Abstract (in english)
   Various types of sediments (clays to fine-grained sands and sandstones) were characterized using a complex of methods (XRD, petrography, chemical analyses, grain analyses, sorption parameters, grain and pore size analyses etc.) at the Brno branch of the Czech Geological Survey and at the department of Mineralogy, Petrography and Geochemistry of the Faculty of Science, Masaryk University Brno, Flow curves of these rocks were determined in columns. Further on, the sorption isotherms of Hg, Cd, Zn, Cu were studied, as well as the development of pH-Eh conditions during the sorption of solutions with varied metal concentrations and the characteristic of desorption of metals from the sediments (sequential analyses). The capture and penetration of the PAU mixture and the technical mixture of low-chlorinated PCB, OCB and motor oil through various types of rocks was studied.
   The sorption isotherms of the equilibrium distribution for selected organic pollutants in the rock-water system (fluoranthen, lindan, 2,4-dichlorophenol) were also determined. The static sorption capacity of sediments for heavy metals is very different from the amount of metal absorbed in sediments by dynamic sorption. Depending on carbonate content in sediments, the dynamically determined sorption capacity is two times higher than the static sorption. The dynamic tests are therefore recommended for description of real system behaviour. It seems to be much more effective to estimate the character of the interaction processes in the rocks and to determine the dynamics of the capture and release of the contaminants. Column experiments and the modelling of the processes of sorption and desorption of the pollutants are an appropriate tool to learn the dynamics of interactive reactions at the particular localities
