Toluene

CAS RN:108-88-3

Soil Adsorption / Mobility

The Koc of toluene was reported as 178 in a sandy soil(1) and as 37 (Wendover silty loam), 160 (Grimsby silt loam), 160 (Vaudreil sandy loam) and 46 (sandy soil)(2). The Koc of toluene in lake sediment was measured as 166(3). According to a classification scheme(4), these measured Koc values suggest that toluene is expected to have high to moderate mobility in soil.
In association with clay minerals, toluene's adsorption is inversely proportional to the pH of the soil. Approximately 40-70% of toluene applied to the surface of sandy soils is volatilized.
