Part B of the GEMAS atlas provides a more detailed interpretation of the spatial distribution of selected elements (As, C, Cd, K, Th, U) at the European scale than was possible to provide in Part A, the geochemical atlas. To highlight the importance of scale this part also provides interpretations of the data set at a more local scale (Scandinavia and Ukraine). Possibilities for more-in-depth uses of the data set from assessing the impact of agriculture (carbon stock), through risk assessment to unravelling geological processes (loess distribution) are demonstrated. Several chapters cover the background information needed for the interpretation of a geochemical atlas (geology, soil formation, mineral deposits). Finally, data on the regional distribution of some rarely analysed elements (B, Cl, F) at the European scale are pre- sented, based on the old FOREGS soil samples. A discussion of element concentrations, as measured in a very weak extraction (MMI©), helps to understand the geochemical processes governing the distribution of elements at the European scale, and allows us to better detect the impact of human activities on European agricultural soil. Part B also provides Tables summarising European legislation with regard to soil, and the key statistical parameters for the GEMAS samples.
