Parameters for predicting fate of organochlorine pesticides in the environment (I) Octanol-water and air-water partition coefficients

Abstract

Octanol-water partition coefficients and air-water partition coefficients of 10 principal organochlorine pesticides were obtained as basic data for predicting their fate in environment. The octanol-water partition coefficients were in the wide range from 10 to 10 6 and approximately correlated with the solubilities in water. The air-water partition coefficients were also in the wide range from 10 −7 to 10 −2, and the values for chloropicrin, dichlorvos, DCIP and quintozene were relatively high.
