- Compounds and soil:water ratio is shown. Linear isotherms were used for estimation of the Freundlich adsorption coefficient (K
d) and the desorption coefficient (K
des). The squared correlation coefficient (R
2) for linearity of log-transformed values, confidence level for the estimated function (±), and the organic carbon normalised adsorption coefficient (K
oc, cm3/g) is given
