Chromium and mercury in a soil after 80 years of treatment with urban sewage water . A soil (tab. 1) which is since 80 years under irrigation with sewage water contains 112 ppm Cr and 1.5 ppm Hg (Fig. 1). The sewage water presently contains 0.07 ppm chromium and 0.002 ppm mercury. In order to study the migration and leaching of chromium in the soil experiments were carried out with 51 Cr as CrO 4 2‐ under aerobic and 51 Cr als Cr 3+ under anaerobic conditions in undisturbed soil columns. In all cases chromium was adsorbed in the layer 0–5 cm (Fig. 2 and 3). Similar experiments with 203 Hg as HgCl 2 (Fig. 4) showed that mercury ist adsorbed near the surface. These experiments confirmed our results of ground water analyses, neither chromium nor mercury contaminated the ground water.
