Distribution coefficient used to evaluate the harm the substance can cause to environment. Higher values indicate higher chance of accumulation of the substance in biological material
The amount of solute in the stationary phase relative to the amount of solute in the mobile phase. It can also be the distribution coefficient, KD.
Ratio of the distribution of a substance between two phases when the heterogeneous system (of two phases) is in equilibrium; the ratio of concentrations (or, strictly speaking, activities) of the same molecular species in the two phases is constant at constant temperature. The partition coefficients most frequently used in acute toxicology are lipid/water and octan-1-ol/water distributions. RT lg OW.
A measure of the extent to which a pesticide is divided between the soil and water phases.
A partition coefficient or distribution coefficient is a measure of differential solubility of a compound in two solvents. The logarithmic ratio of the concentrations of the solute in the solvent is called log P (sometimes LogP). The best known of these partition coefficients is the one based on the solvents octanol and water.
