The moss data show the effectiveness of air quality control policies for Germany the metal bioaccumulations decreased between 1990 and 2000 whilst they increased from 2000 to 2005. This investigation is intended to show how the moss data could be used to map atmospheric depositions of Cd and Pb which later on might serve for the calculation of Critical Loads Exceedances. In addition we compared how much heavy metal concentrations in mosses in Germany deviate from background data observed in Greenland. Methods Mapping heavy metals with a high spatial resolution for the German territory was conducted according to the following methodology EMEP deposition maps 50 km by 50 km spatial resolution were intersected within a GIS with Kriging maps on Cd and Pb accumulations in mosses EMEP European Monitoring and Evaluation Programme is a scientifically based and politically driven programme under the Convention on Long-range Transboundary Air Pollution for international co-operation to solve transboundary air pollution problems . Subsequently the statistical relations between the EMEP modelled depositions and the bioaccumulations in mosses were quantified by using regression analysis. The regression functions were used to transform .
