    Context 'Baineann na critéir aicmithe le haghaidh M/vM go háirithe le luach log Koc (comhéifeacht asúcháin ithreach). Is é is luach Koc ann an chomhéifeacht rannach carbón orgánach-uisce, agus léiríonn sé cumas substainte a bheith asúite ar chodán orgánach meán comhthimpeallach soladach amhail ithir, sloda agus dríodar, agus dá bhrí sin, tá gaol inbhéartach idir an luach sin agus a bhfuil d’acmhainneacht ag na substaintí dul isteach i screamhuisce.'

    Definition ratio of a substance concentration sorbed in the organic matter component of soil or sediment to that in the aqueous phase at equilibrium Reference "COM-Terminology Coordination, based on: GERALD R. STEPHENSON, IAN G. FERRIS, PATRICK T. HOLLAND , AND MONICA NORDBERG. 'GLOSSARY OF TERMS RELATING TO PESTICIDES (IUPAC Recommendations 2006)' (4.1.2023). IUPAC."
    Comment "It is the 'distribution coefficient' (Kd) 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."

    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<><><><>"
