Forty five-year sedimentary record of priority pollutants (metals, PAH, PCB) in the Hostivar reservoir (Prague, the Czech Republic)

Popis výsledku v původním jazyce

The paper presents results from unique collection of the Hostivař reservoir (Prague, Czech Republic) sediment. The reservoir was built in 1959-1963 and the filling was completed in 1964, since it not been cleaned. Therefore sediment deposited on the bottom may provide information not only about current pollution, but also about the historical pollution by persistent pollutants, as toxic metals, PAHs and PCB. The reservoir was first time completely drained in late summer of 2010 because of planed total sediment dredging. Result show historical load of sediment by priority pollutants. In the case of metals different trends were observed. While Cd and Pb show decreasing trend, in the case of the other metals the trend was not so clear. The highest concentrations of most monitoring metals were found in the deepest layers of sediment (construction of reservoir)l. Most concentration of PAHs, PCBs and toxic metals do not exceed the environmental quality standards.
