Název v původním jazyce

Polychlorinated dibenzo-p-dioxines and dibenzofurans in floodplain soils of the Czech Republic

Popis výsledku v původním jazyce

Floodplains are a dynamic ecosystem where the interaction among various environmental media occurs. A characteristic feature of floodplain systems is a high spatio-temporal heterogeneity which is reproduced by the interactions among processes of erosion,transportation and accumulation of material together with anthropogenic landscape transformation. Due to the chemical properties (persistence and low mobility in soil), the bulk of polychlorinated dibenzo-p-dioxines and dibenzofurans (PCDD/Fs) input ispreserved in the surface layer of soils and concentrations in the soil are related to the cumulative input. As far as risky substances are concerned, riverine floodplains can adopt water quality properties during flooding periods1. When looking into thepotential mobilization of POPs during the flooding, two principal contamination fluxes have to be taken into consideration: -The remobilisation and redistribution of contaminated river sediments, subsequently deposited on the flooded area
