The Henry's Law constant for trimethylamine is 1.0X10-4 atm-cu m/mole(1). This Henry's Law constant indicates that trimethylamine is expected to volatilize from water surfaces(2). However, trimethylamine is a base with pKa of 9.8(3) and will exist primarily as a cation under environmental conditions (pH 5-9)(SRC). Thus, volatilization of trimethylamine from moist soil and water surfaces will not be an important fate process because cations do not volatilize(SRC). The potential for volatilization of trimethylamine from dry soil surfaces may exist(SRC) based upon a vapor pressure of 1,610 mm Hg(4).

The Koc of trimethylamine is estimated as 29(SRC), using a log Kow of 0.16(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that trimethylamine is expected to have very high mobility in soil(SRC). However, trimethylamine has a pKa of 9.8(4) and should exist primarily as a cation under environmental conditions (pH 5-9)(SRC). As a result, trimethylamine may have greater adsorption and less mobility than its estimated Koc value indicates since cations generally adsorb more strongly to soils containing organic carbon and clay than neutral species(5). Sorption coefficients for trimethylamine adsorption on montmorillonite, kaolinite and Flax Pond sediment (7% clay, 2.8% OM; Long Island, NY) were 15, 2 and 7 ml/g, respectively(6). The trimethylamine cation adsorbed strongest to the negatively-charged montmorillonite via electrostatic interactions(6).
