Soil sorption constants based on the organic carbon content (K oc ) of 15 pesticides were measured using two soils at three concentrations. Significant correlations were found between the K oc value and water solubility (WS), octanol/water partition coefficient (K ow ), retention time in reversed‐phase HPLC (R t ) and molecular weight (mol. wt.). Thus the soil sorption constants of nonionic pesticides can be predicted by these four parameters.
