Abstract

Sediments in Lake Constance have been dated by radiometric methods and lamination counting. Investigations into the concentrations of lead and zinc in the sediments were carried out to get detailed informationabout environmental history. Maximum concentrations were found at thebeginning of the 1960's. The lead maximum contamination occurred 3 years before the zinc maximum and has an unidentified source. The use ofcoal, leaded gasoline or the remobilization within the sediment couldbe excluded to result in the lead maximum. The fluctuations in zinc contamination could be explained with increasing and decreasing pollution (industry, coal burning, building of sewage plants). The greatest fluctuations of both metals occur during periods of great change in theeconomic history of Germany.
