| Volatilization | A pKa of 5.02(1) indicates oleic acid will exist almost entirely in the anion form at pH values of 5 to 9 and therefore volatilization from water surfaces is not expected to be an important fate process(2). Oleic acid is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 5.46X10-7 mm Hg(3).

| Soil Adsorption | The Koc of undissociated oleic acid is estimated as 340,000(SRC), using a log Kow of 7.64(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that oleic acid is expected to be immobile in soil. The pKa of oleic acid is 5.02(4), indicating that this compound will exist almost entirely in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5).
