Description of key information

The highest degree of adsorption was obtained in eurosoil 5 (KD 4 mL/g, KOC 63 mL/g). This soil is characterized by the highest organic carbon content with 5.96% and sand with 82% of all tested eurosoils. A weak adsorption, 6% in equilibrium, was observed in eurosoil 1. A KD of 0.3 mL/g and a KOC of 9 mL/g were calculated. This soil is characterised by the highest amount of clay (75%) of all tested eurosoils. No adsorption was observed in eurosoils 2, 3 and 4.
