The problem of PBT compounds is highly relevant in the context of the CEE countries such as Czech Republic. Measurements that were carried out to map the situation show a high degree of contamination in the environment especially by PCBs (polychlorinated biphenyls) and dioxins (polychlorinated dibenzo p dioxins and dibenzofurans). The national inventory of these pollutants was completed. This inventory contains detailed information on the present state of that field in the Czech Republic with inventories as appropriate. Very broad inventory also summarised and evaluated all available information concerning to PAHs, OCPs, PCBs, PCDDsFs contamination of sediments from main Czech rivers and reservoirs including the evaluation of effects of floods in the years 1997 and 2002. The results of spatial and temporal trends concerning to these types of pollutants in the sediments will be presented and discussed in the relation to the European results of UNEPGEF Project Regionally Based Assessment of Persistent Toxic Substances, which where prepared by authors of presentation too. Key words: Sediments, PBTs, Contamination, Trends |
