| Abstract: | Sorption coefficients (Kp) of several organochlorine insecticides (OCs) in volcanic ash silt from Central Java are presented. Selected experimental and estimated octanol‐water partition coefficient (P) values are used to study log‐log regressions with Kp data collected from the literature (PAHs, chlorophenols, phenylureas, chloro‐s‐triazines, carbamates and organophosphorus insecticides) and those of the OCs determined in the present study. Leaching distances and bioactivities in soil are correlated with the Kp values of the pesticides, and with the organic matter and the water content of the soil. |
