The catchment is located 30 km ESE from the capital Prague. Reported bulk annual Pb-deposition flux FPb, at TR in the year 1994 was 3.41 kg.km-2.yr-1 gradually decreased to 0.49 kg.km-2.yr-1 in 2001. The decrease is comparable with those observed in Germany and in the USA in the 1970s and 1980s. The total sales ban of leaded gasoline in the Czech Republic since January 2001 was accompanied by a pronounced decrease of the FPb in a single year. The residual Pb-deposition flux is assigned to both: (1) the long-range transport of fine-grained vehicular lead aerosol (with long residence time in the atmosphere) and to (2) the emissions from power plant boilers burning lignite mined in the Czech northwest coal basin. The FPb of lead correlates strongly with those of As, Cd, Cu, Zn and Be, the typical elements of the coal fly ash, at both monitored sites.
