Abstract (in english)
   Lead originating from coal burning, gasoline burning, and ore smelting was identified in Pb-210-dated profiles through eight Sphagnum dominated peat bogs. Basal peat C-14-dated at 11 000 years BP had relatively high Pb-206/Pb-207 ratio (1.193). Peat deposited around 1800 AD had a lower Pb-206/Pb-207 ratio of 1.168-1.178, indicating that environmental lead in Central Europe had been largely affected by human activity (smelting) even before the beginning of the Industrial Revolution. The highest annual Pb accumulation rates in peat were consistent with the highest Pb emission rates from coal-fired power plants and traffic (1980). The mean measured Pb-206/Pb-207 ratios of local coal, ores, and gasoline were 1.19, 1.16, and 1.11, respectively. A considerable proportion of coal emissions, relative to gasoline emisions, was responsible for the higher Pb-206/Pb-207 ratios in the recent atmosphere (1.15) compared to Western Europe (1.10).
