In this paper more than 200 existing relationships for Koc estimations have been reviewed and divided into four categories. Regression equations for the most important classes of non-ionic organic environmental chemicals able to estimate soil adsorption coefficients are summarised, and the advantages and drawbacks of the different approaches are discussed briefly.
Due to the fact that a broad application of the proposed approaches is limited by the quality and comparability of the underlying experimental Koc values reference soils are postulated to create a common basis for the comparison of soil adsorption coefficients. 相似文献
