Sewage sludge from Munich has been applied to soils of the Grosslappen farm for 50 years. High concentrations of Zn, Cd, Cu, Cr, Pb and Hg were found in the soils after application of 400 or 700 t dry matter. Cd, Cr and Ni were more readily taken up by crops (wheat, barley, oats, maize, potatoes) than Cu, Co, Pb and Hg. Leaves and stalks generally contained much higher levels than grain of tubers.
