Release in dependence of the liquid-to-solid ratio (L/S) of soils spiked with CdS containing pigments: a pH b conductivity c total organic carbon d redox potential (pE) e Cd concentration f cumulative release of Cd. Different test samples CdSoSlBw10 (dark squares), CdSaSl10 (dark diamonds) CdSoSl10 (dark triangles), CdSoSl1(grey triangles), CdSo (bright triangles), SoSl1 (grey circles) and So (bright circles) were used in duplicates
