River systems are the most widespread sedimentary environment in many European countries and can be hence used for study of historical development of contamination and for evaluation of the anthropogenic impact influence at the local or regional level. The study of river sediments, however, is complicated by changes of channel morphology and sedimentation dynamics and redeposition of old sediments, whether caused naturally (flood events) or by human impact (land use changes or building of water management structures), which leads to deposition of various sedimentary facies. Identification of sedimentary facies within floodplain fill is hence necessary - character (lithology) of deposited facies influences the spatial distribution of pollutants within floodplains. Suitable sampling sites strategy and chemostratigraphic correlations of depth profiles guarantee a correct interpretation of obtained data. However, in many countries, there are still no legislative tools or universal methodology for contamination assessment respecting natural variability of sedimentary records. Regional contamination during the last centuries and identification of local pollution sources of risk elements (Pb , Zn , Cu , ...) and magnetic particles have been studied in the sediments of the Morava River, in the area between...
