A review, with 22 refs. Elution tests (S4, pHstat, and SDS test) are presented, enabling the evaluation of the mobility of hydrophilic/ hydrophobic and inorg./org. contaminants in soil and waste materials. While elution tests for estn. of the mobilization potential of hydrophilic substances are performed following the pHstat method, for hydrophobic species surfactant-contg. eluents are used. The individual parameters of the elution process are selected assuming a \"worst-case\" scenario. In principle, because of economic reasons, detailed anal. investigations should be preceded by relevant screening tests.
