Abstract

Adsorption isotherms of 10 principal organochlorine pesticides on soils were investigated for predicting their fate in environment. The adsorption isotherms were expressed by Freundlich type isotherms and the adsorption constants were approximately in proportion to the organic carbon contents for the general soil samples. The adsorption constants per gram of the organic carbon in soil were in the range from 10 - 10⁴, and the values for chlornitrofen and quintozene were relatively high. The constants were correlated roughly with the octanol-water partition coefficients or solubilities in water.
