Abstract (in english)
   Embankment of meandering river systems in many industrial areas results in formation of artificial oxbow lakes that may act as perennial or intermittent traps for river sediments. Their deposits can be dated using combination of historical and stratigraphic data, providing a good mean to study historical record of contamination transported by rivers. Contamination history over the last few decades is of special significance for Central and Eastern Europe as it can reflect high pollutant levels in the second half of 20th century and the subsequent improvement after the fall of the iron curtain. We studied seven ground penetrating radar (GPR) profiles and three sediment cores. Stratigraphy of the cores was inferred from visible-light spectrophotometry, Xray radiography, grain size analysis and semi quantitative modal analysis of sandy fraction. The sediments were dated using the 137Cs mass activity and combination of stratigraphic and historical data.
