Abstract

The AA. studied 3 cores from a well-dated sediment archive from an oxbow lake of the River Morava, Czech Republic, using a high-resolution (1 cm) multiproxy stratigraphic analysis and a concentration of selected heavy metals. The aim was to investigate how the vertical distribution of pollutants could be affected by episodic flood sedimentation in archives with high sedimentation rates. The long-term trends exhibit decreasing concentrations of most heavy metals for the last 25 years, most notably between 1987 and 1992. These historical patterns correspond well to the significant improvement in environmental pollution reported elsewhere in Central Europe. In contrast, concentrations of Na have systematically increased up until the present, partly being driven by the widespread use of de-icing salt for winter road treatmen
