Abstract
The strength of adsorptivity of a chemical to soils, koc, is the adsorption coefficient, kd, normalized by the organic carbon content in unit mass of soils, Coc. The koc is expected to have constant value for chemical in adsorption to soil, however, the koc value of this chemical proved to be different in different kinds of soil. In this investigation, the relationship between kd and Coc can be expressed as d = Koc · Coc + α for five kinds of soil and five kinds of chemicals, where Koc is defined as an ‘average’ of the contribution of organic matter to kd and intercept α expresses a fraction of adsorption by soil constituents other than organic carbons. The ratio koc to Koc was found to be nearly constant for each type of soil for different chemical species. Therefore, that ratio for each soil type can be used to compensate for changes in koc in different kinds of soil. The compensated koc was closely related to the value of Koc. The compensated koc is useful for comparison of adsorptivity of hydrophobic organic compounds to soil.
