The estimated pKas of 7.17, 8.26, 10.13, 12,30, and 13.11(1) indicate quercetin will partially exist 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). Volatilization of quercetin from moist soil surfaces is not expected to be an important fate process because it is an anion and anions do not volatilize(SRC). Quercetin is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 2.8X10-14 mm Hg(SRC), determined from a fragment constant method(3).

The Koc of quercetin is estimated as 460(SRC), using a water solubility of 60 mg/L(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that quercetin is expected to have moderate mobility in soil. The estimated pKas of quercetin are 7.17, 8.26, 10.13, 12,30, and 13.11(4), indicating that this compound will partially exist in the anion form in the environment at neutral pH and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5).
