    distribution coefficient | Kd | pesticide soil sorption coefficient | soil/water adsorption coefficient

    Definition the "soil-water" partitioning coefficient and is the ratio of a chemical's sorbed concentration (mg/kg) to the dissolved concentration (mg/L) at equilibrium Reference US EPA. Soil/Water Adsorption Coefficient (Kd) http://www.epa.gov/oecaagct/ag101/pestkd.html [20.1.2011]
    Comment The greater the Kd value, the less likely a chemical will leach or contribute to runoff. A very high value means it is strongly adsorbed onto soil and organic matter and does not move throughout the soil. Higher is better. Pesticides are less likely to leach or occur as surface runoff when the Kd is greater than 5Kd(L/kg) = Sorbed Concentration (mg/kg) / Dissolved Concentration (mg/L).For organics, Kd may be calculated by multiplying Koc (the soil organic carbon-water partitioning coefficient) by foc (the mass fraction of soil organic carbon content), as illustrated below:Kd = Koc x foc For Koc, see IATE:3530100<>
