- Definition the ratio of the mass of a chemical that is adsorbed in the soil per unit mass of organic carbon in the soil per the equilibrium chemical concentration in solution Reference CLARC https://fortress.wa.gov/ Notes on Chemical-Specific Parameters – Physical and Chemical Properties https://fortress.wa.gov/ecy/clarc/FocusSheets/Physical&ChemicalParameters.htm [20.1.2011]
- Comment It is the "distribution coefficient" (Kd) [ IATE:3530105 ] normalized to total organic carbon content. KOC values are useful in predicting the mobility of organic soil contaminants; higher KOC values correlate to less mobile organic chemicals while lower KOC values correlate to more mobile organic chemicals.
