The Fate of Atmospherically Derived Pb in Central European Catchments: Insights from Spatial and Temporal Pollution Gradients and Pb Isotope Ratios
Original language description
Soils in polluted regions are generally regarded as a delayed, long-lasting source for Pb contamination of aquatic systems. Lead deposited on topsoil is slowly transported downward with particulate and colloidal organic matter, driven by infiltrating precipitation. Then, Pb is tightly retained in mineral soil. Lead export from catchments is extremely low and de-coupled from the atmospheric input. We tested this hypothesis in 11 small catchments, differing in pollution levels. Input/ouput Pb fluxes weremonitored for 14-15 years in an era of decreasing industrial Pb emission rates. Between 1996/1997 and 2010, Pb deposition fluxes decreased significantly, on average by 80 %. At the beginning of the monitoring, Pb export constituted 2 to 58 % of Pb input.At the end of the monitoring, Pb export constituted 2 to 95 % of Pb input. Highly polluted sites in the northeast exported significantly more Pb than less polluted sites further south. The 206Pb/207Pb isotope ratios of runoff (1.16) were
