Based on water and vapor phase mass transfer coefficients, the volatilization half-life of iso-octane at 25 deg C from a still body of water at a depth of 1 m was estimated to be 5.6 hrs(1). Using more realistic winding blowing conditions, the evaporation half-life of the compound from a model river 1 meter deep, flowing at 1 m/sec with a wind speed of 3 m/sec was estimated to be 3.1 hrs(2). However, neither estimation method considers the effect of adsorption on the rate of volatility. Using EXAMS model which considers various input parameters including the effect of adsorption, the volatilization half-life of iso-octane from a model pond has been estimated to be 15 days(3,SRC).

The adsorption of several hydrocarbons including iso-octane in five types of soil was studied by measuring the retention volumes(1). Hydrocarbon retention by dry soils increased with molecular weight and unsaturation and decreased with branching. The retention volume of iso-octane was found to be high, but the authors did not provide any Koc values. The log Koc for iso-octane in soil has been estimated to be 3.43 from the water solubility of the compound(4) and a regression equation(2). The average log Koc for this compound in sediments from a salt marsh, a pond and a river was 4.35. Therefore, iso-octane is expected to generally remain strongly adsorbed to soil and sediments(5,SRC).
