The vertical distribution of eight heavy metals (Hg, Cu, Zn, Cr, Co, Ni, Pb, Cd) in dated sediments of four sedimentary profiles from the central part of Lake Constance was examined. From 1900 to about 1960 - 1970, a general increase of all heavy metals was observed. After this time, the concentrations of most of the metals decreased.
