Název v původním jazyce

The sediment of the Hostivar Reservoir (Prague, Czech Republic) as a memory of 45 years of pollution

Popis výsledku v původním jazyce

The purpose of this study was to evaluate the historical pollution of the Hostivař reservoir (largest reservoir in Prague) sediment by metals, PAH and PCB and identify the trends in pollution of aquatic environment.140 cm long core samples, recording the 45-year history of the reservoir, were separated to 5 cm width subsamples (approx. 1,5 year of sedimentation) and analyzed for metals (Cd, Pb, Cu, Zn, Cr, Ni, Al), PAH and PCB. Following methods were used: US EPA 3051 for metals, US EPA 505 and US EPA 8082 A for PCB, and ISO 18287:2006 for PAH. Most of the contaminants had the highest concentration at the beginning of the existence of the reservoir, suggesting that the contamination results from construction activities. Significant decrease of Pb occurred in the second half of the 1990s. It was caused by termination of the addition of lead as a detonation suppressant to the gasoline. Most concentrations of PAHs, PCBs and metals, except copper do not present ecotoxicological risk
