Estimation of soil adsorption coefficients of organic compounds by HPLC screening using the second generation of the European reference soil set

The European reference soil set was introduced as common basis for a better comparability of soil sorption data measured within the framework of chemi cal testing of environmental chemicals. The success of the EUROSOILS, as th e set is commonly called, convinced the European Commission's joint Researc h Centre to evaluate the possibility of producing a remake of these unique and new type of reference materials maintaining the principal sorption-cont rolling properties of the soils. In this paper the recently proposed second generation of the EUROSOILS is used to evaluate a HPLC-screening technique for the estimation of soil adsorption coefficients of organic chemicals. I t could be shown that the derived correlations between HPLC capacity factor s of the test substances and the respective soil adsorption coefficients re sulting from batch experiments with the second version of the EUROSOILS agr eed with those derived for the first generation of reference soils at a dif ferent occasion.
