Alternatives for the determination of the soil adsorption coefficient, Koc, of non-ionic organic compounds - a review
In this paper more than 35 existing relationships for K(oc) estimations have been reviewed and divided into 4 categories. Among the listed approaches reverse phase high performance liquid chromatography (RP-HPLC) screening and the use of molecular connectivity indices seem to have the highest potential for an accurate K(oc) prediction. Other methods using the n-octanol 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 K(oc) values reference soils are postulated to create a common basis for the comparison of soil adsorption coefficients.
