenzene is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 1.69 mm Hg(3).

1,2,3-Trimethylbenzene has measured log Koc values of 3.04(1) and 2.80(2-5). These values correspond to Koc values of 1,096 and 630. 1,2,3-Trimethylbenzene also has a reported log Kom value of 2.80(6-7). According to a classification scheme(8), these Koc values suggest that 1,2,3-trimethylbenzene is expected to have low mobility in soil(SRC).
