Abstract: In this paper more than 35 existing relationships for Koc estimations have been reviewed and divided into four categories. Among the listed approaches RP-HPLC-screening and the use of molecular connectivity indices seem to have the highest potential for an accurate Koc prediction. Other methods using the n-octagonal water partition coefficient or the chemical's water solubility showed a poorer degree of correlation or were limited to very specific groups of compounds. 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.
